Sarah colored 1/2 of her paper green. Melanie folded her paper into eight. How many sections should Melanie color to make her paper look just like sara's?

Answers

Answer 1

Answer:

Answer: She should color 4 sections to look like Sara's.

Step-by-step explanation:

Since we have given that

Part of paper of Sarah coloured green is given by

$(1)/(2)$

Number of times Melanie folded her paper = 8

We need to find the "Number of sections Melanie should color to make her paper look just like Sara":

Number of sections Melanie should color is given by

$(1)/(2)* 8\n\n=4$

Hence, She should color 4 sections to look like Sara's.

What is 70/6 times 18/4 in simplest form

Answers

70/6 × 18/4

70 * 18/6*4. cross out 18 and 6.

= 70*3/4

= 35 * 2 * 3/ 2*2

= 35*3/2

= 105/2

= 52.5

OR

52 1/2.

70/6*18/4 = 105/2=52.5 52.5= $\boxed{32 (1)/(2)} \n$

What is the sum of any rational number and it's opposite

Answers

To figure out this problem, you can look at formulas, or you can try out a few problems. There are many people that prefer one or the other in my class, so I will show you both. :)

Before I show you either of these, I'm going to define rational numbers and explain some things so that you can understand why we do what we do. Make sure to remember things like this because when you get to algebra (I'm in algebra), you need to know all of this stuff! :)

A rational number is any number that can be written in a over b form (a/b) or as a fraction. A rational number can be positive or negative because you can put positive and negative numbers into a fraction. Decimals can also be rational numbers because things such as .3 can be written as 3/10. So, depending on what number you have, there is always an opposite.

To find an opposite number, you have to basically find the absolute value (how far the number is from zero), double that number, and add it from the original number. Or, if you want to make it worlds easier, you can just make the number the opposite inverse. So, if it is -4, the opposite is 4. If the number is 7, then the opposite is -7. What is the sum between both of those examples? Zero.

Here is the formula: a+(-a)=0, (-a)+a=0
Here is some examples: (-5)+5=0, 8+(-8)=0

Thanks so much for the opportunity to answer your question. I hope this helped! :)

It's 0.

$a+(-a)=a-a=0$

What is the median of, 18, 16, 13, 10, 9.5, 8.5, 7.5, and six????

Answers

you have to fist pot them in order 6, 7.5, 8.5, 9.5, 10, 13, 16, 18

so the middle numbers are 9.5 and 10

add them together 9.5+10=19.5 then divide by 2 so 19.5/2=9.75 that is you answer

18 |16 | 13 | 10 | 9.5 | 8.5 | 7.5 | 6

9.75 is the FINAL answer
