If s is the Riley`s sister`s age and Riley is 3 years older so Riley`s age is:
s/3 so the sum of their ages is:
s + s/3 = 4s/3 :)))
i hope this is helpful
have a nice day
3 inches and 2 inches, 6÷3 & 9÷3.
12×3=36 so divide 6 by 3 and 9 by 3
Answer:
j=76 and k=65
Step-by-step explanation:


Differentiate both sides with respect to

:

When

, you have

For part (b), we now assume that

and

are functions of an independent variable, which we'll call

(for time). Now differentiating both sides with respect to

, we have

where the chain rule is used on the right side. We're told that

is decreasing at a constant rate of 0.1 units/second, which translates to

. So when

, you have



where the unit is again units/second.
Yasim is Albert who ran the race at a time that was 15.7 seconds shorter, So, Yasim is the student who improved the most by decreasing the time needed to run the race.
<h2>Given that,</h2>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
<h3>We have to
find,</h3>
Which student improved the most by decreasing the time needed to run the race?
<h3>
According to the
question,</h3>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
In the given option Yasim has the lowest value of the time which is -37.5 seconds.
Yasim was the most improved student because Yasim ran the second race in a time that was 37.4 seconds shorter than the first race.
Following Yasim is Albert who ran the race at a time that was 15.7 seconds shorter.
At the third place in improvement is Cody who actually was worse off than the first race along with the 4th place Hannah.
Hence, Yasim students improved the most by decreasing the time needed to run the race.
