Answer:
10.625 seconds
Step-by-step explanation:
distance = speed · time
We want the total of all distances to be zero.
(-3.5)(90) +(2.2)(120) +(4.8)t = 0
-315 +264 +4.8t = 0 . . . . . simplify
-51 +4.8t = 0 . . . . . . . . . . . simplify more
-10.625 +t = 0 . . . . . . . . . .divide by 4.8
t = 10.625 . . . . . . . . . . . . . add 10.625
It will take the scientist 10.625 seconds to reach sea level.
When solving a real world problem to find a person’s age, a negative solution won't make sense because we can't have a negative age in this type of scenario.
<h3>What is Age?</h3>
This is defined as the amount or the duration of time an individual or organism has existed in a certain environment and is usually calculated from the day the person was given birth to.
When solving for age , a negative solution doesn't make sense because every organism has a positive age value and not a negative one. This is because as time goes on, we experience various forms of growth and ageing.
This is therefore the reason why it was chosen as the most appropriate choice.

Answer:
40%
Step-by-step explanation:
You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 6 and 15 using
GCF(6,15) = 3
6÷315÷3=25
We know that
25
is the same as
2÷5
Then using
Long Division for 2 divided by 5
gives us
0.4
Converting our number to a percentage:
0.4×100
=40%
