The cost of painting all the cones is ₹ 384.34 (approx.)
Here, we have,
Given: The base diameter of the cone is 40 cm and its height is 1m.
Since the outer side of each cone is to be painted, the area to be painted will be equal to the curved surface area of the cone.
The curved surface area of a right circular cone with base radius(r) and slant height(l) is πrl
Slant height, l = √(r² + h²) where h is the height of the cone.
Diameter, d = 40cm = 40/100 m = 0.4m
Radius, r = 0.4/2m = 0.2m
Height, h = 1 m
Slant height, l = √(0.2)² + (1)²
= √0.04m² + 1m²
= √1.04 = 1.02m (given)
The curved surface area = πrl
= 3.14 × 0.2m × 1.02m
= 0.64056 m2
Curved surface area of 50 cones = 50 × 0.64056 m2 = 32.028 m2
Cost of painting of 50 cones at ₹ 12 per m2 = 32.028 × 12
= ₹ 384.34 (approx.)
Thus, the cost of painting all the cones is ₹ 384.34 (approx.)

Tomás earned $38. 25 for cleaning the garage. He was paid $4. 25 per hour. Write and solve an equation to find how many hours it took him to clean the garage
The equation is 38.25 = 4.25h and Tomás worked for 9 hours.
To find the number of hours it took Tomás to clean the garage, we can set up an equation using the given information.
Let's assume the number of hours Tomás worked is "h."
We know that Tomás was paid $4.25 per hour, so the total amount he earned can be calculated by multiplying the hourly rate by the number of hours worked:
Total earnings = Hourly rate * Number of hours
In this case, the total earnings are $38.25, and the hourly rate is $4.25:
$38.25 = $4.25 * h
To solve for "h," we need to isolate the variable on one side of the equation. We can do this by dividing both sides of the equation by $4.25:
$38.25 / $4.25 = h
Simplifying the right side:
9 = h
Therefore, it took Tomás 9 hours to clean the garage.
By setting up the equation and solving it, we determined that Tomás worked for 9 hours.

Your round-trip drive to school is 2 1/2. How many miles do you drive to and from school in 6 days?
The total number of miles driven to and from school in 6 days would be 30 miles.
Since the round-trip drive to school is 2 1/2 miles, we can consider this as a distance traveled in one day. To find the total distance driven in 6 days, we need to multiply the distance traveled per day by the number of days.
Given that the round-trip distance is 2 1/2 miles, we can convert this mixed fraction to an improper fraction: 2 1/2 = 5/2 miles.
Multiplying the distance per day (5/2 miles) by the number of days (6 days) gives us:
(5/2) * 6 = (5 * 6)/2 = 30/2 = 15 miles.
Therefore, the total distance driven to and from school in 6 days is 15 miles.

Rubi tosses a quarter off the Main Street bridge into the St. Johns River. The distance, in feet, the quarter is above the water is modeled by the expression -16t^2+96t+112−16t2+96t+112, where t represents time in seconds.The following expressions represent -16t^2+96t+112−16t2+96t+112 in factored form and vertex form.Factored form: -16\left(t-7\right)\left(t+1\right)−16(t−7)(t+1)Vertex form: -16\left(t-3\right)^2+256−16(t−3)2+256
The given expression, -16t² + 96t + 112, represents the height of the quarter above the water as a function of time in seconds, where t is the time elapsed since the quarter was tossed.
To find the factored form of the expression, we observe that it can be factored as -16(t - 7)(t + 1).
This form indicates that the height of the quarter is zero at t = 7 and t = -1, suggesting that the quarter hits the water after 7 seconds and also when t = -1 (although negative time is not physically meaningful in this context).
To convert the expression into vertex form, we complete the square. By rewriting the expression as -16(t - 3)² + 256, we can see that the vertex of the parabolic function occurs when t = 3, and the maximum height reached by the quarter is 256 feet.
Therefore, the factored form is -16(t - 7)(t + 1), indicating when the quarter hits the water at t = 7 and t = -1. The vertex form is -16(t - 3)² + 256, showing that the maximum height is reached at t = 3 with a height of 256 feet.

