Answer:

108

Step-by-step explanation:

<u>find the volume of the cooler</u>:

V=πr²h

π×6²×16= 1809.56

<u>find the volume of the cup</u>:

V=πr²(h/3)

π×2²×(4/3)= 16.76

<u>divide the volume:</u>

1809.56/16.76= 107.969

Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.

If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)
Sphinxa [80]

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56
