Answer:
9
Step-by-step explanation:
9
you can always use your fingers or make circcles to count
#9A)15>7-t\3( multiply both sides by 3
45>7-t(collect the like terms
45-7=-t
38>-t
answer=-38<t
#8)-15>_7+2m
-15-7>_2m
-22>_2m (divide both sides by 2
-11>_m
#7)1-4n>_37
-4n>_37-1
-4n>_36(divide both sides by -4
n<_-9
#6)23>_3x-4
23+4>_3x
27>_3x
9>_X
#5)-6>w\-4(multiply both sides by -4)
24>w(choice D is the correct answer
Answer:
Rate = (4C)cars/3(H)hrs
Step-by-step explanation:
The expression of the above formula for C fraction of 4 cars and H fraction of 3 hours will be 4(C)/3(H) since he can tune 4 cars every 3 hours
The hemisphere is half the volume of a sphere. Since we are given the circumference, we can solve for the radius of the sphere. That is
![r=\frac{116}{2\pi }=18.462\:cm](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B116%7D%7B2%5Cpi%20%7D%3D18.462%5C%3Acm)
Part A
We can now compute for the volume of the hemisphere.
![V=\frac{1}{2}\times \frac{4}{3}\pi r^3=\frac{1}{2}\times \frac{4}{3}\pi \left(18.462\right)^3=13179\:cm^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%5Cleft%2818.462%5Cright%29%5E3%3D13179%5C%3Acm%5E3)
Part B
We just need to convert the volume into its corresponding gallons
