Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h
Answer:
14
Step-by-step explanation:
Given that:
Each fish bowl to have pebbles of weight equivalent to = 
Total pounds of pebbles that Timothy can use = 
To find:
The greatest value of Total number of fish bowls that Timothy can fill ?
Solution:
First of all, we need to convert mixed fraction into a fractional number and then we also need to see division of two fractions.
Formula:

Now, the given mixed fraction can be converted to fractional number as:

Now, To find the total number of fish bowls that can be filled, we need to divide the total number of pounds with number of pounds of pebbles in each fish bowl.
So, the answer is:

<em>14</em> number of fish bowls can be filled.

Trying to factor as a Difference of Squares
2.1 Factoring: 25a2-b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (5a + b) • (5a - b)
