The answer is "A" because whenever you round (up or down) you are only changing the value a teeny bit, which only matters if you want to measure an exact amount of something. Using a calculator gives you the <em>exact </em>answer. <em />Guess and check really doesn't work because there are ∞ numbers. Any answer is not fine because if the answer is 5 and you answer with 9633, that answer is obviously wrong. So, A is right.

Find the circumference of the circle. Round to the nearest tenth.
Natasha_Volkova [10]

Formula for the circumference of a circle: C = pi x diameter

We are given the radius here, but we need the diameter. The diameter of a circle is equal to two times the radius.

diameter = 40 x 2 = 80 in

C = pi x 80

C = 80pi = 251.3 in

Hope this helps!! :)

after two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represen
galina1969 [7]

Answer: y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

________________________

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600
