What fraction is represented by the portion of the figure that is NOT shaded? (2 out of 10 are shaded)
OverLord2011 [107]

Well let's see.

If the figure is split up into 10 pieces, then
each piece is  1/10  of the whole figure.

If  2  of the pieces are shaded, then
2/10  of the whole figure is shaded.

How many pieces are left ?

There were 10 pieces all together, and
2 of them are shaded.  Hmmm.  I think
there are probably  (10 - 2) = 8  of them left
that are not shaded.

8 pieces makes  8/10  of the whole figure.

Hans wanted to find the length of the hypotenuse of the triangle. Which statement correctly identifies his error? ​
KonstantinChe [14]

Choice 1. He did not square 40, he just multiplied by 2.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The hypotenuse measures c cm while the other sides are 40 cm and 9 cm each.

Step 2:

According to the Pythagorean theorem,

9^{2} +40^{2} = c^{2}.

81 + 1600 = c^{2} .

1681 = c^{2} .

\sqrt{1681} = c.

This is the correct solution to the given problem. Hans did not square 40, he just multiplied by 2. Which is the first option.

yulyashka [42]

Answer:y= -2/5x-3

Step-by-step explanation:

It's actually pretty simple, all you gotta do is flip the fraction around so if it is 5/2x now is 2/5, and then change the sign, since it was positive now it's negative
