Answer:
Step-by-step explanation:
Total Students in Class = 25+ 15=40
Probability= (Number of Girls in Class) ÷ (Total students in Class)
Probability of girl= 15 ÷ 40 = 0.375
Answer: 44.4
Step-by-step explanation:
We are asked to find angle V, so we are going to use our trig ratios to explain this one. They have given us the side opposite of angle v and the hypotunse. angle v. so we are going to be using sine. . SOHCAHTOA.
First, let use the ratio for sine
which equal to 
then we are to take the arcsine or the sine inverse because we are trying to the angle measure not side length. (
(7/10) which gives us 44.4
I think it is the last one because the two top line at the top must be the same length
<span>1/2 x +(-7)- 2 1/4 x -(-2)
Turn the 2 1/4 into a mixed number:
1/2x + (-7) - 9/4x + 2
Multiply 1/2x by 2/2:
2/4x + (-7) - 9/4x +2
Add common terms:
-7/4x - 5
Turn -7/4x into a mixed number:
-1 3/4x -5
So your answer is
A.) -1 3/4x - 5
