Step-by-step explanation:
Find w
V = lwh
V ÷ lh = w
V/lh = w
w = V/lh
Option → C
Answer:
7-2x=y
Step-by-step explanation:
When a point passes through a line it satisfies its equation
(X-x0 )m= y-y0
Slope = m = -2
(X-2 )(-2)=y-3
4-2x=y-3
7-2x=y
Answer:
15 x^8 y^3
Step-by-step explanation:
The area of a rectangle is given by
A = l*w where l is the length and w is the width
A = ( 5x^6 y^2) *( 3x^2 y)
= 15 x^(6+2) y^(2+1)
= 15 x^8 y^3
Answer:
Step-by-step explanation:
Let us assume that if possible in the group of 101, each had a different number of friends. Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.
Say P has 100 friends then P has all other persons as friends. In this case, there cannot be any one who has 0 friend. So a contradiction. Hence proved
Part ii: EVen if instead of 101, say n people are there same proof follows as
if different number of friends then they would be 0,1,2...n-1
If one person has n-1 friends then there cannot be any one who does not have any friend.
Thus same proof follows.
