Answers

since there are 90 seconds in a minute and a half you multiply 90 by 2 getting 270 then you subtract 270 from 2000 and you get 1730 meters which is your answer hope this helps!

Answers

Siras ! Don't try to picture this all in your head !
You'll wear out your brain.
You MUST sketch it on a piece of paper.
Draw an x-axis and a y-axis, then draw the two circles.

I'm drawing myself a picture right now, and I'm
supposed to be some kind of a genius.

a). In order to move Circle-Q so that both centers are
at the same point, you need to move the center of Q
4 units down and 2 units to the right.
      When you do that, you'll have the little circle inside the
big circle, with their centers both at the same place.

b). The radius of Q is 2.
   The radius of P is 20.
   What do you have to multiply 2 by, in order to get 20 ?
   THAT's the scale factor to dilate Q so that it has the same
radius as P.
   When you do that, suddenly it'll look like you only have one circle
on the paper ... they'll both have the same radius and their centers are
at the same place, so you can't tell them apart.

c). All circles are similar !

I went online (you could easily go there too). I searched the question
"Are circles similar ?" and a lot of interesting stuff came up. (you could
do that too). I saw a lot of ways to prove that all circles are similar.
The best one says:

   Two figures are "similar" if you can make one of them
   exactly fit on top of the other one (make them congruent)
   with translations and dilations.

You just did that with P and Q !

-- Translation is moving them around.
   You moved Q and put the centers of both circles at the same place.

-- Dilation is blowing it up or blowing it down, so its size changes
but its shape doesn't change.
   You blew Q up so that it had the same radius as P.
   Then the two circles exactly fit over/under each other.

So the two circles are similar.

Final answer:

The listed conversions between standard and scientific notation are mostly correct, with corrections provided for the representations of 900,000 and 100. Scientific notation involves expressing numbers as a decimal between 1 and 10 multiplied by a power of 10.

Explanation:

The conversions between standard notation and scientific notation provided here mostly appear to be correct, however, there are a few errors:

9) 900,000 in scientific notation would be 9 x 105, not 9 x 10-5.

7) 100 in scientific notation would be 1 x 102, not 1 x 103.

Standard notation is a straightforward representation of numbers. Scientific notation, on the other hand, is a method of writing or displaying numbers in terms of a decimal number between 1 and 10, multiplied by a power of 10.

Casey is reading a book for a book report. At 3:30 P.M., he started reading where he had left off the day before. At 5:30 P.M. he was on page 160. At 8:00 P.M. he was on page 280. If reading the book is modeled by a linear function, what page did Casey start on at 3:30 P.M.?

A) 60
B) 64
C) 70
D) 74

Answers

Well, he can read 120 pages in 2.5 hours. So he can read 100 pages in 2hrs, the difference between 5:30 and 3:30 is two hours. So the answer is 60.

160-100=60. Hope this helped!
