First let's review how to find the surface area of a rectangular prism. Since the opposite faces have the same area, we just need to find one of each pair of faces and multiply the result by 2.

One face in each pairs adds up to 6*4+2*4+2*6=24+8+12=44

Now we just need to multiply this by 2!

44*2=88 cm^2

I really hope my explanation helped, if there are any more question about this please ask me in the comments I will answer them.

Ebony's gross income is $46 660 with allowable tax deductions of $4120. a What is Ebony's taxable income? b Calculate the amount
jasenka [17]

Answer:

(a) Ebony's taxable income = $42,540

(b) Amount of tax due = $5190.3

(c) Amount of tax owed = $4810.3

Step-by-step explanation:

Ebony's gross income = $46,660 (given)

Allowable tax deductions = $4,120 (given)

(a) Taxable Income = Gross income - Tax deductions

Ebony's taxable income = $46,660 - $4,120

Ebony's taxable income = $42,540

(b) Amount of tax due = 22% of Taxable Income,

Refer to the USA Tax Brackets for 2019 (See Attached image)

Amount of tax due = 10% on first $9,700 + 12% on ($39475-$9700) + 22% on  ($42540-$39475).

Amount of tax due = 10% on first $9,700 + 12% on $29775 + 22% on $3065.

Amount of tax due = $970 + $3573 + $647.3

Amount of tax due = $5190.3

(c) Ebony pays $95 per week in tax. In four weeks (a month), she'd pay

$95 * 4 = $380

Amount of tax owed = Amount of tax due - Amount of tax paid

Amount of tax owed = $5190.3 - $380 = $4810.3

I need ANSWERS for 13-14 please

230 per hour. multiply 230 by the number of hours to find total posters.

The equation is Total = 230 x hours written as T = 230x, where x is the number of hours.

you have the total, so replace t with the value and solve for x:

1265 = 230x

Divide both sides by 230:

x = 1265 / 230

x = 5.5 hours.

14.

Mean is the average. To find the average, add the four scores together and divide by 4.

The expression is Mean = ( score 1 + score 2 + score 3 + score 4)/4

Replace what is known:

20 = (25 + 15 + 18 + p)/4

Simpligy:

20 = (58 +p) /4

Multiply both sides by 4:

80 = 58 + p

Subtract 58 from both sides:

p = 80 - 58

p = 22
