ANSWER: $84

EXPLANATION:

We need to know the surface area of the room with the specified dimensions.

A = 2(wl + hl + hw)

w = 12
h = 8
l = 16

A = 2( (12 * 16) + (8 * 16) + (12 * 8) )

A = 2(192 + 128 + 96)

A = 2(416)

A = 832 square feet


832 / 150 = 5.546666666666667

(Round that up to the next whole number)

You need 6 gallons, or 6(14) dollars

Apply the distributive property to factor out the greatest common factor.<br> 56<br> +<br> 32<br> =
valentina_108 [34]

Answer:

8 * (7 + 4)

See process below

Step-by-step explanation:

We start by writing each number in PRIME factor form:

56 = 2 * 2 * 2 * 7

32 = 2 * 2 * 2 * 2 * 2

Notice that the factors that are common to BOTH numbers are 2 * 2 * 2 (the product of three factors of 2).Therefore we see that the greatest common factor for the given numbers is : 2 * 2 * 2 = 8

Using this, we can write the two numbers as the product of this common factor (8) times the factors that are left on each:

56 = 8 * 7

32 = 8 * 2 * 2 = 8 * 4

We can then use distributive property to "extract" that common factor (8) from the given addition as shown below:

56 + 32

8 * 7 + 8 * 4

8 * (7 + 4)

8 * (11)

44)

equation-     T= 12.17+0.75v

105.75= 12.17 + .75v

-12.17    -12.17

PLEASE HELP WITH THE PROBLEM ON THE ATTACHED FILE
prisoha [69]

Answer:

6 : 1

Step-by-step explanation:

b - 3a / 9 = a /3

Cross multiply

3(b - 3a) = 9a

Expand

3b - 9a = 9a

Add 9a to both sides

3b = 9a + 9a

3b = 18a

Divide both sides by 3

b = 6a

Ratio of a : b

6 : 1
