Answer:

  • 3003

Step-by-step explanation:

Teams of 5 from the total of 15 students.

<u>Combination of 5 is:</u>

  • nCr = n!/(n-r)!*r!
  • 15C5 = 15!/10!5! = 15*14*13*12*11/(2*3*4*5) = 3003 teams

Solve for x in the diagram below. 15 points :3
OLEGan [10]

Answer: x = 6

Step-by-step explanation:

We know that the angles combined are complementary, meaning they add up to 90 degrees.

Therefore, we can make this equation:

(x + 54) + 5x = 90

Then, combine like terms.

x + 54 + 5x = 90

6x + 54 = 90

Now, subtract the 54 from that side.

6x = 90 - 54

6x = 36

Next, divide!

\frac{6x}{6} = \frac{36}{6}

x = 6

Maslowich

Step-by-step explanation:

sin \: 45 \degree =  \frac{39}{z}  \\  \\  \therefore \:  \frac{1}{ \sqrt{2} }  =  \frac{39}{z}   \\  \\  \therefore \: z = 39 \sqrt{2}  \\ let \: p \: be \: the \: perpendicular \:  \\  \\\therefore \: tan \: 45 \degree =  \frac{39}{p}  \\  \\ \therefore \:1 = \frac{39}{p}  \\  \\ \therefore \:p = 39 \\  \\ sin \: 60 \degree =  \frac{39}{x}   \\  \\ \therefore \:  \frac{ \sqrt{3} }{2} =  \frac{39}{x}  \\  \\ \therefore \: x =  \frac{78}{ \sqrt{3} }  \\  \\ \therefore \: x =  \frac{78 \sqrt{3} }{ 3 }  \\  \\ \therefore \: x =  26 \sqrt{3} \\\\tan\: 60 \degree =  \frac{39}{y}   \\  \\ \therefore \:  \sqrt{3}  =  \frac{39}{y}  \\  \\ \therefore \: y =  \frac{39}{ \sqrt{3} }  \\  \\ \therefore \: y=  \frac{39 \sqrt{3} }{ 3 }  \\  \\ \therefore \: y =  13 \sqrt{3} \\
