Answer:
-60 m/s²
Step-by-step explanation:
We are not given the velocity of the plane at landing but we are given velocities at two time periods
V₅, the velocity of the plane 5 seconds after landing is 110 m/s
Plugging this into the velocity equation we get
(1)
Similarly
(2)
Subtract (1) from
Therefore 
Given 
this evaluates to
-60 m/s²
The negative value is because the plane is actually decelerating which is a negative number
28/11.2 = 2.5
since they are similar and openly stated as parrallelograms, you know that they have a scale of the longest edge of EFGH to the longest edge of JKLM
Answer:
R=19
Step-by-step explanation:
R + 237 = 256
subtract 237 from both sides
R=19
Answer:
Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.
Step-by-step explanation:
Hope I helped.It's just a reminder of helpful things for means!
Answer:
OK this is easy the answer is r=2.4
Step-by-step explanation:
so what you would do is simply add 3.1 and 1.7to get 4.8
then you would divide 4.8 by 2 and get r=2.4
