(PLEASE HELP I NEED IT) Banu will build a fence around a rectangular


30-foot-by-25-foot play area. Given that fencing costs $4. 05 per foot, how much will the fencing cost for Banu to completely surround the play area?

Answers

Answer 1

The fencing cost for Banu to completely surround the play area is approximately $3,105.

To calculate the fencing cost, we need to determine the perimeter of the rectangular play area, which is the sum of all four sides. The length of the play area is 30 feet, and the width is 25 feet. The perimeter is then calculated as 2 * (length + width) = 2 * (30 + 25) = 2 * 55 = 110 feet. Multiply the perimeter by the cost per foot to find the total fencing cost: 110 feet * $4.05/foot = $445.50. Therefore, the fencing cost for Banu to completely surround the play area is approximately $3,105.

On Thursday, she hiked with a friend for 4 miles. On Saturday, she hiked for 5 miles. On Sunday, she hiked for 4 miles. If she hiked a total of 340 minutes all week and it takes her the same amount of time to hike each mile, how many minutes does it take her to hike each mile?

Answers

If Tamara hiked a total of 340 minutes and her goal is to hike for at least 350 minutes every week, it means she fell short by 10 minutes.

Since it takes her the same amount of time to hike each mile, we can calculate the time it takes her to hike each mile.

On Thursday, she hiked a total of 1 + 3 + 4 = 8 miles. On Saturday and Sunday, she hiked a total of 5 + 4 = 9 miles. So in total, she hiked 8 + 9 = 17 miles.

To find the time it takes her to hike each mile, we divide the total time she hiked (340 minutes) by the total distance she covered (17 miles). Therefore, it takes her 340/17 = 20 minutes to hike each mile.

Dawn is making an abstract painting with two triangles. The dimensions of the painting are shown below: Two triangles share the same height of 8 inches. One triangle has a base of 6 inches and the other is 10 inches. The total area of the two triangles is _____ square inches. Numerical Answers Expected! Answer for Blank 1:.

Answers

To find the total area of the two triangles, we need to calculate the area of each triangle and then add them together.

The formula for the area of a triangle is given by:

Area = (base * height) / 2

For the first triangle:

Base = 6 inches

Height = 8 inches

Area of the first triangle = (6 * 8) / 2 = 48 / 2 = 24 square inches

For the second triangle:

Base = 10 inches

Height = 8 inches

Area of the second triangle = (10 * 8) / 2 = 80 / 2 = 40 square inches

Now, we can find the total area of the two triangles by adding their individual areas together:

Total area = Area of the first triangle + Area of the second triangle

Total area = 24 square inches + 40 square inches = 64 square inches

Therefore, the total area of the two triangles is 64 square inches.

Side two of triangle is for more units inside won the third triangle is three times the length of side one is the perimeter of a triangle is 39 units right and solve the equation to find the length of all three sides of the triangle

Answers

the lengths of the three sides of the triangle are approximately:

Side one: 4.875 units

Side two: 19.5 units

Side three: 14.625 units

Let's denote the lengths of the sides of the triangle as follows:

Side one: x

Side two: 4x (since it is four times the length of side one)

Side three: 3x (since it is three times the length of side one)

The perimeter of a triangle is the sum of the lengths of all three sides. In this case, the perimeter is given as 39 units. We can set up an equation to solve for x:

x + 4x + 3x = 39

Combining like terms:

8x = 39

Dividing both sides by 8:

x = 39/8

Simplifying the fraction:

x = 4.875

Now, we can find the lengths of all three sides by substituting this value of x back into our expressions for each side:

Side one: x = 4.875 units

Side two: 4x = 4.875 * 4 = 19.5 units

Side three: 3x = 4.875 * 3 = 14.625 units

The range for the given domain of function f(x)= 3x-6 over x +4. 5 is what

Answers

The range of the function f(x) is all real numbers except for -6.

To find the range of the function, we need to consider the behavior of the function as x approaches certain values. The denominator of the function is x + 4.5, which means the function is undefined when x = -4.5, as division by zero is not defined.

When x approaches -4.5 from the left side (x < -4.5), the function values become increasingly negative. Similarly, when x approaches -4.5 from the right side (x > -4.5), the function values become increasingly positive.

Since the function is undefined at x = -4.5, we exclude that value from the range. Therefore, the range of the function f(x) is all real numbers except for -6. In interval notation, the range can be expressed as (-∞, -6) ∪ (-6, ∞).

WILL GIVE BRAINLIST PLEASE HELP!

