Let t = number of hours
The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t
The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t
You want the lengths to be equal, so the equation is
8 - (7/10)t = 6 - (1/5)t
One is significantly fatter than the other and has more friction
Nell's mom: 30 mL for 2 ounces = 15 mL for 1 ounce
Nell's dad: 65 mL for 5 ounces = 13 mL for 1 ounce
15 > 13
Therefore, Nell's mom's chocolate milk is more chocolately.
Answer:
-12/5
Step-by-step explanation:
-4 * 9 = -36 (numerator)
3 * 5 = 15 (denominator)
Take 3 out of both to simplify.
-36/3 = -12
15/3 = 5
Final Answer:
-12/5
