Answer: she needs 6.8 ie 6 hrs 48 min to make exactly 102$ AND

7,8,9,10 hrs to make higher than that.

Step-by-step explanation:

Zoe makes $7 per hr for babysitting

Zoe makes $15 per hr clearing table

Max hrs to work = 14 hrs

Min earn = $130 for 14hrs

He works four(4) hrs babysitting , so he made = $7*4=$28

Hours remaining = 10 hrs

Money remaining to be earned in 10 hrs = 130 - 28= $102

For her to make at least$102 she needs from 7 hrs to 10 hrs

Reason, 15*6=$ 90

90 is less than 102

So from 7 to 10 hrs will meet her requirement and there will be extra gain.

But to make exactly she needs 102/15=6.8 hrs = 6 hrs 48 min

Answer:

7, 8, 9, 10

Step-by-step explanation:

If Zoe worked 4 hours of babysitting at $7 per hour, she earned $28. Therefore, she must earn another $102 to earn at least $130. At $15 per hour, she must work a minimum of 7 hours clearing tables to make at least $102. This is fine since she can work another 10 hours before reaching her maximum of 14 total hours. Therefore, all possible values for the number of whole hours clearing tables that she must work to meet her requirements are 7, 8, 9, 10.

Which point shows the location of 5 – 2i on the complex plane below? On a coordinate plane, points A, B, C, and D are shown. Poi

Romashka-Z-Leto [24]

Answer:

The Point C shows the location of 5-2i in the complex plane: 5 points to the right of the origin and 2 points down from the origin.

Step-by-step explanation:

We have the complex number 5-2i and we have to show the location of the point that represents that number in the complex plane

In the complex plane the real numbers are located in the horizontal axis, increasing to the right. The positives real numbers are at the right of the origin and the negatives to the left.

The complex numbers are located in the vertical axis, with the positives over the origin and the negatives below the origin.

This complex number 5-2i is the sum of a real part (5) and a imaginary part (-2i), so the point will be 5 units rigth on the horizontal axis (for the real part) and 2 units down in the vertical axis (for the imaginary part).
