Keisha runs each lap in 8 minutes. she will run less than 7 laps today. what are the possible numbers of minutes she will run today?

Since she is going to run less than 7 laps, the most she can run is 48 minutes.

Step-by-step explanation:

This can be solved as a rule of three problem.

The most she can run is 6 laps, since she is going to run less than 7. For each lap, there are 8 minutes. How many minutes are there for 6 laps? So

1 lap - 8 minutes

6 laps - x minutes

x = 8*6 = 48 minutes.

Since she is going to run less than 7 laps, the most she can run is 48 minutes.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
