Assume the monthly interest rate is 1/12 of the annual interest rate . you maintain an average balance of $450 on your credit ca
masya89 [10]

Answer:

The monthly interest payment would be $ 9

Step-by-step explanation:

Given,

The average balance of the credit card = $ 450,

Annual rate of interest = 24%,

∵ Monthly interest rate is 1/12 of the annual interest rate,

Thus, the monthly interest rate = \frac{1}{12}\text{ of }24\%

=2\%

Hence, the monthly interest payment = 2% of credit card balance

= 2% of 450

=\frac{2\times 450}{100}

=\frac{90}{10}

= $ 9

Mr. Gonzalez built two identical flower beds in his yard with the dimensions shown. A prism has a length of 6 feet, height of 2
Lady bird [3.3K]

Answer:

For the 2 the identical flower beds he will require 44 × 2 = 88 ft² of paints to paint the sides of the beds.

Step-by-step explanation:

The prisms are 2 identical flower beds . The dimensions are the same which have a length of 6 ft , height of 2 ft and width of 5 ft. He wants to paints the side of the beds which is the lateral area of the prisms.

Lateral surface area of a rectangular prism is adding the area of the lateral faces of the prism.

Lateral surface area = PH

P = perimeter of the side

H = height

perimeter = (2L + 2W)

where

L = length

W = width

L = 6 ft

W = 5 ft

perimeter = (2L + 2W)

perimeter = (2 × 6 + 2 × 5)

perimeter = (12 + 10)

perimeter = 22 ft

Lateral area = 22 × 2

Lateral area = 44 ft²

For the 2 the identical flower beds he will require 44 × 2 = 88 ft² of paints to paint the sides of the beds.

1) What is the solution to x - 5 = 27?
Phoenix [80]
X - 5 = 27

Isolate the x, add 5 to both sides (because of equal sign)

x - 5 = 27
x - 5 (+5) = 27 (+5)
x = 27 + 5
x = 32

x = 32 is your answer

hope this helps
