A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?

The height of the TV is 15 inches.

Step-by-step explanation:

if the TV's diagonal is 17 and the width is 8 inches (crazy size for a TV), then we are looking at solving for the height using Pythagorean's Theorem because this is a right triangle situation.

17^2-8^2=a^2  and  289-64=a^2 .  a^2=225  so a = 15.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
