For every 3 tickets you sell your friend sells 4. You sell a total of 12 tickets. How many does your friend sell? Complete problem

Your friend sells tickets

16

Step-by-step explanation:

If 3 x 4 = 12 then you need to do the same to the number 4 so 4 x 4 =16

3 : 4 :: 12 : x proportion 3x = 48 product means/extremes Can you solve for x and answer?

(If not look below.)

Step-by-step explanation:

ratio: 3:4

so divide 12 by 3=4

and multiply 4 by 4=16

your friend sells 16 tickets

ratio is now 12:16

4 : 3 = 12 : x

x = 12 * 4  / 3  = 16

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

idk bring the function back   im not smart
