The teams ratio of games won to games played was 5 to 6 If. The team played 36 games, how many games did the team fail to win
Scrat [10]

Answer:The team failed to win 6 games.

Step-by-step explanation: 5/6 has to be equal to something over 36. Since you multiplied the denominator by 6 you have to multiply the numerator by 6 and 5*6 equals 30. If out of 36 games they won 30. Then to find how many games they lost all that you have to do is subtract 36 and 30 to get 6.

marissa [1.9K]

Answer:

11 - 7i is your answer.

Step-by-step explanation:

All you do is add corresponding numbers.

5 and 6 are the same so you add them together to get 11

-2i and -5i are the same so you add them together to get -7i

11 - 7i is your answer.

Solve for x. <br> a) x=7.5 b) x=16 c) x=17.5 d) x=27.5
lara [203]
X = 17.5

Note: This is done in the interior triangle as the angle will be equivalent to the other two angles.

Here's how you solve it:

You have to use the law of cosine for the interior triangle; the law of cosine is: c^2 = a^2 +b^2 - 2ab times cos (C)

Substitute each factor so that the equation now appears as so:

h^2 = 8^2 + 10^2 - 2(8)(10) times cos (80)

This will give you: h = 11.67

Now, you have to apply this to the law of sin which is a over sin(A) = b over sin (B) = c over sin (C). (Lowercase letters are the opposite side of uppercase angles.)

This will then give you:

11.67 over sin (80) = 8 over sin (S) = 10 over sin (T)

sin -1 ((8 times sin (80)) over 11.67)  is equal to S

sin -1 ((10 times sin (80)0 over 11.67)) is equal to T

Because you now know the angles of S and T, you need to use the law of sin again.

t over sin (T) = s over sin (S)

t = 10 + x
s = 8 + 18 = 22

Thus, you need to substitute the variables to get this equation: 

10 + x over sin (57.54) = 22 over sin (42.45) 

x = 22 times sin (57.54) over sin (42.45) and next to this is -10

Thus, getting the answer of x = 17.50
