Answer:
After 140 days
Step-by-step explanation:
The next time both plants will be watered together is simply the LCM of 10 and 14.
10 has multiples: 10, 20, 30, 40 , 50 ....
14 has multiples: 14, 28, 42, 56 ....
When will they next be equal?? That's the LCM.
We first do prime factorization of the numbers and then multiply each factor the greatest number of times it occurs in either number.
<u>Prime Factorization</u>
10 = 2 * 5
14 = 2 * 7
So,
LCM = 2^2 * 5 * 7 = 140
After 140 days
I believe you would need to divide 123.75 by 7.50.
The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
Answer:
38.5 is your answer of this questions
Zoe will have to run 11.9 miles
Given that Zoe's average running speed is about 6 4/5 miles per hour, this is expressed as:
In order to determine the distance he can run in 1 3/4 hour, we can write;
Cross multiply to have:
x * 1 = 7/4 * 34/5
x = 238/20
X = 11.9miles
Hence Zoe will have to run 11.9 miles
