Answer- 1,530
We find the volume of the path in cubic meters and multiply by 106 bags per cubic meter.
The path is an annulus with inner radius r=7 m and outer radius s=7+2=9 m and depth in meters d=50/1000 = 0.05 m.
The volume is the area of the path times its depth; the area is the difference of the area of the outer and inner circles of the annulus.
We need
Answer: 533
Answer:
x=2
Step-by-step explanation:
Expanding, we have 3 - 8-64x=-133.
Combining like terms, we have -5 - 64x=-133
Adding 5 to both sides, we have -64x= -128
Dividing by -64, we have x = 2
Answer:
c
Step-by-step explanation:
The numbers DO differ by 10 if they are
- 1 and 11
- 2 and 12
- 3 and 13
- 4 and 14
- 5 and 15
Each outcome technically has two ways of occurring, but since we're taking two marbles at a time, that would be the same as saying, for instance, that drawing 1 and 11 is the same as drawing 11 and 1. We only count such an event once.
So the answer is (a) 5.
