If you mean the quantity of ways to dress John,
he can choose any one of his 12 pairs of socks to combine with any one of his 3 pairs of shoes and any one of his 5 pairs of pants and any one of his 5 <span>shirts.
12 </span>ways to choose pair of socks and 3 ways to choose pair of shoes and 5 ways to choose pant and also 5 ways to choose a shirt.
12*3*5*5=900.
900 ways to dress him...
Use different conversion factor to accomplish the task given above,
a. (78.9x10^-13 g) x (1 x 10^12 picogram/ 1 gram) = 7.89 pg
b. (6.41x10^-10 L) x (1 x 10^9 nanoliter / 1 L) = 0.641 nL
c. (3.15x10^11 m) x ( 1 x 10^-12 terameter / 1 meter) = Tm
d. (80 x10^-19) x (1 x10^18 atto / 1) = 8 atto
The average speed for the journey from Llanfyllin to Bala is 14 km/h
Average speed is the ratio of total distance travelled to total time taken. Also, average speed can be given as the average of the different speeds.
Let d₁ represent the distance from Llanfyllin to Vyrnwy and t represent the time taken, since the speed is 12 km/h, hence:
12 = d₁/t
d₁ = 12t
Let d₂ represent the distance from Vyrnwy to bala and t represent the time taken. Since they spent the same time, since the speed is 16 km/h, hence:
16 = d₂/t
d₂ = 16t
Average speed = total distance/total time
Average speed = (d₁ + d₂) / (t + t)
Average speed = (12t + 16t) / 2t
Average speed = 28t / 2t
Average speed = 14 km/h
Hence their average speed for the journey from Llanfyllin to Bala is 14 km/h.
