Angle CGA supplementary angles add up to 180°
Answer: The rate of change in the value of the guitar is modeled by 0.95, which represents a decrease of 5% per year.
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential decay function:
A = P (1 - r) t
Where:
p = original price
r = decrease rate (decimal form)
t= years
A = price after t years
Replacing with the values given:
A(t)=145(0.95)t.
Where
0.95 = 1-r
0.95-1 = r
-0.05 =-r
0.05 =r
Converting to percentage form:
0.05 x 100 = 5%

There are two correct answers. Numbers 3 4 are both correct. The sum of all angles in a triangle must add up to 180°. The two given where are 40° and 52°. If you subtract these from 180°, the remaining angle would be 88°. Choices 3 and4 both give two possible angles.
Answer:
11°<x°<58°
Step-by-step explanation:
first find out how much x can be by using 180 degrees.
(5x+3)°+(5x+3)°+58=180°
(10x+6)°+58°=180°
10x°+64°=180°
10x°=116°
x=11.6°
hope that helps!
Answer:
first piece = 1.88in
second piece= 3.76in
third piece = 26.32in
32 = f + s + t
1st piece = f
2nd piece = s
3rd piece = t
what we know:
s = 2f
t = 2(7f)
32 = f + 2f + 2(7f)
32 = 3f +14f
32 = 17f
f = 1.88
now sub in:
f = 1.88
s = 3.76
t = 26.32
when you add these together you get 31.96, when you round up you get 32 which is the original piece of steel.
