Well the first thing you need to do is set up a proportion.
8 girls 56 girls
-------- = -----------
7 boys x
Now what we have to do is find out what we multiplied by 8 to get 56.
Simply divide.
56 ÷ 8 = 7
So, we figured out that the magic number is 7!
So we multiply the boy number by 7
7 x 7 = 49
So this means that there are 49 boys on the field trip.
Answer:
Use photo math, it will explain it all in different forms
Answer:
490
Step-by-step explanation:
546-56= 490
490+56= 546
Answer:
1.25 g
Step-by-step explanation:
you start with 20g at 0 seconds.
divide by half after 2 seconds and you have 10g.
at 4 seconds you have 5g.
at 6 seconds you have 2.5g.
at 8 seconds you have 1.25g.
The statement that best describes the blocks after the spring is released is the total momentum is zero.
<h3 /><h3>Law of conservation of momentum</h3>
From the law of conservation of momentum, the initial momentum of the system, M equals the final momentum of the system M'
M = M'
<h3>
Momentum of blocks</h3>
Now, since both blocks are initially at rest, the initial momentum M = 0.
Since the initial momentum equals the final momentum after the blocks are released,
M = M' = 0
So, the total momentum after the blocks are released is zero.
So, the statement that best describes the blocks after the spring is released is the total momentum is zero.
