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.)

Answers

Answer:

a.) 92% is the correct answer.

Step-by-step explanation:

To get the occupancy rate, you will need to divide the number of room sold to the number of rooms available and multiply that number by 100%, which is (580*100%)/632=91.77% ~ 92%

Hannah buys ⅔ pound of roast beef. She uses ¼ pound to make a sandwich for lunch. How much roast beef does she have left?

Answers


Answer:
5/12

Explanation:
With unlike denominators find the Least Common Denominator (LCD)

LCD = 12
3x4=12

Multiplying numerators and denominators to get the LCD in all fraction denominators
=2×4/3×4 − 1×3/4×3

Then rewriting the equation with the equivalent fractions
=8/12 − 3/12

With like denominators we can operate on just the numerators
=(8−3)/12
=5/12

What is an equation of the line that passes through the points (7, 6) and (-2, -3)?

Answers

Answer:

Remember the formula for the slope which is change in y over change in x

therefore:      (7+2)/(6+3)= 1         slope=1

formula for a line is y=mx+b

plug in your slope and one of the given coordinates to find the y-intercept:

y=1x+b

7=1(6)+b

7=6+b

1=b

so the equation for the line would be y=x+1

Students did push-ups for a fitness test. Their goal was 20 push-ups. For each student,
determine what percentage of the goal they achieved.
1. Elena did 16 push-ups.
2. Jada did 42 push-ups.
3. Lin did 13 push-ups.
4. Andre did 21 push-ups.

Answers

Answer:

1- 80%

2- 210%

3- 65%

4- 105%

Step-by-step explanation:

The percentage of the goal achieved by them:

1). 80%

2). 210%

3). 65%

4). 105%

Find the percentage

1). Goal of push-ups = 20

No. of push-ups done by Elena = 16

Percentage = 16/20 × 100

= 80%

2). Goal of push-ups = 20

No. of push-ups done by Jada = 42

Percentage = 42/20 × 100

= 210%

3). Goal of push-ups = 20

No. of push-ups done by Lin = 13

Percentage = 13/20 × 100

= 65%

4). Goal of push-ups = 20

No. of push-ups done by Andre = 21

Percentage = 21/20 × 100

= 105%

Thus, the above answers are correct.
