Here is the step by step explaination
Tax = 0.35 * Earnings (Earnings < $100,000)
Tax = 0.35 * $100,000 + 0.45 * (Earnings - $100,000) ($100,000 < Earnings < $500,000)
Tax = 0.35 * $100,000 + 0.45 * $400,000 + 0.55 * (Earnings - $500,000)
(Earnings > $500,000)
Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.
Explanation: By applying the circumference into the equation r = 
, we get r = 
which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.
Hope this helps! :D
Answer:
(a) 3
(b) 4
(c) 3
Step-by-step explanation:
To find the number of significant figure, ignore all zeros on the left and count the remaing digits.
(a) ignore 0.0, so 590 is 3 s. f.
(b) no zeros to the left, so 4 s. f.
(c) ignore 0.00, so 122 is 3 s. f.