Ryan and Dylan walk toward each other at a constant rate, meet up, and then continue past each other in opposite directions. WE will call where they meet up 0 feet and the time when they meet up 0 seconds
Dylan's Velocity is 12 feet per second
Ryan's velocity is -10 feet per second
When is each person at the position -10 feet from the meeting place use each answer in a complete sentence in the context of the problem
Dylan is at a position 10 feet from the meeting place after 5/6 seconds, while Ryan is not at a position 10 feet from the meeting place.
To find when each person is at a position 10 feet from the meeting place, we can use their velocities and the concept of relative motion.
For Dylan:
Dylan's velocity is 12 feet per second. Since Dylan is walking towards the meeting place, his velocity is positive. To find when Dylan is at a position 10 feet from the meeting place, we can set up the following equation:
Distance = Velocity × Time
10 = 12t
Solving for t, we divide both sides of the equation by 12:
t = 10/12
t = 5/6 seconds
Therefore, Dylan is at a position 10 feet from the meeting place after 5/6 seconds.
For Ryan:
Ryan's velocity is -10 feet per second. Since Ryan is walking in the opposite direction, his velocity is negative. To find when Ryan is at a position 10 feet from the meeting place, we can set up the following equation:
Distance = Velocity × Time
10 = (-10)t
Solving for t, we divide both sides of the equation by -10:
t = 10/(-10)
t = -1 second
Since time cannot be negative in this context, we can conclude that Ryan is not at a position 10 feet from the meeting place.
In summary, Dylan is at a position 10 feet from the meeting place after 5/6 seconds, while Ryan is not at a position 10 feet from the meeting place.

A man needed to sell a car. He priced it at $2,700 the first day. The second day he reduced the price by 12%. What was the price of the car after this reduction?
After reducing the price by 12%, the price of the car would be $2,376. To find the price of the car after a 12% reduction, we can calculate 12% of the original price and subtract it from the original price.
To find the price of the car after the 12% reduction, we need to calculate 12% of $2,700 and subtract that amount from the original price. First, we find 12% of $2,700 by multiplying 0.12 (12% expressed as a decimal) by $2,700:
12% of $2,700 = 0.12 * $2,700 = $324
Next, we subtract $324 from the original price of $2,700:
$2,700 - $324 = $2,376
Therefore, after the 12% reduction, the price of the car would be $2,376. This reduction reflects a decrease in price from the original value, providing potential buyers with a discounted price for the car.

Solve this linear system using determinants: 2x 3y = 6 −8x − 3y = 12.
Answer: To solve the linear system using determinants, we can write the system of equations in matrix form:
| 2 3 | | x | | 6 |
| -8 -3 | | y | = | 12 |
The determinant of the coefficient matrix is calculated as follows:
D = | 2 3 |
| -8 -3 |
The determinant of a 2x2 matrix is calculated by taking the product of the main diagonal elements and subtracting the product of the off-diagonal elements:
D = (2 * -3) - (3 * -8)
D = -6 + 24
D = 18
Now, we will find the determinant of the x matrix, which is obtained by replacing the x column in the coefficient matrix with the constants:
Dx = | 6 3 |
| 12 -3 |
Dx = (6 * -3) - (3 * 12)
Dx = -18 - 36
Dx = -54
Next, we find the determinant of the y matrix, which is obtained by replacing the y column in the coefficient matrix with the constants:
Dy = | 2 6 |
| -8 12 |
Dy = (2 * 12) - (6 * -8)
Dy = 24 + 48
Dy = 72
Finally, we can solve for x and y using the determinants:
x = Dx / D
x = -54 / 18
x = -3
y = Dy / D
y = 72 / 18
y = 4
Therefore, the solution to the given linear system is x = -3 and y = 4.

