Answer:
Sailboat A won the race, and it was going 8 feet per second.
Step-by-step explanation:
Sailboat A was traveling at 40 feet per every 5 seconds, so, to find how many feet it was going per second, we would do 40 feet/5 seconds, which is 8 feet.
Sailboat B was traveling at 56 feet per every 8 seconds, so we use the same method. 56 feet/8 seconds is 7 feet.
So, Sailboat A won because it was going faster! :)
Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
94/120=0.7833333333333333......

<span>Let x = # of rides
Plan A: 10 + 3x
Plan B: 20 + x
if x < 5 rides then plan A is better buy
if x = 5 both plans are the same
if x > 5 then plan B is the best buy
Prove:
x = 6 (rides)
plan A: </span>10 + 3x = 10 + 3(6) = 10+18 = $28
plan B: 20 + x = 20 + 6 = $26
