need help in reading and writing in math
After the first cut and pile the total thickness will be 0.02mm. On the second cut we double this to 0.04mm; then 0.08, 0.16, 0.32, 0.64, 1.28, 2.56, 5.12, 10.24. So the final thickness is 10.24mm=1.024cm.
Day 1, 50 people, Day 2, 78, Day 3, 106; the increase is 28 per day. We have to get from 50 to 200 people, so that's an increase of 150 from Day 1. 150/28=5 and then some. So after 6 days we have 6*28=168 extra people, making 168+50=218.
One way of working this out is to pick a triangle of a particular shape and size and write down how many of that size there are; then pick a different sized triangle and do the same for that. The answer is likely to be a multiple of 5. I can see more than 20 triangles. How many can you see?
0.4*0.4*0.4*0.4=0.0256. So the height after 4 bounces is 0.0256*2.3=0.05888m=5.888cm. Two more bounces takes us to just under 1cm.
Add all the areas together. Take the area of each lake and divide by the total then multiply by 100 to get the percentage.
Time how fast you breathe in normally. Let's suppose this is 4 seconds. Remember that you breathe slower when asleep. If you're very energetic you may breathe faster on average. There are 60*60*24=86,400 seconds in a day, so that's 21,600 breaths a day. Multiply by 365.25 to find how many breaths in a year=7,889,400 breaths a year. Now multiply by your age. You can round the figures of course. It's only a fun exercise.
a) 1/10 b) 7/10 c) 5/10 d) 7/10 The probability is simply the ratio of the marbles you are counting to the total number of marbles, 10.
You may have to write in your words what the answers are. I hope this helps. Read More: ...
