it is
Well,
In 1 hour, Tim painted 1/6th of the room.
In 1 hour, Ben painted 1/4th of the room
1/6+1/4
Make them both have a common denominator: 1/6=2/12 and 1/4=3/12
In 1 hour, they can paint 5/12th of the room.
Like in the beginning, I flipped the numbers 6 and 4 to 1/6 and 1/4 to get how much painting they did in 1 hour.
If going to flip the fraction 5/12 to 12/5 to get how much painting they can do in all. Make sense?
12/5 is 2.4, which is 2 hours and 24 minutes.
Hope I helped!
<u>Step-by-step explanation:</u>
<u>Here </u> ,There are no options given to choose which number is a cube root between 7 & 8 . So below provided answer is way to choose which numbers have cube root between 7 & 8 .
Here , We have to find that Which number has a cube root between 7 and 8 . Let's find out :
We know that ,
![\sqrt[3]{343} = 7\\\sqrt[3]{512} = 8](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B343%7D%20%20%3D%207%5C%5C%5Csqrt%5B3%5D%7B512%7D%20%20%3D%208)
So , the number which have cube root between 7 & 8 will surely lie in between of 343 & 512 . Suppose the numbers which which have cube root between 7 & 8 are
, So these numbers lie between 7 & 8 i.e.
⇒ 
Therefore, all the numbers which lies between 343 and 512 or
, have a cube root between 7 & 8 .
Answer:
8
Step-by-step explanation:
(5*2)+(2*5)-12=
10+10-12=
20-12=
8
