Anew candle is 12 inches tall. it burn at a rate of 0.75 inches an hour. how tall will it be after 4.6 hours?

8.55 inches

Step-by-step explanation:

We can use the slope intercept form to write this equation

y = mx+b where m is the lope and b is the y intercept

The y intercept, b, is how tall the candle is when we start, 12 inches

The slope is the rate at which it is burning or -.75  (the negative is because it is burning or getting smaller)

y = -.75x+12

or rewriting

t = 12-.75h  where h is the hours and t is how tall

We are burning for 4.6 hours

t = 12-.75(4.6)

t = 12 -3.45

t= 8.55

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
