Answer:
Step-by-step explanation:
Height doubles at every 30 seconds, so let's call n how many times it happens, and the t the total time:
n = t/30
If the height doubles one time, it is multiplied by 2, if it doubles 2 times, it's multiplied by 2², for n times, it is multiplied by 2ⁿ, so for an initial height equal to 3:

<u>Answer:</u>
- There is a 41.7% chance that you got a blue ball.
<u>Step-by-step explanation:</u>
<u>Total number of blue balls/Total number of balls x 100 = Chance of getting a blue ball</u>
- => 5/12 x 100
- => 5/6 x 50
- => 5/3 x 25
- => 125/3
- => 41.7
Hence, <u>there is a 41.7% chance that you got a blue ball.</u>
Hoped this helped.
Pages read by Arnold in 7 minutes = 3 pages
Pages read by Arnold in 1 minutes
= 3/7 pages
= 6/14 pages
Pages read by Brenda in 14 minutes = 8 pages
Pages read by Brenda in 1 minutes = 8/14 pages
(6/14) < (8/14)
So, speed of Arnold < speed of Brenda.
So, Brenda reads faster.
