Answer:
The sum is 1575.
Step-by-step explanation:
Consider the provided information.
It is given that positive integers smaller than 1000 and that can be written in the form 
Where n is integer that means the value of n can be a positive number or a negative number.
For n = 0

For n=-1

For n=-2

For n = -3 the obtained number is not an integer.
Now consider the positive value of n.
For n=1

For n=2

For n=3

For n=4 the obtained number is greater than 1000.
Now add all the numbers.

Hence, the sum is 1575.
Let
....(1)
Multiply both sides of equation (1) by 10.
.... (2)
Multiply both sides of equation (1) by 100.
... (3)
Subtract equation (2) from equation (3)



Hence, the required fraction form is
.... Answer.
Answer:
The mass of the Blue whale is 200 times the mass of the cow
Step-by-step explanation:
Given
Mass of Cow = 9 * 10² kg
Mass of Blue Whale = 1.8 * 10⁵ kg
Required
Determine the relationship between both weights
Represent the mass of the cow with C and the mass of the whale with B






Divide the bigger weight by the smaller weight



Multiply both sides by C



<em>From the expression above, it can be concluded that the mass of the Blue whale is 200 times the mass of the cow</em>
