Answer:

The answer is : y =\sqrt{190}

so, type 190 in the box

Step-by-step explanation:

Notice that there are three right angle triangles in the image given. In order to create equations associated with the Pythagorean Theorem for the three triangles, we add the letters x and z to identify two sides that are missing information. Please see attached image for reference.

In the small right angle triangle on the right, the Pythagorean theorem tells us:

x^2+10^2=y^2\\so\\x^2=y^2-100

In the larger triangle :

y^2+z^2=19^2\\z^2=361-y^2

In the small triangle on the left:

9^2+x^2=z^2

and in this last equation we can substitute the z-squared and the x-squared by the expressions we got before in the other two equations:

9^2+(y^2-100)=(361-y^2)\\81+y^2-100= 361-y^2\\2\,y^2=361+100-81\\2\,y^2=380\\y^2=190\\

Then to solve for "y" we apply the square root:

y =\sqrt{190}

Find the difference between the longest and shortest bean sprouts <br><br>Please i need ​
aniked [119]

Answer:

7/4 inches

Step-by-step explanation:

Longest bean sprout = 8/8 + 8/8

Longest bean sprout = 1 + 1

Longest bean sprout = 2

Shortest bean sprout = 2/8

Difference = 2 - 2/8

Difference  = (16-2)/8

Difference  = 14/8

Difference = 7/4

Hence the distance is 7/4 inches

How do you solve this?
natali 33 [55]
Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.
