A) the base is a square to find its area you can use the formula:
a =  {s}^{2}  \\
a being the area and s one of the sides

now just use s= 55ft
a =  {55}^{2}  = 3025
The area of the base is 3025 ft^2

b) the volume of the pyramid is:
v =  \frac{b \times h}{3}
v being the volume, b the area of the base and h the height of the pyramid
use b=3025 and h=460
v =  \frac{3025\times 460}{3}  = 463833.3
the volume of the pyramid is 463833.3 ft^3

A debt of $9,388.81 is repaid by payments of $1,160.62 in 4 months, $1,178.29 in 13 months, and a final payment in 23 months. If
____ [38]

Answer:

after 4 months $8352.96

AFTER 13 MONTH $7426.507

AFTER 23 MONTH A = 7675.69

Step-by-step explanation:

Given data:

P = $9388.81

Compound interest cab be determined as

A = P( 1+ r/n)^(nt)

after 4 months

A = 9388.81 ( 1+ \frac{4}{100})^{2\times \frac{4}{12}}

A = 9513.58

But he has to pay $1160.62 after 4 month so remaining amount is

P = 9513.58 - 1160.62 = $8352.96

AFTER 13 MONTH, so total time is 9 month

A = 8352.96 ( 1+ \frac{4}{100})^{2\times \frac{9}{12}}

A = 8604.79

But he has to pay $1178.29 after 13 month so remaining amount is

P = 8604.79 - 1178.28 = $7426.507

AFTER 23 MONTH so total time is 10 month

A = 7426.50 ( 1+ \frac{4}{100})^{2\times \frac{10}{12}}

A = 7675.69
