The dog house consists of two geometric objects, triangular prism and rectangular prism.

First, find the surface area of triangular prism
The triangular prism consists of
base of triangle (b) = 3 ft
height of triangle (h) = 2.5 ft
height of prism or length of rectangle (l) = 4 ft
side of triangle or width of rectangle (w) = 2.5 ft

Now, calculate the area
area of tp = area of two triangle + area of 2 rectangle
area of tp = (2 × 1/2 × b × h) + (2 × l × w)
area of tp = (2 × 1/2 × 3 × 2) + (2 × 4 × 2.5)
area of tp = 6 + 20
area of tp = 26 ft²

Second, find the surface area of rectangular prism
The rectangular prisms consists of
length (l) = 3 ft
width (w) = 4 ft
height (h) = 2 ft

Now, calculate the area
area of rp = area of back and front rectangle + area of left and right rectangle
area of rp = (2 × l × h) + (2 × w × h)
area of rp = (2 × 3 × 2) + (2 × 4 × 2)
area of rp = 12 + 16
area of rp = 28 ft²

Third, add both of the area
area = area of tp + area of rp
area = 26 + 28
area = 54 ft²

The area of the dog house is 54 ft
²

Determine the amount of an
Alisiya [41]

Answer:

$1435.18

Step-by-step explanation:

determine the amount of an investment if 700$ is invested at an interest rate of 8% compounded monthly for 9 years

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

A(9) = 700(1+0.08/12)^(12*9)

A(9) = 700(1+0.00667)^(108)

A(9) = 700(2.05026

A(9) = $1435.18

When you last balanced your checkbook, you had $463.76. You then wrote checks for $12.56, $52.11 and $26.03. You deposited $101.
Sonja [21]

Add your checks: 12.56 + 52.11 + 26.03 = 90.70

Subtract that from starting balance:

463.76 - 90.70 = 373.06

Add the deposits:

373.06 + 101.32 + 10.98 = 485.36

Your balance is correct.

Subtract your balance from the bank balance:

511.39 - 485.36 = 26.03

The difference is the amount of one of the checks you wrote, which means that check has not been cashed yet.

You did not do anything wrong.
