Answer:

#1

<u>Sum of interior angles is 180:</u>

  • y = 180 - (42 + 31) = 107

<u>The law of sines:</u>

  • x / sin 107 = 11 / sin 42
  • x = 11 sin 107deg / sin 42deg
  • x = 15.72

#2

<u>The law of cosines:</u>

  • cos 76  = (6² + 17² - x² )/2(6)(17)
  • 204*0.24 = 325 - x²
  • x² = 325 - 48.96
  • x² = 276.04
  • x = √276.04
  • x = 16.61

#3

<u>Same as above:</u>

  • 2*9.4*10*cos 20 = (10² + 9.4² - x²)
  • 176.66 = 188.36 - x²
  • x² = 188.36 - 176.66
  • x² = 11.7
  • x = √11.7
  • x = 3.42

#4

<u>Sum of interior angles is 180:</u>

  • y = 180 - (52 + 94) = 34

<u>The law of sines:</u>

  • x / sin 34 = 15 / sin 94
  • x = 15 sin 34  / sin 94
  • x = 8.41

Simplify: square root 27x12 over 300x8
alex41 [277]

Answer:

10

-------------

3x^2

Step-by-step explanation:

First lets simplify what is inside the square root

300x8

---------------

27x12

3 * 100 x^8

------------------

3 *9 x^12

The 3's cancel  and we know a^b/ a^c = a^(b-c)

100/9 x^ (8-12)

100/9 x^-4

sqrt( 100/9 x^-4)

Put the negative exponent in the denominator and make it positive

sqrt( 100 / (9x^4) )

We know that sqrt( a / b) = sqrt(a) / sqrt( b)

sqrt(100)

----------------

sqrt( 9x^4)

10

-------------

3x^2

What fraction is 1 yard 2 feet and 6 inches
MA_775_DIABLO [31]

Answer:

Make sure you convert these numbers into one unit. Convert everything to yard. Just convert the feet and inches in yard since it's the biggest unit, and then add them together. You should get a fraction not a whole number.

Joe hosted a praty 582 people came he charged 15 dollars for balcony seats and 10 dollars for ground seats how many people bout
hoa [83]

Answer:

Ground seats = 450 people

Balcony seats= 132 people

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

The money raised (6480) must be equal to the product of the charge per balcony seats (15) and the number of balcony seats sold (b) ;plus the product of the charge per ground seats (10) and the number of ground seats sold (g)

15 b +10 g =6480

The total number of people (582) must be equal to the sum of balcony seats sold (b) and ground seats sold (g).

b+g = 582

Multiplying the second equation by 10, and subtracting it to the first equation:

15 b +10 g =6480

-

10b+10g = 5820

__________

5b =660

Solving for b

b = 660/5 = 132

Substituting b=132 in the second equation:

132+g = 582

g= 582-132

g= 450
