Could someone please help me with this question

bogdanovich [222]

Answer:

10 units

Step-by-step explanation:

Area of a triangle is $\frac{h*b}{2}$ = Area

where h is the height, and b is the base

We can substitute these values into the area equation and get:

$\frac{x*10}{2} = 50$

Multiply both sides by 2:

x * 10 = 100

Divide both sides by 10:

x = 10

The missing side is 10 units long

A student's cost for last semester at her community college was $2800. She spent $308 of that on books. What percent of last sem

Rudik [331]

You want to divide the cost of the books by the total costs.

308/2800 = 0.11

You then need to convert 0.11 to a percent: 0.11 = 11%

Therefore, 11% of her costs last semester were spent on books.

That’s too much!
