Given:
Number of students = 35
Two out of every five boys in the club are boys.
To find:
The number of students in the club that are boys.
Solution:
Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.
Let the number of boys be 2x and number of students be 5x.
According to the question,
Now, the number of boys is
Therefore, 14 students in the club are boys.
Answer:
B.4
Step-by-step explanation:
Plug in the numbers. it will be 24=2m(4) since u plug in 24 for j and 3 for n. 24=2m(3). This will be 24=6m. Divide by 6. m=4
Answer:
The answer is (A.)
Step-by-step explanation:
4 x 9 = 36
6 x 9 = 54
8 x 9 = 72

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.
