Convert 3 qt/min to gallons per hour.
45 gal/h
12 gal/h
180 gal/h
4.5 gal/h
Given:
3 qt/min
To find:
The conversion of 3 qt/min to gallons per hour.
Solution:
We know that,
1 quart = 0.25 gallons
60 minutes = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
Using these conversions, we get
[tex]3 \dfrac{qt}{min}=\dfrac{3\times 0.25}{\dfrac{1}{60}}\ \dfrac{gal}{h}[/tex]
[tex]3 \dfrac{qt}{min}=3\times 60\times 0.25\ \dfrac{gal}{h}[/tex]
[tex]3\ qt/min=45\ gal/h[/tex]
Therefore, the correct option is A.
Snow Crest is 11,508.21 feet higher than Mt. Wilson. Write and solve an equation to find the elevation of Mt. Wilson. Let x represent the elevation of Mt. Wilson. The equation to find the elevation of Mt. Wilson is ____-x=_______. The elevation of Mt. Wilson is _______ feet.
Answer:
16642.1 feets
Step-by-step explanation:
Given :
Elevation of Mt. Wilson = x
If the elevation of snow crest = y
Snow crest = 11,508.21 feet higher than Mt. Wilson
Hence, y = 11,508.21 + x
The elevation of Mt. Wilson, x = y - 11,508.21 feets
From the table, elevation of Snow crest = 28,150.31 feets = y
Hence, The elevation of Mt. Wilson, x = y - 11,508.21 feets
x = 28,150.31 - 11,508.21
x = 16642.1 feets
the equation s = p - 0.15 represents the sale price s of an item with an original price p, after a 15% discount. A T-shirt costs $12. What is the sale price?
Answer:
S = $10.20
Step-by-step explanation:
s = 12 - .15 (12)
s = 12 - 1.80
s = $10.20
If 15% comes off the price, then 85% of the price is left to pay. (100 - 15 = 85)
12 x .85 = $10.20

Gabriella plays video games from 2:49 P.M. To 3:32 P.M. Mason plays video games for 35 minutes. How many minutes longer does Gabriella play video games than Mason? *
Answer:
Mizuki here to help!
8 minutes longer will be the correct answer!
Step-by-step explanation:
First, let's find out how many minutes Gabriella played:
3:32 - 2:49 = 2:92 - 2:49 = 0:43
Check:
2:49 + 0:43 = 2:92 = 3:32
It's correct so...
43 - 35 = 8

In 1846 the depth of the river was 6.7 feet deep. In 1847 it dropped 9%. This year, 1848, it rose 7% What is the depth now.
Answer:
6.5237 feet.
Step-by-step explanation:
initial depth of river H = 6.7 ft
In 1847 it dropped 9%, this means the new depth will be 91% of 6.7
that is (91/100)×6.7 = 6.097 ft
Now in the year , 1848 the depth gain rose by 7%, this means now the new depth 107% of 6.097
= (107/100)×6.097 = 6.5237 feet.
Therefore, new of the depth of river in 1848 = 6.537 ft

Examine the following data set.
{15, 45, 20, 40, 55, 60, 25, 35, 45, 50, 30}
Which piece of data from the data set is an outlier, if there is one?
A) 15
B) 40
C) 60
D) There are no outliers.
The piece of data from the data set is an outlier, if there is one is that there are no outliers. The correct option is D.
What is interquartile range?The interquartile range is a measure of statistical dispersion, or the spread of data, in descriptive statistics.
To identify outliers, we first need to calculate the median and the interquartile range (IQR) of the data set.
The median is the middle value of the data set when it is arranged in order. If there is an even number of values, the median is the average of the two middle values.
First, we arrange the data set in order:
{15, 20, 25, 30, 35, 40, 45, 45, 50, 55, 60}
The median is the middle value, which is 40.
Next, we calculate the IQR, which is the difference between the third quartile (Q3) and the first quartile (Q1) of the data set.
Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set. To calculate Q1 and Q3, we first split the data set into two halves:
Lower half: {15, 20, 25, 30, 35}
Upper half: {40, 45, 45, 50, 55, 60}
Q1 is the median of the lower half, which is 25. Q3 is the median of the upper half, which is 50.
So, the IQR is:
IQR = Q3 - Q1 = 50 - 25 = 25
To identify outliers, we use the following rule: any value that is less than Q1 - 1.5 x IQR or greater than Q3 + 1.5 x IQR is considered an outlier.
Q1 - 1.5 x IQR = 25 - 1.5 x 25 = -12.5
Q3 + 1.5 x IQR = 50 + 1.5 x 25 = 87.5
We see that none of the values in the data set are less than -12.5 or greater than 87.5. Therefore, there are no outliers in this data set.
Thus, the answer is D) There are no outliers.

*40 people responded that they use mouthwash.
*Of the people who use mouthwash, 30 people use floss.
*55 people responded that they do not floss.
*45 people responded that they don't floss and don't use mouthwash
Answer: The image of the completed table is shown below
In the completed table, we have the following values (left to right)
Row One: 30, 10, 40Row Two: 15, 45, 60Row Three: 45, 55, 100==============================================
Explanation:
We're told that "40 people responded that they use mouthwash". That means we'll write "40" at the very end of the "use mouthwash" row. This represents the total number of people who use mouthwash, since we're underneath the "total" in that far right column.
Then we're further told that "Of the people who use mouthwash, 30 people use floss", so we'll write "30" in the first row, first column blank space. These are the people who both floss and use mouthwash. Because earlier we know 40 people use mouthwash overall, this leaves 40-30 = 10 people who use mouthwash, but they don't floss.
To summarize so far: In row 1, we have the following values from left to right: 30, 10, 40
The first two items of this row must add to the last item.
---------------------
Now onto row 2
Since 40 people use mouthwash, and 100 people were surveyed, this means that 100-40 = 60 people do not use mouthwash. The value 60 goes at the very end of row 2. This represents another total.
Like earlier, the first two items must add to the last. So 40+60 = 100.
Now turn to the fact that "45 people responded that they don't floss and don't use mouthwash". This tells us that "45" will be in the "no mouthwash" row and "don't floss" column.
We have 60 people who don't use mouthwash, and 45 of those people also don't floss. Therefore, 60-45 = 15 people do floss but they don't use mouthwash. We'll write "15" in the second row, first column.
Along row 2, we have the following values: 15, 45, 60
----------------------
Row 3
For each column, add up the first two items to get the third one. This will lead to the totals along this bottom row.
Floss: 30+15 = 45Don't Floss: 10+45 = 55 .... note how this matches up with the third piece of information your teacher providedThe third column is already done, but again we can see that 40+60 = 100.
Furthermore, the first two items of the third row add to 45+55 = 100 which helps confirm our answers.
The full completed table is shown below.
------------------------
To summarize, we are effectively just sorting the values given to us to write them into the table. Then we use a bit of algebraic detective work to find out what values are missing so we fill out the completed table.
Write an equation in slope intercept form of the line shown (1,-3) (3,1)
Answer:
y = 2x - 5
Step-by-step explanation:
Using the slope intercept formula y2 - y1 / x2 -x1...
You get a slope of 2 so y = 2x +b
Then to find b the intercept, you plug in one of the coordinates like so...
1 = 2(3) + b
Then solve to get an intercept of -5.
So the slope-intercept form would be...
y = 2x - 5
