a) The gradient of the line passing through the points (0,6) and (3,0) is -2. b) The gradient of the line perpendicular to this line is 1/2. c) The equation for the line passing through point a and perpendicular to the line ab can be determined using the point-slope form of a linear equation.

a) To find the gradient (slope) of the line passing through (0,6) and (3,0), we use the formula: gradient = (change in y) / (change in x). Substituting the coordinates, we get (-6) / (3-0) = -2.

b) The gradient of a line perpendicular to another line is the negative reciprocal of the original gradient. Therefore, the gradient of the line perpendicular to the given line is 1/2.

c) To find the equation of the line passing through point a and perpendicular to line ab, we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) is point a and m is the gradient of the perpendicular line. Substituting the values, we get y - 6 = (1/2)(x - 0), which simplifies to y = (1/2)x + 6.

Cindy has scores of 72, 82, 83 and 89 on her Biology tests. Cindy must score between 68 and 89 on her final exam to earn a C in Biology.

Cindy's current average score in Biology is:

(72 + 82 + 83 + 89) / 4 = 81.5

Since the final exam counts as two tests, we can calculate the total number of points Cindy can earn in the course as follows:

Total points = 4 tests + 2 tests = 6 tests

To earn a C in the course, her average score must be between 77 and 84. Let's assume she needs to score x on her final exam to achieve a C. Then her total points would be:

Total points = 72 + 82 + 83 + 89 + x + x

Simplifying this equation, we get:

Total points = 326 + 2x

To earn a C, Cindy's average score must be between 77 and 84. Therefore, we can set up an inequality:

77 <= (326 + 2x) / 6 <= 84

Multiplying both sides by 6, we get:

462 <= 326 + 2x <= 504

Subtracting 326 from all sides, we get:

136 <= 2x <= 178

Dividing by 2, we get:

68 <= x <= 89

Therefore, Cindy must score between 68 and 89 on her final exam to earn a C in Biology.

The mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes.

The mean, median, and range of Santos' train ride times for the week were as follows:

Mean: 49.4 minutes

The mean is calculated by adding up all the values and dividing the sum by the total number of values. In this case, the sum of the train ride times (48 + 51 + 48 + 48 + 50) is 245 minutes. Dividing this sum by the total number of days (5), we get the mean of 49.4 minutes.

Median: 48 minutes

The median is the middle value in a sorted list of numbers. To find the median, we arrange the train ride times in ascending order: 48, 48, 48, 50, 51. Since there is an odd number of values, the middle value is the median. In this case, the median is 48 minutes.

Range: 3 minutes

The range is the difference between the largest and smallest values in a set. To calculate the range, we subtract the smallest value (48 minutes) from the largest value (51 minutes). In this case, the range of the train ride times for the week is 3 minutes.

In summary, the mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes. These metrics provide insights into the average, central tendency, and variability of Santos' train rides throughout the week.

The perimeter of the rectangle is 22 7/15 meters, and the area is 29 1/10 square meters.

To find the perimeter of a rectangle, we add the lengths of all four sides. In this case, the length of one side is 4 7/20 meters and the length of the adjacent side is 6 2/3 meters. To add these mixed numbers, we convert them to improper fractions. The first side becomes 87/20 meters and the second side becomes 20/3 meters. Adding the two lengths gives us a total of (87/20 + 20/3) meters. To add fractions with different denominators, we need to find a common denominator. The least common multiple of 20 and 3 is 60. Converting both fractions to have a denominator of 60, we get (261/60 + 400/60) meters, which simplifies to 661/60 meters. Finally, we can convert this improper fraction back to a mixed number, which is 11 1/60 meters. Since the perimeter of a rectangle is the sum of all four sides, the perimeter of this rectangle is 2 times 11 1/60 meters, which equals 22 2/60 meters or 22 7/15 meters.

To find the area of a rectangle, we multiply the length by the width. In this case, the length is 4 7/20 meters and the width is 6 2/3 meters. Converting both mixed numbers to improper fractions, we get a length of 87/20 meters and a width of 20/3 meters. Multiplying these two fractions gives us (87/20 * 20/3) square meters. Simplifying the fractions, we get (1740/60) square meters, which further simplifies to 29 square meters. Therefore, the area of this rectangle is 29 square meters.

