88= 2l + 2w
l=3w
88=2(3w)+2w
88= 6w+2w
88=8w
w=11
l=3(11)
l=33
width= 11
length= 33

2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).
castortr0y [4]

Let

F--------> represent the force

m--------> represent the mass

a-------> represent the acceleration

we know that

The formula that relates three quantities: Force (F), mass (m), and acceleration (a) is equal to

F=ma

<u>Part a)</u> Solve this equation for a

F=ma

Divide both sides by the mass

a=\frac{F}{m}

therefore

<u>the answer part a) is equal to</u>

a=\frac{F}{m}

<u>Part b) </u>Let the force be 25 units and the mass be m = 10 units. What is the acceleration, a?

we know that

the formula of acceleration is equal to

a=\frac{F}{m}

in this problem

we have

F=25\\m=10

Substitute the values n the formula

a=\frac{25}{10}

a=2.5

therefore

<u>the answer part b( is equal to</u>

a=2.5

<u>Part c)</u> Let the force be F = 25 units and the acceleration be a = 5 units. What is the mass, m?

we know that

F=ma

Solve for m

Divide both sides by the acceleration

m=\frac{F}{a}

in this problem

we have

F=25\\a=5

Substitute the values n the formula

m=\frac{25}{5}

m=5

therefore

<u>the answer Part c) is </u>

m=5

15 feet out of 36 feet
mars1129 [50]

Answer:

15/36 or 0.41666666666 or 41.6 percent

Step-by-step explanation:

Not sure if you're looking for the fraction or something else but to find the fraction, divide 15 by 36.

15/36

The decimal you get is 0.41666666666.

This converts to a percentage of 41.6 percent. (multiply by 100 to get percent when dealing with decimals)

So 15 feet is 41.6 percent of 36.

Hope this helped.

What is 1/144 as an expression using a negative exponent
MrRissso [65]

ANSWER

{12}^{ - 2}

EXPLANATION

The given expression is

\frac{1}{144}

This is the same as:

\frac{1}{12 \times 12}

In index notation, we write this as

\frac{1}{ {12}^{2} }

To write this as a negative index, we use the property:

\frac{1}{ {a}^{m} }  =  {a}^{- m}

This implies that;

\frac{1}{ {12}^{2} }  =  {12}^{ - 2}
