<u>Jerry:</u>

50 mins = 1 detailed car

1 min = 1/50 of the details

<u>Sally:</u>

60 mins = 1 detailed car

1 min = 1/60 of the details

<u>If they work together:</u>

1 min = 1/50 + 1/60 = 11/300 of the details

Total time needed:

300 ÷ 11 = 27.27 mins

Answer: They will need 27.27 mins if they worked together.

Which equation can be used to find the solution of (1/4)^y+1=64?
Ne4ueva [31]

Answer:

−y−1=3

Step-by-step explanation:

Which equation can be used to find the solution of (1/4)^y+1=64?

This can be solved by power of indices

(1/4)^(y+1)=64

(4^-1)^(y + 1)= 4^3

Note

(x^a)^b = x^ab

Hence:

4^(-1)(y + 1)= 4^3

4^-y - 1 = 4^3

Divide both sides by 4

−y−1=3

Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is

−y−1=3
