Answer:
D, 0.19
Step-by-step explanation:
So first you add up all the candies
you’ll get 79 pieces of candy
So 4 pieces of green candy
So we can just subtract 4 from 79 you’ll get 75 pieces
It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount
Now there are 14 red pieces
So 14/75
Now simplify that and you’ll Get
0.18666666
Now round that, 0.19
V=1/3πr^2h
d=3.6 in.
r=1.8 in.
V=1/3×π×1.8^2×3
V≈10.1736 cubic inches. As a result, the volume of the funnel is 10.1736 cubic inches. Hope it help!
Probably the subsitution method
y=1/2x
subsitute that fr y
2x+3(1/2x)=28
2x+3/2x=28
times 2 both sides
4x+3x=56
7x=56
divide by 7 both sides
x=8
sub back
y=1/2x
y=1/2(8)
y=4
(x,y)
(8,4)
