Answer:
Step-by-step explanation:
Adapt the compound amount formula to this situation:
A = P(1 + r)^t becomes A = d(1 + p/100)^1, or just A = d(1 + p/100)
Since supplementary angles equal 180. (2x+15) = 45, which can be found by subtracting 135 from 180. This means that x = 15. And since angle 1 corresponds to the previous angle, we can deduce that angle 1 = 45.
Answer:
d ≈ 29.99 cm
Step-by-step explanation:
The volume of a cylinder can be calculated by the formula V = pi * r^2 * h.
V = pi * r^2 * h
We know the volume and the height, so we can use the formula to determine the radius, which can be used to determine the diameter.
4239 = pi * r^2 * 6 (I will add the units later | Divide both sides by 6)
706.5 = pi * r^2 (Divide both sides by pi)
706.5/pi = r^2 (Take the square root of both sides)
sqrt (706.5/pi) = r (r is the radius)
r ≈ 14.99619733762023
The diameter will be double this value.
d ≈ 29.99239467524046
d ≈ 29.99 cm
"The square of x" means x^2, so we can eliminate options A and D.
"product of 8 and x" means that 8 and x are multiplied together (like 8x)
If x^2 is increased by 8x, we are adding x^2 and 8x together.

Answer:
she would save $10
Step-by-step explanation:
shirt = $25
coupon = 40%
25 * .40 = 10 ---> represents 40% of 25
she would save $10
extra:
25-10 = 15 ---> she would pay $15
