At the first pep rally of the season, the football team and the volleyball team were presented to the student body. During the pep rally, up to 11 players talked to the crowd. Football players talked about 17 seconds each and volleyball players talked about 28 seconds each.
If the players only had a total of 242 seconds (4.03 minutes), which system of inequalities could be used to determine the number of football players (f) and volleyball player! (v) that could talk to the student body?
A. f+ y< 11 17f+ 287< 242
B. ftv< 11 17y + 28% < 242
C. f+ v< 11 176+ 28v< 242
D. ftv< 11 17v+28f< 242
Answer:
A. f + y ≤ 11
17f + 287 ≤ 242
Step-by-step explanation:
[] Let f be football players and v be volleyball players.
-> The total time must be less than or equal to 242 seconds.
-> If football players talked for 17 seconds, we can write it as 17f.
-> If volleyball players talked for 28 seconds, we can write it as 28v.
[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.
-> 17f + 28v ≤ 242
[] This is going to be a part of our system of inequalities
-> Because of this, we rule out the following options.
B & D - the football players talk for 17 seconds, not the volleyball players
C - not less than or equal too, only less than
[] This leaves us with the option of A.
-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

1. Chef Alfredo has noticed some changes in his business. He usually sells 45 pizzas on Sunday afternoons. During
football season, he has big television screens televising NFL games and he sells 72 pizzas.
a. What is the percent change?
b. did it increase or decrease?
c. answer in a complete question
(PLEASE SHOW WORK)
Answer:
a. 60%
b. increase
Step-by-step explanation:
To find the percentage, you can divide 72 by 45 to get the decimal increase, or 1.6. Percentage rates are decimals, and you can think about this like coloring 60 circles out of 100, representing 60% of 100. Since 72 is higher than 45, this was a percentage increase.

Chef Alfredo invested $4800 at a simple interest rate of 5% and can now afford a $6,000 state-of-the-art pizza
oven. How many years ago did he make this investment? Show all your work and answer in a complete sentence.
Chef Alfredo made the investment 4 years ago.
To solve this problem, we have to use the formula of simple interest.
Data;
rate = 5%principal = 4800Simple Interest + principal = $6000T = time ?Simple InterestThe formula of simple interest is given as
[tex]S.I = \frac{PRT}{100}[/tex]
Let's subtract the principal from the final amount to know the simple interest
[tex]6000-4800=1200[/tex]
Substitute the values into the formula

Becky tells her friend about the Rule of 72 and her friend immediately
tries it out with her own example. Becky doesn't see all of her friend's
math but does see f(4) = 18 written on her friend's paper.
a. What do you know about the friend's investment based on this?
b. Is the friend's math correct based on the rule of 72?
Answer:
a. the investment earns 4%
b. yes
Step-by-step explanation:
The "rule of 72" says that an investment earning compound interest at x% will double in value after 72/x years. That is, ...
f(x) = 72/x
__
a.We interpret f(4) to mean Becky's friend is interested in the doubling time for an investment that earns 4% interest.
__
b.Using the above formula, ...
f(4) = 72/4 = 18
The friend's math is correct.

please no link this is meant for my son
Answer:
4/15
Step-by-step explanation:
They have baked 1/3 + 2/5. To add you need common denominators.
1/3 = 5/15, 2/5 = 6/15
5/15 + 6/15 = 11/15. This is what they baked.
To find what is left, we need to subtract from 1. 1 = 15/15
15/15 - 11/15 = 4/15
Which of the following sets are continuous? Check all that apply.
A. {2, 4, 6, 8, ...)
B. (-0, +00)
C. (30, 45]
D. [60, 100)
E. {3,7)
Answer: The correct answer option is B.
Step-by-step explanation:
We are to determine whether which of the given data sets in the answer options are continuous.
For this, we need to know what a continuous data set is.
A data set that has no definite end to its value but keeps on continuing.
Here, the data sets are given in A, C, D, and E have definite starting and ending points.
While B is a continuous set as its values are continuing to infinity.
What is the equation of the line that goes through the points (1,1) and 3,-3)
Answer:
y = -2x + 3
Step-by-step explanation:
[]Let us write an equation in slope-intercept form.
-> See attached
-> Our equation will start out as y = x
[] The slope can be found by taking the change in y divided by the change in x
-> [tex]\frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2[/tex]
-> Now our equation is y = -2x
[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.
-> y = -2x + b
(1) = -2(1) + b
1 = -2 + b
3 = b
-> Now our equation is y = -2x + 3, which is our final answer.

Answer:
y = -2x +3
Step-by-step explanation:
coordinates given (1,1) and (3,-3)
How to find equation? first find slope.
slope formula:
(y2-y1)/(x2-x1)
using this formula:
(-3-1)/(3-1)
-4/2
-2 ........this is slope also refereed as (m) in short form.
Use the formula:
y - y1 = m( x - x1)
using the formula:
y - 1 = -2( x - 1)
y -1 = -2x + 2

The diagram shows three straight lines work out the size of angles a, b and c.
Answer:
a = 21°
b = 70°
c = 89°
Step-by-step explanation:
a = 21° as vertically opposite angles are equal
to work out b:
angles on a straight line add up to 180
b + 110 = 180
b = 180 - 110
b = 70°
to work out c:
the sum of angles in a triangle add up to 180
we have a and b
21 + 70 + c = 180
91 + c = 180
c = 180 - 91
c = 89°

Given: f(x) = 5x* - 3x² + 6x + 2. Find f(-2).
Answer:
f(-2) =-32
Step-by-step explanation:
f(x) = 5x* - 3x² + 6x + 2. f(-2)
f(-2) = 5(-2) - 3([tex]-2^{2}[/tex]) + 6(-2) + 2
f(-2) = -10 - 3(4) -12 + 2
f(-2) = -10 - 12 -12 + 2
f(-2) = (-10 - 12 -12) + 2
f(-2) = (-10 -24) + 2
f(-2) = (-34) + 2
f(-2) =-32

f(-2) ?
substitute -2 as x into the equation of the function
f(-2) = 5(-2) - 3(-2)² + 6(-2) + 2
Note :positive × negative = negative(-x)² = -x × (-x)negative × negative = positive[tex]f( - 2) = - 10 - 3.4 + ( - 12) + 2[/tex]
