Question 1

$DC=AC-AD=20-16=4$

Question 2

By the geometric mean theorem,

$BD^2 = (4)(16)=64 \\ \\ BD=8$

Question 3

By the Pythagorean theorem,

$AB^2 = 8^2 + 16^2 \\ \\ AB^2 = 320 \\ \\ AB=8\sqrt{5}$

Question 4

By the Pythagorean theorem,

$BC^2 = 8^2 +4^2 \\ \\ BC^2 = 80 \\ \\ BC=4\sqrt{5}$

If you start with a board that is 2 3/8" wide and you trim off (cut off) 1 1/4", how wide will your board be?

algol [13]

Answer:

1 1/8"

Step-by-step explanation:

First, make a common denominator.

1 1/4 = 5/4 * 2/2 = 10/8 = 1 2/8

2 3/8 and 1 2/8

Then, subtract.

2 - 1 = 1

3/8 - 2/8 = 1/8

1 1/8"
