Step-by-step explanation:
You do 0.25 x 50 = 12.5 take 12.5 away from 50 you get 37.5 so id say 38 is the answer
7. C
8.A. sqrt(144)
^^^^^^^^^^^^^^^^^^
Hi, thank you for posting your question here at Brainly.
All you have to do to acquire the equation is to substitute the variables to the formula for A and simplify. Since A = 1/2*b*h and h = bsin(C), then A can be in terms of one variable only, which is b.
A = 1/2*b*bsin(c)
A = 1/2*b^2*sin(C)
Im pretty sure she has 6 quarters and 12 nickels since it it twice as much.
$0.25 x 6 =150
$0.5 x 12 =60
total = 210
