The perimeter of the triangle below is 80 units. Find the length of side PR

Mathematics

serg [7]3 years ago
5 0

Answer:

32

Step-by-step explanation:

The perimeter is equal to sum of side lengths

4x + z + 3 + 5z - 3 = 80 add like terms

10z = 80 divide both sides by 10

z = 8 PR is 4z so 8*4 = 32

Choose a fraction that makes the following sentence true. 0.1 is a rational number because it can be written as ___.
pychu [463]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

0.1 is a rational number because it can be written as \dfrac{p}{q} form.

So, we can write it as

0.1=\dfrac{0.1}{1}\\\\=\dfrac{0.1\times 10}{1\times 10}\\\\=\dfrac{1}{10}

so, it can be written as \dfrac{1}{10}

Hence, option 'a' is correct.

A woman wants to build a rectangular garden. She plans to use a side of a shed for one side of the garden. She has 84 yd of fenc
Ivan
Let x denote the length of the side of the garden which is covered fenced by a shed, and \frac{A}{x} be the width of the garden.

The perimeter of a rectangle is given by 2(length + width)
i.e. 2x + \frac{A}{x} = 84
which gives:
A = 84x - 2x^2

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e. \frac{dA}{dx} =84-4x=0 \\ 4x=84 \\ x=21

Therefore, the maximum area of the garden enclosed is given by
84(21)-2(21)^2=1764-2(441)=1764-882=882 \, yd^2
