8. a candle is 4 inches tall and burns at the rate of 0.6 inch per hour. if the height of the candle after x hours is 1.5 inches, write an equation to represent the situation. then use this equation to find the expected number of hours in which the candle melted to 1.5 inches.

Answer with Step-by-step explanation:

A candle is 4 inches tall and burns at the rate of 0.6 inch per hour.

i.e. after 1 hour height of candle=4-0.6 inches

After 2 hours height of candle=4-0.6-0.6 inches

after x hours height of candle=4-0.6x

Also,

If the height of the candle after x hours is 1.5 inches

⇒  4-0.6x=1.5

⇒ 0.6x=4-1.5

⇒ 0.6x=2.5

⇒ x=2.5/0.6

⇒ x=4.166

Hence, equation to represent the situation. is:

4-0.6x=1.5

and the expected number of hours in which the candle  melted to 1.5 inches is:

4.166 hours

The answer for this triangle is

45 degrees  

That is because you see the small square at the right bottom of the triangle, that square means it's 90 degrees and the other two degrees half to be

45 degrees
