Answer:

17 ft

Step-by-step explanation:

Use pythagorean theorem:

{a}^{2} + {b}^{2} = {c}^{2}

The rectangular storage unit is split into 2 right triangles since it is 17 feet diagonally. So, 17 feet is the hypotenuse of the right triangle.

{8}^{2}  +  {x}^{2}  ={17}^{2}

Once you solve everything you will find that x^2 = 225, so x = 15 ft. That is the length of the storage unit.

Given:

The number is -\dfrac{7}{5}.

To find:

The location of the given number of the number line.

Solution:

We have,

Number=-\dfrac{7}{5}

It can be written as

Number=-\dfrac{5+2}{5}

Number=-\dfrac{5}{5}-\dfrac{2}{5}

Number=-1-\dfrac{2}{5}

It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.

The mixed fraction form of given number is

Number=-(1+\dfrac{2}{5})

Number=-(1\dfrac{2}{5})

Number=-1\dfrac{2}{5}

Divide the number in 5 equal parts between two consecutive integers.

Now each unit represents \dfrac{1}{5}.

Since Number=-1-\dfrac{2}{5}, therefore, it is 2 units left from -1.

The number line is given below.

m_a_m_a [10]

Answer:$6/Yard

Step-by-step explanation:

You make it into an algebraic expression, 2.5x=15.

Then, you divide both sides by 2.5

2.5x=15,   2.5x/2.5 =x, 15/2.5=6.

x=6.

x represents the amount of dollars per yard.

A) Garage A = 3x
Garage B = 2x + 2
b) 2x + 2 = 3x
x = 2
c) the solution, 2, means the number of hour which both garages would have the equal amount of cost. In this case, in 2 hours, they would be equal in cost.
