I am selling raffle tickets. It cost $155 to print the tickets and I want to make at least a $2,500 profit how much money do I need to raise to cover the cost of the printing and meet my goal
Answer:
Step-by-step explanation:
You need $2500 plus the amount to print the tickets. So 2500+155= $2655.
$155 will break even and then the $2500 will be the profit.
Side Panel Expand side panel 7.01 Discussion: Sequences and Modeling with Functions Think about Pascal's triangle. Many numerical sequences exist in this triangle. Research/explore the triangle. Give an explicit or recursive rule or explanation for the sequence you found. For example, the sum of the diagonals gives the Fibonacci sequence. Give an example of where in the triangle your sequence is located.
Answer:
The sum of the triangle gives us the Fibonacci sequence. The sequence starts with 0 and 1, then adds along the road, such as 3+5=8, and 5+8=13.
It's a pattern going along while adding sequences together.

What does a function and a non-function mean?
Answer:
A function is a relation between domain and range such that each value in the domain corresponds to only one value in the range. Relations that are not functions violate this definition. They feature at least one value in the domain that corresponds to two or more values in the range.

What is the exact solution to the system of equations shown on the graph?
OA (-1.4)
oc (-1,63)
OD. (-1,43)
Answer:
[tex] (-1\frac{1}{3}, 4\frac{3}{5}) [/tex]
Step-by-step explanation:
To find the exact solution, find the equation for each line. And solve for x and y.
To do this, represent each equation in the slope-intercept form, y = mx + b. Where m is the slope, and b is the y-intercept.
✍️Equation 1 for the line that slopes upwards from left to your right:
Slope = [tex] m = \frac{rise}{run} = \frac{2}{1} = 2 [/tex]
b = the point at which the y-axis is intercepted by the line = 7
Substitute m = 2 and b = 7 in y = mx + b
Equation 1 would be:
✔️y = 2x + 7
✍️Equation 2 for the line that slopes downwards from left to your right:
Slope = [tex] m = \frac{rise}{run} = -\frac{3}{1} = -3 [/tex]
b = the point at which the y-axis is intercepted by the line = 1
Substitute m = -3 and b = 1 in y = mx + b
✔️Equation 2 would be:
y = -3x + 1
✍️Solve for x and y:
✔️To solve for x, substitute y = -3x + 1 in equation 1.
y = 2x + 7
-3x + 1 = 2x + 7
Collect like terms
-3x - 2x = 7 - 1
-5x = 6
Divide both sides by -5
[tex] x = \frac{6}{-5} = -1\frac{1}{5} [/tex]
✔️To solve for y, substitute x = -1⅕ in equation 2.
y = -3x + 1
[tex] y = -3\frac{-6}{5} + 1 [/tex]
[tex] y = \frac{18}{5} + 1 [/tex]
[tex] y = \frac{18 + 5}{5} [/tex]
[tex] y = \frac{23}{5} [/tex]
[tex] y = 4\frac{3}{5} [/tex]
✅The exact solution would be: [tex] (-1\frac{1}{3}, 4\frac{3}{5}) [/tex]

A pet store has 115 fish that need to be placed into fish tanks. Each tank hold 6 fish. How many tanks does the store for the fish
Answer:
19.1, rounded= 19
Step-by-step explanation:
115 divided by 6 = 19.1
Answer:
20 tanks
Step-by-step explanation:
Number of tanks = Total fish ÷ Number of fish that a tank can hold
= 115 ÷ 6
= 19 [tex]\frac{1}{6}[/tex]
= 20 tanks

Approximately 6.5x10^7 people fly commercially in the United States each month. Approximately how many fly commercially each year?
The number of people that travel commercially each year is 7.8 x 10^8.
How many fly commercially each year?The number of people that travel commercially each year is represented in scientific notation. Scientific notation is used to compress larger numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
In order to determine the number of people who flew commercially each year, multiply the number of people who flew each month by 12.
Number of people who fly commercially each year = 6.5x10^7 x 12
= 78 x 10^7
= 7.8 x 10^8

You work in a hospital, and instructions for an instrument state that it should be cleaned in the sterilizer for two hours. The sterilizer requires cleaning time be entered in minutes. How many minutes do you set for the sterilizer?
Answer:
120 mins
Step-by-step explanation:
number of minutes in an hour = 60
number of hours = 2
total number of minutes = 60 x 2 = 120
Answer:
120 minutes
Step-by-step explanation:
an hour is 60 minutes and if you put them in for 2 hours you multiply 2×60 and your answer is 120
The ratio of the measures of the sides of a triangle is
1:15:3. If the perimeter of the triangle is 152 yards,
find the length of the longest side.
Answer:
The length is 120 yards
Step-by-step explanation:
Here, we want to find the length of the longest side
The longest side ratio is 15
Add up all the ratio,
We have 1 + 15 + 3 = 19
So the length will be;
15/19 * 152
= 120 yards
PLEASE HELP! Whoever answers correctly will get brainliest
Answer:
The statement at the top says that the triangles are 'similar'. That means that the corresponding angles are equal, and each pair of corresponding sides have the same ratio. From the 4 and the 8, you can see that each side in the small one is 1/2 the length of the corresponding side in the big one. So the missing sides are 1/2 the length of the 7 and the 12.

What is an equation of the line that passes through the point (1,-3) and is perpendicular to the line x+3y=21?
Answer:
x + 3y =21 equation 1
let the equation perpendicular to X + 3y = 21 be
3x - y + k = 0 equation 2
since the point ( 1 , -3 ) passes through equation 3x - y +k =0
3× 1 - (-3) + k = 0
or, 3 + 3 + k = 0
or, 6 + k =0
or, k = -6
now,
putting the value of k in equation 2
3x - y + k = 0
or, 3x -y -6=0
Sequences and series
===========================================================
Explanation:
The sequence is not arithmetic because the distance between adjacent terms keeps increasing. For instance, the gap from 0.4 to 1.6 is 1.6-0.4 = 1.2, while the gap from 1.6 to 6.4 is 6.4-1.6 = 4.8. There is no common difference, so we can rule out choices A and B.
To check if we have a geometric sequence, divide each term by its previous term
(term2)/(term1) = (1.6)/(0.4) = 4
(term3)/(term2) = (6.4)/(1.6) = 4
(term4)/(term3) = (25.6)/(6.4) = 4
Each time we get 4 as a result, so this sequence is geometric and the common ratio is r = 4.
Put another way: each new term is found by multiplying the previous term by 4.
0.4*4 = 1.6
1.6*4 = 6.4
6.4*4 = 25.6
This all leads to D being the answer.
Side note: the nth term of this geometric sequence is [tex]a_n = 0.4*(4)^{n-1}[/tex] where n is a positive integer and starts at n = 1.

carrie and joel plan to sell apple pies at the county fair for $6 each. the ingredients they used cost $3.75 per pie. they rent an oven for $54 to keep the pies hot throughout the day. how many pies must carrie and joel sell in order to break even?
Answer:
24 pies
Step-by-step explanation:
Let x represent the number of pies and set up an equation:
6x = 3.75x + 54
Solve for x:
6x = 3.75x + 54
2.25x = 54
x = 24
So, Carrie and Joel have to sell 24 pies to break even
