Answer:
56 mph
Step-by-step explanation:
Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84
Answer:
56
Step-by-step explanation:
84 / 1.5 = 56

Answer:
Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.
Find and compare the means to the nearest tenth.
7th-grade mean:
✔ 16
5th-grade mean:
✔ 13.4
What is the relationship between the means?
✔ The 7th-grade mean is about 2.5 points higher.
Step-by-step explanation:
Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.
What is the Mean of a Data Distribution?The mean is the average of the data set, that is the sum of each data value divided by the number of data points.
Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.
Mean for 7th Grade Students:
Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21
Mean = 335/21
Mean = 15.95 = 16
Mean for 5th Grade Students:
Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19
Mean = 281/21
Mean = 13.38 = 13.4
The difference between their means = 16 - 13.4 = 2.6.
Hence, Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

The scatterplot below shows the relationship between the number of gallons of gasoline in the tanks of 14 cars, and the maximum number of miles the cars can be driven on the given amount of gasoline.
Gasoline
A graph has gallons in gas tank on the x-axis and maximum miles on the y-axis. A line goes through points (9, 280) and (12, 360).
Based on the data collected, which combination of gallons in the gas tank and maximum number of miles seems most likely to be possible?

B.9 gallons in the gas tank and 280 miles.
From the given figure we see that the line of best fit passes through the point (13,400) and (17,520)
We know that the equation of a line passing through two point (a,b) and (c,d) is calculated by using the formula
y - b = d-b/c-a x (x-a)
Here we have:
(a,b)=(13,400) and (c,d)=(17,520)
Hence, the equation of line of best fit is: y - 400 = 520 - 400/17-3 x (x - 13)
y-400=120/4 x (x-13)
y=400=30x(x-13)
y-400=30x-390
y=30x-390+400

0 gallons in the gas tank and 20 miles
when x=0 we have:
y=10≠20
Hence, option: A is incorrect.
B)
9 gallons in the gas tank and 280 miles .
when x=9 we have:
y=30×9+10
y=280
Hence, option: B is correct.
C)
11 gallons in the gas tank and 360 miles
when x=11; we have:
y=30×11+10
y=340≠360
Hence, option: C is incorrect.
D)
19 gallons in the gas tank and 520 miles
when x=19; we have:
y=30×19+10
y=580≠520
Hence, option: D is incorrect.

The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. The adult tickets sold for $7.50 each and the student tickets sold for $4.50 each. If the junior class collected $2,212.50 in ticket sales, how many student tickets did the class sell
**No answer choices, please explain how you got the answer cause I have no clue how to do this**
❤❤
Answer: I believe this is correct, i got 80 tickets
Step-by-step explanation:
I divided 2212.50 by the adult tickets, 7.50, and got 295. if the adults sold 295 tickets, then the students would have sold 80, because thats all that were left. I hope I helped
The number of student tickets the class sold is 200.
Let
x = number of student ticket sold
y = number of adult ticket sold
The junior class at Summerfield High School sold a total of 375 tickets for their spring festival. Therefore,
Total tickets:x + y = 375The junior class collected $2,212.50 in ticket sales. Therefore,
Total sold:4.50x + 7.50y = 2212.50Combine the equation to get the number of student ticket sales.
x + y = 375
4.50x + 7.50y = 2212.50
Multiply equation(i) by 4.50x
4.50x + 4.50y = 1687.5
4.50x + 7.50y = 2212.50
3y = 525
y = 525 / 3
y = 175
x + y = 375
x = 375 - 175
x = 200

Two vertical angles form a linear pair.
A. Always True
B. True in some cases
C. Always False
PLEASE ONLY ANSWER THIS QUESTION IF YOU 100% KNOW YOU HAVE THE ANSWER CORRECT!!!!
Answer: C) Always false
====================================================
Explanation:
A linear pair of angles satisfy these two requirements (both must be true)
The angles are adjacentThe angles are supplementary, ie they add to 180.While it is possible for vertical angles to be supplementary (they both are 90), it is not possible for vertical angles to be adjacent. This is because vertical angles do not share a common side. Vertical angles are opposite one another, so they are as far from adjacent as possible, while still sharing a common vertex point however.
This means that vertical angles are never considered to be a linear pair. Put another way, you can ask yourself "can vertical angles form a straight line?". The answer is "they can never form a straight line". Again the fact they aren't adjacent is the reason why.

Answer:
72%
Step-by-step explanation:
18/25 = 0.72
0.72 x 100 = 72
Answer:
72%
Step-by-step explanation:
Step 1 we make the assumption that 25 is 100% since it is our output value
Step 2 we next represent the value we seek with x
Step 3 from step 1, follows that 100%=25
Step 4 in the same vein, x%=18
Step 5 this gives us a pair of simple equations: 100% = 25(1)
X%= 18(2)
Step 7: taking inverse of both sides yields
X%\100% = 18/25
—> = 72%
Therefore, 18 is 72% of 25
