4/4 + 3/4 +1/20
"multiply" 4/4 and 3/4 by 5 so that the denominators are the same:
20/20+15/20+1/20
= 36/20
= 1 6/20
= 1 3/15
= 1 1/5
Answer:
y=-6-10 x
Step-by-step explanation:
make y the subject
The volume of the remaining paint is:
V1 = (1/4) * (pi) * (r ^ 2) * (h)
Where,
r: radio
h: height
Substituting values we have:
V1 = (1/4) * (3.14) * (8 ^ 2) * (20)
V1 = 1004.8 cm ^ 3
The smallest can volume is:
V2 = pi * r ^ 2 * h
Substituting values:
V2 = (3.14) * 5 ^ 2 * h
Matching the volumes:
V2 = V1
(3.14) * 5 ^ 2 * h = 1004.8
Clearing h:
h = (1004.8) / ((3.14) * 5 ^ 2)
h = 12.8 cm
Answer:
The height of the smallest part of the paint is:
h = 12.8 cm
The angle is sin inverse 0.3535 which is around 21 degrees
