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
Blue whale
Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:
Therefore, the African elephant weighs 111.5 tons less than a blue whale.
Let the required point be (a,b)
The distance of (a,b) from (7,-2) is
=
But this distance needs to be betweem 50 & 60
So
Squaring all sides
2500 < (a-7)² + (b+2)² < 3600
Let a = 7
So we have
2500 < (b+2)² <3600
b+2 < 60 or b+2 > -60 => b <58 or b > -62
Also
b+2 >50 or b + 2 < -50 => b >48 or B < -52
Let us take one value of b < 58 say b = 50
So now we have the point as (7, 50)
The other point is (7,-2)
Distance between them
=
This is between 50 & 60
Hence one point which has a distance between 50 & 60 from the point (7,-2) is (7, 50)
