Answer:

This not true because the monomial may have the same degree, but different variables. So, Rebecca forgot to include the variables and the number variables when determining her answer. Keep in mind the variable also determines the like terms. Ex: 5y^2 and 5x^2 aren't like terms just because the degrees are the same. Good luck.

Malliki Williams earned a $48,000 from royalties on her cookbook.She paid a 28% income tax on these royalties. The balance wasin

Nikitich [7]

Answer:

$20000 and $14560

Step-by-step explanation:

First, we need to get the total tax paid by Malliki Williams

To get that, we have to multiply her income tax (28%) by total royalties ($48000)

28% of $48000 = $13440

Balance after tax = $48000 - $13440

Balance = $34560

She invested some of the balance ($34560) at the rate of

3.25% ---- First investment

1.75% --- Second investment

Assume her first investment is x dollars

Definitely, her second investment would be $34560 - x

3.25% of x + 1.75% (34560 - x ) = 904.8

0.0325x + 0.0175(34560-x) = 904.8 ----- Open the bracket

0.0325x + 604.8x - 0.0175x = 904.8 ------ Collect like terms

0.0325x -0.0175x =904.8 - 604.8

0.015x = 300 ------ Divide both sides by 0.015

x = 300/0.015

x = 20000

Remember that x represents her first investment

Her second investment is $34560 - $20000 =$14560

2. Six cell phones weigh 46.2 ounces.

Zigmanuir [339]

Answer:

Yes, they're proportional and the constant of proportionality is 7.7.

Step-by-step explanation:

They are proportional because 46.2÷6=7.7 and 107.8÷14 also equals 7.7. This also means that 7.7 is the constant of proportionality.

Find the area of the circle. Round your answer to two decimal places, if necessary.

Arlecino [84]

Answer:

Step-by-step explanation:

The equation for the area of a circle is A= $\pi$ $r^{2}$ .

A=area

r=radius

We were given the diameter of the circle not the radius, so we need to solve for the radius.

Radius=(1/2)Diameter So,

(1/2)6=3mm

Now we can solve for the area.

3^2(3.1415926)=28.2743mm

Now round to two decimal places.

28.27mm
