Hi there.
The answer is definitely "D" because on the graph it shows there are only 29 students that did the test.
in right angle traingle two angle are equal
so.x=y
in triangle
x+y+90=180(sum of interior angle of triangle)
2x=180-90
x=90/3=45°
The monthly interest rate is 0.75%

Answer:
Rock CD's=21
Country CD's=12
Soundtrack CD's=3
Step-by-step explanation:
let
r= rock CD's
c = country CD's
s = soundtrack CD's
Total CD's=r + c + s =39
2c=r
c/4=s
2c+c+c/4=39
8c+4c+c=156
13c=156
c=12
Substitute c=12 into 2c=r
2c=r
3(12)=r
24=r
r=24
Substitute c=12 into c/4=s
c/4=s
12/4=s
3=s
s=3
Therefore, she has
c=12
s=3
r=24
before she borrowed you 3 rock CD's
Sha has
r=21
s=3
c=12
after you borrowed 3 rock CD's
