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: it will take them 2.22 hours working together.
Step-by-step explanation:
It takes Destiny y 4 hours to file all the daily paperwork. This means that unit rate of Destiny would be
1/4 per hour.
It takes Susan 5 hours to file the same paperwork. This means that unit rate of Susan would be
1/5 per hour.
If they work together, they would work at their own individual rates. This means that their individual rates are additive.
Let t represent the time it will take them if they worked together. Since their combined rate is additive Therefore,
1/4 + 1/5 = 1/t
9/20 = 1/t
t = 20/9 = 2.22 hours
Answer:
-7/2
Step-by-step explanation:
(a) True
Because the sum of the angles in a triangle is 180°
Obtuse angle = angle greater than 90°.
180° - Obtuse angle = less than 90°
So there cannot be another obtuse angles, therefore both the other angles will be acute.
