Well first it would be 49x3 and that would equal the area so the area is 147. Next you would want to divide that by 4 because there is four sides of the mural, so 147 divided into 4 equals 36.75 square centimeters per side of the mural. The nearest tenth I believe would be 3.675.


So answer: 3.675 but I’m not sure so don’t get mad at me if I’m wrong lol

Select a real-world problem for the equation 18w = 108. Then solve the problem. A If total rainfall for last month was 108 inche
Ket [755]

The problem is multiplying w by 18 to get a total of 108.

The answer would be :

D If one full glass holds 18 ounces of water, how many full glasses will hold 108 ounces?

To solve for the number of cups divide both sides of the equation by 18:

18w = 108

W= 108 / 18

W = 6

It would take 6 18 ounce glasses to equal 108 total ounces.

Simplify: (2x – 3)2<br><br> 4x2 + 9<br><br><br> 4x2 – 12x + 9<br><br> 4x2 – 12x + 6<br><br> 4x2 – 6
Alexxandr [17]

Answer:

4x^2-12x+9

Step-by-step explanation:

we have

(2x-3)^2

we know that

(a-b)^2=a^2-2ab+b^2

In this problem

a=2x\\b=3

substitute in the formula

(2x-3)^2=(2x)^2-2(2x)(3)+(3)^2

(2x-3)^2=4x^2-12x+9

Mrs. Galicia is creating a bunny farm. The farm starts with 820 bunnies and is growing at a rate of 20.75% per month. How many m
drek231 [11]

The number of months it would take the bunny farm to triple in size is 5.3 months.

<h3>When would the bunny farm be triple its size?</h3>

The formula that can be used to determine the number of months it would take Mrs. Galicia's bunnies to triple in size is:

Number of years =  (In FV / PV) / r

  • FV = future population of the bunnies
  • PV = present population of the bunnies
  • r = rate of growth
  • FV / PV = 3

IN(3) / 0.2075 = 5.3 months

How do I solve -0.4r=16?
Leviafan [203]

Answer:

r = -40

Step-by-step explanation:

1. Move constants to the other side of the equation

r = 16/-.04

2. Simplify (by calculator)

You can use a calculator and plug in 16/-.04

r = -40

2. Simplify (by fraction)

You can turn -.4 into a fraction.

-.04 = - 4/10

r = 16/-(4/10)

r = 16*10/-4

r = -40
