12=24-y <br><br><br>help me pleaseee​
vitfil [10]

Answer:

y=12

Step-by-step explanation:

12=24-y

step 1

subtract each side by 24

24-24 cancels out

12-24=-12

now we have

-y=-12

we now have to divide by -1

-1/-1=1

-12/-1=12

so we can conclude that y=12

5. What is the approximate height of the cylinder?
boyakko [2]

Answer:

Height of the cylinder is 1ft

Step-by-step explanation:

Data ;

Volume = 314ft³

Assuming radius = 10ft

Height = ?

π = 3.14

Volume of a cylinder = πr²h

r = radius

h = height of the cylinder

Vol = πr²h

314 = 3.14 × 10² × h

314 = 314h

Solve for h,

h = 314 / 314

h = 1ft

The height of the cylinder is 1ft.

Help I don’t get it
Fittoniya [83]

Answer:

ok so.  Your answer is that the population grew by about 3% (1,722,862 people)

Step-by-step explanation:

You would just solve 53,594,378 by 55,317,240.  You would get a number right around 96.88 so you would round up to 96.9 or 97.  From there, you would subtract 100-97 or 100-96.9 to get 3 or 3.1, that is how you know what percentage something grew or shrank by. :) hope this helps you
