The triangle area is 7*2/2 = 7.
The volume is the triangle area times the side length, so 7*18 = 126 cm3
Answer A!
Answer:
m = 6
Step-by-step explanation:
Given
5m + 30 = 60 ( subtract 30 from both sides )
5m = 30 ( divide both sides by 5 )
m = 6

Answer:
8.5 inches
Step-by-step explanation:
First let's find the time t when the depth of the snow is 7 inches.
To do this, we just need to use the value of D = 7 then find the value of t:
![7 = 1.5t + 4](https://tex.z-dn.net/?f=7%20%3D%201.5t%20%2B%204)
![1.5t = 3](https://tex.z-dn.net/?f=1.5t%20%3D%203)
![t = 2\ hours](https://tex.z-dn.net/?f=t%20%3D%202%5C%20hours)
We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:
![D = 1.5*3 + 4](https://tex.z-dn.net/?f=D%20%3D%201.5%2A3%20%2B%204)
![D = 4.5 + 4 = 8.5\ inches](https://tex.z-dn.net/?f=D%20%3D%204.5%20%2B%204%20%3D%208.5%5C%20inches)
The depth of snow one hour from now will be 8.5 inches.