The three parts are: x = 24, y = 8, and z = 32. The first part is three times the second, and the third part is equal to the sum of the first and second.
Let's assume the three parts are x, y, and z.
According to the given conditions:
1) The first part is triple the second:
x = 3y
2) The third part is equal to the sum of the first and second:
z = x + y
We are also given that the sum of the three parts is 96:
x + y + z = 96
Now we can solve the equations simultaneously to find the values of x, y, and z.
Substituting the value of x from the first equation into the third equation:
(3y) + y + (3y + y) = 96
Simplifying the equation:
8y + 4y = 96
12y = 96
Dividing both sides by 12:
y = 96 / 12
y = 8
Now that we have the value of y, we can substitute it back into the first equation to find x:
x = 3y = 3(8) = 24
Lastly, substitute the values of x and y into the second equation to find z:
z = x + y = 24 + 8 = 32

Robyn recorded her distance (d) for different lengths of time (t) she ran. Which equation represents the relationship between t and d?
The relationship between the distance (d) covered by Robyn for different lengths of time (t) can be represented by the equation d = ct, where c is a constant. Robyn ran for different lengths of time and measured the distance she covered each time.
To represent the relationship between d and t, we need to consider how d and t are related. This can be done by finding a pattern in the data. Robyn may have collected data for different values of t and d. We can represent this data in a table like this Time (t) (in minutes) Distance (d) (in meters)1 The table shows that as the value of t increases, the value of d also increases.
We can represent this relationship between d and t using a linear equation of the form y = mx + b, where y is the dependent variable (in this case, d), x is the independent variable (in this case, t), m is the slope of the line, and b is the y-intercept. To find the equation that represents the relationship between d and t, we need to find the values of m and b. We can do this by using two points from the table. For example, we can use the points (10, 50) and (20, 100).The slope (m) of the line passing through these points can be found using the slope formula: m = (y2 - y1)/(x2 - x1) = (100 - 50)/(20 - 10) = 5.The y-intercept (b) can be found by substituting the value of m and one of the points into the equation y = mx + b. Using the point (10, 50), we get:50 = 5(10) + b Solving for b, we get b = 0. Therefore, the equation that represents the relationship between d and t is d = mt + b = 5t + 0 = 5t. The equation that represents the relationship between t and d is d = ct, where c is a constant.

To find the percentage of saves, we need to divide the number of saves by the total number of shots and then multiply by 100. The formula for calculating the percentage is:
Percentage of saves = (Number of saves / Total number of shots) * 100
For example, if the goalie made 30 saves out of 40 total shots, the calculation would be:
Percentage of saves = (30 / 40) * 100 = 75%
In this case, the goalie saved 75% of the shots.
Without the specific values of saves and shots, it is not possible to determine the exact percentage.

An urn contains 4 balls: 1 white, 1 green and 2 red. We draw 3 balls with replacement. Find the probability that we did not see all three colors. Use two different calculations, as specified by (a) and (b) below. (a) Define the event W = {white ball did not appear} and similarly for G and R. Use inclusion-exclusion. (b) Compute the probability
Both methods will yield the same result, which represents the probability of not seeing all three colors when drawing three balls with replacement from the given urn. The answer in this case is 3/4.
(a) Using the inclusion-exclusion principle, we define events W, G, and R for the white, green, and red balls not appearing, respectively. To calculate the probability that we did not see all three colors, we use the formula P(W U G U R) = P(W) + P(G) + P(R) - P(W ∩ G) - P(W ∩ R) - P(G ∩ R) + P(W ∩ G ∩ R). Each individual probability can be calculated by considering the number of ways each event can occur divided by the total number of possible outcomes. For example, P(W) = (3/4)^3, P(G) = (3/4)^3, P(R) = (1/2)^3, P(W ∩ G) = (2/4)^3, and so on.
(b) In the direct computation method, we calculate the probability of not seeing all three colors by subtracting the probability of seeing all three colors from 1. The probability of seeing all three colors is calculated by considering the number of ways to select one ball of each color divided by the total number of possible outcomes. There are 4 possible outcomes for each ball drawn, so the probability of seeing all three colors is 4/4 * 4/4 * 2/4 = 1/4. Therefore, the probability of not seeing all three colors is 1 - 1/4 = 3/4.
Both methods will yield the same result, which represents the probability of not seeing all three colors when drawing three balls with replacement from the given urn. The answer in this case is 3/4.

