Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in

Answer:



Step-by-step explanation:
Let
x----> the length of the rectangular garden
y---> the width of the rectangular garden
we know that
The perimeter of the rectangle is equal to

we have

so

simplify

 ------> equation A
------> equation A
Remember that the area of rectangle is equal to
 ----> equation B
 ----> equation B
substitute equation A in equation B
 
 
 ----> this is a vertical parabola open downward
----> this is a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex is the maximum area
The x-coordinate of the vertex is the length side of the rectangle that maximize the area
using a graphing tool
The vertex is the point 
see the attached figure
so

Find the value of y

The garden is a square
the area is equal to
 ----> is equal to the y-coordinate of the vertex is correct
 ----> is equal to the y-coordinate of the vertex is correct
 
        
             
        
        
        
Answer:
2/3
Step-by-step explanation:
There are 6 different letters and 4 of them are consonants, so: 
4/6 simplify it by 2:
