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\%

If bd = 7x-10, bc = 4x-29, and cd = 5x-9, find each value
Airida [17]

Answer:

bd=88, bc=27, cd=61

Step-by-step explanation:

In this problem we have that

bd=bc+cd

we have

bd=7x-10

bc=4x-29

cd=5x-9

substitute the values and solve for x

7x-10=(4x-29)+(5x-9)

Group terms that contain the same variable in the right sides

7x-10=(4x+5x)+(-29-9)

Combine like terms in the right side

7x-10=9x-38

9x-7x=-10+38

2x=28

x=14

<u><em>Find the value of bd</em></u>

bd=7(14)-10=88

Find the value of bc

bc=4(14)-29=27

<u><em>Find the value of cd</em></u>

cd=5(14)-9=61

The revenue function for a dog food company is modelled by the function R(d) = - 40d^2 + 200d, where d is the price for a can of
marysya [2.9K]

Answer:

The breakeven prices are d_1=4.225 and d_2=1.775.

Step-by-step explanation:

The break even point represents the point in which the profit is zero. In other words, where the revenue equals the cost.

We have functions that describe both the revenue and the cost. The brackeven price is such that R(d)=C(d):

R(d) = - 40d^2 + 200d\\\\C(d) = 300-40d\\\\\\R(d)=C(d)\\\\-40d^2+200d=300-40d\\\\-40d^2+240d-300=0\\\\\\d=\dfrac{-240\pm\sqrt{240^2-4(-40)(-300)}}{2(-40)}\\\\\\d=\dfrac{-240\pm\sqrt{57600-48000}}{-80}\\\\\\d=\dfrac{-240\pm98}{-80}=3\pm1.225\\\\\\d_1=3+1.225=4.225\\\\d_2=3-1.225=1.775

Find the values for k so that the intersection of x = 2k and 3x + 2y = 12 lies in the first quadrant.
RUDIKE [14]

Answer:

0 < k < 2

Step-by-step explanation:

<u>In the first quadrant both of x and y get positive values, so </u>

  • x > 0 and y > 0
  • x = 2k, k > 0

<u>And replacing x with 2k in the second equation:</u>

  • 3x + 2y = 12
  • 3*2k + 2y = 12
  • 2y= 12 - 6k
  • y = 6 - 3k

<u>Since y > 0:</u>

  • 6 - 3k> 0
  • 2 - k > 0
  • k < 2

<u>Combining both k > 0 and k < 2, we get:</u>

  • 0 < k < 2
