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.

Does anyone know the answer?
FromTheMoon [43]

Answer:

AB = 4.41

Step-by-step explanation:

→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.

<u>→Set it up, like so:</u>

<u />cos25=\frac{4}{x}

<u>→To get rid of the x in the denominator, multiply everything by x:</u>

<u />x(cos25=\frac{4}{x})

xcos25 = 4

<u>→Divide both sides by cos25:</u>

x = 4.413

<u>→Round to nearest hundredth:</u>

x = 4.41
