A candle that is 10 inches tall burns at a rate of 1/4 inches per hour. Find the height of the candle after 12 hours. *

7 in

Step-by-step explanation:

Step one:

Given data

A candle that is 10 inches tall burns at a rate of 1/4 inches per hour

let the number of hours take to burn completely be x

and the lenght after certain time be y

So

The expression for the situation is

y= 10-1/4x

y= 10-0.25x

for x= 12

y=10-0.25*12

y=10-3

y= 7 in

After 12 hours the length is 7 in

step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