Answers

The volume of the square pyramid is 1568 cubic inches. Given that the pyramid has a perimeter of 56 inches, we can determine the length of each side of the square base.

To find the volume of a square pyramid, we need to know the length of the base and the height of the pyramid.

Since a square has all sides equal in length, we divide the perimeter by 4 (the number of sides) to find the length of each side:

Length of each side = 56 inches / 4 = 14 inches

Now, we need to find the height of the pyramid. The slant height given is the distance from the apex of the pyramid to the midpoint of one of the sides. To find the height, we need to use the Pythagorean theorem.

The slant height represents the hypotenuse of a right triangle, with one leg being half the length of the base side and the other leg being the height. Let's call the half of the base length "a" and the height "h."

Using the Pythagorean theorem, we have:

a^2 + h^2 = slant height^2

Since the base side is half the length of the perimeter, we have:

a = 14 inches / 2 = 7 inches

Plugging in the values, we get:

7^2 + h^2 = 25^2

49 + h^2 = 625

h^2 = 625 - 49

h^2 = 576

h = √576

h = 24 inches

Now that we have the length of the base (14 inches) and the height (24 inches), we can calculate the volume of the pyramid using the formula:

Volume = (1/3) * base area * height

The base area of a square is given by side length squared:

Base area = (14 inches)^2 = 196 square inches

Plugging in the values, we have:

Volume = (1/3) * 196 square inches * 24 inches

Volume = (1/3) * 4704 cubic inches

Volume = 1568 cubic inches

A mixture of raisins and almonds is to be sold for $2.55/kg. Almonds sell for $9/kg , and raisins sell for $1.50/kg. If a 20kg mixture, in total, is to be created, how many kg of this mixture should be almonds?

Answers

To create a 20kg mixture of raisins and almonds that sells for $2.55/kg, the amount of almonds in the mixture should be 15kg.

To find the amount of almonds in the mixture, let's assume x represents the amount of almonds in kg. Since the total mixture weighs 20kg, the amount of raisins would be 20kg - x kg.

The cost of the almonds in the mixture can be calculated by multiplying the price per kg of almonds ($9/kg) by the amount of almonds (x kg). Similarly, the cost of the raisins in the mixture is found by multiplying the price per kg of raisins ($1.50/kg) by the amount of raisins (20kg - x kg).

According to the given condition, the total cost of the mixture is $2.55/kg multiplied by the total weight of the mixture (20kg).

Setting up the equation:

($9/kg * x kg) + ($1.50/kg * (20kg - x kg)) = $2.55/kg * 20kg

Simplifying and solving the equation, we find x = 15kg.

The circle is inscribed within the square, and its diameter is given as 60 cm. The radius of the circle is half the diameter, so the radius is 60 cm / 2 = 30 cm. The area of the circle can be calculated using the formula A = πr², where A is the area and r is the radius.

Substituting the values, the area of the circle is A = π(30 cm)² = 900π cm².

To calculate the shaded area, we subtract the area of the circle from the area of the square: Shaded Area = 6400 cm² - 900π cm².

To obtain a numerical approximation, we can use the value of π as approximately 3.14: Shaded Area ≈ 6400 cm² - 900(3.14) cm².

Therefore, the shaded area is approximately 6400 cm² - 2826 cm² ≈ 3574 cm².

The sum of the interior angles of the polygon is 540 degrees. Create an equation to solve for x:



Part 2: Find the measure of x, then find the measures of each unknown angles

Answers

 To find the measure of x and the unknown angles in a polygon, we can create an equation based on the sum of the interior angles, which is 540 degrees.final answer is 108°.

Let's assume the polygon has n sides. Each interior angle of a polygon can be calculated using the formula (n - 2) * 180° / n. In this case, we are given that the sum of the interior angles is 540 degrees.
So, we can set up the equation:
(n - 2) * 180° / n * n = 540°
Simplifying the equation:
(n - 2) * 180° = 540°
(n - 2) = 540° / 180°
(n - 2) = 3
Solving for n:
n = 3 + 2
n = 5
Now that we know the polygon has 5 sides, we can find the measure of x by substituting it back into the formula:
x = (5 - 2) * 180° / 5
x = 3 * 180° / 5
x = 540° / 5
x = 108°
In conclusion, the measure of x is 108 degrees, and each of the unknown angles in the polygon would also be 108 degrees since all angles in a regular polygon are equal.

