Answer:

I am guessing about 150 - 200 students did not buy a yearbook.

Step-by-step explanation:

First let's assume that there are 1,000 or so students in the school. 856 would be a little over 4/5 of 1,000 just as 8 would be 4/5 of 10.

If two supplementaryangles are in the ratio 2:3, find the angles.

kramer

The angles are 72 degrees and 108 degrees.

Explanation:

Angle 1 : Angle 2 = 2 : 3
Angle 1 = 2k
Angle 2 = 3k

Angle 1 + Angle 2 = 180 (supplementary angles)
2k + 3k = 180
5k = 180
k = 36

Angle 1 = 2k = 2 x 36 = 72 degrees
Angle 2 = 3k = 3 x 36 = 108 degrees

Andrei [34K]

The domain of the function is all the values from which the functio can be mapped: here it's between 0 and <span>76,867 -depending on how many people come

</span> $0 \leq x\geq 76867$

The range is all the values that the function can have.So here it's from 0, when noone is coming, to 76867*161=12377036

$0 \leq y\geq 12377036$
