If it takes 5 1/7 yards of material to make a pillow cover, how much material will be needed to make 9 pillow covers?

s2008m [1.1K]

$\text{Answer: }46\frac{2}{7}\text{ yards is needed to make 9 pillow covers.}$

Step-by-step explanation:

Since we have given that

Material needed to make a pillow cover is given by

$5\frac{1}{7}\ yards=\frac{36}{7}\ yards$

We need to calculate the material which will be needed to make 9 pillows covers.

So, we use the "Multiplication Operation" as we need the value for more pillow covers :

$9\times \frac{36}{7}\\\\=\frac{324}{7}\\\\=46\frac{2}{7}\ yards$

$\text{Hence, }46\frac{2}{7}\text{ yards is needed to make 9 pillow covers.}$

A certain four-cylinder combination lock has 50 numbers on it.

It is a four cylinder combination lock

Each cylinder has 50 numbers

So we have to choose 4 numbers for 4 cylinders

_____ , ______ , ______, _____

you turn to a number on the first cylinder

We have 50 numbers so we have 50 combinations

__50___ , ______ , ______, _____

Repetitions are allowed so we do the same for remaining three

50 , 50 , 50 , 50

50 * 50 * 50* 50 = 6250000

There are 6250000 different lock combinations .