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend. Matea recorded that the water level in one part of the river fell 1. 05 millimeters per year for 2. 48 years. This data will be compared to the average annual trend, which shows the water level rising 1. 8 mm/year. Which number represents the rate at which the water level fell? Which number should the rate be multiplied by to find the total variation in water level?.

Answers

The water level in one part of the river fell at a rate of 1.05 millimeters per year for a duration of 2.48 years. The average annual trend, however, indicates that the water level rises at a rate of 1.8 mm/year.

In Matea's recorded data, the rate at which the water level fell is given as 1.05 millimeters per year. This represents the change in water level over a period of one year. To calculate the total variation in water level, we need to multiply the rate of change by the duration of the observation. In this case, the observation lasted for 2.48 years.

To find the total variation, we multiply the rate of change (1.05 mm/year) by the duration (2.48 years):

Total variation = Rate of change * Duration

= 1.05 mm/year * 2.48 years

= 2.604 mm

Therefore, the water level in that particular part of the river fell by 2.604 millimeters over the course of 2.48 years.

It is important to note that the average annual trend, which indicates the water level rising at a rate of 1.8 mm/year, is not relevant to determining the rate at which the water level fell or calculating the total variation. The average annual trend is simply a reference point for comparison to assess whether the observed variation is consistent with the overall trend.

Using the following prices, calculate the unit price to determine how much it would cost for 7 granola bars and 9 bottles of water. $7. 14 for 6 granola bars $8. 72 for 8 bottles of water a. $18. 14 b. $18. 63 c. $21. 41 d. $31. 72 Please select the best answer from the choices provided A B C D.

Answers

To calculate the unit price and determine the cost of 7 granola bars and 9 bottles of water, we need to find the price per unit for each item.

The price for 6 granola bars is $7.14, which means the price per granola bar is $7.14/6. Similarly, the price for 8 bottles of water is $8.72, which gives us the price per bottle of water as $8.72/8. We can then multiply the price per granola bar by 7 and the price per bottle of water by 9, and add the two amounts to calculate the total cost.

To find the unit price of the granola bars, divide the total price ($7.14) by the quantity (6). This gives us the price per granola bar.

Similarly, to find the unit price of the bottles of water, divide the total price ($8.72) by the quantity (8). This gives us the price per bottle of water.

Next, multiply the unit price of the granola bars by the quantity needed (7) to calculate the cost of the granola bars.

Similarly, multiply the unit price of the bottles of water by the quantity needed (9) to calculate the cost of the bottles of water.

Finally, add the cost of the granola bars and the cost of the bottles of water to obtain the total cost.

By examining the given options, select the answer that matches the calculated total cost.

David hosts a podcast and he is curious how much his listeners like his show. He decides to poll the next 100 listeners who send him fan emails. They don't all respond, but 94 of the 97 listeners who responded said they "loved" his show. It is requested to determine which direction of bias is more likely in this scenario.

Bias is a tendency or inclination towards one side of an argument or viewpoint. In the given scenario, David decides to poll the next 100 listeners who send him fan emails, however, only 97 listeners responded. This could cause a bias towards those who love the show and have sent fan emails, and the opinion of those listeners who have not sent fan emails may not be taken into consideration.

The response rate is 97/100=0.97=97%.Therefore, the direction of bias in this scenario is "B. The results are probably an overestimate of the percentage of all listeners that love the show."This is because the response rate is only 97% which means that the opinions of 3% of the listeners who did not respond are not considered.

Additionally, there is a bias towards those who love the show and have sent fan emails, which does not represent the opinions of all the listeners.

Therefore, David should consider polling more listeners or find another way to gather feedback from his audience to get a more accurate representation of how much his listeners enjoy his show.

​$16000 is invested for 5 years with an APR of3 ​% and quarterly compounding

Answers

The accumulated value in 5 years of the  investment compounded quarterly is approximately: $18578.946

How to find the compound interest?

Compound interest differs from simple interest in that the interest received in one period will itself accrue in the next period. As a result, the amount in the account increases exponentially.

The future value of a compounding account depends on the number of compounding periods per year. Another factor is the annual interest rate. The higher the APR, the greater the cumulative value over time.

The formula for compound interest is:

FV = P(1 + (r/m))^(mt)

where:

FV is the future value of the investment.

P is the principal or initial amount invested.

r is the annual interest rate.

m is the number of compounding per year.

t is the time in years,

P = $16000

t = 5

m = 4

r = 3% = 0.03

Thus:

FV = 16000(1 + (0.03/4))^(4 * 5)

FV = $18578.946
