Answer:

Her hourly rate is <u>$14</u>.

Step-by-step explanation:

Given:

Penelope goes to work after school for 4.5 hours on Mondays, Tuesdays, and Fridays.

She works 8 hours each on Wednesdays or Thursdays.

Now, to find her hourly rate.

So, total hours Penelope work on Mondays, Tuesdays, and Fridays:

4.5+4.5+4.5=13.5\ hours.

And, total hours she work on Wednesdays and Thursdays:

8+8=16\ hours.

Now,<em><u> the total hours each week she work:</u></em>

13.5+16=29.5\ hours.

<u><em>Total money she makes each week</em></u> = $413.

Now, to get the hourly rate we divide the total hours each week she work by total money she makes each week:

413\div 29.5

=\$14.

Therefore, her hourly rate is $14.

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 .

–0.4(3x – 2) + StartFraction 2 x plus 4 Over 3 EndFraction for x = 4
Nadusha1986 [10]

Answer:

0

Step-by-step explanation:

Given

- 0.4(3x - 2) + \frac{2x+4}{3} ← substitute x = 4 into the expression

= - 0.4(3(4) - 2) + \frac{2(4)+4}{3}

= - 0.4(12 - 2) + \frac{8+4}{3}

= - 0.4(10) + \frac{12}{3}

= - 4 + 4 = 0

What is the average rate of change for this quadratic function for the interval
stealth61 [152]
<h3>Answer:   -4  (choice B)</h3>

==========================================================

Explanation:

The table says that when x = 1, the output is y = -2.

So the point (1, -2) is on the parabola.

The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.

Find the slope of the line through those two points. The slope here is the same as the average rate of change.

m = (y2 - y1)/(x2 - x1)

m = (-10 - (-2))/(3 - 1)

m = (-10 + 2)/(3 - 1)

m = -8/2

m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.
