-6-1=-7, so; -3x-7Rachel drove 140 miles on 5 gallons of gas. At this rate, how far could she drive on 9 gallons of gas?
Answer: 252 miles on nine gallons of gas.
Step-by-step explanation:
Find how many miles Rachel can travel on 1 gallon of gas by dividing 140 by 5 to get 28.
After getting 28, multiply it by 9 to get 252.
Therefore, Rachel, on nine gallons of gas, can travel 252 miles.

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
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.
Write an equation for the nth term of each arithmetic sequence. Then find the 12th term of the sequence.
as = 14, d = -3
We need to know about arithmetic sequence to solve this problem. The equation for the nth term of each arithmetic sequence is a+(n-1)d and the 12th term of the sequence is -19.
An arithmetic sequence is a sequence of numbers where the difference between consecutive numbers is constant. If a,b and c are in arithmetic sequence then we can say that 2b=a+c. If the starting value of an arithmetic sequence is a and the difference between every consecutive number is d, then we can write the second number as a+d, the third as a+2d and so on. So for the nth term of an arithmetic sequence the equation is
nth term=a+(n-1)d where a is the starting value, d is the constant difference
We have been given the value of a and d, a=14 and d=-3, we need to find the value of the 12th term of the sequence.
12th term= a+(n-1)d= 14+(12-1)x(-3)=14-33=-19
Therefore we found out using the concept of arithmetic sequence that the equation for the nth term is a+(n-1)d and the 12th term of the sequence is -19.

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
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

probability is the department of mathematics regarding numerical descriptions of ways probably an event is to occur, or how in all likelihood it is that a proposition is genuine. The opportunity of an occasion is various among zero and 1, where, more or less speakme, zero indicates impossibility of the event and 1 suggests truth

Multiple Choice
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.
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.

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)
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.

Solve the formula V = s²h for s.
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:
[tex]s=\sqrt{Vh}[/tex]

Bob and Alice have designed and created a website for their high school. The first week they had 5 visitors to the site; the second week, they had 10 visitors; and during the third week, they had 20 visitors. If the trend continues, how many visitors can they expect in the fifth week? Explain your answer.
Answer:
80 visitors
Step-by-step explanation:
From the above question, we can see that:
The trend is explained using geometric sequence
The formula for Geometric sequence is given as:
an = ar ^n - 1
Where a = first term
r = common ratio
n = number of terms
an = nth term
From the above question, let the number of term be equal to the number of weeks.
First week = First term = 5
Second week = Second term = 10
Third week = Third term = 20
Common ratio = a2/a1 = a3/a2 = 10/5 = 20/10 = 2
We are to find the number of visitors for the Fifth week = fifth term,
Hence:
a5 = 5 × 2^5 - 1
a5 = 5 × 2^4
a5 = 80 visitors
The number of visitors we can expect for the fifth week = 80 visitors

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?
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
