Answer: 58 minutes
55*4=220
62+57+43=162
220-162=58
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

Let:
T1 = temperature at 6:00 AM
T2 = temperature during the day
T3 = Temperature by early evening
The temperature at 6:00 AM was -8. so:

The temperature rise 5 during the day:

and then fell 3 by early evening, therefore:
Answer:
D
Step-by-step explanation:
4/3 (3.14) r^3 is the equation, so since the radius is 4
It's 4/3x(pi)64
256/3x(pi)
