Answer:
The ratio of the surface areas and volume is 8((5y+5x) /25xy)
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes.
Let us assume that the radius =x
Radius r=5x/4
And the height =y
Height h= 5y/4
We know that the total surface area of a cylinder is
A total = 2πrh+2πr²
We can factor out 2πr
A total = 2πr(h+r)
The volume of a cylinder is given as
v= πr²h
The surface area and volume ratios
Can be expressed as
2πr(h+r)/πr²h= 2(h+r)/rh
= (2h+2r)/rh= 2h/rh + 2r/rh
= 2/r + 2/h
= 2(1/r + 1/h)
Substituting our value of x and y
For radius and height we have
= 2(1/5x/4 + 1/5y/4)
=2(4/5x + 4/5y)
=2*4(1/5x + 1/5y)
= 8 (5y+5x/25xy)
THat would be 5/6 * 4 = 20/6 = 3 1/3 hours jogging.
The "L"-shape would look like it fell backwards and was laying on the ground. The little leg of the L would be pointing up into the air.
A 90 degree counter clockwise turn means that it rotates left around the origin. It turns one half of half a turn, or 90 degrees.
Answer:
Step-by-step explanation:
A linear function is always a one-to-one function.
Switch y and x.
x = -8y + 1
-1/8x + 1/8 = f(x)
