A. 39,000.
Step-by-step explanation:
Volume of the lower prism = 30^3= 27,000
Volume of the pyramid = 1/3 area of the base * height
= 1/3 * 900 * 40
= 1200
Volume of the whole solid = 27000 + 12000
= 39,000,
Answer:
Step-by-step explanation:
If you are always included to lead, that leaves 10 students to choose from.
If all that is important is being selected, then there are 10C3 = 120 ways to choose them.
If each selection has a unique duty, then there are 10P3 = 720 ways to assign them their jobs.
Step-by-step explanation:
65 km / h = 65,000 m / 3600 s
what do we need to multiply 3600 with to get 3 ?
3600 × f = 3
f = 3/3600 = 1/1200
now, we need to multiply 65,000 by the same factor to get how many meters the car is driving in these 3 seconds :
65000 × 1/1200 = 65000/1200 = 54.16666666...
so, rounded, it travels 54 meters in 3 seconds.
