A person invested \$150$150 in an account growing at a rate allowing the money to double every 13 years. How much money would be in the account after 22 years, to the nearest dollar?

Answers

Answer:

Amount after 22 year = $484.80 (Approx.)

Step-by-step explanation:

Given:

Amount deposit in bank = $150

Double in year = 13 year

Find:

Amount after 22 year

Computation:

A = P[1+r]ⁿ

Amount after 13 year = 2 x 150

Amount after 13 year = $300

300 = 150[1+r]¹³

2 = [1+r]¹³

Rate of interest = 5.477%

Amount after 22 year

A = P[1+r]ⁿ

Amount after 22 year = 150[1+5.477%]²²

Amount after 22 year = $484.80 (Approx.)

How to calculate the area of a square

Answers

Answer:

a × a × a ×a

Step-by-step explanation:

Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

Answers

Looking at the triangle we see the angles:

58, x

We also see a right angle, therefore you now have:

90, 58, 0

All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.

90 + 58 = 148

180 - 148 = 32

Therefore, x = 32 or C

Sarah needs 3 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabric costs $1.20. How much will the fabric cost? [1 ft = 0.305 m]

Answers

Answer:

The 3 feet fabric will cost $ 1.09728 almost $ 1.10

Step-by-step explanation:

First we will find out how many meters 3 feet will be.

1 feet = 0.3048 meters

She needs 3 feet of fabric

3 *1 feet = 3* 0.3048  ( multiplying both sides by 3)

3 feet = 0.9144 meters

Using the unitary method we will find the cost of 3 feet of fabric

1 meter costs $ 1.20

0.9144 *1 meter costs $ 1.20 * 0.9144  ( multiplying both sides by 0.9144)

0.9144  meter = $ 1.09728

The 3 feet fabric will cost $ 1.09728 almost $ 1.10

Answer: 1.10
