1. Allison’s middle school team has designed t-shirts containing their team name and color. Allison and her friend Nicole have volunteered to call local stores to get an estimate on the total cost of purchasing t-shirts. Print-o-Rama charges a set-up fee, as well as a fixed amount for each shirt ordered. The total cost is shown below for the given number of shirts. Value T’s and More charges $8 per shirt. Which company should they use?
a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.
b. What is the constant of proportionality of Value T’s and More? What does it represent?
c. How much is Print-o-Rama’s set-up fee?
d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.
Answer:
the numbers are missing here, so I looked for a similar question:
Print-O-Rama
# shirts total cost
10 $95
50 $375
a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.
Value T’s and More offers a proportional relationship since each t-shirt costs $8 regardless of the number of t-shirts
b. What is the constant of proportionality of Value T’s and More? What does it represent?
$8 per t-shirt
f(c) = $8t
the function of total cost = $8 times the number of t-shirts ordered
c. How much is Print-o-Rama’s set-up fee?
using the high-low method
variable cost = ($375 - $95) / /50 - 10) = $7 per t-shirt
fixed cost (set-up fee) = $375 - (50 x $7) = $25
d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.
purchasing 90 t-shirts at Print-o-Rama costs = $25 + (90 x $7) = $655
purchasing 90 t-shirts at Value T’s and More costs = 90 x $8 = $720
you should purchase the t-shirts at Print-o-Rama since the cost is lower.

Suppose Ms. Kraus is 1.75 m tall. When her shadow is is 1 m, how long would the shadow be of a 265 m tall building? (Make a sketch to help solve the problem) a. 175 m c. 265 m b. 151 m d. 100 m
Answer:
b. 151m
Step-by-step explanation:
Step-by-step explanation:
That's the right answer on edge
The shadow of a 265m long building would be b. 151 m
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Ms. Kraus is 1.75 m tall. When her shadow is 1 m.
Let the shadow of a 265 m tall building be 'x' m.
Therefore by the ratio proportion method.
1.75 : 1 : : 265 : x.
1.75/1 = 265/x.
1.75x = 265.
x = 265/1.75.
x = 151.42 Or 151 m.

Functions f, g, and h are defined as follows: f(x) = x +1, g(x) = x^2 +1, and h(x) = x^3 +1.
(a) Find the inverse of function g(x).
(b) Find f(h(-2))
(c) Find g(f(3)
Answer:
a. let the gx be x
g(x) = x^2+1
or, x^2+1=y
or, x^2= y-1
:. x=2 root y-1
inter changing the relation of xand y
:. x=2 root y-1
:. g-1(x)= 2root x-1

O (-4,2),
O (-4,2), -3
0 (0,1),
The line is passing through (2, 0) and (0, 0.8) and the slope is 0.4. Then the correct option is A.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
From the line, we can observe that the line is passing through (2, 0) and (0, 0.8).
Then the slope of the line will be
Slope = (0.8 – 0) / (0 – 2)
Slope = 0.4
Then the correct option is A.

The probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The amount on the receipt = {8, 10, 10, 15, 25, 32}
Total outcome = 6
The amounts are grouped as more than $20 and less than $20.
The event is the amount on receipt more than $20 = {25, 32}
Total favourable outcome = 2
Probability = 2/6 = 1/3 or
= 0.33
Thus, the probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.

Answer:
g(x) = 1/4 f(x)
Step-by-step explanation:
f passes through the origin and has a slope of 1.
f(x) = x
g passes through the origin and has a slope of 1/4.
g(x) = 1/4 x
Substituting:
g(x) = 1/4 f(x)
Find the series in A.P whose sum to n terms is n*(n+2)
Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
[tex]S_{n}[/tex] = n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11

You would have to look up how to do the hadn written way of figuring out this but I just used my calculator. To do this with your TI-84 or newer calculator, press "stat" and go into "edit". You will see some columns with the names "L1, L2, L3, etc." which stand for lists. put your x values in "L1" and their corresponding y values next to them in "L2". When you're done press stat again and move right to the heading "Calc". Go down to number 4 which should say "LinReg(ax+b)" next to it and press enter. now you should see "Xlist" and "Ylist" with "L1" and "L2" beside them respectively. Once that is set, go down to "Calculate" and press enter and it should give you slope intercpet form and what "a" and "b" are. You're welcome.~ ;P
Chocolate chip and peanut butter cookies are randomly chosen from a cookie jar and placed onto a plate. The first plate had four chocolate chip cookies and one peanut butter cookie. A second plate was prepared with 2 chocolate chip cookies and P peanut butter cookies. If the total probability of drawing a chocolate chip cookie from the first plate and then the second plate is 8/25, how many peanut butter cookies, P, are on the second plate? PLEASE HELP THIS IS A FORMATIVE I HAVE TO FINISH THIS TEST AT 12:55, AND IT IS 12:29 RIGHT NOW PLEASE HELP <:(
Answer:
3 peanut cookies
Step-by-step explanation:
Given that :
Plate 1:
Number of chocolate chip = 4
Number of peanut butter cookies = 1
Probability of drawing chocolate chip cookies from plate 1 :
Probability =( number of required outcome / Total possible outcomes)
P(chocolate chip) = 4 / 5
Plate 2:
Number of chocolate chip = 2
Number of peanut butter cookies = p
P(chocolate chip) = 2 / (2 + p)
Probability of drawing chocolate chip from plate 1 and then plate 2 = 8/ 25
(4/5) * 2/(2+p) = 8/ 25
8 / (10 + 5p) = 8/ 25
8(10 + 5p) = 8 * 25
80 + 40p = 200
40p = 200 - 80
40p = 120
p = 3
