This is false because $\sqrt{2}$ is an irrational number, despite being between 1 and 2.

bogdanovich [222]

Step-by-step explanation:

Length of third side

$= \sqrt{ {24}^{2} + {16}^{2} } \\ = \sqrt{576 + 256} \\ = \sqrt{832} \\ = 28.84 \\ \approx \: 28.8 \: in$

Length of third side

$= \sqrt{ {24}^{2} - {16}^{2} } \\ = \sqrt{576 - 256} \\ = \sqrt{320} \\ = 17.8885438 \\ \approx \: 17.9 \: in$

Answer: 1st table: P=25h No it's not porportional.

2nd table: h=mi/40 Yes it's porportional.

Step-by-step explanation:

1st table:

P equals your total pages read and your h is equal to the amount of hours you read for. So for every h (hour) there are 25 pages read. So in two hours there are 50 read. Since the table doesn't go 50, 75, 100, that means that there was nat a consistant rate so it's not porportional.

2nd table:

Yes this is porportional. The reason is because to find the time the equasion is h=mi/40. the rate of change between the all of the numbers is equal. so for every 40 miles traveled there is 2 of your time.

Point D is the midpoint of the outer circle that we aim to find the area of

The circle has a diameter of WZ and radii of WC and CZ

We know that YZ=YD=10 cm

Let DC be $x$ and CY be $10-x$

The radius of the outer circle can be written as $8+8+x$ or $10+10-x$ which we can equate to find the value of $x$

$8+8+x=10+10-x$
$16+x=20-x$
$2x=4$
$x=2$

Therefore, the radius of the circle is $8+8+2=18$

And hence the area of the circle is $\pi (18^{2})$ =324 $\pi$
