Answer:

1.25 cm

Step-by-step explanation:

Draw a radius line from the center to one of the top corners.  This forms a right triangle where the hypotenuse is r, the width is 1, and the height is 2−r.  Using Pythagorean theorem:

(2−r)² + 1² = r²

4 − 4r + r² + 1 = r²

5 − 4r = 0

r = 5/4

r = 1.25

Answer:

Step-by-step explanation:

Remark

The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?

It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).

The ratios are still true, but the angles do not match. So the whole answer is incorrect.

Please help me...I don't get it-
DaniilM [7]

Answer:

1. It would be the second block. Bill reads 3 books EACH week. I know you’re looking for that X to be 1 but if you look 3 books x 5 weeks = 15 books and so on.

2. It would be the first block. Exactly on 6 weeks he reads 6 books meaning that by week 3 (which is half) he would have read haof the books (2). And same for week 12 you and another 4 which gets you 8 books.

3. It’s the last block. On week 12 he read 4 books. Half of 12 is 6 so it would be half books and week 3 is half of that which is 1 book per 3 weeks.

4. Is the third block. (Process of elimination lol) but also easily you can find the rate of each week by dividing the 15 books by 10 weeks which gets you 1.5 books read per week
