Augustin has 20 different chess boards. If he played 3 games per day, each game played on a different board, how long would it t
Nutka1998 [239]

Answer:

514 days

Step-by-step explanation:

We use the formula (r+n-1)/r(n-1)

There are 1540 combinations. Then, we'll divide them by three because were not just finding the amount of combinations, but the time it'd take to play them all.

We get 513.333(cont.)

thats not really possible, so we're gonna go with 514 instead, rounding up. Normally we'd round down, because the number behind the decimal is below 5, but we really want to make sure we get every combination in there.

Hope this is helpful!

Compute the fare without tip: 1 passenger, 9.5 miles. Round to nearest fifth of a mile when dividing.
vladimir1956 [14]

The fare without tip for the Metro Taxi is of 1 passenger and 9.5 miles is $27.83.

The given parameters:

  • <em>Number of passenger = 1</em>
  • <em>Total distance = 9.5 miles</em>
  • <em>Cost of first 0.2 mile = $0.75</em>
  • <em>Cost of additional mile = $0.55</em>
  • <em>Cost of a passenger = $1.50</em>

The fare without tip for the Metro Taxi is calculated as follows;

  • for the first 0.2 mile = $0.75
  • the remaining distance = 9.5 - 0.2 = 9.3 miles

cost \ of \ distance = \$ 0.75 \ \ + \ \ \frac{\$ 0.55}{0.2 \ mile} \times 9.3 \ miles\\\\cost \ of \ distance =  \$ 26.325

Cost of 1 passenger = $1.50

The total cost is calculated as follows;

total cost = $1.50 + $26.325

total cost = $27.83

Thus, the fare without tip for the Metro Taxi is of 1 passenger and 9.5 miles is $27.83.

The complete question is below:

Compute the fare without tip: 1 passenger, 9.5 miles. Round to nearest fifth of a mile when dividing.

Metro Taxi: first 1/5 mi= $0.75, each additional 1/5 mi= $0.55, each additional passenger= $1.50.

Please help me with this homework
Kipish [7]

Answer:

See screenshot below

Step-by-step explanation:

Yes Bus Column:

  1. We need to find an answer for the "no taxi" section. And we have the total and the "yes taxi" section. So, the "yes taxi" section + the "no taxi" section gives you the total. Another way of saying this is total - "yes taxi"  = "no taxi"
  2. 125 - 30 = 95

No Bus Column:

  1. We need to find the total of the "yes taxi" section and the "no taxi" section. So, if we add those two sections together, we'll get the total
  2. 90 + 185 = 275

Total column:

  1. So, this column is really simple to fill out. All we're doing it adding our answers above to get one answer in each section.
  2. "Yes Taxi" section: 30 + 90 = 120
  3. "No Taxi" section: 280
  4. Total section: 125 + 275 = 400
  5. We could have also done the total section by adding together 120 and 280, but we would get the same answer, anyway.

I hope this helps!
