<span>The equation is pretty straightforward. Basically, if 10^13 bacteria multiplies in 100 hours. We seek to know how many bacteria multiply per hour.
So if 10^13 bacteria mulitply in 100 hours
Then X bacteria multiply in an hour.
Hence X bacteria * 100 hours = 10 ^13 bacteria * 1 hour.
X = 10 ^13 * 1 / 100= 10^(13-2) 10^11. Basically, 10^11 bacterias multiply in an hour.</span>
Answer: 5/6
Step-by-step explanation:
All we need do is to try to change 50 minutes to hour.
Remember that 60 minutes make 1 hour , so we need to find 50 minutes out of 1 hour , that is 50 minutes out of 60 minutes. Which is 50/60. Therefore:
50 minutes is 50/60 fraction of an hour
50/ 60 is the same as 5/6 in reduced form
Answer: b. y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
time spent on history homework: 20 minutes
time spent on each math problem: 2 minutes
math problem : x
total time spent :y
So, we have to multiply each math problem (x) by the time spent on each math problem and add the 20 minutes spent on history homework.
The expression obtained is equal to the total time spent
Mathematically speaking:
y=2x+20
x can be any real number greater than or equal to 0, ( it would be 0 if there aren't any math problems)
and y is any real number greater than or equal to 20. ( 20 minutes is the minimum time spent if there aren't any math problems)
