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: D
Step-by-step explanation:
Remember that the Opposite side to an angle is in the same order of length as the Angle. So, . Using Cross multiplication, this answer can be solved:
, 60 x 12 = 720, and 90 x 8 = 720. N = 8.
, 30 x 12 = 360, and 90 x 4 = 360. N = 4
