Answer:
126 minutes or 2 hours and 6 minutes
Step-by-step explanation:
Find how long it took her to swim one lap
1 hour and 30 minutes = 90 minutes
90/5 = 18
This means it took her 18 mins to swim each lap
18 · 7 = 126
It took her 126 minutes/2 hours and 6 minutes to swim 7 laps
Given that the sequence is:
1,2,4,8,32
the recursive formula will be found as follows:
first term is=1
the sequence can be written as:
1,2,4,8,32
=(1*2^0),(1*2^1),(1*2^2),(1*2^3),(1*2^4)
thus the recursive formula will be
an=a1(r)^(n-1)
plugging the values we get:
an=1(2)^(n-1)
Answer:
Step-by-step explanation:
Both expression are the same :
14 = 2(x + 3)
By expansion :
14 = 2*x + 2*3
14 = 2x + 6
Hence ;
Both expression are the same
Weight of one circle :
Final weight on both sides are equal:
Weight on Left hand side = 14
Weight on right hand side = 3*x + 3*x
Weight on Left hand side = Weight on right hand side
14 = 3x + 3x
14 = 6x
x = 14 / 6
x = 2.333
Answer:
700 miles driven in a day
Step-by-step explanation:
Create an equation to represent the situation, where x is the number of miles.
0.8x + 120 = 0.9x + 50
Solve for x:
120 = 0.1x + 50
70 = 0.1x
700 = x
So, the rental costs will be the same at 700 miles driven in a day.
