Christopher is packing his bags for his vacation. He has 8 unique shirts, But only 5 feet in his bag. How many different groups
marshall27 [118]

Answer:

Christopher can take 56 different groups of 5 shirts.

Step-by-step explanation:

Christopher has 8 unique shirts.

Out of these only 5 can fit in his bag.

So the number of ways in which he can choose 5 shirts from the available 8 is given by \[_{5}^{8}\textrm{C}\]


This can be evaluated as \[\frac{8!}{5!*3!}\]

Simplifying further,

= \[\frac{6*7*8}{1*2*3}\]

= 56

So Christopher has 56 choices to select 5 shirts out of 8.

A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to
Karo-lina-s [1.5K]
<h2>Hello!</h2>

The answers are:

- Length

length=2width=12feet

- Width

width=6feet

- Area

Area=72feet^{2}

<h2>Why?</h2>

We are given the perimeter of a rectangular mat, and we are asked to find the area, and write an equation to determine the length, if feet, of the mat. To solve this problem we need to remember the equation of the perimeter of a rectangle, which is:

Perimeter=2length+2width

Using the given information we have,

36feet=2length+2width

Also, we know that the length is twice the width, so:

length=2width

Then, substituting the second equation into the first equation, we can find the width of the mat.

Substituting, we have:

36feet=2(2width)+2width

36feet=4width+2width

36feet=6width

[tex]\frac{36feet}{6} =width\\width=\frac{36feet}{6} =6feet[/tex]

Then, substituting the width into the second equation, we can find the length of the mat,

Substituting, we have:

length=2width

length=2(6feet)=12feet

Then, finding the area, we have:

A=length*width=12feet*6feet=72feet^{2}

Have a nice day!
