1. Danielle earns more than the Mackenzie.

2. $0.8

Step-by-step explanation:

Given data:

Danielle earns = $36.80

How much time Danielle works =  4 hours

Mackenzie earns = $50.40

How much time Mackenzie works = 6 hours

Question: Who earns more per hour?

Solution:

Earning of Danielle per hour = 36.80/4 = $9.4 per hour

Earning of Mackenzie per hour = 50.40/6 = $8.4 per hour

Explanation:

Hence the Danielle earns more than the Mackenzie. Denielle earns $9.2 and Mackenzie earns $8.4 per hour. Mackenzie work more hours than Danielle but the per hour earning of Danielle is more.

Per hour earning of Danielle ≥ Earning of Mackenzie per hour.

Question: How much more?

Solution:

More earning of Danielle from Mackenzie = Per hour earning of Danielle - Earning of Mackenzie per hour.

By putting the values in above equation:

More earning of Danielle from Mackenzie = $9.2 - $8.4 = $0.8

Explanation:

As we know Danielle earns more than the Mackenzie. Denielle earns $9.2 and Mackenzie earns $8.4 per hour. B taking the difference of both incomes, Danielle earns $0.8 more than the Mackenzie.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
