Adam’s father is 3 times as old as Adam. Two years ago, Adam was 15 years old. How old will his father be in 5 years?
1 answer:
Answer: 56 years
Step-by-step explanation:
Let Adam's age be , since the father is 3 times as old as him , then the father will be
.
Two years ago
Adam =
Father =
since Adam was 15 years old 2 years ago , this means that
add 2 to both sides
Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.
In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time

Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
d = distance
= coordinates of the first point
= coordinates of the second point
The formula to calculate the volume of a cone is:
So, replace radius = 3in and h = 8 in.
The result is: [1/3] π (3in)^2 (8in) = [1/3]π(9)(8) in^3 = 24 π in^3
Answer: option b. 24 π in^3
So, replace radius = 3in and h = 8 in.
The result is: [1/3] π (3in)^2 (8in) = [1/3]π(9)(8) in^3 = 24 π in^3
Answer: option b. 24 π in^3
