Instead of it being a square root, it becomes a cube root sign. So find the cube root of whatever number is inside the sign.

█ Solution <span>█

</span><span>✦ Since Olivia has already saved 8 dollars, the inequality would be addition.
</span><span>✦ The only two choices for that would be choice #1 or #2
</span>✦ Since she's earning 7 dollars per hour, the answer would be the first choice.
✦ 8 + 7n ≥ 36, so n ≥ 4

Answer: Choice 1

1. Quadrilateral EFGH is an isosceles trapezoid. If mG is four times mH, what is mE? A)18° C)72° D)144° B)36°​
Maslowich

Answer:

<E = 36 degrees (Answer B)

Step-by-step explanation:

Recall that the addition of all internal angles in a quadrilateral must equal 360 degrees. Then we can write the equation that states this as:

<E + <F + <G + <H = 360

Notice as well that we are dealing with an isosceles trapezoid, so there is a symmetry along the line that passes through the midpoints of sides FG and EH (the two bases). That means that the measures of angles <F = <G  and <E = <H .

The previous equation then can be written as:

<H + <G + <G + <H = 360

Also, since we are told that <G = 4 <H, we can use this info in the equation as shown below:

<H + 4 <H + 4 <H + <H = 360

10 <H = 360

divide both sides by 10 to isolate <H

<H = 360 / 10

<H = 36

Since as we mentioned, <E equals <H, we can state that

the measure of <E = 36 degrees (Answer B)
