36-16=20

20•2=40

Jill started off with 40 comic books

Hope this helps!

Since Jill sold <u>half</u>, you would solve this by multiplying 36 by 2, which would be 64. A way to check this would be to divide your answer, or 62 by 2 (which symbolizes half).

Which inequality is true? Use the number line to help​
wlad13 [49]

Answer:

Option D.

Step-by-step explanation:

In order to resolve this problem, we are going to transform every fraction on a decimal number.

A) 2\frac{1}{2} is a mixed fraction. To get a proper fraction, we let the denominator as 2, and to get the numerator we multiply 2 by 2, and we add 1, as seen on the attached picture.

So:

2\frac{1}{2}=\frac{5}{2}

We divide 5 by 2 and we get 2,5.

So, the first option is not true, as 1.5 is smaller than 2,5.

B) We divide 1 by 2 and get 0,5. They are equal numbers, we can't say that 0,5 is bigger than 0,5.

C) -2.5 is smaller than -1,5 so this option is not true.

D) -3\frac{1}{2}=\frac{-7}{2}

We divide 7 by 2 and we get -3,5. In fact, -3,5 is bigger than -4.5, as there is a major distance from this negative number to cero.

A swimming pool measures 35 feet wide by long. What is the ratio of the length to the perimeter in simpiest form
guapka [62]
<h3><u>Question:</u></h3>

A swimming pool measures 35 feet wide by 50 feet long. What is the ratio of the length to the perimeter

<h3><u>Answer:</u></h3>

The ratio of length to perimeter of pool is 5 : 17

<h3><u>Solution:</u></h3>

Given that, swimming pool measures 35 feet wide by 50 feet long

Therefore,

Length = 50 feet

Width = 35 feet

Swimming pool is usually of rectangular shape

<em><u>The perimeter of rectangle is given as:</u></em>

Perimeter = 2(length + width)

Perimeter = 2(50 + 35)

Perimeter = 2(85) = 170

Thus perimeter of pool is 170 feet

<em><u>Ratio of length to perimeter:</u></em>

\frac{Length}{Perimeter } = \frac{50}{170}\\\\\frac{Length}{Perimeter } = \frac{5}{17}

Thus ratio of length to perimeter of pool is 5 : 17
