Answer: a = 1.75
Explanation :
4a + 7
Using transposition method we move 4 and change its sign
a = 7 / 4
7 / 4 = 1.75
Therefore,
a = 1.75
Answer: 540 cups
Step-by-step explanation:
Diameter = 20
Radius = 20/2=10
Volume of a cylinder: pi(r^2)h = 3600pi
Cone = (pi(r^2)h)/3 = (20pi)/3
3600pi/(20pi/3) = 540 cups
Answer:
114.31 nautical miles per day
Step-by-step explanation:
Use formula
![S=v\cdot t,](https://tex.z-dn.net/?f=S%3Dv%5Ccdot%20t%2C)
where S is the distance, t is time and v is rate.
If S=11431 nautical miles and t=100 days, then
![v=\dfrac{11431}{100}=114.31\ \text{nautical miles per day}.](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B11431%7D%7B100%7D%3D114.31%5C%20%5Ctext%7Bnautical%20miles%20per%20day%7D.)
