The cost of filling up Jason's car is directly proportional to the number of gallons purchased. It if costs Jason $32.40 to purchase 15 gallons of gas, find the cost of purchasing 20 gallons of gas.
Answer:
$43.2
Step-by-step explanation:
32.4÷15=2.16
2.16×20=43.2
The cost of purchasing 20 gallons of gas will be $43.2.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The costs Jason $32.40 to purchase 15 gallons of gas.
Now,
Let the cost of purchasing 20 gallons of gas = x
Since, The costs Jason $32.40 to purchase 15 gallons of gas.
So, By definition of proportion we get;
⇒ $32.40/15 = x / 20
⇒ 32.40 × 20 / 15 = x
⇒ x = $43.2
Thus, The cost of purchasing 20 gallons of gas = $43.2

Answer:
If m<1 = 38 then m<4 = 38
Step-by-step explanation:
Both of the angles equal 38 degrees. This is true because the angles are vertical, vertical angles are angles opposite each other where two lines cross. Vertical angles are also always congruent, therefore the m<4=38.

Tyler has a bag that contains orange chews, cherry chews, and peach chews. He performs an experiment. Tyler randomly removes a chew from the bag, records the result, and returns the chew to the bag. Tyler performs the experiment 38 times. The results are shown below:
A orange chew was selected 28 times.
A cherry chew was selected 7 times.
A peach chew was selected 3 times.
Based on these results, express the probability that the next chew Tyler removes from the bag will be peach chew as a percent to the nearest whole number.
Answer:
8%
Step-by-step explanation:
Mathematically, the probability of an event can be obtained by dividing the expected number in which event will turn up divided by the total number we have in the sample space
From the question, the total number of times in which the experiment is performed is 38 times
The number of times we have the peach chew selected is 3 times
So the probability that the next removal will be a peach chew will be;
3/38 = 0.079
This as a percent is 7.9%
To the nearest whole number, this figure is 8%

Last year, the seventh-grade enrollment at Main Middle School was 612 students. This year, the enrollment dropped to 489 students due to the opening of a new middle school. Which best reflects the percent change in enrollment at Main Middle School from last year to this year?
Answer:
The percent change in enrollment at Main Middle School was about 20%
Step-by-step explanation:
Percentages
There was a change of enrollments in the 7th grade at Main Middle School from 612 to 489 due to openings of a new school.
The change in the number of enrollments was 612 - 489 = 123.
To express it as a percentage, we divide by the original number and then multiply by 100:
[tex]\displaystyle \mathrm{Change} \% = \frac{123 }{ 612} * 100 \approx 0.2[/tex]
The percent change in enrollment at Main Middle School was about 20%

If the given points in the table lie on a line, then the slope of a line is, 4
What is slope?Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.
So formula for the slope is,
m = change in y coordinate/change in x coordinate = Δy/Δx
Given that,
Coordinates of a point through which line is passing,
X: 1 3 5 7
Y: 2 10 18 26
The slope of a line = ?
The slope of a line can be calculated by finding the rise (difference in the y-values) over the run (difference in the x-values) between two points on the line.
Now, Using the first and last points in the table:
First point- (1, 2)
Second Point- (7, 26)
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope = (26 - 2) / (7 - 1)
= 24 / 6
= 4
The slope of the line is 4.

An airplane descended 345 m in 10 seconds. What was the airplane’s rate of change in elevation? Show your work and don’t forget the unit!
Answer:
The airplane’s rate of change in elevation is 34.5 m/s.
Step-by-step explanation:
Given that,
An airplane descended 345 m in 10 seconds.
We need to find the airplane’s rate of change in elevation. Let the rate is R. Its rate is equal to the distance divided by time. So,
[tex]R=\text{velocity}=\dfrac{345\ m}{10\ s}\\\\=34.5\ m/s[/tex]
So, the airplane’s rate of change in elevation is 34.5 m/s.

If a person was randomly selected, what is the probability that the person selected rock climbing given that the person is female?
Answer:80 % chance
Step-by-step explanation:
The required probability that the person selected rock climbing given that the person is female is 23%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
As mentioned in the question,
Total person in the adventure sports = 100
female rock climbers = 23
The probability that the person selected rock climbing given that the person is female is given as,
= female rock climbers / Total person in the adventure sports
= 23/ 100
= 0.23
Thus, the probability that the person selected rock climbing given that the person is female is 23%.
