A rectangular computer monitor is measured by the length and width of its display resolution. Three different monitors are described below. Monitor A has a display resolution of 640 pixels by 480 pixels. Monitor B has a display resolution of 800 pixels by 600 pixels. Monitor C has a display resolution of 1,280 pixels by 800 pixels. Which of the monitors are similar, based on their display resolution
Answers
Answer: Monitors A and B
Step-by-step explanation:
The similar monitors based on display resolution are those with similar ratios.
Take the ratios to their simplest forms to see which are similar.
Monitor A
= 640 : 480
= 16 : 12
= 4 : 3
Monitor B
= 800 : 600
= 8 : 6
= 4 : 3
Monitor C
= 1,280 : 800
= 32 : 20
= 8 : 5
Monitors A and B are similar as they have the same display ratio.

Describe how the graphs of y = |x| and y = |x| – 15 are related.
A. The graphs have the same shape. The y-intercept of y = |x| is 0, and the x-intercept of the second graph is –15.
B.
The graphs have the same y-intercept. The second graph is steeper than y = |x|.
C. The two graphs are the same.
D. The graphs have the same shape. The y-intercept of y = |x| is 0, and the y-intercept of the second graph is –15.
Answers
Answer:
D is correct
Step-by-step explanation:
A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.
"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.

Maureen spends four times as long riding the train each day as riding the bus. If she spends 75 minutes on the bus and the train all together, how long did she spend riding the train
Answers
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Set x as the amount of time she spends riding the bus
75 = time on bus + time on train
She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x
75 = x + 4x
75 = 5x
x = 15 minutes on the bus
Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour

What is the number that when you multiply by 2 and add 7 to the product you get is 10.8 pls answer
Answers
Answer:
1.9
Step-by-step explanation:
2x+7=10.8
2x=3.8
x=1.9
1.9x2=3.8+7=10.8
The required number is 1.9, when multiply by 2 and add 7 to the product gives 10.8.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
let the number be x,
According to the question,
2x + 7 = 10.8
Simplifying the above expression,
2x = 10.8 - 7
2x = 3.8
x = 1.9
Thus, the required simplified value of the given equation model is 1.9.

Solve the formula V = s²h for s.
Answers
Answer: [tex]s=\sqrt{Vh}[/tex]
Step-by-step explanation:
[tex]V = s^2h\\[/tex]
divide both sides by h to isolate s
[tex]Vh=s^2[/tex]
since s is squared, square root both sides to make s not squared
[tex]\sqrt{Vh}=\sqrt{s^2}[/tex]
Vh isn't a numerical value so no need to simplify anything just leave everything as is, so you should get:

The wholesale cost of a bicycle is $98.75.
The markup for the bicycle is 33.3%. Find
the selling price of the blcycle. Round to
the nearest cent. (Answer please)
Answers
Answer:
$131.60
Step-by-step explanation:
For the promotion, markup is 33.3% of the selling price.
Now, Selling Price = Cost price + Cost price*Markup
Selling Price = $98.75 + $98.75*33.3%
Selling Price = $98.75 + $32.88375
Selling Price = $131.63375
Selling Price = $131.60
Thus, the selling price of the bicycle after calculating the markup is $131.60.

Step 1: Define equation
n/-5 = 7
Step 2: Solve for n
Multiply both sides by -5: n = -35Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -35/-5 = 7Divide: 7 = 7Here we see that 7 does indeed equal 7.

Adsila and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes, Adsila fills 11 boxes every hour. How many boxes does Carlos fill every hour?
Answers
Answer:
Carlos fills 16 boxes per hour.
Step-by-step explanation:
Given that:
Adsila and Carlos are working together to fill the gift boxes for soldiers.
Number of boxes filled while working together in 4 hours = 108 boxes
Number of boxes filled while working together in 1 hour = [tex]\frac{108}{4} = 27[/tex] boxes per hour
Number of boxes filled by Adsila every hour = 11 boxes
To find:
Number of boxes filled by Carlos every hour = ?
Solution:
Number of boxes filled every hour while working together = Number of boxes filled every hour by Adsila + Number of boxes filled every hour by Carlos
Number of boxes filled every hour while working together = 27 = 11 + Number of boxes filled every hour by Carlos
Number of boxes filled every hour by Carlos = 27 - 11 = 16

Examine the following table, which represents some points on a line.

What is the equation for the line in slope-intercept form?
Answers
Let the points represented by the given points on a line .
We well know the equation of the line.
So equation of the line is,
y = mx+b.
Where m= slope of the line
b= y intercept.
Now, let the points lying on the line are
(0,-2) nad (3,-3).
We know that ,
Slope of the line 'm' = (y2-y1)/(x2-x1).
m=-2-(-3)/0-3
m=-2+3/0-3
m= 1/-3.
y intercept 'b' = (-2).
Then , equation of the line is
