You make $52,000 a year. Your state income tax rate is 2.5%. The state income tax allowance is $1500 per person and you have three allowances. They are yourself, your spouse and one child. How much income tax do you owe?
Answer:
1,187.50
Step-by-step explanation:
Answer:
Step-by-step expiation
we know that their is an income tax rate of 2.5%, Since their is more than one person within the household, we will multiple the tax rate by 3
2.5% = 0.025
0.025 x 3 = 0.075
Then we will multiple the tax rate by our principal,
52,000 x 0.075 = 3,900
52,000 - 3,900 = 48,100
This will then give us our answer of $3,900 for the income tax rate that is owed, and as well as their new total income.

Allen wants to have a mean of 90 on his math quizzes. So far, he has scored 86, 94, 88, 95, and 89. What is the least score that Allen needs on his next quiz to have a mean of 90?
Answer:
88
Step-by-step explanation:
[tex] \frac{86 + 94 + 88 + 95 + 89 + x}{6} = 90[/tex]
The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:
[tex]86 + 94 + 88 + 95 + 89 + x = 540[/tex]
[tex]452 + x = 540[/tex]
[tex]x = 88[/tex]
Thus, Allen needs at least an 88 to obtain a mean of at least 90.

2.2 results in a true equation, 2.2 is a solution to the equation.
Step-by-step explanation:
Step 1. Substitute the number for the variable in the equation.
Step 2. Simplify the expressions on both sides of the equation.
Step 3. Determine whether the resulting equation is true.
If so, the number is a solution.
If not, the number is not a solution.
Find the smallest value of m such that the LCM of m and 34 is 374.
Answer:
11
first you use a number tree
34 374
/\ /\
2 17 2 187
/\
11 17
express the numbers in prime factors
374=2×11×17
34 =2×17
in finding LCM you use the highest prime factors in this case the highest prime factors are 2, 11 and 17
So m factors are 2 and 11
which means m is 2×11=22
22 in its smallest form is 11

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 363 square feet. The width of the basement is 1 3 its length. What is the length of Louis's basement? The length is feet.
Answer:
the length is 33 feet
Step-by-step explanation:
The computation of the length is shown below:
Let us assume the length be x
So the width be 1 by 3 x
And the area is 363 square feet
So
As we know that
Area = length × width
363 = x × 1 ÷ 3 x
363 = 1 ÷ 3x^2
Now
363 × 3 = x^2
1089 = x^2
x = 33 feet
hence, the length is 33 feet

is y+7=2x a direct variation
Answer:
No, y+7=2x does not represent direct variation
Step-by-step explanation:
No, y+7=2x does not represent direct variation, because of the constant (initial value) 7.
y = 2x represents direct variation; y = 2x - 7 does not.

Answer:
SI = 2052.61 ft
Step-by-step explanation:
cos 13 = 2000/SI
0.9744 = 2000/SI
multiply both sides by SI:
(SI)(0.9744) = 2000
divide both sides by 0.9744:
SI = 2052.61 ft
