There is a drought and the oak tree population is decreasing at the rate of 2% per year. if the population continues to decrease at the same rate, how long will it take for the population to be a third of what it is? if necessary, round your answer to the nearest tenth.
the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.
you said it was in the question
the correct option is 2.
according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.
it is given that triangles abd, cad, and cba are similar.
two triangles are similar if their corresponding sides are proportional.
in triangle cba, using pythagoras theorem
triangle abd and cba are similar,
triangle cad and cba are similar,
using (1), (2) and (3), we get
therefore option 2 is correct.
