You need to decide whether to hire three landscapers or hire just two but buy a faster mower; both options will deliver the same
Westkost [7]

Answer:

I think buying a new mower will be a much more financial sound decision because it can last 3 years, however, if you hire landscapers it will cost significantly much more money than buying a new mower.

Step-by-step explanation:

Reason for this is that:

$18×2000 hours= $36,000 each year

For three years: $36,000×3=$108,000

which is more than $8,000

Hence, buying a new mower would be the better solution.

Use logarithms to solve the equation for t. (Round your answer to two decimal places.)
mezya [45]

9514 1404 393

Answer:

  2.56

Step-by-step explanation:

Multiply by (1+6e^(-.7t))/1000:

  2000/1000 = 1 +6e^(-0.07t)

  1 = 6e^(-0.07t) . . . . . . . . . subtract 1

  e^(0.07t) = 6 . . . . . . . . . . multiply by e^(0.07t)

  0.07t = ln(6) . . . . . . . . . take the natural log

  t = ln(6)/0.07 . . . . . . . divide by the coefficient of t

  t ≈ 2.55966 ≈ 2.56

Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place?
melamori03 [73]
Yes, because when you multiply 440,000 times 10 you would get 4,400,000. The 4 represents where the 1 is at right now! Therefore, the answer is yes.
