Answer:

It will be withheld $75 for federal income.

Step-by-step explanation:

Proportions

Assuming the federal income tax is proportional to the earnings, we can establish the following relationship between the income tax (T) and the earnings (E):

T = k.E

Kimberly earned E=$500 and paid T=$50 for federal income tax, With this information, we can calculate the value of k:

50 = k ( 500)

k = 50 / 500

k = 0.1

The model is now:

T = 0.1*E

If Kimberl earns $750 next month, the tax will be:

T = 0.1*($750)

T = $75

It will be withheld $75 for federal income.

West.       A------10miles------B-----------120miles------------------------Town.     East

Answer: C

Step-by-step explanation: The answer is C because it is.

Answer:

2:40 to 3:16

2:40 to 3 is 20 min

Answer:

h=-41

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Answer:

the answer should be c

Step-by-step explanation:

180-90=90

90-41=49

49-1=48

48:6=8

x=8

Answer:

C) 8

Step-by-step explanation:

41 + 6x + 1 = 90° because this is a right angle

42 + 6x = 90 subtract 42 from both sides

6x = 48 divide both sides by 6

x = 8

Answer:

a. 42%

b. 16%

Step-by-step explanation:

a. According to the curve, the bottom 80% of families has about 58% of the income, so the top 20% has about 42%.

b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income.  So the third quintile has about 32% − 16% = 16%.

Answer:

x ≤ 50

Answer:

t=4

Step-by-step explanation:

there nothing more to do

Answer:

its 4 i think

Step-by-step explanation:

|x| = 4    This means: What value can we substitute for x to get an answer of 4?

**You might automatically say: x = 4    because |4| = 4

Yes, you are correct! However, this is not the only answer. You will have two answers for this equation because:

Isn't |-4| = 4 ?

So, this answer is x = 4 or -4.

Answer:

True

When you add two negative numbers the sum is always negative ex.

When you add two numbers with different signs get the difference and get the sign by the larger absolute value ex.

Step-by-step explanation:

Answer:

5000

Step-by-step explanation:

because 5280 minus 280 is 5000 and if u add 720 that is more than 720 so 5000 is correct

Answer:

[tex]17-\frac{6}{5}j[/tex]

Step-by-step explanation:

The first step is to combine like terms. 16 - 4 = 12 + 5 = 17 and [tex]-\frac{2}{5}j - \frac{4}{5}j[/tex] = [tex]-\frac{6}{5}[/tex]j

Now combine those two to get 17 [tex]-\frac{6}{5}[/tex]j

Answer:

16 : 23

Step-by-step explanation:

23 is a prime number, so it can't be reduced

Answer:

|-5|

Answer: It is 35/72

Step-by-step explanation:

1 3/8=11/8

11/8-8/9

11/8=99/72

8/9=64/72

99/72-64/72= 35/72

Answer:

The LCM is:

[tex](a^2+b^2)(a+b)(a-b)[/tex]

Step-by-step explanation:

Given polynomials are:

[tex]a^2+b^2\\a^4 - b^4[/tex]

We can use factorization to find the LCM of the given polynomials.

Taking the second polynomial, using the identity

[tex]a^2 - b^2 = (a+b)(a-b)[/tex]

Applying on 2nd polynomial

[tex](a^2)^2-(b^2)^2\\=(a^2+b^2)(a^2-b^2)\\=(a^2+b^2)(a+b)(a-b)[/tex]

We can see that [tex]a^2+b^2[/tex] is common in both polynomials, it will be counted only one time. The LCM of given polynomials is:

[tex](a^2+b^2)(a+b)(a-b)[/tex]

Answer:

x+y= 136099

&'&**!;;#$*$*$$-%-%=-$*$&2=28%%"

Answer:

(0,2.5) and (1,1)

Step-by-step explanation:

Given

[tex]3x + 2y = 5[/tex]

Required

Determine the points that satisfy the equation

To do this, we substitute values for x and y in the equation.

Let x = 1

Substitute 1 for x in [tex]3x + 2y = 5[/tex]

[tex]3(1) + 2y = 5[/tex]

[tex]3 + 2y = 5[/tex]

Make 2y the subject

[tex]2y = 5 - 3[/tex]

[tex]2y = 2[/tex]

Solve for y

[tex]y = 1[/tex]

Hence, a point is: (1,1)

To determine another point, take x as 0

Substitute 0 for x in [tex]3x + 2y = 5[/tex]

[tex]3(0) + 2y = 5[/tex]

[tex]0 + 2y = 5[/tex]

[tex]2y = 5[/tex]

Solve for y

[tex]y = \frac{5}{2}[/tex]

[tex]y = 2.5[/tex]

Hence, another point is (0,2.5)
