The oldest child in a family of four children is twice as old as the yougest. The two middle children are 12 and 16 years old. If the average age of the children is 15.25 , how old is the youngest child?

Answers

four children average is 15.25 so ages must add to 61
61-12-16=33
11 and 22 go into 33
Youngest is 11

The age of the youngest child will be 11 years old.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The oldest child in a family of four children is twice as old as the youngest.

Let x be the age of the youngest child and y be the age of the oldest child. Then the equation is given as,

y = 2x   ...1

The two middle children are 12 and 16 years old. If the average age of the children is 15.25. Then the equation is given as,

(x + 12 + 16 + y) / 4 = 15.25

x + y = 33  ...2

From equations 1 and 2, then we have

x + 2x = 33

3x = 33

x = 11

The age of the youngest child will be 11 years old.

Answer:

area = 2106

perimeter = 210

Step-by-step explanation:

Step-by-step explanation:

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ  = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ  = (6√5) / 1

12/sinθ  = (6√5)   (rearranging)

12 ÷ (6√5)  = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5   (moving radical to numerator by multiplying by √5/√5)

= 2 / √5     x     √5/√5

= 2√5 / 5

= (2/5)√5
