Answer:
a = 66
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary.
a = 180° -114°
a = 66°
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.
Answer:
105
Step-by-step explanation:
You need to find the unit rate which is 10.50$. Then you would multiply it by 10.
Answer:
Step-by-step explanation:
<u>Multiples of 16:</u>
<u>Multiples of 20:</u>
<u>Here are the options verified:</u>
- A. 4 and 20. Incorrect. It takes a while to get to 80 by 4's.
- B. 8 and 10. Incorrect. Same thing goes with A, but with 8's.
- C. 16 and 20. Correct.
- D. 12 and 40. Incorrect. 12 is not a multiple of 80.
Option C is your answer.
