Above is the layout of a running track and inside the track is a field. If it costs $5.00 /m2 for soil for the field,
describe how you would determine the total cost to cover the field with soil. help!
Answers
Answer:
We can think in the area as:
A rectangle of 100m by 64m
And two half circles (o a whole circle if we combine them) of diameter = 64m
Then we need to calculate the area of these two figures and then sum them.
The area of a rectangle of width W and length L is:
A = A*L
then the area of the rectangle will be:
A1 = 100m*64m = 6400m^2
The area of a circle of diameter d is:
A = pi*(d/2)^2
in this case, d = 64m
pi = 3.14
Then:
A2 = 3.14*(64m/2)^2 = 3215.35m^2
The total area of the field is:
A = A1 + A2 = 6400m^2 + 3215.35m^2 = 9615.36 m^2
Now, we know that the cost per square meter is $5.00
Then the total cost will be:
Cost = A*$5.00/m^2 = 9615.36 m^2*$5.00/m^2 = $35215.36

A house on the market was valued at 238,000. After several years, the value decreased by 15% . By how much did the house's value decrease in dollars? What is the current value of the house? Decrease in value and current house value
Answers
Answer:
The current house value is $202,300 and the house's decrease in dollars is $35,700.
Step-by-step explanation:
The house on the market was valued at $238,000. After years, it decreased by 15%. So, let's calculate 15% of the total amount.
238,000 x 0.15 = $35,700
Therefore, the house's decrease in dollars is $35,700
To calculate the current value of the house, we need to subtract the value decrease from the original amount.
238,000 - 35,700 = $202,300
Therefore, the current house value is $202,300.
Hope this helps! :)

Step 1: Define equation
-3(x - 1) = x - 5
Step 2: Solve for x
Distribute -3: -3x + 3 = x - 5Add 3x to both sides: 3 = 4x - 5Add 5 to both sides: 8 = 4xDivide 4 on both sides: 2 = xRewrite: x = 2Step 3: Check
Plug in x to verify it's a solution.
Substitute: -3(2 - 1) = 2 - 5Subtract: -3(1) = -3Multiply: -3 = -3Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.

the formula for calculating the perimeter of a circle (the circumference C) is:
2π * r
And the area is:
π * r²
r is the radius.
Radius is the half of the diameter. The diameter here is equal to two square. One square is 5 of side.
The diameter is 10 and the radius is 5
C = 2 * 3.14 * 5 = 31.4A = 3.14 * 5² = 3.14 * 25 = 78.5It is the same for the other circle

Answers
Answer:
R = 16:25
Step-by-step explanation:
Given that,
Johan mixes 2 2/3 pints of blue paint and 4 1/6 pints of yellow paint.
We need to find the ratio of blue paint to yellow paint. It can be calculated as follows :
[tex]R=\dfrac{\text{blue paint}}{\text{yellow paint}}\\\\=\dfrac{2\dfrac{2}{3}}{4\dfrac{1}{6}}\\\\=\dfrac{\dfrac{8}{3}}{\dfrac{25}{6}}\\\\=\dfrac{8}{3}\times \dfrac{6}{25}\\\\=\dfrac{16}{25}[/tex]
So, the required ratio is 16:25.
