Tatiana [17]

Since drapes have to be covered all over the window and the beneath of the window, both lengths have to be added.

Find the taxable income of a married couple with two children, who have a combined income of $75,000.

Dima020 [189]

Answer:

$47,200

Step-by-step explanation:

Given :

The total income of a married couple = $75,000.

Number of children = 2

Therefore to find the taxable income of a U.S. family is given by the following formula ---

taxable income = total income- exemption deduction - standard deduction

We know that exemption deduction for a U.S couple as fixed by the government is $15,600.

And the standard deduction for a U.S couple as fixed by the government is $12,200.

Thus in order to find the taxable income of the couple, use the formula

taxable income = total income- exemption deduction - standard deduction

= $75,000 - $15,600 - $12,200

= $47,200.

Thus the taxable income is $47,200.

Can someone help me

Deffense [45]

Answer:

w = 10 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = $\frac{1}{2}$ base × height

here base = 6 and height = 8, thus

A = 0.5 × 6 × 8 = 3 × 8 = 24 cm²

The area of the rectangle = 5 × 24 = 120 cm²

area of rectangle = lw ( l is length, w is width )

Here l = 12, thus

120 = 12w ( divide both sides by 12 )

w = 10 cm

Maria want to make a footstool in the shape of a cylinder, as show below. She wants to fill the footstool with foam and cover it

dexar [7]

Answer:

She'll need 8143 cubic inches of foam and 1,809.6 square inches of fabric.

Step-by-step explanation:

Assuming you want to know how much foam and fabric she will need...

First the foam... so we need to determine the volume of that footstool. The Volume of a cylinder is given by:

V = π * r² * h

So, we plug in the numbers:

V = π * 12² * 18 = π * 144 * 18

V = 2,592 π = 8143 cubic inches.

Now for the fabric... we'll assume Maria wants to cover the side of the stool and the top, but not the bottom.

The side of the stool is basically a rectangle of width of 18 inches and a length of the circumference of the base of the stool. The circumference is given by: C = 2 π * r of course, so C = 24π = 75.14 inches.

So the lateral surface of the cylinder is:

LS = 18 * 75.14 = 1,357.2 sq inches.

Then we need to calculate the area of the top... which is easy:

A = π * r² = π * 12² = 144 π = 452.4 sq inches

So, to cover the lateral side of the footstool and its top, she needs to use:

TA = 1,357.2 + 452.4 = 1,809.6 sq inches of fabric.
