- A married couple decided to file their taxes jointly. Their joint (total) income for the
year is $155,920. Since the couple does not have any kids yet, they are required to
pay a 30% annual income tax rate.
How much does the couple have to pay in income taxes for the year?
Answer:
They will pay $46,776 in income taxes. The money they will have after income taxes is $109,144.
Step-by-step explanation:
Because this problem involves a deduction of a percentage, you first need to multiply 155,920 by 30% in its decimal form - .30.
Then, with that answer - 46,776 - you subtract it from their total income - 155,920 - and get 109,144.
Now you have what they lose and what they have after the deduction.
So, they will pay $46,776 in income taxes and keep $109,144.
Hope this helps :)
Solve 3,200 divided by 10 using a area model

Write an equation of a line that passes through the point (2,0) and is perpendicular to the line y=−12x+3.
Answer:
Equation of a line that passes through the point (2,0) and is perpendicular to the line y=−12x+3 is
[tex]y = 2x-4[/tex]
Step-by-step explanation:
Slope of the line y=−12x+3 is m1=-12
We know slopes of perpendicular lines are negative reciprocals of each other. Therefore m2=2
Equation of line in point slope form is
[tex]y-y_1 = m_2 (x-x_1)[/tex] ----------- (1)
Here
[tex]m_2 = 2 \ \ \ and \ \ \ (x_1, y_1) = (2, 0)[/tex]
Substituting values in equation (1)
[tex]y-0 = 2 (x-2)[/tex]
[tex]y = 2x-4[/tex]

Answer:

Step-by-step explanation:
Given
See attachment
Required
Determine the surface area
The figure is made up of two cuboids and the surface area of a cuboid is:
[tex]Area = 2LB + 2LH + 2BH[/tex]
Because the bottom part of the upper piece is not visible, the area is calculated as:
[tex]Area = 2LB + 2LH + BH[/tex]
This gives:
[tex]Area = 2 * 5*4 + 2 * 4 * 2 + 5 * 2[/tex]
[tex]Area = 66[/tex]
For the bottom piece:
We calculate its area as [tex]Area = 2LB + 2LH + 2BH[/tex]. However, the area of the invisible part will be subtracted.
So, we have:
[tex]Area = 2*3*5 + 2*3*5 + 2*5*5 - 2*5[/tex]
[tex]Area = 100[/tex]
The total surface area is:
[tex]Total = 66 + 100[/tex]
[tex]Total = 166cm^2[/tex]

the nearest tenth.
8 cm
[ ? ] cm2
Answer: 110.1
Step-by-step explanation:
The area of regular pentagon with side length of 8cm is 110.11 cm² .
Given,
Side length = 8cm
Now,
Area Regular pentagon = 1/4(√5(5 + 2√5)) * a²
a = side length of regular pentagon.
Substitute the value in the formula,
Area of regular pentagon = 1/4 (√5·(5+2·5)) * 8²
Area = 110.11cm²

Hence, answer is 1.The students in Mr. Sanchez's class are converting distances measured in miles to kilometers. To estimate the number of kilometers, Abby takes the number of miles, doubles it, then subtracts 20% of the result. Renato first divides the number of miles by 5 and then multiplies the result by 8.
Write an algebraic expression for Abby's method.
Write an algebraic expression for Renato's method.
Step-by-step explanation:
hay! these is my answer,,,,,, I hope these will help
Abby’s Expression:
Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m
2m − (0.2)2m
Renato’s Expression:
Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:
8(m/5)
Jessie is going to the county fair. The cost of admission is $5.00 and it is $2.00 for each ride. If Jessie has $19.00, Write an equation to determine how many rides Jessie can ride.
Answer:
x=7, Jessie can ride 7 rides with $19
Step-by-step explanation:
The cost of admission is $5.00 and it is constant,
Then for each ride the cost is $2.00
If we let the number of rides be X, then the cost function, C(X) will be given as
C(X)=5+2X
If Jessie has $19, then we can equate the cost function to $19 and solve for x
5+2x=19
Subtracting 5 on both sides,
2x=19-5
2x=14
x=7

Answer:
7x² - 2x + 4

(5x² + 2x + 11) - (7 + 4x - 2x²) = 5x² + 2x + 11 - 7 - 4x + 2x² =
(5x² + 2x²) + (2x - 4x) + (11 - 7) = 7x² - 2x + 4
