Irina18 [472]

Answer:

Her weekly allowance is $8.

Step-by-step explanation:

Let the weekly allowance of Ming is $x.

If she spends half of her weekly allowance playing mini-golf and to earn more money her parents let her wash the car for $5, then the remaining amount of money that she has = (\frac{x}{2} + 5) dollars.

Now, given that (\frac{x}{2} + 5) = 9

⇒ \frac{x}{2} = 4

⇒ x = $8

Therefore, her weekly allowance is $8. (Answer)

What is the area of the figure? Round to the nearest tenth.
nikdorinn [45]

Answer:

letter A

Step-by-step explanation:

This is made up of 4 triangular segments. If we assume the cross section is perpendicular then we can use the 1/2b*h formula for each piece with the given values. So we have 2 triangles with the formula: 1/2(3)*(4.5)=6.75 * 2 triangles = 13.5.

Then for the bottom 2 you have 1/2(3)*7.5=11.25, times 2 triangles =22.5

So, 13.5+22.5=36, or letter A
