Answer:
They will change color at the same time in the next 180 seconds or 3 minutes
Step-by-step explanation:
Here, we have two spotlights which change colors at intervals.
While one changes every 60 seconds, the other changes every 90 seconds. Now, we are concerned with knowing when they will both change colors at the same time or instant.
The key to solving this is straightforward. What we need to do is to find the lowest common multiple of both numbers i.e 60 and 90.
The lowest common multiple of both is 180 seconds. This means in the next three minutes, both spotlights will change color at the same time.
Let’s take this by counting;
Spotlight A; 60 , 120 , 180
Spotlight B: 90 , 180
Answer: -3/4 and 4/3

Answer:
Step-by-step explanation:
If AD is an altitude, then by definition it drops from the vertex angle (the top angle) and meets the base at a right angle, which measures 90 degrees. That means that 17x + 73 is a right angle:
17x + 73 = 90 and
17x = 17 so
x = 1
