<h3>Answer: $26.62 </h3>

============================

Work Shown:

P = 20 is the amount deposited

r = 0.10 is the decimal form of the 10% interest rate

n = 1 means we compound 1 time per year (annually)

t = 3 is the number of years

Plug those four values into the compound interest formula below

A = P*(1+r/n)^(n*t)

A = 20*(1+0.1/1)^(1*3)

A = 20*(1+0.1)^(3)

A = 20*(1.1)^(3)

A = 20*1.331

A = 26.62

Answer: $26.6

Step-by-step explanation:

The formula for compound interest is stated as A = P*(1+r/n)^(n*t), where P is the Principal, r = rate, n is the number, and t is the time.

Given from the question,

P= 20

r = 10% = 10/100 = 0.01

n = 1 (compounded once per year)

t = 3 years

Slot the values into the formula:

A = 20 (1+0.1/1)^(1*3).....open the bracket

A = 20 (1+0.1)^3

A = 20 (1.1)^3

A = 20×1.33

A = 26.6

I hope this helps.

An expression represents the perimeter, in centimeters, of this triangle is 6q + 8r - 5s.

<u>Given the following data:</u>

  • a = (q + r) centimeters.
  • b = (5q - 10s) centimeters.
  • c = (5s + 7r) centimeters.

<h3>What is a triangle?</h3>

A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

<h3>How to calculate the perimeter of a triangle?</h3>

Mathematically, the perimeter of a triangle can be calculated by using this formula:

P = a + b + c

<u>Where:</u>

a, b, and c are length of sides.

Substituting the given parameters into the formula, we have;

P = q + r + 5q - 10s + 5s + 7r

P = 6q + 8r - 5s centimeters.

consider the gre scores for a random sample of 6 students out of a class of 25: name julia andrew jason cathy jessica robert sco
Thepotemich [5.8K]
Name  Score
Julia      650
Andrew 550
Jason    380
Cathy    720
Jessica 710
Robert   550

Point estimate for the mean score:
Sample mean = sum of all observations / number of observations

sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6 
sample mean = 593.33

The point estimate for the mean score is 593.33

Can someone answer this question please?

Part (a)

<h3>Answer:  0.2</h3>

----------------------------------

Work Shown

It costs $15 to rent a bike for 3 hours. We can write the following ratio below

15 dollars : 3 hours

To represent the connection of the two concepts (dollars connecting with hours)

We want the "15 dollars" to turn into "1 dollar". This is because the phrasing "per dollar" really means "per 1 dollar".

Divide both sides of the ratio by 15 to achieve this goal.

15 dollars : 3 hours

15/15 dollars : 3/15 hours

1 dollar : 1/5 hours

1 dollar : 0.2 hours

0.2 hours : 1 dollar

So we get 0.2 hours per dollar.

As a side note, 0.2 hours = 0.2*60 = 12 minutes.

========================================================

Part (b)

<h3>Answer:  3.38</h3>

----------------------------------

Work Shown

27 pages : 8 minutes

27/8 pages : 8/8 minutes

3.375 pages : 1 minute

3.38 pages : 1 minute

I'm dividing both parts of the original ratio by 8 to turn "8 minutes" into "1 minute" (due to the phrasing "per minute"). Don't forget to round to 2 decimal places.
