Answer:Answer: 175 %
Step-by-step explanation:
Given : A school year is 4 quarters.
To find : what percent of a school year is 7 quarters.
The percentage of a school year is 7 quarters will be given by :-
Since a school is 4 quarters , then
The percentage of a school year is 7 quarters will be :
Hence, the percent of a school year is 7 quarters = 175 %
The scale factor is 4 (10/2.5).
Each side has increased by a factor of 4. Think of it logically, if the original rectangle had sides of 1,1,1/4,1/4, the perimeter would add to 2.5. In order to get the sides to add up to 10, each of the sides would need to be multiplied by 4. Then our sides would measure 4,4,1,1 with a perimeter of 10.
In order to get who was right we need to solve the expression:
2a^2b(-2ab^3)^-2
The above can be written as fraction to get:
(2a^2b)/(-2ab^3)^2
=(2a^2b)/(4a^2b^6)
=1/2(a^(2-2)b^(1-6))
=1/2a^0b^-5
=1/2b^(-5)
This implies that neither of the was right
The answer for this question is 12 56
