Joe wants to paint a diagonal line across a sign over the door of his office. The sign measures 8 ft. by 6 ft. How long will the diagonal line be?

10 ft.

Step-by-step explanation:

By using the pytahgorean theorem a² + b² = c² we can determine the answer of 10 ft. If you do not know already the length and width are the a and the b so a=6 and b=8. by squaring both of these we get a=36 and b=64 (squaring is just the number times itself so 3² would be 3x3) by adding both of these squared values we get 64+36=100 which means that c²=100 so to get our final answer we just take the square root of c² which is the opposite of squaring it. So √100=10 and that is our final answer

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
