20 hours. Working out: 1000 miles (1000X100=10 hours) 2000 miles (2000X100=20 hours)
Well,a kilometer is 1000 metres.1 meter is 100 centimeters.So 1000X100=100,000 1000 X100 ________ 0000 00000 +100000 ____________ 100,000 centimeters
None. A 1000x100 sq ft is a measure of area. Four such sides also represent a measure of area. It is not valid to convert from a measure of area to a linear measure such as a foot.
Well there is 1000 metres in a kilometre, and a 100 centimetres in a metre therefore 1000x100 = 100000. If you know the meaning of the prefixes it becomes so easy kilo=1000, centi=100th, milli=1000th, etc.
Well, honey, if you're trying to figure out how many times you can fit 1000 into 100,000, the answer is 100. It's simple math, darling. Just divide 100,000 by 1000 and you'll get your answer. Math doesn't have to be a headache, sugar, just keep it simple and you'll be fine.
Example: If you were asked to sample 100 fellows students in your school about soft drink preferences for the school shop, it would be more accurate if, instead of asking 100 friends, you split the school up into certain strata, such as class groups, ages or gender. So if the whole school contains 1000 students of whom 50 are girls in year group 8, an accurate sample of 100 would contain five girls from group 8 (50/1000x100). This process would be repeated with all year groups until the total required sample of 100 was reached. The people to be surveyed in each stratum should be selected randomly..
