gregori [183]

Answer:

Step-by-step explanation:

Let c represent the total cost of booking either Uber or Lyft for x miles.

Let m represent the number of miles ridden with either Uber or Lyft.

Uber charges $0.80 per mile and a booking fee of $2.30. This means that the total cost of riding with Uber for m miles would be

c = 2.30 + 0.8m - - - - - - - - - -1

Lyft charges $1.07 per mile with no booking fee. This means that the total cost of riding with Lyft for m miles would be

c = 1.07m - - - - - - - - - -2

Equation 1 and equation 2 are the system of equations that bests models this situation

A company has an opportunity to bid on three contracts. Determine which would be the best investment given the information in th

MariettaO [177]

CONTRACT PROFIT, (P)* OF PROFIT...(P)*. TO BREAK EVEN...LOSS, (P)* OF LOSS

Southeast $45,000, 50% 30% $6,000, 20%

Southwest $60,000, 35% 40% $10,000, 25%

California $112,000, 20% 40% $40,000, 40%

I think that the best contract would be with SOUTHEAST. It probability of having a profit is higher than the other two at 50% while its probability of incurring a loss is lesser than the other two at 20%.

Despite the bigger value of its contract profit of the other two, these value will still be greatly affected by its corresponding probabilities.

(2.5×10−8)(9×10−10)<br><br> Express your answer in scientific notation.

Lunna [17]

Answer: 2.25x $10^{-17}$

Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in $10^{x}$ form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:

2.5 x $10^{-8}$ x 9 x $10^{-10}$ = 22.5 x $10^{-18}$ = 2.25x $10^{-17}$
