Answer:
1.30 p.M.
Step-by-step explanation:
The factory whistle blowed at 1:00 p.M, and it blows every 30 minutes, so it will blow again at 1:30 p.M.
The clock tower chimed at 1.00 p.M., and it chimes every 15 minutes, so it will chime again at 1:15 p.M, and after that, it will chime again at 1:30 p.M.
So, you will hear them both at the same time at 1:30 p.M.
We can also solve this problem using LCM:
the least commom multiple between 15 and 30 is 30, so we just need to sum 30 to the inicial time (1:00 p.M.), so the time they will "find each other" again is 1.30 p.M.
I believe that they are both the first answer because when the sign has a line under it, it is darken in the circle
Answer: C: 12/5
Step-by-step explanation:
y intercept is where x is 0, so set x equal to 0
0+5y=12
y=12/5
M = 6 - 5n hope this helps
Answer:
10 units
Step-by-step explanation:
Area of a triangle is 
= Area
where h is the height, and b is the base
We can substitute these values into the area equation and get:
Multiply both sides by 2:
x * 10 = 100
Divide both sides by 10:
x = 10
The missing side is 10 units long
