C, 90 years
Step-by-step explanation:
You just do 6 times 5, the amount of people, and find out the amount of years.
Answer:

Since the measurement can't be negative the correct answer for this case would be 
Step-by-step explanation:
Let's assume that the figure attached illustrate the situation.
For this case the we know that the original area given by:

And we know that the initial area is a half of the entire area in red
, so then:

And we know that the area for a rectangular pieces is the length multiplied by the width so we have this:

We multiply both terms using algebra and the distributive property and we got:

And we can rewrite the expression like this:

And we can solve this using the quadratic formula given by:

Where
if we replace we got:

And the two possible solutions are then:

Since the measurement can't be negative the correct answer for this case would be 
1. If y<span>ou have jogged 5 miles from the park at a rate of r miles per hour, then the time you need to do this is

hours (

, where S is distance, v-speed and t-time).
</span>
2. W<span>hen you run back to the park, your average speed increases by 1 mph and become r+1 mph.
</span>
3. I<span>t takes

hours to jog 5 miles back to the park</span>
4. T<span>he total jogging time T is

hours.</span>
<span />
5. If you jogged away from the park at an average speed of 4 miles per hour, then r+1=4 and r=3. The expression

will take look
<span>

hours.</span>
Answer and Step-by-step explanation:
The least common multiple (LCM) of 15 and 24 can be found using the prime factorization of 15 and 24 which is...
The prime factorization of 15 is... 3 x 5.
The prime factorization of 24 is... 2 x 2 x 2 x 3.
Eliminate the duplicate factors of the two, then multiply them once with the remaining factors of the lists to get LCM (15,15) = 120.
