By conservation of momentum,
(110.0 kg) (1.5 ms⁻¹) + (170.0 kg) (-2.0 ms⁻¹) = (110.0 kg) (-2.75 ms⁻¹) + (170.0 kg) v
where v is the final velocity of the second car.
Solve for v :
-175 kg•ms⁻¹ = -302.5 kg•ms⁻¹ + (170.0 kg) v
127.5 kg•ms⁻¹ = (170.0 kg) v
v = (127.5 kg•ms⁻¹) / (170.0 kg) = 0.75 ms⁻¹
Proportional is the relationship two numbers share. for instance, 3 : 6. for every three, there is six. for every one, there is two.
a table would be proportional if the top numbers and the bottom numbers corresponds, such as 1 on the top and 2 on the bottom. it would continue like 2 : 4, so on and so forth.
you can tell if fractions are proportional by using cross multiplication.
Answer:
x = 1
Step-by-step explanation:
Firstly, look at the left hand of the equation
1/0.001 = 1000 = 10^3
then
10^3x = 1000= 10^3
then
10^3x = 10^3
then
x= 1
Answer:
$318
Step-by-step explanation:
First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be 
. Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.
The problem tells us that we are driving 96 miles, so we can plug in 96 for 
and solve.
The total cost of the rental is going to $318.
Hope this helps!
