natka813 [3]

Answer:

7.5 Quarts

Step-by-step explanation:

D'Naisa mixed the following:

  • 1 gallon of orange paint
  • 2 quarts of yellow paint
  • 3 pints of red paint.

We are to determine in total, the number of quarts of paint that she mixed. this is done by converting each of the volume to quart.

<u>1 gallon of orange paint</u>

  • 1 gallon = 4 Quarts
  • Orange Paint=4 Quarts

<u>3 pints of red paint.</u>

  • 1 pint =0.5 quart
  • 3 Pints =3 X 0.5 Quart
  • =1.5 Quart of red paint

Therefore,

Total Volume of Paint Mixed in quart= Volume of Orange+Yellow+Red

=4+2+1.5

=7.5 Quarts

If Lisa’s gross pay was $1204.89 and her net pay was $818.44, about what percent of her pay was deducted?
Amanda [17]

Answer:

About 32% of her pay was deducted ⇒ 2nd answer

Step-by-step explanation:

Lisa’s gross pay was $1204.89

Her net pay was $818.44

We need to find the percentage of the amount deducted from her pay

<u><em>Lets calculate the deduction amount</em></u>

The deduction amount is the difference between the gross pay and

the net pay

∵ The amount deducted = gross pay - net pay

∵ Gross pay = $1204.89

∵ Net pay = $818.44

∴ The amount deducted = 1204.89 - 818.44 = $386.45

<u><em>Now lets find the percentage of the amount deducted </em></u>

∵ Percent of deducted = [amount deducted/gross pay] × 100%

∵ The amount deducted = $386.45

∵ Gross pay = 1204.89

∴ Percent of deducted = \frac{386.45}{1204.89} × 100%

∴ Percent of deducted = 32.07%

<em>About 32% of her pay was deducted</em>

Combine like terms to create an equivalent expression 2s+ (-4s) pls help
pav-90 [236]

The equivalent expression to 2s + (-4s) is -2s.

Step-by-step explanation:

Step 1:

In sums like these, it is easier to take the common term out of the simplification.

In the expression 2s + (-4s), the common term between 2s and -4s is the term s. So we take the term s as the common factor.

So taking s out of 2s + (-4s) we get s (2+(-4)).

Step 2:

If we multiply a positive with a negative we get a negative. S0 +(-4) = -4.

2s + (-4s) = s (2-4) = s(-2) = -2s.

So the equivalent expression to 2s + (-4s) is -2s.
