Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes. If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.

A. Yes; Machine A and Machine B make 77.5 ounces in 10 minutes. 77.5 > 72, so there will be enough popcorn.

B. Yes; Machine A and Machine B make 87.5 ounces in 10 minutes. 87.5 > 72, so there will be enough popcorn.

C. No; Machine A and Machine B make 67.5 ounces in 10 minutes. 67.5 < 72, so there will not be enough popcorn.

D. No; Machine A and Machine B make 30.75 ounces in 10 minutes. 30.75 < 72, so there will not be enough popcorn.

Answers

Answer: Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).

Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).

Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes

Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes

After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.

So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.

If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.

Step-by-step explanation:

Answer:

A/B

Step-by-step explanation:

They will have enough popcorn

Either way there will be enough popcorn to make eight 9-ounce bags.

Explain why we need to have a common denominator in order to add or subtract fractions.

Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.

Answers

Answer: The denominator of a fraction tells you the relative size of the pieces. Therefore, the reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size.

Answer:

We need to have a common denominator in order to subtract different fractions because if we have an example like.

5/2 - 6/8 we cannot do that because the denominator is not alike.

We have to use multiplication to help us here.

2 x 8 = 16 !

So. no we have 5/16

so now we do 5 x 8 = 40

So now my new fraction is - 40/16 BUTTTT 40/16 is an improper fraction. so 40/16 = 5/2

Now we are back at the square 1 so now we have to fix 6/8.

8 x 6 = 48

6 x 6 = 36.

2 x 24 = 48.

5 x 24 = 120 or 12

now we have 12/48 and 36/48.

We can subtract now!

Hope this helped for problems like this.

The table shows a proportional relationship between x and y. What is the unit rate of y per x?
A) 1 B) 3 C) 6 D) 9

Answers

Answer:

The unit rate of y per x is 9

Step-by-step explanation:

In this question, we are asked to give the unit rate of x.

To do this, we will critically look to establish the relationship between both set of values.

Looking at the values critically, we can see that the values in the first brackets, when multiplied by 4 will give the values in the second bracket. Hence we can say that the values in the second bracket are multiples of the first by 9.

Answers

Answer: 5x + 16

Step-by-step explanation: distribute, add the numbers, and combine like terms.

Answer:

x = -3.2

Step-by-step explanation:

First, solve parenthesis:

2(x+6)+3x+4= 0 (Given)

2x + 12 + 3x + 4 = 0 (distributive property of equality)

Then, you comibine like terms:

2x + 12 + 3x + 4 = 0

5x + 16 = 0 (Combining like terms)

And then, move the variables to the left and constants to the right:

5x + 16 = 0

5x = -16 (Subtraction property of equality) You subtract 16 from both side, since the variable is on the right already you leave it that way.

Finally, you divide both sides to get the answer ( solve for X):

5x = -16

x = -3.2 (division property of equality)

There is your answer!

Hope this helps!
