When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88

1 answer:

6 0

Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!

Renee spent 1/8 of the day landscaping around the house. She spent half of the time pulling weeds. What fraction of the day did

Inga [223]

Answer:

The fraction of the day Rehee spent pulling weeds = 1/16

Step-by-step explanation:

Let us take the fraction representing a whole day to be a whole number - 1

Renee spent 1/8 of the day landscaping around the house.

This means she spent 1/8 X 1 landscaping around the house = 1/8

She spent half of the time pulling weeds.

This means she spent 1/2 of 1/8 of 1 landscaping around the house = 1/16

1/2 X 1/8 X 1 = 1/16

The fraction of the day Rehee spent pulling weeds = 1/16

Simplify (3a^4-2a^2+5-10)-(2a^4+4a^2+5a-2)

katrin [286]

Answer:

Step-by-step explanation:

3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)

as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm

I'm guessing that it is... soooo distribute the minus sign

= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2

= a^4 -6a^2 -8 :) voila that's your answer
