Answer: 90 visitors per hour
Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as <em>450 visitors/5 hours = __visitors/1 hour</em>.
To find out what goes in the bank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 450/5 that has a 1 in the denominator.
If we divide the numerator and denominator of 450/5 by 5,
we get the equivalent fraction 90/1 or <em>90 visitors/1 hour</em>.
So now we have <em>90 visitors/1 hour = __visitors/1 hour</em>.
So a 90 must go in the blank.
This means that the museum sees 90 visitors per hour.

Answer:
Sophie factored completely.
Carlos did not factor out a 2 out of his last term
Step-by-step explanation:
-4x² − 10x + 6
Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).
If you look at the last term in Carlos
(x + 3)( -4x + 2)
You can factor out a -2
(x+3) (-2)(2x-1)
It is not factored completely with the negative two inside the parentheses
He could also have factored out a 2
(x+3) (2)(-2x+1)
I like having a positive x so I use the -2
Either would be acceptable.

Step-by-step explanation:
In the quadratic
the sign on the leading coefficient is positive, so the parabola opens upwards. The y-intercept exists where the x's are equal to 0, so the y-intercept is (0, -8). Match that to the table that has those characteristics in it.
