Addison earned a gross income of $42,750 last year. She made $537.56 in IRA contributions, donated $918 to her favorite charity and paid $1,351.35 in home mortgage interest. If Addison claims a standard deduction of $5,700 and her exemption is $3,650, what is her taxable income?
$30,593.09
$36,293.09
$31,511.09
$32,862.44
Answer:
The answer is: $ 30,593.09.
Step-by-step explanation:
To the gross income of $ 42,750 of Addison, the amounts of the payments made must be deducted, that is, $ 537.56, $ 918, $ 1,351.35, plus the exemption of $ 3,650, and also if they grant him the standard deduction of $ 5,700; Your taxable income would be: $ 42,750 - ($ 537.56 + $ 918 + $ 1,351.35 + $ 3,650 + $ 5,700) = $ 30,593.09
The answer is: $ 30,593.09.

You can use a minus sign to make a negative number like -2. what happens if you put a plus sign before a number? what about 2++2?
Final answer:
A plus sign before a number does not change its value. In the expression 2++2, the two plus signs next to each other are interpreted as a positive number followed by another positive number.
Explanation:
When you put a plus sign before a number, it doesn't change the value of the number.
The plus sign is just a symbol to indicate that the number is positive.
In the expression 2++2, the two plus signs next to each other are not a valid mathematical operation.
Instead, it is interpreted as a positive number followed by another positive number.
So, 2++2 is equal to 2+2, which is 4.

Triangle A B C with angle A measuring thirty degrees, angle B measuring seventy degrees and angle C marked x
Answer: In a triangle, the sum of the 3 angles is always equal to 180°
Then if the angle A is equal to 30°, the angle B is equal to 70°, what is the angle C?
if x is the angle C, and using the first statement, we got:
30° + 70° + x = 180°
100° + x = 180°
x = 180° - 100° = 80°
So the angle of C is equal to 80°.
A car travels 252 miles in 5 hours and 15 minutes. how many miles does it travel per hour?
Answer:
48 miles per hour
Step-by-step explanation:
5hrs and 15minutes = 315minutes
If 252 = 315
x = 60
By cross multiplication
315x = 60 * 252
315x = 15,120
x = 15120/315
x = 48 miles per hour

What is the remainder when 4x4 − 10x3 + 14x2 + 7x − 19 is divided by 2x − 1
The remainder when [tex]4x^4 - 10x^3 + 14x^2 + 7x - 19[/tex] is divided by 2x − 1 is -13.
The given expressions are [tex]4x^4 - 10x^3 + 14x^2 + 7x - 19[/tex] and 2x-1.
What is the remainder?The Remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.
The division of the given expressions are given below:
2x³-4x²+5x+6
___________________
2x-1 | [tex]4x^4 - 10x^3 + 14x^2 + 7x - 19[/tex]

Which equation could be used to solve the problem?
Mr. Guzman drove his car 1080 miles in 6 weeks.
If he drove the same distance every week, which equation shows how far he drove each week (d)?
A.
d = 6 ÷ 1080
B.
d = 1080 – 6
C.
d = 1080 • 6
D.
d = 1080 ÷ 6
Mr. Guzman drove 1080 miles in 6 weeks. To find the distance driven each week, use the equation d = 1080 ÷ 6, which equals 180 miles per week. Therefore, the correct equation is option D.
Mr. Guzman drove 1080 miles in 6 weeks. We need to find out how far he drove each week if he drove the same distance every week.
Identify the Total Distance Driven: 1080 milesIdentify the Total Time Period: 6 weeksSet Up the Equation: Since Mr. Guzman drove the same distance every week, we use the formula:
d = Total Distance / Total Time.Substitute Known Values:
d = 1080 ÷ 6Calculate the Result:
d = 180 miles per weekThe correct equation that shows how far Mr. Guzman drove each week is d = 1080 ÷ 6, which corresponds to option D.

On a given blueprint, 1 inch=12 feet. if the dimensiopns of a recreation room on the blueprint are 2 onches x 1.75 inches. what are its actual measurements
Unit conversion is the conversion of one unit to another unit with its standard conversion.
The actual dimension of the recreation room is 24 feet x 21 feet.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1m = 100 cm
1 hour - 60 minutes
We have,
Recreation room dimension on the blueprint:
= 2 inches x 1.75 inches ______(A)
Scale factor:
1 inch = 12 feet
The actual dimension of the recreational room:
1 inch = 12 feet
Multiply 2 on both sides.
2 inches = 24 feet _____(1)
1 inch = 12 feet
Multiply 1.75 on both sides.
1.75 inches = 1.75 x 12 feet
1.75 inches = 21 feet ______(2)
From (1) and (2) and (A) we get,
= 2 inches x 1.75 inches
= 24 feet x 21 feet
Thus,
The actual dimension of the recreation room is 24 feet x 21 feet.
