first of all the miniutes is not a linar function cause the first miniutes is 45 the 12 minuets later 57 but 11 minuets later 68 minuets so the minuets is not linear

what i did to find the credit was that i took 24.15-1.59 wich gave me 22.59 then i did 22.59-1.59 which gave me 21.03 if that is not correct

The average weight of the class of 35 students was 45 KG. with the admission of a new student the average weight came down to 44

melamori03 [73]

The weight of the new student is 27 kg.

Average weight

= total weight ÷total number of students

<h3>1) Define variables</h3>

Let the total weight of the 35 students be y kg and the weight of the new student be x kg.

<h3>2) Find the total weight of the 35 students</h3>

y= 35(45)

y= 1575 kg

<h3>3) Write an expression for average weight of students after the addition of the new student</h3>

New total number of students

= 35 +1

= 36

Total weight

= total weight of 35 students +weight of new students

= y +x

$44.5 = \frac{y + x}{36}$

<h3>4) Substitute the value of y</h3>

$44.5 = \frac{1575 + x}{36}$

<h3>5) Solve for x</h3>

36(44.5)= 1575 +x

1602= x +1575

<em>Subtract 1575 from both sides:</em>

x= 1602 -1575

x= 27

Thus, the weight of the new student is 27 kg.

Answer:

The level was 402.7ft. at the end of two weeks.

Step-by-step explanation:

First, we need to find the amount of decrease for the first week.

520 x 0.12 = 62.4

Now, we subtract the change for the first week.

520 - 62.4 = 457.6

Next, we find the change for the second week.

457.6 x 0.12 = 54.912

Then, we subtract the change for the second week.

457.6 - 54.912 = 402.688

And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
