Hmark 1 - Item 205023 Erin received the following scores on her last four spelling tests.
23, 82%, 0.8,
17
20
Which of these is Erin's highest score?

82% is her highest score

Step-by-step explanation:

82 is greater than 23, 80, 17 and 20

The hypotenuse of a right triangle is  25 cm, and the shorter leg is 15 cm. Find the length of the other leg.

The other leg is  20 cm

So the equation for the Pythagorean theorem is

a^2+b^2=c^2

The hypotenuse is always the c. It does matter if 25 is plugged into a or b. So

15^2=225 and c^2=25^2=625

So subtract 225 from both sides. You have a^2(or b^2)=400. Square root on both sides. There, a^2(or b^2), i.e. the other leg, is 20 cm.
