irina1246 [14]

Answer:  The mall is 12 miles from his home to the library.

Step-by-step explanation:

Since we have given that

Number of miles is from his home from the mall = 15 miles

The school  is \dfrac{1}{2} of the way from his home to the mall.

The library is \dfrac{2}{5} of the way from your school to the mall.

According to question, it becomes,

15=\dfrac{1}{2}x\\\\15\times 2=x\\\\x=30\ miles

So, the number of miles from his home to the library is \dfrac{2}{5}\times 30=2\times 6=12\ miles

Hence, the mall is 12 miles from his home to the library.

How do you round to the nearest cent
Allisa [31]

See the explanation

<h2>Explanation:</h2>

Rounding to the nearest cent is the same as rounding to the nearest hundredth. In order to round this way, you must use the thousandths place so that you can know whether hundredths place rounds up or stays the same.

So the rules is as follows:

  • If the thousandths place is 5 or above, we add 1 to the digit of the hundredths place.

For example:

0.64<u>8</u>3

4: It's in the hundredths place

<u>8</u>: It's in the thousandths place

8 is greater than 5, so we round it as:

0.65

  • If the thousandths place 4 or below, the digit in the hundredths place stays the same.

18.9<u>2</u>3569

9: It's in the hundredths place

<u>2</u>: It's in the thousandths place

2 is less than 5, so we round it as:

18.92
