Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought lunch from home. Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.
If each spinner is divided into 15 congruent sectors, how does the spinner representing Mr. Skinner’s class differ from the spinner representing Ms. Cho’s class?
One more sector of the Skinner-class spinner will represent bringing lunch from home.
One fewer sector of the Skinner-class spinner will represent bringing lunch from home.
Two more sectors of the Skinner-class spinner will represent bringing lunch from home.
Two fewer sectors of the Skinner-class spinner will represent bringing lunch from home.

Gina has a $50 gift card to a bagel shop. Each Friday, she purchases breakfast for $6. She created a graph to represent the amount of money on her gift card each week. Does Gina's graph represent the situation? Why or why not?
Math item stem image
CLEAR CHECK
Yes, because she starts with $50 on her gift card.
No, because the amount of money on her gift card should decrease each week.
Yes, because the amount of money that she spends increases each week.
No, because the graph should start at the origin.
Answers
Answer:
No, because the amount of money on her gift card should decrease each week.
Step-by-step explanation:
Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answers
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175

Which phrase best represents the following?
n
_ =7
5
Answers
“ n/5 = 7 ”
Usually whenever you have a letter value in mathematics it’s understood as a(n) UNKNOWN value; people label them as a invisible 1
~ FIRST: you have to MULTIPLY both of your SIDES by 5
1n/5 • 5 = 7 • 5
~ CANCEL out; 1/5 • 5 because that gives you a 1
~KEEP: 7 • 5 because it gives the value of your “n”
New equation: n = 7 • 5
7 • 5 = 35
Answer: n = 35 ☑️
Regular division problem: 35/5 = 7 so this makes it true!
Random fact; math actually repeats a lot.. so it can become easier for you to understand or tackle problems like this on your own!
Good luck on your assignment and enjoy your day!

[tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]
Cross multiply,
4 * 72 = 32 * 10

So, these are not in proportion.
