rodikova [14]

Answer:

The monthly net pay is $1555 .

Step-by-step explanation:

As given

Quintina decided to increase the deduction percentage of her federal income tax rate from 14% to 16%.

Quintina’s gross pay per month is $2,100.

16% is written in the decimal form .

= \frac{16}{100}

= 0.16

Federal income tax = 0.16 × Gross pay

                                = 0.16 × 2100

                                = 336

Monthly net pay = Gross  pay - Federal income tax  -  State Income Tax - Social Security - Medicare

                           = 2100 - 336 - 89 - 85 - 35

                          = 2100 - 545

                         = $1555

Therefore the monthly net pay is $1555 .

Solve T=L(2+RS) for R
True [87]

Answer:

Step-by-step explanation:

I would begin by distributing the L. It will be easier in the end to do it this way. There are a couple of ways you can do this, but distribution is the easiest. After you distribute the L you have

T = 2L + LRS

Next subtract the 2L to get

T - 2L = LRS. Lastly, to isolate the R, divide away the LS to get

\frac{T}{LS}-\frac{2L}{LS} = R  In that second term, the L's cancel each other out, leaving us with

\frac{T}{LS}-\frac{2}{S} = R

The answer is <span>Sum of Cubes.

Since there is sign +, we expect it to be the sum. Among all choices, only the last one includes summation, and that is sum of cubes.

Let's check it out.
Sum of cubes can be expresses as:
a</span>³ + b³ = (a + b)(a² - ab + b²)

Let's see what are cube roots of 125 and 8: 
∛125 = ∛5·5·5 = ∛5³ = 5     ⇒     a = 5
∛8 = ∛2·2·2 = ∛2³ = 2     ⇒     b = 2

Now, let's implement that in the equation of sum of cubes:
5³ + 2³ = (5 + 2)(5² - 5·2 + 2²)
125 + 8 = 7 · (25 - 10 + 4)
133 = 7 · 19
133 = 133

Therefore, sum of cubes is the right answer.

Let

h ----> the height of the tree

we know that

The tree casts a shadow that is 27 feet long

Your friend is 5 feet tall and casts a shadow that is 4.5 feet long

so

using proportion

Find out the height of the tree

\frac{h}{27}=\frac{5}{4.5}\\\\h=27(5)/4.5\\\\h=30\ ft
