Answer:
20% of number 1 to 70 has one or nine in it
Explanation:
20% numbers from 1 to 70 have 1 or 9 in the unit's digit. 1,9,11,19,21,29,31,39,41,49,51,59,61,69 this is that series of numbers .These are total 14 numbers out of 70 so 14/70×100 gives us 20 % occurrence of 1 or 9 at unit place.
Explanation:
In Lima, the capital of Peru, the climate is very peculiar: it is subtropical desert, with a warm season from December to April and a cool, humid and cloudy season from June to October, with May and November as transitional months.
Wilson's farm would be more likely to have coarse soil than Byron's farm.
Explanation:
The mountain of Arizona and the flat plains of Kansas offer very different conditions when it comes to farming. Both places have their challenges, but Arizona's mountains are much more problematic when it comes to farming. Some of the reasons for this are the:
- arid and semi-arid climate
- lower quality of the soil
- sloping terrain
- large scale erosion
As mentioned, the soil is not of very high quality, and the chances are that its texture will be coarse one. This would make a problem for Wilson, as this type of soil apart from not being very fertile, is also much harder to work on. The other factors contribute to large scale erosion, which makes it very hard to create a fertile top layer, as it will constantly be stripped off by the natural factors.
