Answer: OPTION A
Step-by-step explanation:
The distance between any number is always positive so we should apply the absolute value.
The distance between numbers=number 1-number2 (or vise versa, and that is why we need absolute value)
In your question, the two numbers are 3/4 and 2. Applying to the expression above, the distance between two numbers should be |3/4-2| or |2-3/4|.
The only option in your case is |3/4-2| and this is it.

Step-by-step explanation:
a car manufacturer claims that their car can get 32 miles per gallon minus the speed factor. thus caj be modeled by linear equatioj f (×) =33 -015x where f(×) represents the miles per gallon and x is the mph . what would be the predicted miles per gallon for a car going 60 mph using this equation?
Answer:
f(x) = 24 miles per gallon
Step-by-step explanation:
car manufacturer claims that their car can get 33 miles per gallon minus the speed factor
f (×) =33 -0.15x
For a car going 60 mph
f (×) =33 -0.15x
X=60 mph
f (×) =33 -0.15x
f(x) = 33-0.15(60)
f(x) = 33-9
f(x) = 24 miles per gallon

The dimensions of a rectangular bin are consecutive integers. If the volume of the bin is 4896 cubic inches, what are the dimensions of the bin? a. 12 x 18 x 24 c. 15 x 17 x 19 b. 16 x 17 x 18 d. 17 x 18 x 19
Let's use an equation to solve this problem.
Since they are consecutive integers, if we say that the first number is [tex]x[/tex], then the next two numbers (three dimensions in a rectangular prism) are [tex]x+1[/tex] and [tex]x+2[/tex] respectively.
[tex]x*(x+1)*(x+2)=4896[/tex]

2x20
2х2х2×5
2x2x4x5
Answer:
2x2x2x5 is your answer
Step-by-step explanation:
40 is a composite number. 40 = 1 x 40, 2 x 20, 4 x 10, or 5 x 8. Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40. Prime factorization: 40 = 2 x 2 x 2 x 5, which can also be written 2³ x 5.

Answer:
both same if we see. the one inch also costs l dollar wheras 10 dollar costs 10 inch. ok
Answer:
10in pizza
Step-by-step explanation:
We need to find the area of each pizza.
A = [tex]\pi[/tex][tex]r^{2}[/tex]
radius is 1/2 the diameter.
1in pizza 10in pizza
A = [tex]\pi[/tex]([tex].5^{2}[/tex]) A = [tex]\pi (2.5^{2} )[/tex]
A = .25[tex]\pi[/tex] A = 6.25[tex]\pi[/tex]
A = .79 A = 19.63
19.63/10 for [tex]in^{2}[/tex] per $1
So the 1in pizza bite is $1 for .79[tex]in^{2}[/tex] and we can see from the 10in pizza it's $1 for 1.96[tex]in^{2}[/tex]. So it is much better to get the 10in pizza.

I enter the garden. There are 34 people. You hug 30. How many people are in the garden.
Answer:
34
Step-by-step explanation:
There are 34 people in the garden prior to the time I joined them.
So when I entered the garden, the total number of people in the garden will be:
34 + 1 = 35 peopleLet assume, you as the reader was part of the people in the garden and you hugged 30 people. That doesn't add up or increase the number of people in the garden.
At the end of the day, the number of people you did not hug is:
35 - 30 - 1(you)
= 35 - 31
= 4 people
Therefore, we can conclude that there are 35 people present in the garden.

miranda made some cupcakes for the school bake sale. Of the cupcakes 1/2 are choclate and 1/2 are strawberry. Of the strawberry cupcakes, 1/3 are frosted with vanilla frosting, and the rest are frosted with choclate frosting. What portion of the cupcakes are strawberry with chocalate frosting? I also need to be quick and show work
Answer:
2/3
Step-by-step explanation:
half are choclate so the rest is 50% and 1/3 is vanilla so 2/3 are strawberry and chocolate
1/3 portion of the cupcakes are strawberry with chocolate frosting.
What is portion?An individual part or share of something is called as portion.
It also refers to the divide something into parts.
Now it is given that,
Portion of chocolate cupcakes = 1/2
Portion of strawberry cupcakes = 1/2
Of the strawberry cupcakes.
frosted with vanilla frosting = 1/3
frosted with chocolate frosting = 1-1/3 = 2/3
Since, 1/2 portion of all the cupcakes are strawberry cakes and out of 1/2, 1/3 are frosted with vanilla frosting and 2/3 are frosted with chocolate frosting.
strawberry cupcakes frosted with chocolate frosting = 2/3 of 1/2 = 2/6
⇒strawberry cupcakes frosted with chocolate frosting = 1/3
Hence,1/3 portion of the cupcakes are strawberry with chocolate frosting.

