Question

26. Higher Order Thinking A mother

manatee, pictured to the right, is three
times as long as her baby manatee.
a. How long is her baby manatee? Write
and solve an equation.
12 feet
b. If a blue whale is 9 times as long as the
manatee shown, how much longer is
a blue whale than the manatee? Write
and solve equations.

Answer 1

a) Hence the Baby Manatee is 4 feet long.

b) Hence the Length of blue whale is 108 feet.

Explanation:

Given:

Length of Mother manatee = 12 feet.

Now given that:

A mother manatee is three times as long as her baby manatee.

Let the length of baby manatee be 'x'.

So equation can be framed as

`3x=12`

hence the equation is
`3x=12`.

Solving the equation we get;

Dividing both side by 3 using Division property of equality we get;

`(3x)/(3)=(12)/(3)\\ \\x=4\ feet`

a) Hence the Baby Manatee is 4 feet long.

Solving for part b we get;

Given:

If a blue whale is 9 times as long as the mother manatee

Hence equation can be framed as;

Length of blue whale is =
`9 * \textrm{Length of Mother manatee}`

Length of blue whale is =
`9* 12 =108\ feet`

b) Hence the Length of blue whale is 108 feet.
