$750 + s x 4% = $2,500 | - $750
s x 4% = $1,750 | : 4%
s = $43.750
Answer:
x = 2.8
y = 2
Step-by-step explanation:
Reference angle = 45°
Opposite = 2
Hypotenuse = x
Adjacent = y
✔️To find x, apply the trigonometric function SOH:
Sin 45 = Opp/Hyp
Sin 45 = 2/x
x*Sin 45 = 2
x = 2/Sin 45
x = 2.82842712 ≈ 2.8 (nearest tenth)
✔️To find y, apply the trigonometric function TOA:
Tan 45 = Opp/Adj
Tan 45 = 2/y
y*Tan 45 = 2
y = 2/Tan 45
y = 2
Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h
R = 27 cm
H = 37 cm
Take away the Pi seeing as you want to keep it in terms of Pi
2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B
Answer:
614.25
Step-by-step explanation:
The amount of interest is computed using ...
... I = Prt . . . . . where P is the principal amount, r is the annual interest rate, and t is the number of years.
Here, the interest is ...
... I = 520×0.075×(2 5/12) = 39×29/12 = 94.25
The total amount due, interest plus principal, is ...
... 94.25 + 520 = 614.25
Answer:
r = -2
Step-by-step explanation:
2+2 = 4
7-3 = 4
4/4 = 1
m = 1
