Answer:
21
Step-by-step explanation:
- 7 for first 10 shots
- 7 for another 10 shots
- 7 for last 10 shots
Answer:
2x/5 = 6
x 5 x 5
2x = 30
divide by 2 on both sides
x = 15
So you have two of those--when you add those together, you get "seven and eight-tenths," or 7.8 The 2 shorter sides are what's left to still measure. If the total perimeter is 10.4, you get the shorter sides by: 10.4 - 7.8 = 2.6, but REMEMBER, the 2.6 is BOTH shorter sides added together, so each ONE of them is 1.3 SO... your hallway/rectangle is 3.9 meters on each long side, and 1.3 meters on each short side. i hope this helps you
I think the answer to your question is A, hope this helps
3,540 grams of ash
If its density is 2.75 g/cc and
density = mass / volume then its volume is
volume = mass / density
volume = 3,540 g / 2.75 g / cc
volume =

<span>
<span>
1287.272727 cc
So, rounded it is 1,287.3 cubic centimeters but to keep the same number of significant figures, the volume is
