Answer:

Distributive property

Step-by-step explanation:

Step-by-step explanation:

let the width be x

length= 10x+ 15

perimeter = 2(l+b)

= 2(10x+ 15 + x)

2(11x+15)

=22x+30

Answer:

Look at my explanation

Step-by-step explanation:

The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.

2πr = 22π

divide both sides by 2

πr = 11π

divide both sides by π

you get r = 11

So your radius is 11.

To find the area, you must do πr^2 ("^2" means squared)

if you substitute 11 for r you get

11π^2

you can do 11 squared first

11^2 = 121

the area of the circle = 121π

Keep in mind that they said to use 3.14 for π

so you can do 121 x 3.14

Final Answer: 379.94

Answer: 75%

Step-by-step explanation:

First: work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100

Decrease =240- 60

Decrease = 180

180 /240=0.75 * 100 = 75%

The percent of decrease = 75%

Step-by-step explanation:

Use savings annuity formula

Substitute A(25) = $550,000 , R= 0.03 and N=12 simplify and solve for D.

You have earned 292589 dollars from compound interest.

Compound interest is calculated from both the initial principle and the previous accumulated interest.

According to the given question you invest, every month, in an annuity that pays 3% interest.So r = 3.

After 25 years, you have 550,000 dollars so amount (A) = 550,000.

We know, Interest = Amount - Principle.

A = P(1 + r/100)ⁿ, where n represents time in years.

Given n = 25.

The interest is compounded monthly so the formula will be

A = P[1 + (r/12)/100]¹²ⁿ.

555000 = P[ 1 + 3/1200]¹²ˣ²⁵.

555000 = P[ 1203/1200]³⁰⁰.

555000 = P(1.0025)³⁰⁰.

555000 = 2.115P

P = 262411.

CI = ( 555000 - 262411) dollars.

CI = 292589 dollars.

then find the area of the side squares 10x4 which is 40 and then find the front and back squares which is 6x10 which is 60. then add them all up 24+24+40+40+60+60=248

Answer:

20.95$

Step-by-step explanation:

To find the total price we need to find 4.75% of the 20 and to do that we need  to multply 20 with 4.75 and divide it by 100

20 × 4.75 ÷ 100 = 0.95

20$ + 0.95$ = 20.95$

Answer:

AB = 184.4 yards

Step-by-step explanation:

The description here gives a triangle with two angles and a side. Let the distance between A and B be represented by d. Thus applying the Sine rule, we have;

[tex]\frac{a}{Sin A}[/tex] = [tex]\frac{b}{Sin B}[/tex]

[tex]\frac{200}{Sin 87}[/tex] = [tex]\frac{d}{Sin 67}[/tex]

d = [tex]\frac{200*Sin 67}{Sin 87}[/tex]

  = [tex]\frac{200*0.9205}{0.99863}[/tex]

d = 184.3526

Thus, the distance between points A and B is 184.4 yards

Answer:

Amount of each payment = $15 each month

Step-by-step explanation:

Given:

Amount borrow = $600

Simple rate = 5% = 0.05

Number of year = 4 year

Payment method = monthly payment

Find:

Amount of each payment

Computation:

Total amount after 4 year = P + PRT

Total amount after 4 year = 600 + (600)(4)(0.05)

Total amount after 4 year = 600 + 120

Total amount after 4 year = $720

Number of total month = 4 x 12

Number of total month = 48

Amount of each payment = Total amount after 4 year / Number of total month

Amount of each payment = $720 / 48

Amount of each payment = $15 each month
