Acandle that is 8 inches tall burns at a rate of 3/4 inches per hour. find the height of the candle after 4 hours

we know it burns 3/4 of an inch in 1 hour, how about in 4 hours?

3/4 + 3/4 + 3/4 + 3/4, or simply.......

so in 4 hours it has burned out 3 inches, it was originally 8 inches, 8 - 3 = 5.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
