You are playing a game where you draw a card from a standard deck, and you will win $13 if you draw a face card,
marissa [1.9K]

Answer:

Step-by-step explanation:

win

There are 3 face cards / suit. Every suit contains a Jack, Queen, and king.

There are 4 suits so the number of face cards is 3*4 =  12

There is 1 ace / suit

There are 4 suits so the number of aces is 1 * 4 = 4

The gain from the face cards = 12 * 13 = 156

The gain from the aces = 4 * 3 =               12

Total gain = 168

Losses

Any other card costs you $5

How many cards is that? 52 - 16 = 36

Each one costs 5 dollars

Total loss = 5 * 36 = 180

So each time you play the game, you can expect to lose 180 - 68 = 12 dollars. You should walk away quickly from this one.

How far, D, does a vehicle travel if it is moving at a rate, r, of 60 km/h and it travels for t =150 minutes? Use the formula D=
strojnjashka [21]

The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.

Step-by-step explanation:

            The given is,

                   Moving rate, r = 60 km/h

                   Time, t = 150 minutes

Step:1

            We need to find the distance traveled by the vehicle,

            From given the formula is

                        D = rt

            Where,

                D = Distance in Km

                 r = Moving rate in Km/h

                 t = Time in hours

Step:2

         We need to convert the time minutes to hours

                   t = \frac{150}{60} hours

                   t = 2.5 hours

Step:3

        Distance traveled by the vehicle is,

                D = 60 × 2.5

                    = 150

                D = 150 Km

Result:

      The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.
