The distance a bike travels varies directly as the amount of time the bike has been ridden. Angela is riding her bike. If she travels a distance of 60 miles in 2 hours, how far has Angela traveled in 7 hours? A. 60 miles B. 37 miles C. 210 miles D. 420 miles

C. 210 miles

Step-by-step explanation:

60 miles in 2 hours => 30 miles per hour

7 * 30 = 210 => C. 210 miles

This is if she maintained a constant speed, and did not make any stops.

C) 210 miles

Step-by-step explanation:

60/2   (find the distance ridden in one hour)

=30/hour

30*7  (how long she's ridden in 7 hours)

=210

5050 i think

step-by-step explanation:

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
