Aweb site goes viral. the number of users triples each day. what is the constant percentage increase each day?

We know that the number of users triple each day

Let number of users on day 1 be x

⇒ Users on day 2 = = 3x

and Users on day 3 = = 9x

And so on...

% Increase in users from day 1 to day 2 =

⇒ % Increase in users from day 1 to day 2 =

⇒ % Increase in users from day 1 to day 2 =

⇒ % Increase in users from day 1 to day 2 = 200%

Similarly,

% Increase in users from day 2 to day 3 =

⇒ % Increase in users from day 2 to day 3 =

⇒ % Increase in users from day 2 to day 3 =

⇒ % Increase in users from day 2 to day 3 = 200%

Hence, we can see that the percentage increase each day is 200%

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
