The angles should add to 540, so
b+ (3/2)b+(b+45)+(2b-90)+90=540
First combine like terms
5.5b+45=540
Then subtract 45 from both sides
5.5b=495
Divide both sides by 5.5
b=90
Final answer: b=90
Answer:
hello :
(2xy)^4 =4x^a (y^b) 4xy
16x^4 y^4 =16x^(a+1) y^(b+1)
a+1 = 4 and b+1 = 4
a=3 and b=3 .......(answer : B)

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.
