Answer:
Both leave at 4 pm . The next time they will leave at 5:20 pm
Step-by-step explanation:
Taking LCM of 16 and 10
16= 2*2*2*2
10= 2*5
LCM= 2*2*2*2*5= 80
1 hour = 60 mins
80/60= 1 hour 20 minutes
Both leave at 4 pm . The next time they will leave at 5:20 pm
The average force exerted by the block exists at -375 N.
<h3>
How to find the average force exerted by the block?</h3>
Given:
Initial Velocity, u = 50m/s
Displacement, s = 10cm = 0.10m
Mass, m = 0.03Kg
Using the relation,
Substitute the values in the above equation, we get:
We know that, f = ma
Putting the values, we get:
f = (0.03)(-12500)
f = -375 N
The average force exerted by the block exists at -375 N.

Answer:
False. It is an equation.
Step-by-step explanation:
The difference between an expression and an equation is that an expression represents a single value (5x + 7) whereas an equation shows that two things are equal.
Answer:
4 students needed
Step-by-step explanation:
We can divide 5/6 and then round it to the nearest tenth which is 0.8.
This means every 0.8 hours 1 student is completed with their work.
We can then divide 3 hours with the 0.8 hours to get 3.75 students additionally needed to cut the time to 3 hours.
Obviously, we can't have 3/4's of a student so we convert that into 1 student, ending up with 4 students additionally needed to complete the work in 3 hours.
Mathematical work:
5 students/6 hours
= 0.8 hours
0.8 hour/3 hours
=3.75 students
Round 3.75 to 4
4 students additionally needed.
Hope this helped.