Caleb brought groceries and paid $1.60 in sales tax. The sales tax rate is 2.5%. What was the price of caleb’s groceries, before tax?
Answer:
$64
Step-by-step explanation:
We can set up a percentage proportion to find the value Caleb's groceries before tax.
[tex]\frac{1.60}{x} = \frac{2.5}{100}[/tex]
We can cross multiply to find the value of x.
[tex]100\cdot1.60=160\\\\160\div2.5=64[/tex]
So the original cost before tax was $64.
Hope this helped!
Answer:
$1.64
Step-by-step explanation:
We need to find the before tax price so let that be x
100-2.5% = 97.5% (since this is the reduction before the sale)
Turn this percentage into a decimal so 0.975
To find x we must remember this price multiples 0.975 to give us $1.60
x * 0.975 = 1.60
x = 1.60 / 0.975
x = 1.64 (2dp)

"Tamara runs 5 miles each week"
Let Tamara runs 'x' weeks then equation that represents the total distance covered by Tamara will be,
1). y = 5x
2). Here 'y' is directly proportional to the number of weeks 'x'.
3). And the graph when plotted will start from 0. Therefore, graph (1) will be the graph for the given equation.
"Tamara runs 5 minutes more than she walks each day."
1). If Tamara walks 'x' minutes daily and she runs for y minutes then relation between x and y will be,
y = x + 5

The golfer with the highest score in a tournament was nine over par. The golfer with the lowest was five below par. What was the range in golf scores?
Answer: The range in golf scores was 14.
Step-by-step explanation:
Range = Maximum - minimum
Values above some limit are represented by positive integers whereas values blow a certain limit is represented by negative numbers.
Given: The golfer with the highest score in a tournament was nine over par i.e. (9). The golfer with the lowest was five below par i.e. (-5 ).
So, the range in golf scores = 9-(-5)
= 9+5
= 14
Therefore, the range in golf scores was 14.

In the 1970s, due to world events, there was a gasoline shortage in the United States. There were often long lines of cars waiting at gas stations. Part A: If there were 41 cars in a line that stretched 388 feet, what is the average car length? Assume that the cars are lined up bumper-to-bumper. Round your answer to the nearest tenth of a foot.
Answer:
Part A: The average car length is 9.1 feet to the nearest tenth foot
Part B: The line would be 9100 feet to contained 1000 cars
Step-by-step explanation:
* Lets explain how to solve the problem
# Part A:
- There were 62 cars in a line that stretched 567 feet
- The cars are lined up bumper-to-bumper
- That means there is no empty spaces between the cars
* To find the average length of the car we will divide the length of
the line by the numbers of the cars
∵ The average car length = length of the line/number of cars
∵ The length of the line is 567 feet
∵ The numbers of the cars is 62 cars
∴ The average car length = 567/62 = 9.1 feet
* The average car length is 9.1 feet to the nearest tenth foot
# Part B:
- There are 1000 cars
- We need to find the length of line which contained the cars
∵ The average car length = length of the line/number of cars
∵ The average of car length is 9.1 feet
∵ The number of the cars is 1000 cars
∴ 9.1 = length of the line/1000
- Multiply both sides by 1000
∴ The length of the line = 9.1 × 1000 = 9100 feet
∴ The line would be 9100 feet to contained 1000 cars
2. If x¹¹+101 is divided by x + 1, then what remainder do we get?

So if this is divided by x+1, it means that we can write
[tex]x^{11}+101=(x+1)P(x)+R\\\\so \ for \ x = -1\\\\(-1)^{11}+101=100=0*P(-1)+R=R\\\\\text{So the remainder is 100 !!}[/tex]

1. Explain the process for combining like terms for 12x - 3y + 8 - 5x + 4y
Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]
7x+y+8
