An athlete runs two miles in 13.5 minutes. How many minutes is this per mile?
Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile

Which is better to buy? 3-yard roll of wrapping paper for $7.02. 8-foot roll of wrapping paper for $7.36
Answer:
3 yard roll of wrapping paper for $7.02 is better to buy.
Step-by-step explanation:
1 yard = 3 foot
3 yard = 9 foot
$7.02 / 9 foot = $0.78/foot
$7.36 / 8 foot = $0.92/foot
0.78 < 0.92
Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.
20/32 x * 25/20
help
Answer:
25/32
Step-by-step explanation:
First you want to simplify the fractions. So, 20/32 would be 5/8, and 25/20 would be 5/4. Next, you want to multiply both the numerator and denominator. So, 5x5 is 25 for the numerator, and 8x4 is 32 for the denominator, leaving you with 25/32 for the answer.
Answer:

If a distribution is skewed to the right with no outliers, which expression is correct?
mean < median
mean ≈ median
mean = median
mean > median
We can’t tell without examining the data.
Answer:
Mean>Median
Step-by-step explanation:
A right skewed distribution with no outliers will have it's mean value greater than the median ( mean > median)
A distribution is said to be right skewed if it's peak is to the left such that it has a long tail to the right.
Conversely, a distribution with it's peak to the right such that it has a long tail is said to be left skewed.
Using the analogy of a boxplot, a right skewed distribution will have it's box to the left and a longer whisker to the right. This means that the median point which is the vertical line in between the box will be lesser than the mean value.
Median < mean = mean > median

The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase to 1.4m. the length of the extra plank of wood that was added is Select one a. 2. 4 b. 1 C. 1.25 d. 1.75V
Answer: Hello There!................
Mean = Sum of observation / total number of observation
Mean = 1.35m
1.35 = Sum of length of 7 wood planks/ 7
1.35*7 = Sum of the length of 7 wood planks
9.45 = Sum of the length of 7 wood planks
Let the length of extra added wood plank = x
So,
(Sum of the length of 7 wood planks + x) / 8 = 1.4m
(9.45 + x) / 8 = 1.4
9.45 + x = 1.4 * 8
9.45 + x = 11.2
x = 11.2- 9.45
= 1.75
So,
The length of extra added wood plank = 1.75m

0.10x + 0.25(24 - x) = 4.50
Answer:
10
Step-by-step explanation:
So you start with
0.10x+0.25(24-x)=4.50
First you do the parenthesis
.25x24 is 6.
So
.10x+6-.25x=4.5
Combine like terms
-.15x+6=4.5
Now isolate the x so you can find what x is
4.5-6
-.15x=-1.5
Then divide
-1.5/-.15
The two negatives make it positive
So 1.5/0.15
Comes to 10.
x=10
The 10 comes like this .15 is 15/100
Simplify that to 3/20
1.5 is 15/10
Simplify that to 3/2
Then divide those
3/2 ÷ 3/20
You cant divide fractions so flip the other side and multiply
3/2 × 20/3
60/6
10
Hope this helps
Answer:
x = 10
Step-by-step explanation:
[tex]0.10x + 0.25(24 - x) = 4.50[/tex]
[tex]0.1x + 6 - 0.25x = 4.5[/tex]

Given are the slopes of several lines. Indicate whether each line is horizontal, vertical, rises from left to right, or falls from left to right.
Answer:
Rises from left to rightVertical LineHorizontal LineFalls from left to rightStep-by-step explanation:
Keep in mind we read graphs from left to right just like how we read and write.
A positive slope will be increase from left to right. A negative slope with decrease left to right. A vertical line will have a undefined slope.A horizontal line will have a slope of 0.We can use those tips to solve the problem.
Option A:
4/5 is a positive slope so it will rise from left to right.
Option B:
No slope automatically means "undefined" so that falls in the definition of a vertical line.
Option C:
A slope of 0 is defined as a horizontal line.
Option D:
-4/5 is a negative slope so it will fall from left to right.

Calculate the straight line distance between the points (-10, -7) and (-8,1).
G.2(B)
Answer:
2√(17) or about 8.2462 units.
Step-by-step explanation:
We want to determine the distance between the two points (-10, -7) and (-8, 1).
We can use the distance formula. Recall that:
[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substitute and evaluate:
[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]
Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.