I agree with Rita. Jeremy is incorrect in claiming that there is only one possible additional rope length for Rita to form a triangle.

To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, Rita has two rope lengths of 9 feet and 1 foot. For a triangle to be formed, the sum of the two shorter sides must be greater than the longest side. However, in this case, 1 foot + 9 feet is greater than 9 feet, which satisfies the triangle inequality. Therefore, Rita can form a triangle with these two rope lengths.

The new pressure of the balloon at the higher altitude, when it occupies 1.5 L and is at 14.0 °C, is approximately 25.46 atm/°C.

To find the new pressure of the balloon when it is brought to a higher altitude, we can use the combined gas law equation:

P1V1/T1 = P2V2/T2

Given:

P1 = 0.945 atm (initial pressure)

V1 = 3 L (initial volume)

T1 = 39.0 °C (initial temperature)

V2 = 1.5 L (final volume)

T2 = 14.0 °C (final temperature)

Substituting the given values into the equation, we have:

(0.945 atm)(3 L)/(39.0 °C) = P2(1.5 L)/(14.0 °C)

Simplifying the equation:

2.727 atm/°C = 0.1071P2

To isolate P2, we divide both sides by 0.1071:

P2 = 2.727 atm/°C / 0.1071

P2 ≈ 25.46 atm/°C

The original price of the refurbished phone before the 35% discount was £120. If a refurbished phone is sold at a 35% discount with a final price of £78.

To find the original price of a refurbished phone before the discount of 35%, let's use the following formula:

discount = original price - discounted price

35% of the original price can be represented as 0.35 times the original price. This will result in the equation below:

0.35x = original price - 78

Where x is the original price. So, to find the value of x, we can rearrange the equation to get:

0.35x + 78 = original price

Now we substitute the given values into the equation above:

0.35x + 78 = original price

0.35x + 78 = x - 44.1 (if x represents the original price)

Let's subtract 0.35x from both sides to isolate the x variable:

The cheetah can reach speeds of up to 70 miles per hour (112 kilometers per hour) in short bursts. Assuming the cheetah maintained its maximum speed throughout the entire 10-minute sprint, we can estimate the distance traveled.

To estimate the distance traveled by the cheetah, we can calculate the distance covered by assuming a constant speed. The maximum speed of a cheetah is typically cited as 70 miles per hour.

First, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, 10 minutes is equal to 10/60 = 1/6 hour.

Distance = Speed × Time

Distance = 70 miles per hour × (1/6) hour

Distance ≈ 11.67 miles

Therefore, if the cheetah maintained its maximum speed of 70 miles per hour throughout the entire 10-minute sprint, it would have traveled approximately 11.67 miles.

The missing side lengths are x = 4 and y = 4.The correct answer choice is D) x = 4, y = 4.

To find the missing side lengths in a triangle, we can use trigonometric ratios. In this case, we are given the length of one side (8) and the measure of one angle (30 degrees), and we need to find the lengths of the other two sides (x and y).

In a right triangle, the trigonometric ratios can be used to relate the angles and side lengths. In this case, we are not given that the triangle is a right triangle, so we will assume it is not.

The sine ratio relates the ratio of the length of the side opposite an angle to the length of the hypotenuse. In this case, the side opposite the 30-degree angle is y, and the hypotenuse is 8. So we can write:

sin(30 degrees) = y/8

Using the known value of sin(30 degrees) = 1/2, we can solve for y:

1/2 = y/8

Cross-multiplying, we get:

y = 4

So we have found the length of side y to be 4.

To find the length of side x, we can use the law of sines. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.

Using the law of sines, we can write:

sin(30 degrees)/x = sin(angle opposite x)/8

Since we know the sine of 30 degrees is 1/2, we can rewrite the equation as:

(1/2)/x = sin(angle opposite x)/8

Since the angle opposite x is 180 degrees - 30 degrees = 150 degrees, we have:

(1/2)/x = sin(150 degrees)/8

Using the known value of sin(150 degrees) = 1/2, we can solve for x:

(1/2)/x = 1/2/8

Cross-multiplying, we get:

x = 4

So we have found the length of side x to be 4.

