You are getting ready for a family vacation. you decide to download as many movies as possible before leaving for the road trip. if each movie takes 1 2/5 hours to download, and you downloaded for 5 1/4, how many movies did you download. explain i need !

If all movies took the same time to download (unlikely), you could download (5 1/4) / (1 2/5) movies

= (21/4) / (7/5) = (21/4)*(5/7) = 15/4 = 3 3/4 movies.

If it takes 1 2 5 hours to download 1 movie, then in 5 1 4 hours, you will download 4 movies.

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

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
