Answer:

7. C

8. D

Step-by-step explanation:

7. The interest rate is 8% or .08. You find that by solving I=Prt (interest=original amount*rate*time in years)

8. The discounted price would be $48 (80*(1-.40)) Then you multiply that 48 by .08 and add that amount to the $48.

(3,4) and (-5,6) are "coordinate planes".

These appear in algebra and math when you're graphing. These coordinate planes consist of "x" and "y" (x,y). The x's (which are 3 and -5 in your situation) should be graphed accordingly using the x-axis and the y's (which are 4 and 6 in your situation) should be graph accordingly using the y-axis.

Find the midpoint of AB A.(-2,-3) B.(16,4) C.(-2,-11) D.(4,-10)
zheka24 [161]

Answer:

(-2,-1)

Step-by-step explanation:

Using the graph find the coordinates for A and B.

A (-4,2) and B is (0,-4)

Midpoint formula is (x1 + x2)/2 , (y1+y2)/2

x value of the midpoint= (-4+0)/2 = -2

y value of the midpoint= (2 + -4)/2 = -2/2= -1

Midpoint is (-2, -1)

Your take home pay is $1500 and you have 22% withheld in taxes. What is your gross pay?
wlad13 [49]

We have been given that the take home pay is $1500 and 22% is withheld as taxes.

Let us assume that the gross pay is x dollars. Therefore, take home pay must be 78% of x because 22% of the pay is withheld as taxes, so you get to take home only 78% of the gross pay.

Since we have been given that take home pay is $1500 and it is 78% of the total gross pay. Therefore, we can set up an equation:

78\%\text{ of }x=1500\\\frac{78}{100}x=1500\\0.78x=1500\\x=\frac{1500}{0.78}\\x=\$1923.08

Therefore, gross pay is $1923.08
