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.

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.

show your work pls and this is my 3rd time asking LOL

Answers

It takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back

How to determine how long will it take a bat's cry to reach its prey and echo back?

The given parameters are

Speed = 330 meters per second

Distance = 1 meters

The time taken to get to the prey is calculated as

Speed =Distance/Time

Substitute the known values in the above equation

So, we have

330 = 1/Time

Cross multiply the factors of the equation

So, we have

Time * 330 = 1

Divide both sides of the equation by 330

So, we have

Time 1 = 1/330

Similarly, the time taken to get from the prey is calculated as

Speed =Distance/Time

Substitute the known values in the above equation

So, we have

330 = 1/Time

Cross multiply the factors of the equation

So, we have

Time * 330 = 1

Divide both sides of the equation by 330

So, we have

Time 2 = 1/330

The time it takes a bat's cry to reach its prey and echo back is

Time = Time 1 + Time 2

So, we have

Time = 1/330 + 1/330

Evaluate the sum

So, we have

Time = 2/330

Simplify the quotient

So, we have

Time = 1/165

Hence, it takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back

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

5

Answers

Hey there!

“ 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!
