Answer:
It will take her 10.5 hours to read the book
Step-by-step explanation:
She averages 16 pages every 30 minutes. If you take 336 and divide it by 16, you get 21 hours. But since she is reading 16 pages every half hour, that wouldn be correct. If it is asking how many hours it will take her to read the book, you have to take 16 and multiply it by 2. Then you get 32. Then, do the equation again. 336 divided by 32 is 10.5. So, if she reads the entire book in one go, it will take her 10 and a half hours to read the entire book, or 10.5.
x = number of hours after 9 am (eg: x = 1 means 1 hr after 9 am, so 10 am)
f(x) = population count x hours after 9 am
f(1) = population count at 10 am (1 hour later)
f(2) = population count at 11 am (2 hrs after 9 am)
f(2) - f(1) represents the difference in population counts from 10 am to 11 am, or put another way, how much the population increased during that time interval.
Volume of a sphere is 4/3pi∗r3. r is half the diameter.
Answer:
The answer is: 11.2, 13 and 17.4
Step-by-step explanation:
The scale factor of 2 means that we will build a triangle with sides of double lenght than original one.
So sides will be
It should be 75×3=115 then 115×4=160 so 160 should be the answer!
