4 students is ______ % of 20 students

Mathematics
1 answer:
Yuliya22 [10]3 years ago
5 0

Answer:

4 students

Step-by-step explanation:

We can say that 20 students represent 100 % and that 4 students represent x % of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 % Answer: 4 students is 20 % of 20 students. Hope this helps. Let me know if you need additional help!

7. A boy on ice skates has a momentum of 200 kg m/s to the left at a velocity of 20
tankabanditka [31]

Answer: 10 m/s

Step-by-step explanation:

Given

Momentum of boy P=200\ kg.m/s

Mass of boy is m=20\ kg

Momentum is the product of mass and velocity

P=mv

Substitute value

\Rightarrow 200=20\times v\\\Rightarrow v=10\ m/s

Thus, the boy is moving with a velocity of 10 m/s
