Answer:
4.5 hours in minutes = 270
Every 45 minutes, bacteria triples
You start with 50
Divide 270 (total time) by 45 (every time bacteria triples)
270/45 = 6
36,450 bacteria

Given: It takes Hank 
minutes 
hours to mow a lawn. Penny can mow the same size lawn in 
minutes 
hours. Hank and Penny form a small lawn care company and have contracts for 
lawns of the same size previously mentioned.
To Find: How long should it take both of them working together to mow the lawns.
Solution:
Time taken by Hank to mow the lawn 
Time taken by Penny to mow the lawn 
Total lawns to be mowed 
Let time taken by Hank and Penny to mow one lawn 
time taken to mow lawns 
Hence it will take 
by Hank and Penny to mow lawns

Answer:
1.14x = 2x
x = (0.12)(1.14)x
Step-by-step explanation:
We are going to express the data in an equation form:
If <em>x </em>was the number of cases there was in 2000 ⇒<em>currently there are 1.14x </em>cases of measles.
But the question also tells us that the number of cases now is also 2 times what it was in 2000.
So we have that <u>1.14x = 2x</u>
<u />
It also tells us that the number of measles back in 2000 was 12% of what it is now.
<u>x = (.12) 1.14x</u>
<u />
We can't really solve these equations since the problem doesn't give us any more information (I am assuming there was another part of the problem before this one that wasn't written here).
If 45 + 47 = t, then t = 45 + 47.....correct
if 45 + 47 < t , then t = 45 + 47....incorrect
45 + 47 < t
92 < t .....this is saying that t is greater then 92
t = 45 + 47
t = 92...this is saying t is equal to 92 (not greater)
