PLZZZZ HELPPPPPP THIS IS TIMEDDDD!!!! *look at picture*
Kazeer [188]

Answer:

Height of the building = 50.8 ft

Step-by-step explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.

\frac{x}{28}=\frac{5.8}{3.2}

x = \frac{5.8\times 28}{3.2}

x = 50.75

x ≈ 50.8 ft

$35,125 loan, a feat which took ten years of quarterly payments. The loan had an interest rate of 7.44%, compounded quarterly. I
Darya [45]
First find the amount of each payment:
35,125 = P(\frac{(1+i)^{40} -1}{i (1+i)^{40}}) , i = \frac{.0744}{4}  \\  \\ P = 1252.70

The total cost will be 40 payments plus service charges.
40*1252.70 + 5180.70 = 55,288.90

The percentage is the service charge divided by total cost:
X = \frac{5180.70}{ 55,288.90} = .0937 = 9.37\%
