Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.
Answer: probability 0.01 %
Step-by-step explanation:
P(A) = 10% = 10/100 = 0.10
pick two people -
= P(A).P(A)
= 0.10 times 0.10
= 0.01
probability = 0.01
The answer is 42kg/45kg or 14kg/15kg
