Answer: 0.43h + 0.65p + 1.31d
Step-by-step explanation:
Profit made from each hotdog sold = $0.43
Profit made from each pretzel sold = $0.65
Profit made from each drink sold = $1.31
Number of hotdogs sold = h
Number of pretzels sold = p
Number of drinks sold = d
Total profit made will then be the profit for each multiplied by the number of things sold. This will be:
= ($0.43 × h)+($0.65 × p)+($1.31 × d)
= 0.43h + 0.65p + 1.31d

What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.?
Use 3.14 to approximate pi, and express your final answer to the nearest hundredth.
Answer:
1017.88
Step-by-step explanation:
The volume of a cone is V=1/3hπr²
First, we are going to do exponents: what is 9*9? 81. So now our equation is V= 1/3h * 3.14 * 81 (Pi is 3.14, so we filled that in too.)
Now we need to find 1/3 of our height, or 1/3 * 12, which is 4. Our equation is now V= 4 * 3.14 * 81
Solve and you get 1017.88

What is the equation of the line that is parallel to y=2x+2 but passes through the point (1,6)
Answer:
y=2x+4
Step-by-step explanation:
y=2x+2
Gradient = 2
Gradient of the line passing through point (1,6)
= 2
i.e it is parallel to line y=2x+2.
Equation of the line is given as:
y - 6 = 2(x - 1)
y - 6 = 2x -2

Daily go from home to school driving my car the school is 15 miles (d) from my house. The speed limit is 30 miles per hour. I have to be at school not after 08:00 am (t1). Repersents the time leave home, where the limit is defined by d=s(t1-t0 What time should I leave home?
Answer:
7:30 a.m
Step-by-step explanation:
Number of miles from house to school(d) = 15 miles
Speed limit (s) = 30 mph
t1 = time to be in school is at most 8:00a.m
t0 = time to leave house
Given the model. :
15 = 30(8 - t2)
15 = 240 - 30t2
30t2 = 240 - 15
30t2 = 225
Divide through by 30
30t2 / 30 = 225/30
t2 = 7.5
Hence, I need to leave home by 7.5 (.5 in minutes = 0. 5*60 = 30 minutes)
Hence, t0 = 7:30,; I need to leave home by 7:30 a.m

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
2. Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4. Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.
Answer:
(THE SPACES ARE THE FRACTIONS)
Step-by-step explanation:
Hence it is a simply rearrangement of the equation to start with, in order to make

This is the graph in ’slope-intercept’ form. From here it is easy to see that gradient =
−
2
3
and that y-intercept = 490.
The easiest way to draw a straight-line graph, such as this one, is to plot the y-intercept, in this case (0, 490), then plot another point either side of it at a fair distance (for example substitute
x
= -5 and
x
= 5 to procure two more sets of co-ordinates). These can be joined up with a straight line to form a section of the graph, which would otherwise extend infinitely either side - use the specified range in the question for x-values, and do not exceed it (clearly here the limit of
x
-values is 0 ≤ x ≤ 735, since neither x nor y can be negative within the context of the question - the upper limit was found by substituting
y
= 0).
In function notation, the graph is:
f
(
x
)
=
490
−
2
3
x
The graph of this function represents how the value of the function varies as the value of x varies. Looking back at the question context, this graph specifically represents how many wraps could have been sold at each number of sandwich sales, in order to maintain the same profit of $1470.
When the profit is higher, the gradient is not changed (this is defined by the relationship between the $2 and $3 prices, not the overall profit) - instead the
y
-intercept is higher:
2
x

y

Therefore we have gleaned that the new y-intercept is 531.
Clearly I cannot see the third straight line. However the method for finding the equation of a straight line graph is fairly simple:
1. Select two points on the line and write down their coordinates
2. The gradient of the line =
c

−

4. Find the change in
x
(Δ
x
=
x
2
−
x
1
5. Divide the result of stage 3 by the result of stage 4
6. This is your gradient
7. Take one of your sets of coordinates, and arrange them in the form
y
=
m
x
+
c
, where your
m
is the gradient you just calculated
8. There is only one variable left, which is
c
(the y-intercept). Simply solve for this
9. Now generalise the equation, in the form
y
=
m
x
+
c
, by inputting your gradient and y-intercept whilst leaving the coordinates as
y
and
x
For example if the two points were (1, 9) and (4, 6):
Δ
y
= 6 - 9 = -3
Δ
x
= 4 - 1 = 3
m
=
−
3
3
= -1
I choose the point (4, 6)
6 = (-1 * 4) + c
6 = c - 4
c = 10
Therefore, generally,
y
=
10
−
x
Within the context of the question, I imagine the prices of the two lunch specials will be the same in the third month and hence the gradient will still be
−
2
3
- this means steps 1-6 can be omitted. Furthermore if the axes are clearly labelled, you may even be able to just read off the y-intercept and hence dispose with steps 1-8!

R = x squared divided by y. x = 4.8 x 10 to the power of 5. y = 2.8 x 10 to the power of 4. Work out the value of R. Give your answer in standard form to an appropriate degree of accuracy.
Answer:
[tex]R = 1.714\times 10^{6}\\[/tex]
Step-by-step explanation:
Give the expression [tex]R = \frac{x^2}{y}[/tex]
Given
[tex]x = 4.8 \times 10^5\\y = 2.8 \times 10^4[/tex]
[tex]R = \frac{(4.8\times 10^5)^2}{2.8\times10^4}\\R = \frac{4.8\times 10^{10}}{2.8\times10^4}\\R = \frac{4.8}{2.8} \times 10^{10-4}\\ R = \frac{4.8}{2.8} \times 10^{6}\\R = 1.714\times 10^{6}\\[/tex]
Hence the value of R is [tex]R = 1.714\times 10^{6}\\[/tex]

What Is The Slope Of The Line Passing Through (-3, 5) and (5, -3)?
A. Slope = -1
B. Slope = 0
C. Slope = 1
D. No Slope
Answer:
Answer choice A. Slope -1
Step-by-step explanation:
If we plot the two points on a graph we can see that the points go from left to right, starting from a higher point to a lower point. This means the slope is negative. B and D are the same choice, but just in different words, and 0 cannot be positive or negative. and C is positive, not negative. So it is A. I hope this helps, and I hope it's not wrong, but I don't think it is.

Shirts are on sale for 20%.You buy 2 of them. As you pay, the cashier says, “20% off of each shirt means 40%off the total price.” Do you agree or disagree? Please explain thoroughly.
Step-by-step explanation:
Disagree.
If each shirt is originally x dollars, then the new price is 0.8x. So the total cost is 1.6x, down from the original 2x.
So the discount is (2x − 1.6x) / 2x × 100% = 20%.
