Answer: ? = 0.14
Step-by-step explanation:
So you need to find the value that fits the question mark. This means you have to get it by itself.
To start you subtract 0.4 from 0.546, which equals .146. Then you subtract 0.006 from 0.146 to get 0.14
What it looks like mathematically :
0.546 = 0.4 + ? + 0.006
0.146= ? + 0.006
0.14=?

Answer:
Ig it's 734. I did l×w for the curve and 1/2×4×4.
We have been given that the speed of elephants is 5km/h east and his speed is 41km/h west.
We have to find after how long will he be 13km from the herd.
Since the biologist is going to the west and the elephants towards east, their relative speed will be calculated by adding their respective speeds.
So final their relative speed will be:
= 5 km/h + 41 km/h
= 46 km/h
Now we want their distance to be 13 km and we have calculated relative speed as 46 km/h.
So using formula :
Speed = Distance / Time,
We calculate time as :
= Distance / Speed
= 13 / 46
= 0.28 hours
= 16.8 minutes.
So after 16.8 minutes, biologist will be 13 km away from the herd.
