Ok....
Simplified would be 12.40
Squared would be 153.99 or fraction form would be 83 + 12

Answer:
y=5/4x
Step-by-step explanation:
(A fraction)
Answer:
can be expressed as decimal: 0.025
s= 1.025* $250
= $256.25
after 8 years
s= $250* 1.025^8
~$304.6
earned $54.6
Step-by-step explanation:
2 and a half is equivilant to 2.5
because it is a % (out of 100) move the decimal 2 places down
2.5-->0.25-->0.025
so can be expressed as decimal: 0.025
interest after 1 year is:
original amount of money * (interest rate+1.0)
+1 because you are adding on to 100%. you already have 100%. if it was just the interest rate, the amount of money would go down.
so
s= 1.025* $250
=1.025* 250
=256.25
interest after 8 years,
that means you have to take the original, and multiply it by the interest rate, then the new original multiply by intrest rate a total of 8 times
to do this use an exponent, because exponents base the total off the total before them. if that makes any sense srry
s= $250* 1.025^8
~$304.6 (I used calculator)
to get her earnings, subtract the new amount of money with her original amount of money
304.6-250
=54.6
$54.6
hope this helps

Answer:
Step-by-step explanation:
We want to study the fuel consumption of each car, i.e the amount of mile per gallon the cars will consume
Step one:
given data:
First car
distance covered= 41 1/2 = 41.5miles
amount of gallons= 1 1/4= 1.25gal
the miles per gallons= 41.5/1.25=33.2 miles per gallon
Second car
distance covered= 21 3/5= 21.6miles
amount of gallons=4/5= 0.8gal
the miles per gallons= 21.6/0.8=27 miles per gallon
1. Therefore the unit rate of
the first car = 33.2 miles per gallon
the second car=27 miles per gallon
2. the first car can travel a greater distance on 1 gallon of gasoline
