Which of the following describes how to calculate net pay? Subtract the total deductions from the net pay. Subtract the total deductions from the net pay. Subtract the total deductions from the gross pay. Subtract the total deductions from the gross pay. Add the total deductions to the gross pay. Add the total deductions to the gross pay. Subtract the total deductions from the take-home pay.
Answer:
(b) Subtract the total deductions from the gross pay
Step-by-step explanation:
The term "net pay" is applied to the pay after deductions are subtracted. It is also called "take-home pay."
The pay computed based on earnings, commissions, credits, and bonuses, before any deductions, is called the "gross pay."
net pay = gross pay - deductions
Net pay is calculated by subtracting total deductions from gross pay.

What is the area of a square if one side is 14 centimeters long?
Answer:
A=a2=142=196cm²
Answer: 196 cm²
hope this helps :)
Answer:
196cm²
Step-by-step explanation:
All of a square's sides are congruent which means if one side is 14cm then all the other sides have to be 14cm as well.
To find the area you multiply the length and the width (A=l*w)
l=14, w=14
14*14=196cm²

Billy purchased $100$ shirts at a cost of $\$15$ each and planned to resell them. The first week he sold some of them for $\$25$ each. The second week he sold the rest for $\$20$ each. If his total profit was $\$600$, how many shirts did he sell the first week?
Answer:
Let the number of shirts he sold the first week = x and the number sold the second week = 100 - x
So we have
[Sales] - [Cost] = Profit
[25x + 20(100 - x)] - [15 * 100] = 600 simplify
25x + 2000 - 20x - 1500 = 600
5x + 500 = 600 subtract 500 from both sides
5x = 100 divide both sides by 5
x = 20 = the number of shirts sold the first week
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
Let x = number of shirts sold in Week 1
Let y = number of shirts sold in Week 2
Profit = Selling price - cost price
If Billy purchased the shirts at a cost of $15 each, then
Week 1: Profit per shirt = $25 - $15 = $10Week 2: Profit per shirt = $20 - $15 = $5Equation 1
Total of 100 shirts purchased:
⇒ x + y = 100
Equation 2
Total profit of $600:
⇒ 10x + 5y = 600
Rewrite Equation 1 to make y the subject:
⇒ y = 100 - x
Substitute this into Equation 2 and solve for x:
⇒ 10x + 5(100 - x) = 600
⇒ 10x + 500 - 5x = 600
⇒ 10x - 5x + 500 = 600
⇒ 5x + 500 = 600
⇒ 5x = 600 - 500
⇒ 5x = 100
⇒ x = 100 ÷ 5
⇒ x = 20
Therefore, Billy sold 20 shirts in his first week.

Answer:
bottom left is the answer
Step-by-step explanation:
Which equation represents the line that passes through the point (4, -5) and is
perpendicular to the line x + 2y = 5?
А
x - 2y = -14
B
x + 2y = -6
C 2x + y = 3
D
2x - y = 13
Answer:
D. 2x - y = 13
Step-by-step explanation:
We are given the line x + 2y =5
We want to find the equation that is perpendicular to this line, and that also passes through (4, -5)
Perpendicular lines have slopes that multiply to -1
First, let's find the slope of the line
The line is currently in standard form (ax+by=c), which doesn't show the slope; we can convert this line into slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)
To do that, we will need to solve the equation for y
Here it is:
x + 2y = 5
Subtract x from both sides
2y = -x + 5
Divide both sides by 2
y = -1/2x + 5/2
The slope of the line is -1/2
Now, to find the slope of the line perpendicular to it, use this equation:
-1/2m = -1
Multiply both sides by -2
m = 2
The slope of the line perpendicular to it is 2
Here is the equation of the line so far in slope-intercept form
y = 2x + b
We need to find b
As the equation passes through the point (4, -5), we can use it to help solve for b.
Substitute 4 as x and -5 as y.
-5 = 2(4) + b
Multiply
-5 = 8 + b
Subtract 8 from both sides
-13 = b
This is our line:
y = 2x - 13
Even though this is in slope-intercept form, all of the options in your question are in standard form. Ergo, we must convert the line into standard form.
To do this, we can subtract 2x from both sides, as in standard form, x and y are on the same side
-2x + y = -13
Now multiply both sides by -1
2x - y = 13
This makes the answer D.

PLEASE HELP ME PASS 8th GRADE
Answer:
61.8 feet to nearest tenth.
Step-by-step explanation:
USING THE PYTHAGORAS THEOREM:
55*2 = 21^2 + h^2 where h is the height of the top of the ladder from the ground.
h^2 = 55^2 - 21^2
= 2584
h = √2584
= 50.83 ft.
So the height of the building
= 11 + 50.83
= 61.83 feet.

