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

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 probability of 2/9
Identify the expression that does not belong and explain your reasoning: 5.25 • 10^7 (2.1 • 10^2)(2.5 • 10^5) 52.5 • 10^8 (2.1)(2.5) • 10^2+5
Solution 1
D does not belong  because the first 3 digits of the product of the first 3 equations is 525 and for D it is not.

Mr. Grayson owns a wood company that sells trees, wood materials, and specialty items created from wood. (Score for Question 1: ___ of 4 points) 1. One of Mr. Grayson’s customers, Zenani, is creating an art wall on which she will display some art in triangular frames. She wants three frames, each in the shape of a right triangle. (a) For the first frame, Zenani already has two wooden pieces that are 13 in. and 16 in. long. Zenani says that since she wants the frame to be a right triangle, there’s only one possible measurement for the last piece of wood. Is Zenani right? If so, what is that last measurement? If not, explain why not and give all possible measurements for the last wood piece. Round to the nearest tenth. (b) For the second frame, Zenani asks Mr. Grayson to double the measurements of the first triangular frame to make a new frame in the shape of a right triangle. Will Zenani’s strategy work for the second frame? Explain why or why not. (c) For the third frame, Zenani asks Mr. Grayson to add the same measurement to each of the sides of the original triangle frame to make a new frame in the shape of a right triangle. Will Zenani’s strategy work for the third frame? Explain why or why not. Answer:   ( Score for Question 2: ___ of 4 points) 2.

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.  They could either be both legs, or one could be the hypotenuse:

Hypotenuse: 13² + b² = 16²
                     169 + b² = 256
                     169 + b² - 169 = 256 - 169
                      b² = 87
                      b = √87 = 9.3

Both legs:   13² + 16² = c²
                   169 + 256 = c²
                   425 = c²
                   √425 = c
                   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).  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.  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.  These do not have the same ratios; 3/5 is not the same as 4/6 or 5/11.

Jason is covering an ottoman with fabric. The ottoman is in the shape of a rectangular prism that is 37 cm long, 21 wide, and 30 cm high. How much fabric is needed to cover the sides and top of the ottoman? Explain your strategy.
Solution 1
We know that
we need to calculate the surface area including only one base

surface area=area of the base+perimeter of the base*height

area of the base=37*21----> 777 cm

perimeter of the base=2*[37+21]----> 116 cm

height of the prism=30 cm
surface area=777+116*30-----> 4257 cm²

the answer is
4257 cm²
