Answer:
56
Step-by-step explanation:
80 x (7 / 10) = 56
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.
Answer:
The answer to your question is: 99 m²
Step-by-step explanation:
Data
height = 11 m
area of the square base = 9 m²
Formula
Volume of a right rectangular prism = area of the base x height
= 11 x 9 substitution
= 99 m²
The term with degree 4 is
.
The coefficient of the term is the constant number that is being multiplied with the variable of the term. In case of
, the variable is x raised to the power 4 and the constant term that is being multiplied to the variable is 5.
So the coefficient of of term of degree 4 is 5.
Thus correct answer is option D
