Person A spends $9.80 on gas. The car drives 27 miles per gallon and the driver drives 135 miles.
Person B's car gets 29 miles per gallon and spends $14.28 on gas to drive 203 miles.
If person A spends $13.72 on gas at the same rate, and person B spends $16.32 on gas, what is the difference in the amount of miles the cars can travel before running out of gas?

Answer:
i dont know what to say, bro
Step-by-step explanation:
just kidding $72.52
Step-by-step explanation:
A gallon of gasoline costs $2.96.
Your car can travel the distance on each gallon of gasoline = 28.8 miles
Your length of the trip = miles =
First we calculate the total use of gasoline on the trip.
∵ By 1 gallon gas of gasoline you can cover the distance = 28.8 miles
∴ to take miles trip gasoline used =
=
=
= 24.5 gallons
Since the cost of one gallon gasoline = $2.96
∴ The cost of 24.5 gallons of gasoline = 24.5 × 2.96
= $72.52
You spend $72.52 on gasoline for the trip of miles.

Answer:
1A. Half jump
1B. 2/3 is half of 4/3
2. 4
Step-by-step explanation:
1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.
1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.
2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)
A, K, and L have a total of $159. A has $11 more than K. L has twice as much money as K. How much money does L have?

Help me!! im stuck and please help me with range
Answer:9
Step-by-step explanation:
The range is the simplest measurement of the difference between values in a data set. To find the range, simply subtract the lowest value from the greatest value, ignoring the others.
Your answer, in this case, is 9. If your largest number is 10 and the smallest is 1.
10-1=9
Answer:
9
Step-by-step explanation:
The range is the simplest measurement of the difference between values in a data set. So 10-1 is 9

water drains out of the bathtub at a rate of 5 gallons in 2 1/4 minutes. how much water drains out of the tub each minute?
Answer:
[tex]2~2/9[/tex] gallons per minute
Step-by-step explanation:
If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.
We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!
The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].
So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.
The quantity of water that drains out of the tub each minute is 2.23 gallons.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.
2¹/₄ minuts = 5 gallons
1 minute = 5 / 2¹/₄
1 minute = 5 /2.25
1 minute = 2.23 gallons
Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

Find the distance between -2 3/5 and -1 on a number line, Write the answer as a mixed number.
Answer:
-3 3/5
Step-by-step explanation:
-1 can also be written as -1/1
the lowest common denominator is 5 so re write the as 3/5 - 5/5
-3/5 - 5/5 = -8/5 = -1 3/5
-2 - 1 3/5 = -3 3/5
The distance between the numbers -2(³/₅) and -1 will be -3³/₅.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."
It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
The distance will be calculated as;-
-1 can also be written as -1/1 the lowest common denominator is 5 so rewrite the as 3/5 - 5/5
-3/5 - 5/5 = -8/5 = -1³/₅
-2 - 1³/₅= -3³/₅
Therefore, the distance between the numbers -2(³/₅) and -1 will be -3³/₅.

What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box.
Answer:
y = 2x + 2
Step-by-step explanation:
As we know, slope intercept is: y = mx + b
m is slope and b is the y-intercept.
Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.

In ΔOPQ, \overline{OQ} OQ is extended through point Q to point R, \text{m}\angle PQR = (4x-10)^{\circ}m∠PQR=(4x−10) ∘ , \text{m}\angle OPQ = (x+9)^{\circ}m∠OPQ=(x+9) ∘ , and \text{m}\angle QOP = (x-5)^{\circ}m∠QOP=(x−5) ∘ . Find \text{m}\angle PQR.m∠PQR.
Answer:
In
In to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\a
Step-by-step explanation:
The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length thus m∠PQR will be 18°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In any triangle,The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length.
In the given triangle below image,
m∠PQR = m∠OPQ + m∠POQ
4x - 10 = x + 9 + x - 5
4x - 10 = 2x + 4
2x = 14
x = 7
So,
m∠PQR = 4(7) - 10 = 18°
Hence "The measure of m∠PQR will be 18° for the given triangle".

This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?
Answer:
28650
Step-by-step explanation:
just subtract 59,466-30,816
The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people
How many more people live in Cheyenne than in Laramie?Population can be defined as the total number of people living in a particular geographical location at a period of time.
Population of Cheyenne = 59,466
Population of Laramie = 30, 816
The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie
= 59,466 - 30, 816
= 28,650 people
Hence, 28,650 more people live in Cheyenne than in Laramie.
