I really only need confirmation here... I’m stuck on which of the two answers (A or C) it is.

Hector’s service club is raising money by wrapping presents in the mall. The function f(x) = 3x describes the amount of money, in dollars, the club will earn for wrapping x presents. They only have enough wrapping paper to wrap 1000 presents.

Describe the domain of the function.

A. All real numbers such that 1000 ≥ x ≥ 0 (I flipped the problem because I couldn’t find the sign. Really it would be 0 ≥ x ≥ 1000 with the signs facing the other way)

B. All real numbers

C. All whole numbers such that 1000 ≥ x ≥ 0 (I flipped the problem because I couldn’t find the sign. Really it would be 0 ≥ x ≥ 1000 with the signs facing the other way)

D. All whole numbers

A school has 400 students. They all come to school by bus, and each bus carries the same number of students. How many students might there be on each bus?

I put some counters into groups with the same number in each group. I can’t remember what I did, but I do remember that I had 12 counters. What might the groups have been?

Answers

Answer:

23 times 8 then divide the answer by two

(i looked it up and the answers are the same.)

Question 1 A. Do 23 times 2 times 2. This will give you the same answer as if you were to use 4.

Question 1 B. Use 10 times 2 plus the number in the ones place, then multiply  them together.

Question 2. There would be an average of 40 student per bus, therefore, there will be 10 buses, and 40 students in each bus.

Question 3. You could put 12 counters in: 6 groups of 2, 2 groups of 6, 4 groups of 3, or 3 groups of 4. (I think there's more but that's all I can think of. Hope you got the memo)

Answers

Answer:

The answer is 8 bags of popcorn and then $52.5

Step-by-step explanation:

The answer will be 8 bags of popcorn and the total for the right side would be $52.50.

In order to do this, you need to find the unit rate. In order to find the unit rate, divide 11.25 and 3. The answer should be 3.75. Using this number, divide 30 by 3.75 to get 8. 8 will be the number of popcorn bags sold. Then all you have to do is multiple 14 by 3.75 to get $52.50.

Hope this helps!

Answer: 22/12 = 11/6

Step-by-step explanation:

Again Lol ima copy and paste my same answer.

Hey there!

Let's write this as a ratio/proportion.

The sum of this basic ratio is 4.25.

To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.

34/4.25=8

Now, we multiply our two ingredients by eight.

2.75(8)=22

1.5(8)=12

Note that these two add up to make 34 tablespoons.

Therefore, we have...

22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.

I hope this helps! Have a great day! :)
