At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
r + f ≥ 16
4r + 2f ≤ 40
A graph shows r on the x-axis, from 0 to 18, and f on the y-axis, from 0 to 20. Two solid lines are shown. The first line has a negative slope and goes through (0, 20) and (10, 0). Everything to the left of the line is shaded. The second line has a negative slope and goes through (0, 16) and (16, 0). Everything above the line is shaded.

The maximum number of ride tickets that she can buy is A. 4.
How to illustrate the information?It should be noted that the system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
r + f ≥ 16
4r + 2f ≤ 40
The two inequalities are first shown on the graph as seen in the attachment. The graph demonstrates where the two in-equations intersect (4,12).
Consequently, we can observe that r has a maximum value of 4. This was illustrated in the graph.

Answer:
a) 50, b) -40, c) 3Step-by-step explanation:
Arithmetic mean is the average of the numbers.
a) (40 + 60)/2 = 100/2 = 50b) (- 60 - 20)/2 = - 80/2 = - 40c) (7/3 + 11/3)/2 = (18/3)/2 = 6/2 = 3Formula we use is,
→ Mean = (x + y)/2
a) 40 and 60 = ?
→ (40 + 60)/2
→ 100/2 = 50
Thus, the mean is 50.
b) -60 and -20 = ?
→ (-60 - 20)/2
→ -80/2 = -40
Thus, the mean is -40.
c) (7/3) and (11/3) = ?
→ ((7/3) + (11/3))/2
→ (18/3)/2
→ 6/2 = 3
Thus, the mean is 3.

money marilyn is going on a class outing to an amusement park. she has $40 to spend. the admission price is $20. she plans to buy a sandwich for $5. a cup of lemonade costs $3.00. write an inequality to show how many cups of lemonade, c, she can buy.
Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) cups of lemonade from the rest of the money.
Here we have,
Total money to spend= $40
Admission price= $20
Sandwich= $5
Add all expenses to find the money spent by Money Marilyn.
Total expense= admission price + sandwich
Total expense = $20 + $5 = $25
Amount left with her= $40-$25 = $15
The number of cups when each cup's cost is $3
Total lemonade(x) = $15/$3 = $5
In an equality,
Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) lemonades from the rest of the money.

assuming that the value of x is 4, and the value of y is 6, what is the value of the following expression? (x - y)**2 > y
The result of the expression "(x - y)**2 > y" is -4>6 and it is false.
Information about the problem:
(x - y)**2 > yx = 4y = 6To solve this problem, we have to substitute the values of (x) and (y) and solve the equation:
(x - y)**2 > y
(4 - 6)**2 > 6
-2 ** 2 > 6
-4 > 6
The expression is false because - 4 is not higher than 6. The correct expression is:

the cost of a can of coca-cola in 1960 was $ 0.10 . the function that models the cost of a coca-cola by year is c ( t )
The cost of the Coca-Cola can will be $1 in the year 2000.
Given that the cost of a can of Coca-Cola can in 1960 = $0.10
The function which models the cost of a Coca-Cola by year 't' is
c(t) = [tex]0.10e^{0.0576t}[/tex].
Here, 't' denotes the number of years since 1960.
c(t) is an exponential function.
We have to find the year in which the cost of a can will be $1.
So substitute c(t) = 1, we get,
1 = [tex]0.10e^{0.0576t}[/tex]
⇒ [tex]10 = e^{0.0576t}[/tex]
We have, [tex]ln(e^x) = x[/tex] .
Taking logarithm on both sides, we get,
log(10) = 0.0576t
⇒ [tex]t=\frac{ln(10)}{0.0576}[/tex] = 39.97 ≈ 40 years .
Thus the cost of a can of Coca-Cola will be $1 in the year, 1960 + 40 = 2000.

At the beginning of the day, the stock market goes down 70 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 3/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
The change for the day is 10 1/4
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 3/4
and also that the days low is 70 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 3/4- 70 1/2= 323/4-141/2= (323-282)/4= 41/4
hence the change for the day is 41/4 =10 1/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 3/4- 70 1/2/70 1/2*100= 41/4/70 1/2 *100
%change= 41/4*2/141*100
