Answers

9 = 4 + x - 4x minus 4
5 = x - 4x
5 = -3x divide by -3
-3/5 = x
To solve this we know that 2+7=9 so for 4+1(x)-x4 to equal 9 you would first multiply x and 4 to get 4x. Next you would subtract 1x-4x which equals -3x+4 . What you do to the right you do to the left so 9-4=5. Which you the have 5=(-3x) so you then divide the 3x by 3 which leaves you with x. So x = -5/3 .

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.

Which set of ordered pairs represents a function? (1 point)

Answers

Answer:

The very last set

{(0, 2), (1, 4), (2, 6), (3, 6)}.

The reason why is because of the vertical line test. If there are two y-coordinates on a x-coordinate then it is not a function. A function is that each x-coordinate has a y-coordinate with the x-coordinates being different.

Its A because the ratio from females to males ls 5:3

Answer:

B. He should focus on females because the ratio of females to males is 5:2.

Step-by-step explanation:

By looking at the graph, you can see that there are 25 females and 10 males. The ratio for this is 25:10, but we can simplify by dividing both sides by 5! 25/5=5, and 10/5=2, so the simplified ratio of 25:10 is 5:2. If you look at all of the answer choices, you really don't have to look at the words a lot; there's only one choice that includes the ratio 5:2. That choice is B, so B is the answer!