Victoria wants to purchase a tablet. She has $130 to spend. She finds one that regularly sells for $139.99 and is on sale of 15% off. Sales tax is 7%. How much will Victoria pay for the tablet? Show your work and record your answer in the red box.
Answer:
$127.32
Step-by-step explanation:
Selling price= $139.99
Sale discount= 15% = $139.99 * 0.15 = $21
Discounted price= $139.99 - $21 = $118.99
Sales tax added= 7% = $118.99 * 0.07 = $8.33
Victoria has to pay = $118.99 + $8.33 = $127.32 so she has enough money to buy it with $2.68 left

Byrn has a stack of photos measuring 12cm wide and 16cm high. He wants to display them on a large rectangular poster in such a way that all photos are equally spaced on each side, including at the edges of the poster, as illustrated (in the attached file)
Q1. Bryn wants to display 9 photos (with longer side vertical) in 3 rows of 3 photos each with 2cm spacing around each photo. What are the dimensions of the poster?
Q2. Bryn wants to display 24 photos (with longer side vertical) with 2cm spacing around each photo. He wants more columns than rows of photos. Find the smallest poster area that is needed.
Q3. Bryn wants to display 18 photos in 3 rows of 6 photos each with 3cm spacing around each photo. The photos may all be displayed in portrait orientation (longer side vertical) or in landscape (longer side horizontal). Which orientation uses the lesser poster area?
Q4. Bryn wants to display 24 photos (with longer side vertical) in 6 rows of 4 photos each with equal spacing around each photo. He has a poster that is 62cm wide and 120cm high. He wants to use the full width of the poster but is prepared to trim some of its height to achieve the equal spacing. How much of the poster does he need to trim?
Please provide working out for all of the answers. Thanks.
The answers for the questions are:
1) The dimensions of poster are 44cm by 56cm
2) The smallest poster area needed is 5328 square centimeter
3) The orientation that uses the lesser poster area is portrait.
4) He needs to trim 4.4cm of the height of poster
What is a rectangle?A rectangle is a quadrilateral with opposite sides equal and all angles 90°
Analysis:
1) since there are 3 photos per row, the spacing for the three photos are 4. Also since there are 3 photos on the column, the spacing would be 4
width of poster = 2x4 + 3x12 = 8 + 36 = 44cm
Height of poster = 4x2 + 3x16 = 56cm
2) possible combinations, are 8 picture on a row and 3 picture on a column
width = 9spacing x 2cm + 8 pictures x 12 = 114cm
length = 4 spacing x 2 + 3pictures x 16 = 56cm
12 pictures on a row and 2 pictures on a column
width = 13 spacing x 2cm + 12 pictures x 12 = 170cm
length = 3 spacing x 2cm + 2 pictures x 16 = 38cm
6 pictures on a row and 4 pictures on a column
width = 7 spacing x 2cm + 6 pictures x 12 = 72cm
length = 5 spacing x 2cm + 4 pictures x 16 = 74cm
The smallest area is 74 x 72 = 5328 square centimeter
3. For portrait,
width = 6 photos x 12cm + 7 spacing x 2cm = 86cm
length = 3 pictures x 16cm + 4 spacing x 2cm = 56cm
For landscape,
width = 6 photos x 16cm + 7spacing x 2cm = 110cm
length = 3 pictures x 12cm + 4 spacing x 2 = 44cm
The lesser poster area is portrait orientation with 86 x 56 = 4816 square centimeter.
4. Let the equal spacing be P
for full width = 62cm
4pictures x 12cm + 5 spacing x P = 62
48 + 5p = 62
5P = 62-48
5P = 14
P = 14/5 = 2.8cm
length of poster using equal spacing of 2.8cm
length would take 6 photos
6 photos x 16 + 7 spacing x 2.8 = 115.6cm
original length of poster is 120cm
so he would need to trim (120-115.6) = 4.4cm
In conclusion, The answers to the questions are:
1) dimensions of poster are 44cm by 56cm
2) The smallest poster area needed is 5328 square centimeter
3) The orientation that uses the lesser poster area is portrait
4) He needs to trim 4.4cm of the height of poster

Step-by-step explanation:
go to x=-4 and see what the y value of the line is
Answer:
1
Step-by-step explanation:
Find the equation of the line. Start with the y-intercept, which is -1. Next find the slope by doing rise/run. To get from (0, -1) to (2, 0) you rise 1 and run 2, so the slope is 1/2.
The equation is y= 1/2x -1.
Plugin 4 for x and solve for y.
y = 1/2(4) -1
y = 2 - 1
y = 1

Answer:
6
Step-by-step explanation:
Write an equation in standard form of the line
With slope 2/5 and going through (-3,6).
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{6})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{\cfrac{2}{5}}(x-\stackrel{x_1}{(-3)})\implies y-6=\cfrac{2}{5}(x+3)[/tex]
[tex]y-6=\cfrac{2}{5}x+\cfrac{6}{5}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y-6)~~ = ~~5\left( \cfrac{2}{5}x+\cfrac{6}{5} \right)}\implies 5y-30~~ = ~~2x+6 \\\\\\ -2x+5y-30=6\implies -2x+5y=36\implies 2x-5y=-36[/tex]
