Answer:
Fred's
Step-by-step explanation:
Igloo 1.75(60) + 75 = 180
Tasty 2(60) + 80 = 200
Fred's 1.25(60) + 90 = 151.25
Answer:
a) 20
Step-by-step explanation:
when we have an exponent of an exponent, we simply multiply them for the overall exponent.
so, we actually have
a^((1/4)×12) × b^((1/3)×12) = a³b⁴ = 5000
let's find the prime factors of 5000 :
5000 ÷ 2 = 2500
2500 ÷ 2 = 1250
1250 ÷ 2 = 625
625 ÷ 3 no
625 ÷ 5 = 125
125 ÷ 5 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1
so,
5000 = 2³ × 5⁴
so, a = 2, b = 5
a²b = 2²×5 = 4×5 = 20
Anything raised to the (1/2) power is a square root. (1/3) power is a cube root. (1/17) power is the seventeenth root. whenever you raise something to 1 over a number, the number beneath the 1 becomes the index of your radical (aka the little number above the square root line).
I don't see the answer choices, but 2 equations you could use to get eighteen would be:
9 × 2 = 18
OR
9 + 9 = 18
See? Twice a number is eighteen. You can use any of my equations to get eighteen

For the first year, Bob gets 12% on his first deposit: 1.12(5000). The second year, Bob adds 5000 and gets 12% on top of what he had at the end of the first year plus his extra 5000 deposit: 1.12(1.12(5000) + 5000), if you expand this you get 1.12*1.12*5000 + 1.12*5000.
You can see a pattern here, so let's factor out the 5000 and see what the full 8 years would be:
5000(1.12^8 + 1.12^7 + ... + 1.12^2 + 1.12). Everything in the parentheses comes to approx. 14.775656, multiplied by 5000 gives you 73,878.28.
So D) $73,878 is your answer.
