Answer: Sarah.
d=rt
Miles = (miles/hour)(hour)

So Timmy is driving 70mph

Sarah:
75 = r (1), r = 75mph
150 = r(2), r = 75mph

2.36 to the nearest whole number. Help please
melisa1 [442]

Answer:

2

Step-by-step explanation:

Since if it's 5 or higher you go up but if it's 4 or lower you stay the same. And since 2.36 doesn't have the .5 it would round to 2

In a collision, a 5 kg mass moving at 2m/s transfers all of its momentum to a 1 kg mass. What is the velocity of the 1kg mass af
statuscvo [17]
Answer:
velocity = 10 m/sec in the same direction as the first body did

Explanation:
The momentum of the body can be calculated as follows:
momentum = mass * velocity

For the first body, we have:
mass = 5 kg
velocity = 2 m/sec
momentum = mass * velocity
momentum = 5 * 2 = 10 kg.m/sec

We know that this momentum is transferred completely to the second body

For the second bode, we have:
momentum = 10 Kg.m/sec
mass = 1 kg
momentum = mass * velocity
10 = 1 * velocity 
velocity = 10/1
velocity = 10 m/sec

Finally, we should get the direction of the motion:
Both the velocity of the first and second bodies have positive values. Therefore, the second body is moving in the same direction as the first body did.

Hope this helps :)

7th term in geometric sequence an=2 5(n-1)
Soloha48 [4]
To find the 7th term, all you have to do is plug it in the equation.

First n would equal 7 because we are looking for the 7th term.

Now, let's plug everything we know into the equation.

a7 = 2+5 * (7-1)

= 2 + 5 * 6

= 2 + 30

= 32

In conclusion, the 7th term would equal 32.
