Answer:
![272 in^2](https://tex.z-dn.net/?f=272%20in%5E2)
Step-by-step explanation:
The cereal box is a rectangular prism.
Using net of a rectangular prism (cereal box), the surface area
![=2(lw+wh+lh)](https://tex.z-dn.net/?f=%3D2%28lw%2Bwh%2Blh%29)
The dimensions of the cereal box is l=2, w=8, and h=12,
We substitute these values into the formula to get:
![S.A=2(2*8+2*12+8*12)](https://tex.z-dn.net/?f=S.A%3D2%282%2A8%2B2%2A12%2B8%2A12%29)
This simplifies to:
![S.A=2(16+24+96)](https://tex.z-dn.net/?f=S.A%3D2%2816%2B24%2B96%29)
We add within the parenthesis to get:
![S.A=2(136)](https://tex.z-dn.net/?f=S.A%3D2%28136%29)
This finally gives us:
![S.A=272 in^2](https://tex.z-dn.net/?f=S.A%3D272%20in%5E2)
Your y-intercept would be (0,-15) and your x-intercept would be (-60,0)
Answer:
0.5 minutes
Step-by-step explanation:
Since we are provided the equation and the current height of the candle (which would be 25 inches) we can simply replace this current height with the variable h and then solve the rest of the equation to find out the value of m when the height of the candle is at 25 inches.
h = 32−14m
25 = 32−14m ... subtract both sides by 32
-7 = -14m ... divide both sides by -14
0.5 = m
Finally, we can see that after 0.5 minutes the candle would have melted down to 25 inches.
