At 5 seconds, an object's velocity is 9 meters per second. At 8 seconds, the object's velocity is 25 meters per second. Assuming a constant acceleration, what is the acceleration in meters per second per second of the object? (If necessary, round to the nearest hundredth.)

Answers

Answer 1

Answer:
Acceleration = (change in speed) / (time for the change) .

Change in speed = (25 m/s - 9 m/s) = 16 m/s

Time for the change = (8 sec - 5 sec) = 3 seconds

Acceleration = (change in speed) / (time for the change)

= (16 m/s) / (3 sec)

= (5 and 1/3) m/s² .

(rounded to the nearest hundredth ... 5.33 m/s² . )

Mrs.State needs help solving a math problem.Mrs.Krutchik’s planned to give 45 tests to 108 children. 67•/• of the students got F’s. The rest got A’s how many students got A’s in Mrs.Krutchik’s class?

Answers

Hey!

-----------------------------------------------

Steps To Solve:

Find number of kids who got an F.

67% = 0.67

108 x 0.67 = 72.36

Find the number of kids who got an A.

100 - 67 = 33% of student's passed.

33% = 0.33

108 x 0.33 = 35.64

We can round.

72.36 = 72 students got an F.

35.64 = 36 students got an A.

Check.

72 + 36 = 108

So our rounding is pretty accurate!

-----------------------------------------------

Answer:

33% or 36 student's got an A in Mrs. Krutchik's class.
