Nestor will rotate triangle ABC 180° about one of the labeled points. Nestor says, “The image and pre-image will touch the pre-image at more than one point.”

Which points could be his center of rotation?

Select each correct answer.

point A

point B

point C

point D

point E

point F

The question is asking to choose among the following choices that states the point that could be the center of the rotation, and base on the choices, I would say that the answer would be point D, E, and F, that could be the rotation, I hope you are satisfied with my answer and feel free to ask for more

Answer:

The Correct Answer is Points: D & E

Let y represent the total cost of publishing a book (in dollars). Let x represent the number of copies of the book printed. Suppose that x and x are related by the equation. What is the change in the total cost for each book printed?

What is the cost to get started (before any books are printed)?

Equation: y=1250+25x

What is the change in the total cost for each book printed?

$25

What is the cost to get started (before any books are printed)?

$1250

$25

What is the cost to get started (before any books are printed)?

$1250

Which expression can be used to convert 22 Australian dollars to US dollars? Assume 1.2 Australian dollars equals 1 US dollar.

Answer: There are approximately 18 US dollars.

Step-by-step explanation:

Since we have given that

1 US dollar = 1.2 Australian dollars

We need to find the number of US dollar in 22 Australian dollars.

So, it becomes,

1 Australian dollar = 1÷1.2 = 0.83

22 Australian dollars is given by

22 × 0.83 = 18.34

Hence, there are approximately 18 US dollars.

I think it's 1.2 * 22 = 26.4

Joelle bought 20 lollipops and 6 bags of Doritos for a total cost of $8.20. She knows that each lollipop cost 25 cents and reasoned that two bags of chip must cost a little more than $1.00. Is this a reasonable guess? Why or why not?

I mean... I think it's a reasonable guess because not gonna lie- chips can get expensive. BUT- It doesn't really make sense because like, she bought so many lollipops. My brain isn't really functioning to do the math- but my best guess would beeeee... UNreasonble. I'm super super sorry if it's wrong. Math isn't my strong point, sorry. Have a nice day!

Answer:

no

Step-by-step explanation:

because 20×.25 = 5 so the lollipop cost $5.00 and then you only have 3.20 left over

On a number line, find the midpoint between -18 and 4.

The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.

How do I solve this problem 7 2/3 + n = 9 1/12

7 2/3+n=9 1/12

3•4=12

2•4=8

7 8/12+n = 9 1/12( these fractions have common denominators)

switch the operation (+ to -) and get the fraction by themselves

8/12-1/12=7/12

now subtract the whole numbers

9-7=2

finally answer 2 7/12

3•4=12

2•4=8

7 8/12+n = 9 1/12( these fractions have common denominators)

switch the operation (+ to -) and get the fraction by themselves

8/12-1/12=7/12

now subtract the whole numbers

9-7=2

finally answer 2 7/12

the tickets cost $41 each. He needs to buy a ticket for himself and other 2 family members. which is the best estimate of how much the tickets will cost total

1 ticket = $41

needs to buy = 3

3 tickets = $41 × 3

= $123

needs to buy = 3

3 tickets = $41 × 3

= $123

The howler monkeys at a zoo are fed a diet that contains 3.35 kcal/gram. Write a function g(x) that gives the mass of food in grams that a howler monkey must eat to obtain x kilocalories of energy.

The amount of energy that the given amount of food contains is the product of the given content per grams and the amount of food in grams.

For this item, we assume that g(x) is the total energy that the howler monkey needs to obtain and x is the amount of food in grams. From the presented concept in the first paragraph,

amount of energy = (3.35 kcal/gram) x (amount of food)

g(x) = 3.35x

For this item, we assume that g(x) is the total energy that the howler monkey needs to obtain and x is the amount of food in grams. From the presented concept in the first paragraph,

amount of energy = (3.35 kcal/gram) x (amount of food)

g(x) = 3.35x
