The answer is 2/11
hope this helps :)
The first thing to do was to find the area of the space to do that we would need to do:
220*200= 44000
the area is
![44000ft^{2}](https://tex.z-dn.net/?f=44000ft%5E%7B2%7D%20)
next you would do:
44000/.4 to find how many people can fit
this equals
1100011,000 people can attend the concert
Answer:
3-a
Step-by-step explanation:
it involves variables like x, y, z
in this case a
The denominator can't equal 0.
![11(x-7) \not= 0 \\ x-7 \not=0 \\ x \not= 7 \\ \\ \\ \frac{(2x+1)(x-7)}{11(x-7)}=\frac{2x+1}{11} \\ \\ (2x+1)(x-7) \cdot 11= 11(x-7) \cdot (2x+1) \\ 11(2x+1)(x-7)=11(2x+1)(x-7) \\ \\ x \in R \setminus \{7 \}](https://tex.z-dn.net/?f=11%28x-7%29%20%5Cnot%3D%200%20%5C%5C%20x-7%20%5Cnot%3D0%20%5C%5C%20x%20%5Cnot%3D%207%20%5C%5C%20%5C%5C%20%5C%5C%20%5Cfrac%7B%282x%2B1%29%28x-7%29%7D%7B11%28x-7%29%7D%3D%5Cfrac%7B2x%2B1%7D%7B11%7D%20%5C%5C%20%5C%5C%0A%282x%2B1%29%28x-7%29%20%5Ccdot%2011%3D%2011%28x-7%29%20%5Ccdot%20%282x%2B1%29%20%5C%5C%0A11%282x%2B1%29%28x-7%29%3D11%282x%2B1%29%28x-7%29%20%5C%5C%20%5C%5C%0Ax%20%5Cin%20R%20%5Csetminus%20%5C%7B7%20%5C%7D)
The answer is D.
Answer:
<B = 70°
Step-by-step explanation:
First we need to find x, lets plugin these two equations.
2x - 30 = x + 20
Then find like terms
2x = x + 50 =
x = 50
Then we plugin 50 for x
2(50) - 30 =
100 - 30 = 70
<B = 70°
