What is the position of C on the number line below?
Write your answer as a fraction or mixed number.
Answer:
2/5
Step-by-step explanation:
there are 5 lines starting at point 1 and ending at 2. point c is on the second line which makes it 2/5ths
The position of C on the number line below is 7/5 or 1 2/5.
What is the number line?The number line is a horizontal line where all the integers are placed at equal intervals. The number line is extended to infinity on both sides.
Also, the line segment between two integers also divided into subparts to represent the rational number.
here given in the number line there are two integers 1 and 2 in which point C is situated.
The line segment between 1 and 2 is divided into 5 parts.
every subpart in line segment between 1 and 2 will be= the length of the subpart / total number of division
= (2-1)/5= 1/5
C point is present at a distance of 2 subparts from integer 1.
So the position of C will be = 1+(2)(1/5)= 1+(2/5)= 7/5 or 1 2/5
Therefore The position of C on the number line below is 7/5 or 1 2/5.

At a local car wash Josh can vacuum 3 cars in 17 minutes. How many cars can he vacuum in an hour?
Answer:
10 cars
Step-by-step explanation:
he can vacuum 3 cars in 17 minutes
so in 1 hour its (60/17) x 3
Or you can do 17/3 for how long it takes to clean 1 car
then divide 60 by that number, you round down for both since you don't complete the car if its a decimal
A restaurant earns $10 for each hour worked up to 40 hours each week and 15 for each additional hour worked over 40 hours. If x represents the total number of hours the restaurant host work,which function,f(x), represent the total amount the restaurant host would earn if working for more than 40 hours
Answer:
[tex]f(x) = 15x - 200[/tex]
Step-by-step explanation:
Given
[tex]Earnings = \$10[/tex] per hour for 40 hours, weekly
[tex]Additional\ Hour = \$15[/tex] per hour over 40 hours, weekly
Required
Determine f(x)
From the question, we have that
x represents hours worked
Earnings in 40 hours is: 40 * 10 = $400
Hours over 40 will be: x - 40
So, earnings during this time will be: (x - 40) * 15
Total earnings is:
[tex]f(x) = 400 + (x - 40) * 15[/tex]
[tex]f(x) = 400 + 15x - 600[/tex]
[tex]f(x) = 15x - 600 + 400[/tex]
[tex]f(x) = 15x - 200[/tex]

After a parade, a group of volunteers is helping to pick up the trash along a 2-mile stretch of a road. The group decides to divide the length of the road so that each volunteer is responsible for cleaning up equal-length sections. Find the length of a road section for each volunteer if there are 8 volunteers
Answer: 0.25 miles
Step-by-step explanation:
When solving a word question, look for certain words that tell you what you should be solving for, and how to solve it.
In this problem, the group DIVIDES the length of the road EQUALLY, which tells you that in order to solve the problem, you must divide the length of the road by the number of volunteers.
The road is 2 miles long, and there are 8 volunteers, so
8/2 = 0.25
Thus, each person must clean 0.25 miles of road.
Using proportions, it is found that the length of road section for each volunteer will be of 0.25 miles.
-----------------------
This question is solved by proportions, using a rule of three to find the length of the road assigned to each volunteer, as each volunteers will be assigned an equal length of the road.In total, the length of the road is of 2 miles. Thus, 8 volunteers are responsible for 2 miles. For how many miles will a single volunteer be responsible?-----------------------
The rule of three is given by:
8 volunteers - 2 miles.
1 volunteer - x miles
Applying cross multiplication:
[tex]8x = 2[/tex]
[tex]x = \frac{2}{8}[/tex]
[tex]x = \frac{1}{4}[/tex]
[tex]x = 0.25[/tex]
The length of road section for each volunteer will be of 0.25 miles.

If 2.2 pounds of a certain grain cost $1.54, how much will 5.7 pounds of the grain cost? A. $4.38
B. $4.79
C. $3.62
D. $3.99
The cost of 5.7 pounds of the grain is given by the proportion A = $ 3.99
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
We can use a proportion to solve this problem. Let "A" be the cost of 5.7 pounds of the grain. Then we can write:
2.2 pounds / $ 1.54 = 5.7 pounds / A
To solve for "A", we can cross-multiply and simplify:
2.2 pounds x A = $ 1.54 x 5.7 pounds
A = ($ 1.54 x 5.7 pounds) / 2.2 pounds
A = $ 3.99
Hence , 5.7 pounds of the grain will cost $ 3.99

Write an equation in slope-intercept form of the line shown. y 4 (0, 3) (4, 2) 2 2 4 x
Answer:
The slope intercept form of (0,3) and (4,2) is y= -1/4x+3
Step-by-step explanation:
The distance from our y values from 3 to 2 is -1.
The distance from our x values is 4.
We can put these values as our slope and we know that the Y values are always rise and the x values are always run
Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.
