Answer:
Step-by-step explanation:
You have a circle with radius r = 3 ft and a 3-by-12 rectangle.
Area of circle = πr² = 9π ft²
Area of rectangle = 3 × 12 = 36 ft²
Total area = 36 + 9π ≈ 64.3 ft²
Perimeter of circle = 2πr = 6π ft
Perimeter of rectangular projections = 18 ft
Total perimeter = 6π +18 ≈ 36.8 ft
If your rate of travel is 25 mph, it will take you 25 times an unknown amount of hours, x, to drive 175 miles.
175 = 25x
Divide both sides by 25.
175/25 = 25x/25
7 = x
Answer:
It will take you 7 hours to drive 175 miles at a speed of 25 mph.

Answer:
$17.07
Step-by-step explanation:
Step 1: Find the percent of the price
Convert 7% to fraction
Multiply
Multiply the factors
Divide
Step 2: Add the percent off to the original price
Therefore, the total cost including tax in the nearest cent is 17.07 dollars
Answer:
100/3 or 33.33
Step-by-step explanation: If the perimeter of the whole figure is 220, we can use that number to solve the equations on the trapezoid.
2(2x-3) + 2(4) + 2(4x+1)
4x - 6 + 8 + 8x + 2
12x + 2
Now we have to set the equation equal to the perimeter to find the value of x
12x + 2 = 220
12x = 218
x = 109/6
Since we are only finding the length of PS, we will plug x into its equation (2x - 3).
2(109/6) - 3
109/3 - 3
109/3 - 9/3
100/3
