John is w years old. His sister is 16 years old and his brother is twice johns age all three siblings have a total age of 31
Kisachek [45]

Answer:

Step-by-step explanation:

John's age = w

His brother's age = 2*w  = 2w

His sister's age = 16 years

Total age of all siblings = 31

w + 16 + 2w = 31

w + 2w + 16 = 31

Combine like terms

      3w + 16 = 31

Subtract 16 from both sides

    3w          = 31 - 16

              3w = 15

                w = 15/3

               w = 5

\boxed{\text{John's age = 5 years }}

His brother's age = 2w

                            = 2*5

                            = 10

\boxed{\text{John's brother's age = 10 years}}

The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee
Lunna [17]

Answer:

=13.73 ft²

Step-by-step explanation:

The diameter of the largest possible circle that can be cut out of  a square is equal to the length of the side of the square.

Therefore the diameter of the circle cut from a square of side 8ft =8ft

r=4ft

Area of the remaining board= Area of square- area of circle

=side²-πr²

=8²-π×4²

=64-16π

=13.73 ft²
