Answer:

He is reasonable to an extent, but he is not. He can saw 8 posts with the given materials.

Step-by-step explanation:

To make 9 posts. He would need 108 inches of material. He can only make 8 posts with the materials he has. With the remainder of the material he could possibly make 6/10ths of a post.

Answer:

  D:  2/4

Step-by-step explanation:

Usually when we talk about a point partitioning a segment, we are interested in the ratio of the first segment to the second:

  BC : CD = 2 : 2 = 1 : 1

Since this is not an answer choice, we need to "reverse engineer" the answer list to see if we can find an answer that corresponds to a reasonable interpretation of the question.

__

None of the segments is 3 units long, so neither of answer choices A or B makes any sense.

While segment BD is 4 units long, there is no segment that is 1 unit long, so answer choice C makes no sense, either.

There are segments that are 2 units long and a segment that is 4 units long, so if we interpret the question to be "what is the ratio of BC to BD?" then answer choice D is appropriate.

If P (x,y) is the point on the unit circle defined by real number 0, then csc0=_.​
dezoksy [38]

Answer:

cscθ = \frac{1}{y}

Step-by-step explanation:

cscθ = \frac{Hypotenuse}{opposite}

For a unit circle, radius = 1

hence, hypotenuse = 1

opposite = y

cscθ = \frac{1}{y}
