The table shows the average weight of animals. How many more tons does a blue whale weigh than an African elephant? Explain how
AVprozaik [17]

Answer:

The African elephant weighs <u>111.5 tons</u> less than a blue whale.

Step-by-step explanation:

Given:

Animal                         Weight(pounds)

African Elephant            15,000

Blue Whale                   238,000

Now, to find the weight of how more tons does a blue whale weigh than an African elephant.

As given, 1 ton = 2,000 pounds.

So, to convert the weight from pound to tons by dividing:

African elephant =15000\div 2000=7.5\ tons.

Blue whale =238000\div 2000=119\ tons.

Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:

Blue\ whale - African\ elephant

=119 tons-7.5tons

=111.5\ tons

Therefore, the African elephant weighs 111.5 tons less than a blue whale.

The height of a cone is twice the radius of its base. What expression represents the volume of the cone, in cubic units?
dsp73

Answer:

A

Step-by-step explanation:

The general formula for the volume of a right cone is as follows (also see attached):

V = (1/3) π r² h; where r = radius of base and h = height

In this case, it is given that r = x

also given :

height = 2 (base radius)

or

h = 2x.

Hence the formula becomes:

V = (1/3) π r² h

V = (1/3) π x² (2x)

V = (2/3) π x³  (answer A)
