0.084 times 0.584 how do you work this problem out
mylen [45]
Ok, so you do regular multiplication with it, and when you have your final answer, you count the number of places behind the decimal place there are in the original numbers, and put the decimal point there. the answer is 0.049056

Help me do this and you will get 100 points

(b) To have no winner within the first 6 tosses means that there must be 3 tails and 3 heads tossed. So we count how many ways can that happen. The number of ways to choose 3 heads (or tails, doesn't matter) from 6 tosses is

{6\choose 3}=\frac{6\cdot 5\cdot 4}{3\cdot 2} = 20

so 20 ways winthin the 6 tosses. but the question was "how many ways among the 128 of 7 tosses" so we need to add the 7th toss by multiplying by another 2 possibilities for the outcome of the 7th toss, giving us the answer: among the 128 there are 40 games that are tied and need the 7th toss.

(c) The probability is the number of tied games (after 6 tosses) divided by the total number of possible configurations among 6 tosses:

P(\mbox{"7th toss needed"}) = \frac{20}{64} = \frac{5}{16}

In ΔBCD, the measure of ∠D=90°, BD = 13, DC = 84, and CB = 85. What is the value of the cosine of ∠C to the nearest hundredth?
Morgarella [4.7K]

Answer: 0.99

Step-by-step explanation: sin 90 Divided by 85 = sin x divided by 13

                                                   sin x =13x sin 90 divided by 85

                                                        sin x = 13divided by 85

                                                            sin x = .152941176

                                                arc sine of  .152941176=  8.79741071 degrees

                                        cos 8.79741071 = .988235294

                                                            .99

Step-by-step explanation:

To make a line parallel you just need to change the y intercept. using desmos.com i put in the original equations and the point given and made a new line and finding the new y intercept by guessing and checking different numbers.
