Question
Find the percent of decrease from 280 to 210. Round to the nearest tenth of a percent, if necessary. a 0.3% b 25% C 33.3% D 133.3%
Solution 1
I got the answer c and if I am correct then it is repeating also
Solution 2
280n = 210
Isolate n:
n = 0.75
1.0 - 0.75
25% decrease, option b
Question
Fruit is being handed out at a picnic. The basket contains 5 bananas, 3 oranges and 2 apples. If two pieces of fruit are handed out one after the other, which combination would have a probability of 2/9
Solution 1
Because there are 9 fruits, it should be n/9, depending on the fruit.
Apples are 2/9, so:
The combination for apples would have a probabilityÂ of 2/9

Solution 1
Question 1:
A) No; 9.3 or 20.6.
B) Yes, because the triangles are similar.
C) No, because the triangles will not necessarily be similar.

There is not enough information to answer Questions 2 or 3.

Explanation for Question 1:
A) We are not told which side is the longest, so these two sides could be placed anywhere in the Pythagorean theorem.Â  They could either be both legs, or one could be the hypotenuse:

Hypotenuse:Â 13Â² + bÂ² = 16Â²
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â 169 + bÂ² = 256
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â 169 + bÂ² - 169 = 256 - 169
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  bÂ² = 87
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  b =Â âˆš87 = 9.3

Both legs:Â Â  13Â² + 16Â² = cÂ²
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â 169 + 256 = cÂ²
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â 425 = cÂ²
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â âˆš425 = c
Â  Â  Â  Â  Â  Â  Â  Â  Â  Â 20.6 = c

B) The two triangles will be similar, since each pair of corresponding sides will have the same ratio (2, since it is doubled).Â  Similar triangles have the same angle measures, so this must also be a right triangle.

C) Simply adding a value to each side will not preserve similarity.Â  For example, if we had a triangle with sides 3, 4, and 5, adding 2 to each side would give us 5, 6 and 11.Â  These do not have the same ratios; 3/5 is not the same as 4/6 or 5/11.
