Answer:
Deceleration =
units/sec^2
Step-by-step explanation:
Given that a car is traveling at when the driver sees an accident m ahead and slams on the brakes.
i.e. if he is coming with speed v units/sec say, he has to make his velocity 0.
Distance travelled = m units
Initial velocity = v
Final velocity =0
Use the third formula as

So he has to apply an acceleration of
units/sec^2 to stop the car in time to avoid a pile up.
Deceleration =
units/sec^2
Answer:
The answer is n = 17
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
Hoped this helped!
brainly, please?
Let's set up two equations:
x+y=20 We know she brought total of 20, some of each so x=small y=big
20x+ 30y=450
x+y= 20
-y -y
------------
x= 20 -y
substitute into the other equation:
20 (20-y) + 30y = 450
400 - 20y + 30y = 450
400+ 10 y = 450
10 y = 50
y= 5
So she brought 5 big cases. Then substitute the value of y into one of the equations.
5+ x = 20
x= 15
So we bought 15 small cases and 5 big cases.

Given:
A recipe calls for
cup of brown sugar for every
cup of white sugar.
To find:
The number of cups of brown sugar that are required for every cup of white sugar.
Solution:
We know that,
Required brown sugar for
cup of white sugar =
cup
Using this, we get
Required brown sugar for 1 cup of white sugar =
cup
cup
cup
So,
cup of brown sugar is required for every cup of white sugar.
Therefore, the correct option is B.
