Marie will earn $15 per hour at a new job. During training, she will earn $10 per hour. What percent of Marie’s regular hourly r

Hitman42 [59]

Answer: 66.67%

Step-by-step explanation:

Given: The amount Marie will earn at a new job = $15 per hour

The amount she will earn during the training = $10 per hour

The percent of Marie’s regular hourly rate she will earn during training is given by :-

$P=\frac{\text{Rate of amount she earn in training }}{\text{Rate of amount she earn at new job }}\times100\\\\\Rightarrow\ P=\frac{10}{15}\times100\\\\\Rightarrow\ P=66.66666\%\approx66.67\%$

$\text{Apply Pythagorean theorem,}\\ \\~~~~~~12^2 = 3^2 + h^2\\\\\implies h^2 = 12^2 -3^2\\\\\implies h^2 = 144-9\\\\\implies h^2 = 135\\\\\implies h = \sqrt{135}\\\\\implies h = 3\sqrt{15}\\\\\implies h \approx 11.62$

Sketch the graph of each line.<br> 2x-5y=25

ki77a [65]

Well, you transform the standard form equation into slope-intercept form (y=mx+b), since you can only graph it using this form.

First of all, the layout of the equation is $Ax+By=C$

So, in this case, A is 2, B is 5, and C is 25.

Now, to put it into slope intercept form, you either use the formula to change it and solve it:

$y= \frac{-A}{B}x+ \frac{C}{B} \\ y= \frac{-2}{-5}x+ \frac{25}{-5} \\ \\ y= \frac{2}{5}x-5$

Or you can just solve for y:

$2x-5y=25 \\ 2x-5y-2x=25-2x \\ -5y=-2x+25 \\ \frac{-5y}{-5}= \frac{-2x+25}{-5} \\ \\ y= \frac{2}{5}x-5$

In addition, I attached what the graph looks like.

Hope this helps!

The lengths of the sides of a triangle are in the extended ratio 6 : 7 : 10. The perimeter of the triangle is 46 cm. What are th

skad [1K]

Answer:

12.54 cm, 14.63 cm, 18.81 cm

Step-by-step explanation:

6x + 7x + 9x = 46 cm

22 x = 46 cm

x = 2.09

So the sides are:

12.54 cm, 14.63 cm, 18.81 cm
