Answer:
2097150
Step-by-step explanation:
sum=(2(1-1048576))/(1-2)
((5x2)+5.5+(6x3)+6.5+(7x5)+(7.5x4)+(8x4))/20
137/20
= 6.85
Answer: 110 horses
Step-by-step explanation:
Given
An average adult horse needs two fifth bale of hay
The farm has 44 bales of hay
Suppose n horses can be fed by the available bales of hay
So, we can write

Answer:
B. Perimeter of a square and
C. Side length of a square
Step-by-step explanation:
if n= side length of square then
- Area of square is

- Perimeter of a square is 4×n
- diagonal length of a square is
× n
Thus,
Perimeter of square can be expressed as
×diagonal length of a square
Side length of a square can be expressed as
×diagonal length of a square
but Area of square is
×n×diagonal length of a square
As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
