Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of pai

Deffense [45]

Answer:

$1 \dfrac{1}{4} \ liters$

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

$x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}$

$x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }$

$x (L) = \dfrac{2 L }{ \dfrac{8}{5} }$

$x (L) = \dfrac{2 L\times 5 }{ 8 }$

$x (L) = \dfrac{10 \ L }{ 8 }$

$x(L) =1 \dfrac{1}{4} \ L$

Study the following data set.

Katen [24]

The interquartile range of the data set is 8

<h3>How to solve for the interquartile range</h3>

To do this we have to arrange in ascending order

= 8,9,9,9,10,11,13,15,17,18,22

Q2 = The median of the data is 11.

We have to find the median of the half before 11 and the median of the half after 11.

We would have

8,9,9,9,10

Q1 = 9

And 13,15,17,18,22

Q3 = 17

The interquartile range is

Q3 - Q1

= 17 - 9

= 8

The interquartile range of the data set is 8

If 4 books equals to 5 months how many books equals 15 months

Murrr4er [49]

Answer:

12 months

Step-by-step explanation:

Based on the question

4 books equals to 5 months

x books equals to 15months

To determine the value of X we will have to cross multiply,it means

5x=15×4

5x=60

Divide both sides by 5

x=12

Therefore,x=12

Which means 12 books equals to 12 months
