Noooo Linnkkkkkk Rodney ordered a large sub sandwich. He ate 1/4 of the sandwich on monday and 1/3 of it on tuesday. Which equation shows how to find how much of the sandwich Rodney ate ate in all?
A. 1/4 + _ = 1/3
B. 4/7 + 5/7 = _
C. 4/12 + 5/12 = _
D. 3/12 + 4/12 = _

Answers

Answer:

Step-by-step explanation:

3/12 simplified is 1/4, 4/12 simplified is 1/3. they want to know how much rodney ate total, so simply it's the same as 1/4 + 1/3 ;; just with common denominators so it is easier to solve.

edit: the __ represents the total on how much they ate.

The equation used to describe total amount of sandwich he ate will be

3 / 12 + 4 / 12 = 7 / 12.

What is an equation?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

It is given that:-

He ate 1/4 of the sandwich on Monday and 1/3 of it on Tuesday

So the equation to calculate the total amount of sandwiches he ate will be:-

= 1 / 4 + 1 / 3

We can also write the above equation as:-

= 3 / 12 + 4 / 12

= 7 / 12

Therefore the equation used to describe the total amount of sandwich he ate will be 3 / 12 + 4 / 12 = 7 / 12.

A restaurant found that 28% of its customers ordered salad and 35% ordered beef. What percent of the customers ordered something else?
(WHOEVER ANSWERS FIRST WILL GET BRAINLIEST, A THANKS, AND A 5 STAR REVIEW)

Answers

Answer:

37% ordered something else.

Step-by-step explanation:

First you add 28+35 and it will give you 63.

Then you will subtract 100 (the total percentage) by 63.

you will end up with 37.

add the percentage and it will be 37%.

Good Luck!! <3

28 + 35 = 63

100 - 63 = 27

27% ordered something else. Not sure if this question was supposed to be more complex, excuse me if I oversimplified it. Hope this helps!

Answer: The mean is 5

Step-by-step explanation:

If you add all of the numbers and divide by how much numbers there are (8), then you get 5. Then the mean absolute deviation is the number away from the mean.

So I will put the mean absolute deviation in order of the numbers

4 (1 away from mean), 3 (2 away from the mean), 4( 1 away from the mean), 5 (same number as the mean), 6 (1 away from the mean), 6(1 away from mean), 8 (3 away from mean), and, finally another 4 (1 away)

Your answer will be the third one.

Step-by-step explanation:

If you add up the numbers on top for the first, secnd, and fourth ones and divide that by the number ont he bottom, you will constantly get 6. However, for the third one, you'll get seven since 9+9 is 18 and 5+5 is 10. Add that up and you get 28, and divide that by 4 and you get 7, not 6. hope this helps!

Answer: (9+9+5+5)/4

Step-by-step explanation:

Because if you add all of the numbers on the numerator and divide by the denominator, all of them equal 6 except that one. So it doesn't belong
