One way to solve it is writing two equations based on the info so
y = 5x + 10 for members
y = 6x for nonmembers
(the + 10 isn't included in the second equation because nonmembers won't pay a membership fee)
and to find their intersection point (where the values will be the same), you just set them equal to each other:
5x + 10 = 6x
subtract 5x
x = 10 classes
this is an isosceles triangle... meaning that the two base angles will be equal.
180 - 38 = 142
142 / 2 = 71
x = 71
4cm•2=8cm which is the length of the red paper so therefore Red paper= 4cmx8cm.
Then your going to take 3cm-4cm= 1cm
Next your going to solve for 7cm-8cm=1cm
Which leaves you with an answer of 1cmx1cm more of visible red paper.
Step-by-step explanation:
We know that
Radius = Diameter/2
=> Radius = 2/2
=> Radius = 1 in
Now,
Volume of cylinder = πr²h
=> π × (1)² × 9
=> 9π in³
Since it is filled ⅔ of the volume
So,
Water to be putted = ⅔ × 9π = 6π in³
