Alenkasestr [34]2 years ago

Answer:

We will be using the Pythagorean theorem for the first 2 and SOH CAH TOA for the other 3.

a^2 + b^2 = c^2

sin(t) = b/c;  cos(t) = a/c;  tan(t) = b/a

#4)  a^2 + 9^2 = (3sqrt(10))^2                    #5  9^2 + 27^2 = c^2

       a^2 + 81 = 90                                             81 + 729 = c^2

       a^2 = 9                                                       810 = c^2

       a = 3                                                          9sqrt(10) = c

#6    27 + 3 = 30                                        #9  cos(90) = 8/c

                                                                         8/-0.45 = c

                                                                         | 17 | = c  [not the exact value]

#7  8^2 + b^2 = 17^2                                 #8  2^2 + 15^2 = c^2

      64 + b^2 = 289                                          4 + 225 = c^2

      b^2 = 225                                                  229 = c^2

      b = 15  [not the exact value]                     15.3 = c  [not the exact value]

Sorry if something doesn't make sense and felt kind of rushed. Feel free to comment down below my answer if you have any questions and I'll try to clarify it the best I can.

A pro baseball team is having a promotion in which every 10th fan that enters the stadium gets a free hat and every 12th person
mixas84 [53]
Multiples of 10 = 10, 20, 30, 40, 50, 60
This means the 10th, 20th, 30th, 40th, 50th, 60th, ... fan will get a free hat.
Multiples of 12 = 12, 24, 36, 48, 60
This means the 12th, 24th, 36th, 48th, 60th, ... fan will get a free shirt.
So the 60th fan will receive both a hat and a shirt.
Meaning 60 fans will come to the stadium before a fan receives both a hat and a shirt.

What is the equation of the line?
djverab [1.8K]

Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!
