Answer:
80 tickets
Step-by-step explanation:
Given the profit, y, modeled by the equation, y = x^2 – 40x – 3,200, where x is the number of tickets sold, we are to find the total number of tickets, x, that need to be sold for the drama club to break even. To do that we will simply substitute y = 0 into the given the equation and calculate the value of x;
y = x^2 – 40x – 3,200,
0 = x^2 – 40x – 3,200,
x^2 – 40x – 3,200 = 0
x^2 – 80x + 40x – 3,200 = 0
x(x-80)+40(x-80) = 0
(x+40)(x-80) = 0
x = -40 and x = 80
x cannot be negative
Hence the total number of tickets, x, that need to be sold for the drama club to break even is 80 tickets

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.
Acellus help slope intercept
Greetings.
The answer is y = 2x + 7.
Explanation:
If you are an expert in graph then you are able to find the slope without calculating. (Rise over Run by looking at the graph.)
We can also find the slope by calculating m-value.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] ---> Rise Over Run
But how are we gonna calculate if we don't have any two given ordered pairs?
The answer is, we can just pick two ordered pairs that are part of the graph, or rather say that the graph passes through.
The graph passes through (-3,1) and (-2,3).
Then we can calculate the slope by using rise/run.
[tex]m=\frac{3-1}{-2-(-3)}\\m=\frac{2}{-2+3}\\m=\frac{2}{1}\\m=2[/tex]
Thus, the slope is m = 2.
However, we are not done yet. We just only found out the slope. We need to find the y-intercept too.
From Linear Function - [tex]y=mx+b[/tex]
Where m = slope and b = y-intercept.
Since b = y-intercept, we don't need to calculate/substitute x = 0. We simply find which number the graph has y-intercept at.
Which is (0,7), the y-intercept.
Then we substitute b = 7 as y-intercept.
Thus the answer is [tex]y=2x+7[/tex]

Answer:
A. 2.10b + 12.99 = 21.39; 4 bottles
Step-by-step explanation:
The b represents bottles of water, at the end of the equation. If each bottle is $2.10, and there were 4 bottles brought, $2.10 * 4 = $8.40, and $8.40 + $12.99 is $21.39.

Johnny filled a 5 gallon bucket with water. How many quarts of water does Johnny have?
Answer:
20 quarts
Step-by-step explanation:
Five gallons is equal to 20 quarts.
I hope it helps.
Answer:
20 quarts
Step-by-step explanation:
in 1 gallon there is 4 quarts so if theres 5 gallons there would be 4 quarts for each, so multiply 5 by 4, becuase you need 4 quarts in every gallon, the product (answer to a multiplication problem) to that is 20. :)

Solve for 10+5X<=20 please help me
Answer:
The answer is x=2. I hope that this helps.
Step-by-step explanation:
Answer:
If you're solving for x it should be x <= 2
Step-by-step explanation:
10 + 5x <= 20 -- isolate variable (subtract 10 from both sides)
-10 -10
5x <= 10 -- single out the x (divide both sides by 5)
/5 /5
x <= 2
Hope this helps :)

Answer:
[tex]F' = (-3,-3)[/tex]
[tex]G' = (-3,3)[/tex]
[tex]H' = (6,-3)[/tex]
Step-by-step explanation:
Given
The attached graph
[tex]Scale\ Factor = 1\frac{1}{2}[/tex]
Required
Determine the coordinates of F'G'H'
First, we need to get the coordinate of F, G and H from the graph
[tex]F = (-2,-2)[/tex]
[tex]G = (-2,2)[/tex]
[tex]H = (4,-2)[/tex]
The dilated coordinate is then calculated as:
[tex](FGH)' = (FGH) * Scale\ Factor[/tex]
This gives:
[tex]F' = (-2,-2) * 1\frac{1}{2}[/tex]
[tex]F' = (-2* 1\frac{1}{2},-2* 1\frac{1}{2})[/tex]
[tex]F' = (-3,-3)[/tex]
[tex]G' = (-2,2) * 1\frac{1}{2}[/tex]
[tex]G' = (-2 * 1\frac{1}{2},2 * 1\frac{1}{2})[/tex]
[tex]G' = (-3,3)[/tex]
[tex]H' = (4,-2) * 1\frac{1}{2}[/tex]
[tex]H' = (4 * 1\frac{1}{2},-2 * 1\frac{1}{2})[/tex]
[tex]H' = (6,-3)[/tex]

11. A tank is being filled up with water. At t=0, we know that the tank holds 150 gallons of
water, and after one hour ( t=1) , it holds 180 gallons of water.
a) Assuming that the volume of water in the tank, V, is a linear function of time, t, in hours,
find a formula for V ( linear function)
b) BY what percent did the volume of water increase from t=0 to t= 1?
Answer:
V = 30t + 15020%Step-by-step explanation:
Given
Initial volume = 150 galVolume after 1 hour = 180 gala) The volume formula will be:
V = 30t + 150As 150 is y-intersect (volume at zero time) and the rate of change (the slope) is 30 gal per hour
b) Increase of volume by percent:
30 gal increase on top of 150 gal
30/150*100% = 20%Answer:
20%
Step-by-step explanation:
The volume formula is V = 30t + 150 → where 150 is y-intersect and the slope is 30 gals per hour
So you can do:
30 gals of increase on top of the 150 gals to get:
30/150×100% which equals 20%

please answer fast :(((
Answer:
KP = 6
Step-by-step explanation:
From the information given, K is the centroid.
Therefore, based in the centroid theorem:
KP = ⅓(AP)
AP = 18
Plug in the value of AP into the equation
KP = ⅓(18)
KP = 6
