Aspinner with 10 equal sections, na spinner with 10 equal sections, numbered 1 to 10, is spun. then a coin is flipped. what is the probability that the spinner will land on 3 and the coin will land on heads? 5% 10% 12% 20%umbered 1 to 10, is spun. then a coin is flipped. what is the probability that the spinner will land on 3 and the coin will land on heads? 5% 10% 12% 20%

5%

Step-by-step explanation:

A spinner and a coin flip are both independent events.  This means that the results of the event do not depend on the results of previous events.   Since the spinner has 10 equal sections that are all numbers differently, the probability of a certain outcome is the same each time.  In this case, the total number of outcomes is 10 and the chance that you would land on 3 is '1', so the overall probability is .

Flipping a coin is also independent because the probability of getting heads or tails is the same with every flip.  The chance of landing on heads is 1 out of 2 or .

Since you are combining these events, you take each probability and multiply them together:

Dividing 1/20 and multiplying by 100 gives you a percentage of 5%.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
