2x
Step-by-step explanation:
Answer:
4/5 of an hour
Step-by-step explanation:
3/10 of an hour (60 minutes) equals 18 minutes
3/4 of 5 km equals 3.75 km
therefore, you can create a ratio of minutes over km equals min over km
let 't' = time
18/3.75 = t/10
cross-multiply to get this equation:
3.75t = 180
divide each side by 3.75 to get:
t = 48 minutes
48 minutes out of 60 minutes equals 4/5 of one hour
Answer:
2x
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
If V = 4πx³ and h = x, then:
4πx³ = πr²x
4x² = r²
r = 2x
The answer is 3:9 because it says that he sold 3 out of the 12 paintings and so it asks first of how many did he sell and he sold three and how many did he not sell and so it's nine left
6w-y=2z
6w=y+2z
w=(y+2z)/6
Hope this helps!
