Answer:
Step-by-step explanation:
Equation
-5(-3x+1)=-45 If this is not correct, leave a comment please.
Solution
-5(-3x+1)=-45 Divide by -5
-5(-3x + 1)/5 = -45/-5
(-3x + 1) = 9 Remove the brackets
-3x + 1 = 9 Subtract 1 from both sides
-3x + 1 - 1 = 9 - 1 Simplify
-3x = 8 Divide by -3
-3x/-3 = 8/-3
x = -8/3
or
x = -2.66
or
x = - 2 2/3
Hello from MrBillDoesMath!
Answer:
2035.8 (approximately)
Discussion:
The volume of a cone or radius r and height h is given by the formula:
Volume = (1/3) Pi * r^2 * h. In our case this is:
V = (1/3) Pi * (18)^2 * 6
=(1/3) Pi * 324 * 6 => 324/3 = 108
= 108 * 6 Pi => 108 *6 = 648
= 648 * Pi => approximating Pi by 3.14
= 648 * 3.14
= 2035.8 (approximately)
Thank you,

44,596,251 rounded to the nearest million is 45,000,000. 28,257,934 rounded to the nearest million is 28,000,000.
45,000,000 - 28,000,000 = 17,000,000
17,000,000 is the answer.
