<h2>
Answer:</h2>
<u>Every 18 feet.</u>
<h2>
Step-by-step explanation:</h2>
<h3>1. Find the LCM between the numbers.</h3>
LCM stands for "least common multiple", and is the least number that results from multiplicating any of the 3 numbers by another number.
Analyze numbers starting from 9 to find the LCM. The first number than can be divided by 3, 6, and 9 is 18. Hence, 18 is out LCM
<h3>2. Interpret the results.</h3>
18 as a LCM means that every 18 feet there will be lights at the same distance in the circular road.

Answer:
3:36 PM
Step-by-step explanation:
Let fraction (y) of the people that heard the rumor , the differential equation that is satisfied by the by y is,
Solving the differential equation,
The total number of inhabitants of the town = 2000
The number of people that heard the rumor = 160
At 8 AM, let t = 0,
= 0.08
By noon, half of the town as heard the rumor.
Then,
Therefore,
k ≈ 0.06106
Calculating time, t when y(t) = 90%
⇒ y(t) = 0.9
t = 7.59 hours
⇒ 7 hours 36 minutes
From 8 A.M. plus 7 hours 36 minutes = 3:36 PM
At 3:36 PM will 90% of the population have heard the rumor
I believe that it's D. F(x) is a very large negative number.
Answer:
a = -x + 2
Step-by-step explanation:
First, you must distribute to get 2x + 2 and adding in the -3x it equals 2x + 2 - 3x = a
Combine the like terms to get -x + 2 = a
Since there is 2 variables then the answer will stay a = -x + 2 because x or a must be substituted in order to find the other variable
The ratio you are told means that for every 5 pink salons, you have 7 yellow swans. This means that if you have more, you have to multiply both values. For example, if you had 10 pink salons, then you would have 14 yellow swans because 5 × 2 = 10 so therefore 7 × 2 = 14. In this case, 390 ÷ 5 = 78, so you need to multiply 7 by 78, which gives you 546 yellow swans in total. I hope this helps!
