The mean or average speed of a mobile moving north is: <u>Vprom= 20.575 m/sec</u>
The average speed of a series of given speed values is calculated by <u>summing</u> each of the <u>speeds</u> and then <u>dividing</u> by the number of speeds , as follows:
Speeds:
V1=18.5m/s
V2=22m/s
V3=20.3m/s
V4=21.5m/s
V avg =?
Average V = ( V1+V2+V3 +V4)/4
Vavg = (18.5m/s + 22m/s +20.3m/s + 21.5m/s)/4
Vavg = 20.575nm/sec

Answer:
C
Step-by-step explanation:
57 is a composite number
The calculation of the value of w depends on what is the shape of the given dimension above. The given area of the shape is represented by a which is equal to 184 cm^2. From the formula of the area of the shape you can manipulate and obtain the value of w.
Answer:
26
Step-by-step explanation:
3x2=6
6+15x/x+5 x cancels itself out
6+15+5=26
3-6+12=9
Steps
you have to add first so you must add -6+12 which will be -6
Then you will take 3 - - 6 which will make it 9
