The answer is C, because those are the points that cross the x-axis.
Answer:
8c= $225
Step-by-step explanation:
Number of shirts ×cost of each shirt= total cost
Since she bought 8 shirts and the cost of each is c,
8c= $225
To solve for c, divide both sides of the equation by 8:
c= $225 ÷8
c= $28.125
< y and 72 degrees are supplementary angles
so y = 180 - 72 = 108 degrees.
Answer:
200 miles
Explanation:
Here map to actual to scale: 1 inch = 50 miles
- On map distance: 4 inches
To find actual distance, simply multiply map distance by scale factor
Actual Distance : 4 × 50 = 200 miles
Answer:
The rate of change of each circular surface of the dough is approximately 150.796 in.²/minute
Step-by-step explanation:
The given parameters are;
When the radius of the dough, r = 12 inches, the radius is increasing at 2 inches per minute
Therefore, we have;
dr/dt = 2 in./min
The area of the circular surface of the dough, A = π·r²
The rate of change of each (top or bottom) circular surface area of the dough dA/dt is given as follows;
dA/dt = d(π·r²)/dt = π·2·r·dr/dt
Where;
r = 12 in.
dr/dt = 2 in./min
Substituting, we have;
dA/dt = π·2·r·dr/dt = π × 2 × 12 in. × 2 in./min ≈ 150.796 in.²/minute.
The rate of change of each circular surface of the dough = dA/dt ≈ 150.796 in.²/minute.
