Bob has three pennies. Betty has three times as many pennies as bob. Bill has three times as many pennies as Betty. Barb has three times as many pennies as bill. Write a power to represent the number of pennies that barb has.

barb has 3⁴ pennies

Step-by-step explanation:

We are told that ;

Bob has 3 pennies = 3

Betty has three times as many pennies as bob = 3 × 3 = 3²

Bill has three times as many pennies as Betty = 3 × 3² = 3³

Barb has three times as many pennies as bill = 3 × 3³ = 3⁴

Thus,barb has 3⁴ pennies

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
