Answer:
x = 56.25
Step-by-step explanation:
The sides of the rectangle are in the ratio 3:4, so those together with the diagonal of the rectangle make a 3-4-5 right triangle. The sum of these adjacent-side ratio units is 3+4 = 7, so the perimeter in ratio units is 2×7 = 14. The actual perimeter is 42 inches, so each ratio unit must stand for ...
(42 in)/(14 units) = 3 in/unit
The diagonal of the rectangle is the diameter of the circle. Its length is 5 units, or ...
(5 units)×(3 in/unit) = 15 inches.
Then the radius is half the diameter, or 7.5 inches.
The area of a circle is given by ...
A = πr² = π(7.5 in)² = 56.25π in²
The value of x is 56.25.

Answer:
3
Step-by-step explanation:
10.50 x 3 = 31.5
15 x 13 = 195
195 + 31.5 = 226.50
Answer:
y = $100 + $25x
Step-by-step explanation:
y is the total cost
x is the number of months
The sign up fee is $100.
Each month would cost an additional $25 per month.
The total cost then would be the sign up fee plus the $25 for each month. Since we do not know the number of months, we will assign x.
So the equation would be:
y = $100 + $25x
Approximately 9 meters are in 10 yards, (as there is approximately 1 meter in a yard, .9144 to be exact.)
