Is (5, 1) a solution to this system of equations? x + 15y = 9 20x + 7y = 20

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 :)

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

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

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]

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]