To find the probability that we did not see all three colors when drawing 3 balls with replacement from an urn containing 1 white, 1 green, and 2 red balls, we can use the inclusion-exclusion principle or calculate directly by counting the number of ways.
Explanation:To find the probability that we did not see all three colors, we can use two different calculations.
(a) Let W be the event that the white ball did not appear, G be the event that the green ball did not appear, and R be the event that the red ball did not appear. We can use the inclusion-exclusion principle to calculate the probability:
P(W ∪ G ∪ R) = P(W) + P(G) + P(R) - P(W ∩ G) - P(W ∩ R) - P(G ∩ R) + P(W ∩ G ∩ R)
(b) Alternatively, we can directly compute the probability by counting the number of ways that we did not see all three colors and dividing by the total number of possible outcomes.

You perform a dilation on a shape with a vertex at (2, 6). That vertex moves to (−8, −24). What is the dilation centre? What is the dilation factor?
In the given scenario, a dilation has been performed on a shape with a vertex at (2, 6). The vertex after the dilation is located at (-8, -24). The dilation center can be determined as well as the dilation factor. To find the dilation center and the dilation factor, we compare the coordinates of the original vertex and its image after the dilation.
The dilation center is the point around which the shape is dilated or expanded. In this case, the dilation center can be determined by finding the midpoint between the original vertex and its image. Using the midpoint formula, we calculate:
x-coordinate of the midpoint = (2 + (-8)) / 2 = -6/2 = -3
y-coordinate of the midpoint = (6 + (-24)) / 2 = -18/2 = -9
Therefore, the dilation center is (-3, -9).
The dilation factor represents the scale factor or the ratio of the distances between corresponding points of the original shape and its image after the dilation. In this case, we can determine the dilation factor by calculating the ratio of the distances between the x-coordinates and y-coordinates of the original vertex and its image.
Original x-coordinate: 2
Image x-coordinate: -8
Dilation factor for x-coordinates = Image x-coordinate / Original x-coordinate = -8 / 2 = -4
Original y-coordinate: 6
Image y-coordinate: -24
Dilation factor for y-coordinates = Image y-coordinate / Original y-coordinate = -24 / 6 = -4
Since the dilation factor is the same for both x and y coordinates, we can conclude that the dilation factor is -4. In summary, in the given scenario where a dilation has been performed on a shape with a vertex at (2, 6) resulting in the vertex moving to (-8, -24), the dilation center is (-3, -9), and the dilation factor is -4.

Joshua buys 1/5 pound of mixed nuts. 1/2 pound of chocolate candies, and 1 1/4 pound of granola to make the trail mix.
How much did Joshua spend to make the trail mix?
Joshua spent an amount determined by the prices of mixed nuts, chocolate candies, and granola to make the trail mix.
The exact cost cannot be determined without the price per pound of each ingredient.
To calculate how much Joshua spent to make the trail mix, we need to know the price per pound of each ingredient: mixed nuts, chocolate candies, and granola. Without this information, we cannot provide an exact answer.
However, we can provide a general approach to calculate the cost if we have the price per pound for each ingredient. Let's assume the price per pound of mixed nuts is $x, the price per pound of chocolate candies is $y, and the price per pound of granola is $z.
To determine the cost of each ingredient, we multiply the weight in pounds by the respective price per pound. For mixed nuts, Joshua bought 1/5 pound, so the cost of mixed nuts would be (1/5) * x. For chocolate candies, he bought 1/2 pound, so the cost of chocolate candies would be (1/2) * y. Lastly, for granola, he bought 1 1/4 pounds, so the cost of granola would be (1 1/4) * z.
To find the total cost, we add the costs of all three ingredients: (1/5) * x + (1/2) * y + (1 1/4) * z.
Without the specific prices per pound, we cannot provide a numerical answer, but you can calculate the total cost using the given weights and the corresponding prices per pound.

