anastassius [24]

Answer:

$cost = \frac{287}{60} +80$

Step-by-step explanation:

So, for 60 square feet they charge = 287

So, for 1 square foot they charge = $\frac{287}{60}$

If they charge the installation fee this becomes = $\frac{287}{60} +80$

We can write an equation to calculate cost by using this $=\frac{287}{60} x +80$

The area of a triangle is 30 square centimeters and its base is 10 cm. What is the height in cm of the triangle

Vesnalui [34]

Answer:

The height of the triangle is $6$ cm.

Step-by-step explanation:

----------------------------------------

The formula for solving the area of a triangle is $A=\frac{1}{2}bh$ where $b$ stands for base and $h$ stands for height.

Let's substitute 30 $cm^2$ for the area and 10 for the base.

$30=\frac{1}{2} (10)h$

-------------------->>>>

Now, let's solve to find the height.

$30=\frac{1}{2}(10)h$

Multiply $\frac{1}{2}$ times $10$

$30=5h$

Divide both sides by 5.

$6=h$

-----------------------------------------

Hope this is helpful.
