Answer:

7/32

Step-by-step explanation:

1. Subtract the 3/4

1 - 3/4 = 1/4

2. Find what 1/8 of 1/4 is

1/4 × 1/8 = 1/32

3. Subtract it from 1/4

1/4 - 1/32

4. Multiply 1/4 by 4/4 to get a common denominator to subtract

1/4 × 4/4 = 8/32

8/32 - 1/32 = 7/32

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.