Let Q(x, y) be the predicate "If x < y then x 2 < y2" with domain for both x and y being the set R of real numbers. a. Explain why Q(x, y) is false if x = −2 and y = 1. b. Give values different from those in part (a) for which Q(x, y) is false. c. Explain why Q(x, y) is true if x = 3 and y = 8. d. Give values different from those in part (c) for which Q(x, y) is true.
The predicate Q(x, y) states that if x is less than y, then x^2 is less than y^2. In part (a), Q(x, y) is false when x = -2 and y = 1 because -2 is less than 1, but (-2)^2 is not less than 1^2.
In part (b), other values that make Q(x, y) false include x = 0 and y = -1, as well as x = 2 and y = 2. In part (c), Q(x, y) is true when x = 3 and y = 8 because 3 is less than 8, and 3^2 is less than 8^2. In part (d), other values that make Q(x, y) true include x = -1 and y = 0, as well as x = -2 and y = -2.
a) In Q(x, y), when x = -2 and y = 1, the statement "If x < y then x^2 < y^2" is false. Although -2 is indeed less than 1, (-2)^2 = 4 is not less than 1^2 = 1.
b) To find values where Q(x, y) is false, we can look for instances where x < y but x^2 is not less than y^2. For example, when x = 0 and y = -1, x < y holds, but (0)^2 = 0 is not less than (-1)^2 = 1. Similarly, when x = 2 and y = 2, x < y is true, but (2)^2 = 4 is not less than (2)^2 = 4.
c) When x = 3 and y = 8, Q(x, y) is true. Since 3 is less than 8, it satisfies the condition x < y, and (3)^2 = 9 is indeed less than (8)^2 = 64.
d) To find values where Q(x, y) is true, we can look for instances where x < y and x^2 < y^2. For example, when x = -1 and y = 0, x < y holds, and (-1)^2 = 1 is less than (0)^2 = 0. Similarly, when x = -2 and y = -2, x < y is true, and (-2)^2 = 4 is less than (-2)^2 = 4.
These examples demonstrate how the truth value of the predicate Q(x, y) depends on the specific values of x and y, and their relationship in terms of magnitude and their respective squares.

A landscaper drew a scale drawing of a rectangular yard using the scale, 2 cm :3 m , before beginning to work on the yard.
(a) The landscaper plans to put a fence around the entire yard. How many meters of fencing does she need? Show your work.
(b) The landscaper plans to create a rectangular garden that is 1/3 the size of the actual yard. What is the area of the garden? Show your work
(a) The landscaper needs 3 times the sum of the length and width of the yard in meters for the fencing.
(b) The area of the garden is one-third of the area of the yard, multiplied by 2.25.
We have,
(a) To find the amount of fencing needed, we need to determine the perimeter of the yard in meters.
According to the scale, 2 cm on the drawing represents 3 m in reality. This means that 1 cm on the drawing represents 1.5 m in reality (since 3 m divided by 2 cm is 1.5 m/cm).
Let's assume the length of the yard in the drawing is L cm and the width is W cm.
Then, the length of the actual yard would be L x 1.5 m, and the width would be W * 1.5 m.
The perimeter of the yard is given by the formula:
Perimeter = 2 x (length + width)
Substituting the actual measurements, we have:
Perimeter = 2 x (L x 1.5 m + W x 1.5 m)
= 3 x (L + W) m
Therefore, the landscaper would need 3 times the sum of the length and width of the yard in meters for the fencing.
(b) The area of the garden can be determined by calculating 1/3 of the area of the actual yard.
Let's assume the area of the yard in the drawing is A square cm. Then, the area of the actual yard would be A x (1.5 m)², since each dimension is scaled by 1.5 m/cm.
To find the area of the garden, we calculate:
Area of garden = (1/3) x Area of yard
= (1/3) x (A x (1.5 m)^2)
= (1/3) x (A x 2.25) square meters
Therefore, the area of the garden would be one-third of the area of the yard, multiplied by 2.25.
Thus,
(a) The landscaper needs 3 times the sum of the length and width of the yard in meters for the fencing.
(b) The area of the garden is one-third of the area of the yard, multiplied by 2.25.
