Bella can complete work alone in 120 minutes
Step-by-step explanation:
Ana and Bella together can complete the shoveling in 30 minutes.
They can do a part of work in 1 minute =
Ana can do work alone in 40 minutes
She can do part of work in 1 minute =
So, Bella can do a part of work in 1 minute =
=
Bella can do part of work in 1 minute
Bella can do whole work in minutes = 120
Hence Bella can complete work alone in 120 minutes

Answer: A^2</h3>
You subtract the exponents using the rule
(x^y)/(x^z) = x^(y-z)
This rule only applies if both bases are the same.
Answer:
5 words per minute.
Step-by-step explanation:
Everett types 25 words per minute, and Jacob types 20 words per minute.
The total pages in the book are 510.
Step-by-step explanation:
Lets say, the total pages are x
Mo read the book with following proportion.
Monday: 2/5.x
Pages left: 1.x - 2/5.x = 3/5.x
Tuesday: 1/2.x of 3/5.x = (1/2.x) . (3/5.x) = 3/10.x
Pages left: 3/5.x - 3/10.x = 3/10.x
Wednesday: 5/9.x of 3/10.x = (5/9.x) . (3/10.x) = 1/6.x
Thursday : ?
Lets say the total proportion is 1. The proportion of book read on Thursday can be calculated as:
1.x - 2/5.x - 3/10.x - 1/6.x = 2/15.x
Also given, Mo read 68 more pages on Tuesday than Wednesday.
Therefore,
3/10.x - 1/6.x = 68
2/15x = 68
x = 510
Therefore, the total pages in the book are 510.
