Explain how you know Elena made a mistake based on her solution.
Elena is trying to figure out how many movies she can download to
her hard drive. The hard drive is supposed to hold 500 gigabytes
of data, but 58 gigabytes are already taken up by other files. Each
movie is 8 gigabytes, Elena wrote the inequality 8x + 58 2 500 and
solved it to find the solution x > 55.25.

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
