Its not 70 its 56, because you have to see how many minutes it takes for 1 to do 4 walls which would be 40*8.
Then you have to see if how many minutes its take a person to do one wall which is 8*40/4 from getting the amount of the 1 person doing 4 walls and get 80.
Then you need to see how many walls a person can paint 7 walls out of 10 people.So, we know how many minutes for each wall which is 80 and then multiply it by 7 to get 560 and divide it by 10 to get a product of 56.
Answer:
11/61
Step-by-step explanation:
cos b = adj side/hypotenuse
=11/61
It works because even if the numbers are broken apart, you are still multiplying the numbers by their values, it's only different because once broken apart, it's in expanded form instead of standard form. It also makes multiplication easier since you don't have to deal with such large numbers.
Answer:
School needs to collect at least 144 box tops each day to meet their goal.
Step-by-step explanation:
The total requirement of box tops = 2,000
The number of box tops they have already received = 872
So, the box tops left = Total number required- Number of tops received
=2,000 - 872
= 1,128 box tops are left so far.
Number of days left = 8
So, number of minimum tops needed each day = ![\frac{\textrm{Total tops required}}{\textrm{Number of days left}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20tops%20required%7D%7D%7B%5Ctextrm%7BNumber%20of%20days%20left%7D%7D)
= ![\frac{1128}{8} = 141](https://tex.z-dn.net/?f=%5Cfrac%7B1128%7D%7B8%7D%20%3D%20141)
Hence, they need to collect at least 144 box tops each day to meet their goal.
