Rachel earned $85.25 for working 6 1 4 hours. How much does Rachel earn per hour?

GaryK [48]

Answer:

Rachel earns per hour is $ 13.64 .

Step-by-step explanation:

As given

Rachel earned $85.25 for working $6 \frac{1}{4}$ hours.

i.e

Rachel earned $85.25 for working $\frac{25}{4}$ hours.

Now calculate earning of Rachel for 1 hour .

$Rachel\ earning\ for\ one\ hour = \frac{Total\ earning}{Total\ time}$

$Rachel\ earning\ for\ one\ hour = \frac{85.25}{\frac{25}{4}}$

$Rachel\ earning\ for\ one\ hour = \frac{85.25\times 4}{25}$

$Rachel\ earning\ for\ one\ hour = \frac{341}{25}$

$Rachel\ earning\ for\ one\ hour = \$ 13.64$

Therefore Rachel earns per hour is $ 13.64 .

Can some help me out with this EXTRA POINTS!!

Butoxors [25]

Answer: ≈ 185.73009

Step-by-step explanation:

area of square: $length^{2}$

area of circle: $\frac{radius^{2} * \pi }{y}$

length: 15

radius = diameter/2

radius: 5

area of square - area of circle = area between square and circle:

$15^{2} - \frac{5^{2} * \pi }{2} = 225 - \frac{25\pi}{2}$ ≈ 185.73009

hope it helps!
