Percent counts the number of a quantity compared to another quantity's 100 amount. The amount each person would pay is given by: Option D: $9. 75
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case,
Bill for lunch = $32.50
Tip = 20% of bill = [tex]\dfrac{32.50}{100} \times 20 = \dfrac{32.50}{5} = 6.50[/tex] (in dollars)
Total amount = Bill + Tip = $39
This amount has to be divided in 4 equal part.
Thus, each part of those 4 parts would be [tex]\dfrac{39}{4} = 9.75[/tex] (in dollars).
Thus, the amount each person would pay is given by: Option D: $9. 75

-5/6,-4/3 which is greater
Answer:
-5/6
Step-by-step explanation:
To figure out which one is greater, we need to convert them so they have a common denominator:
You can do this two ways, because 6 is a multiple of 3, we can just multiply the second fraction by 2:
[tex]\frac{-4}{3} \\[/tex] x 2 = [tex]\frac{-8}{6} \\[/tex]
[tex]\frac{-5}{6}[/tex]
The second way is multiplying both the fractions so they have a common denominator.
[tex]\frac{-5}{6} = \frac{-15}{18}[/tex]
[tex]\frac{-4}{3} = \frac{-24}{18}[/tex]
Because the numbers are negative, -15 is the greater number.
Therefore, [tex]\frac{-5}{6}[/tex] is the greater fraction.
find the volume and height
Answer:
h = 11
Step-by-step explanation:
to find h
5² + h² = 12²
25 + h² = 144
h² = 144 - 25
h² = 119
h = 11
Last week, you watched 4 hours of TV. This week, you watched 8 hours of TV.
Place points on the graph to show your activity for last week and this week
Answer:
You decide that you will spend 2 times as many hours outdoors as you spend watching TV.
Let the hours spent outdoors be = o
Let the time spent on watching tv be = t
So, general equation becomes o=2to=2t
Last week, you watched 4 hours of TV. This week, you watched 8 hours of TV.
When t = 4
o = 2(4) = 8 hours
When t = 8
o = 2(8) = 16 hours
We have been asked to place points on the graph to show your activity for last week and this week.
Please find attached the points display.
hope it helps.A slice is made perpendicular to the base of a right rectangular pyramid through the vertex. What is the area of the resulting two-dimensional cross section? Enter you answer in the box.
Area is a measure of space occupied in 2 dimensions. The area of the considered two dimensional cross section is:
[tex]\dfrac{1}{2}L.h \: \rm unit^2[/tex] (if cross section is with respect to length)[tex]\dfrac{1}{2}W.h \: \rm unit^2[/tex] (if cross section is with respect to width)[tex]\dfrac{1}{2}D.h \: \rm unit^2[/tex] (if cross section is with respect to diagonal)What is a cross section?When some high dimensional object is sliced by hyperplane, then the area of the intersection of the hyperplane with the object is the cross-section.
For the given case, the right rectangular pyramid sliced will be having a triangle with height same as that of the pyramid but base equal to either length or the width of the base rectangle, or the diagonal.
Thus, if we consider: L = length of base, W = width of base , D = diagonal's length of the base of the rectangular pyramid, with the height h units, then we get the cross section's area as:
[tex]\dfrac{1}{2}L.h \: \rm unit^2[/tex] (if cross section is with respect to length)[tex]\dfrac{1}{2}W.h \: \rm unit^2[/tex] (if cross section is with respect to width)[tex]\dfrac{1}{2}D.h \: \rm unit^2[/tex] (if cross section is with respect to diagonal)Learn more about area of cross-section here:

x + 6y = –6
Answer:
[tex]y=-\frac{x}{6} -1[/tex]
Step-by-step explanation:
Hi there!
We are given the following equation:
x+6y=-6
And we want to convert it into slope-intercept form
Slope-intercept form is known as y=mx+b, where m is the slope and b is the y intercept
The equation is currently in standard form, which is ax+by=c, where a, b, and c are integer coefficients
Notice how in standard form, both the terms that contain x and y are on one side, but in slope-intercept form, y is by itself on one side
So essentially, in order to convert from standard form to slope-intercept form, we need to solve for y
Here is our equation again:
x+6y=-6
Start by subtracting x from both sides
x+6y=-6
-x -x
_______________
6y=-x-6
Now divide both sides by 6
[tex]y=-\frac{x}{6} -\frac{6}{6}[/tex]
We can simplify the fractions to become:
[tex]y=-\frac{x}{6} -1[/tex]
Hope this helps!

12men can clear a field in 5 days.How long would it take 15 men to clear the same field
Answer: 4 days
Step-by-step explanation:
We can divide to find how much of a field each man can clear in one day. Since it takes 12 men 5 days to clear a field, each man can clear 1/60th of a field each day.
If we multiply 15 men by 1/60th of a field per day, we see that the 15 men can clear 1/4th of a field each day, so it would take 4 days for them to clear the entire field.

Which statement correctly describe the data shown in the scatter plot?
The scatter plot shows a negative association.
The point (2, 14) is an outlier.
The scatter plot shows a linear association.
The scatter plot shows no association.
A graph measuring variable y in relation to variable x. Multiple coordinates indicate a pattern of variable y increasing as variable x increases
Answer:
Hello! I wanted to explain the answer which someone might have already answered.. First off, I want to let you know that the Answer is "The scatter plot shows a linear association." But how? Well, linear means: "arranged in or extending along a straight or nearly straight line." Which if you didn't notice.. All the points on the graph, make up a generally straight line.
"No association" means there is no line or association with any of the points. So, you'd pick that if the points were all over the graph in no order, line or combination; which isn't the case.
"Negative association" is when the top of the points come from the left of the graph lowering into the right. While Positive association would be from right to left. So, it couldn't be choice "Negative Association" since it's coming from right to the left of the graph.
"The point (2, 14) is an outlier." If you didn't know, an outlier is one dot out of a whole group. Think of it as if EVERYONE was wearing pink except one; who wore black. It's just the out of placed kind of dot; but it's supposed to be there. When you look at the graph, there is no dot or outlier at point (2,14) so, that's automatically out as well.
Ending with the last choice "The scatter plot shows a linear association." which is not just true but is the only one that'd make since. So, I hope this helped you!
I HOPE THIS HELPS YOU! BE SAFE :)

Sean is filling his truck with gasoline. He knows the total cost, C, will be proportional to the
number of gallons of gasoline, g, that he puts into the gas tank. After putting 8.5 gallons in
.
the tank, the cost is $23.63.
(a) Find the ratio of the cost to the gallons as
(b) What is the real world meaning of your
a unit rate. Show the division as a fraction answer in (a)?
and then state the answer with appropriate
units.
(c) If c is the cost and g is the number of
gallons bought, write a proportion
involving c and g and then solve it for c.
(d) If Sean puts 17 gallons of gasoline into
his truck, what is his cost? Justify.
Part (a)
Divide the total cost over the number of gallons to get the unit cost
(23.63)/(8.5) = 2.78
Answer: 2.78=======================================================
Part (b)
The result of the previous part indicates the gas costs $2.78 per gallon.
=======================================================
Part (c)
c = cost in dollars
g = number of gallons bought
cost/gallons = cost/gallons
c/g = (23.78)/(8.5)
c/g = 2.78
c = 2.78g
This fits with what part (b) mentioned. The 2.78g means "2.78 times g".
Answer: c = 2.78g=======================================================
Part (d)
Plug g = 17 into the equation found in part (c)
c = 2.78g
c = 2.78*17
c = 47.26
