9 buses.
Explanation:
We divide the number of basketball fans by the number of fans that can be accommodated by the bus. We get 8.4
Since we cannot cut the bus into 0.4 we add another bus so that everyone will get to go.
Another method is
Multiply 8 buses by 34 fans. We get 272 fans will be able to go to a game.
This means that some fans will be left by the bus but our goal is to have everyone go.
And thus we need the 9th bus to carry the remaining 15 fans

Simplify the rational expression. State any restrictions on the variable n^4-11n^2+30/ n^4-7n^2+10
djyliett [7]
To factor both numerator and denominator in this rational expression we are going to substitute n^{2} with x; so n^{2} =x and n ^{4} =  x^{2}. This way we can rewrite the expression as follows:
\frac{n^{4}-11n^{2} +30 }{n^{2}-7n^{2} +10 } =  \frac{ x^{2} -11x+30}{ x^{2} -7x+10}
Now we have two much easier to factor expressions of the form a x^{2} +bx+c. For the numerator we need to find two numbers whose product is c (30) and its sum b (-11); those numbers are -5 and -6. (-5)(-6)=30 and -5-6=-11.
Similarly, for the denominator those numbers are -2 and -5. (-2)(-5)=10 and -2-5=-7. Now we can factor both numerator and denominator:
\frac{ x^{2} -11x+30}{ x^{2} -7x+10} = \frac{(x-6)(x-5)}{(x-2)(x-5)}
Notice that we have (x-5) in both numerator and denominator, so we can cancel those out:
\frac{x-6}{x-2}
But remember than x= n^{2}, so lets replace that to get back to our original variable:
\frac{n^{2}-6 }{n^{2}-2 }
Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is n^{2} -2 \neq 0
n^{2}  \neq 2
n \neq +or- \sqrt{2}

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=37°, and SQ = 56 feet. Find the length of QR to the nearest tenth of a foot
melisa1 [442]

Answer:

  70.1 ft

Step-by-step explanation:

The cosine relation gives the ratio of the adjacent side to the hypotenuse for an acute angle in a right triangle:

  Cos = Adjacent/Hypotenuse

  cos(37°) = SQ/QR

Rearranging gives ...

  QR = SQ/cos(37°) = (56 ft)/0.798636 = 70.1 ft

The length of QR is about 70.1 ft.
