Answer:
8 people on your street do not have a car.
Step-by-step explanation:
So we know that 95% of people have a car. There are 160 people on your street and your are trying to find out how many people do not have a car.
If 95% of people have a car, then 100% - 95% of people, or 5% of people, do not have a car. Using this we can find how many of the 160 people on your street do not have a car. To do this, we would multiply the percent of people who do not have a car (5%, or 0.05) by the number of people on your street (160).
5% × 160 = 0.05 × 160 = 8
8 people on your street do not have a car.
I hope this helps. :)
Answer:
+2
Step-by-step explanation:

Answer:
combined velocity of the system = 0.033 m/s.
Step-by-step explanation:
taking the bullet and block as single system since there is no external force involved momentum is conserved .
initial momentum of the bullet = mv
where m is the mass of bullet and v is velocity of bullet.
and initial momentum of block = 0 since its velocity is 0.
therefore initial momentum of the system = mv
= 0.005×40
= 0.2
when the bullet stick of together with the block let the combined velocity of the system be V
therefore applying conservation of momentum
mv = (M+m)V
0.2=(6+0.005)V
therefore V = 0.033 m/s