Therefore, the missing side lengths are x = 4 and y = 4.

The correct answer choice is D) x = 4, y = 4.

The inequality that represents the largest number of food Sammy can buy, given her budget, is 2.75x ≤ 43.75 - 9.25, where x represents the number of food items she can purchase.

To find the inequality representing the largest number of food items Sammy can buy, we need to consider her budget and the cost of admission and food. Let x be the number of food items she can purchase.

The cost of admission is $9.25, which needs to be subtracted from her total budget. The remaining amount can be used to purchase food. Each food item costs $2.75.

Therefore, the inequality can be written as 2.75x ≤ 43.75 - 9.25, where the left side represents the cost of the food (2.75x), and the right side represents the remaining budget after deducting the admission fee (43.75 - 9.25).

Therefore, 400m of wire will be needed to put a double fence around a square plot with 50m.Long Answer:The given plot is a square with the side of the square being 50m. To find out the amount of wire needed to put a double fence around the square plot, we first need to calculate the perimeter of the square plot.A square is a 4 sided figure with all sides of equal length.

Therefore, the perimeter of a square can be calculated by multiplying the length of one side of the square with 4, as shown below.Perimeter of a square = 4 x SideWhere Side is the length of one side of the square plot.In this case, the side of the square plot is given as 50m. Therefore, the perimeter of the square plot can be calculated as shown below:Perimeter of a square = 4 x 50m = 200mTherefore, the perimeter of the square plot is 200m.Now, since we need to put a double fence around the square plot, we will multiply the perimeter by 2. This is because a double fence means that we will be putting two fences back to back around the perimeter of the square plot. Therefore, the total length of wire needed for double fencing can be calculated as shown below:Total length of wire needed for double fencing = 2 x Perimeter of the square plotTotal length of wire needed for double fencing = 2 x 200mTotal length of wire needed for double fencing = 400mTherefore, 400m of wire will be needed to put a double fence around a square plot with 50m.

A van can carry 12 students, and a bus can carry 36 students. The senior class at NAHS rented and filled 6 vans and 12 buses with 504 students.

To determine how many students a van can carry and how many students a bus can carry, we can use a system of equations based on the given information.

Let's assume that the number of students a van can carry is "v" and the number of students a bus can carry is "b".

According to the information provided:

The senior class at NAHS rented and filled 6 vans and 12 buses with a total of 504 students.

The senior class at FCHS rented and filled 2 vans and 5 buses with a total of 204 students.

Based on these conditions, we can form the following equations:

Equation 1: 6v + 12b = 504

Equation 2: 2v + 5b = 204

We now have a system of two equations with two unknowns (v and b). We can solve this system to find the values of v and b.

Let's solve the system using any preferred method, such as substitution or elimination.

Multiplying Equation 2 by 6, we get:

12v + 30b = 1224

Subtracting this equation from Equation 1, we can eliminate v:

6v + 12b - (12v + 30b) = 504 - 1224

-6v - 18b = -720

Simplifying this equation, we get:

-6v - 18b = -720

Dividing this equation by -6, we obtain:

v + 3b = 120

Now we have a new equation:

v + 3b = 120 -------------- Equation 3

We can now solve Equations 2 and 3 as a new system of equations.

Multiplying Equation 3 by 2, we get:

2v + 6b = 240

Subtracting this equation from Equation 2, we can eliminate v:

2v + 5b - (2v + 6b) = 204 - 240

b = -36

Dividing both sides of the equation by -1, we find:

b = 36

Now, substituting the value of b back into Equation 3:

v + 3(36) = 120

v + 108 = 120

v = 12

Therefore, a van can carry 12 students, and a bus can carry 36 students.

Answer:

Step-by-step explanation:

To enlarge a 4x6 photo with a ratio of 2:3, we can multiply the dimensions of the photo by the enlargement ratio to find the new dimensions.

Original photo dimensions: 4 inches x 6 inches

Enlargement ratio: 2:3

To find the new dimensions, we can multiply the original dimensions by the enlargement ratio:

New width = 4 inches x 2 = 8 inches

New height = 6 inches x 3 = 18 inches

Therefore, the new dimensions of the enlarged photo would be 8 inches x 18 inches.
