There are only 2 perfect cubes in between 1000 and 2000.
11^3 = 1331
12^3 = 1728
Lots of red herrings in this question! The beacon is circular, so you need to find the area of a circle with a diameter of 36 inches.
Area of a circle = pi x radius^2
remember radius is half the diameter!
Hello from MrBillDoesMath!
Answer:
3
Discussion:
Let the number be "n",
2n + 15 = 21 => subtract 15 from both sides
2n = 21 - 15 = 6 => divide both sides by 2
n = 6/2 = 3
Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15) which gives 21/
Thank you,

Answer:
x=720/41
Step-by-step explanation:
x-143=1-7.2x
left part +7.2x = right part + 7.2x
8.2x-143=1
left part + 143 = right part +143
8.2x=144
x=720/41
