4 times because if you count 10, 20, 30, 40, so it has to be 4
The given expression is:
(x^3 * y^4) / (3y^4)
We can notice that the term y^4 is a common term found in both the numerator and the denominator of the given expression, therefore, we can cancel this term from the both numerator and denominator (as if you divided both numerator and denominator by y^4).
Doing this, we will have the simplified form of the expression as follows:
(x^3) / (3)
To find this out first we will see how many cars they assemble in 1 hour. Lets do it:-
150 / 3 = 50
50 cars per hr
50 * 8 = 400
400 cars in 8 hrs
CHECK OUR WORK;-
400 / 8 = 50
We were RIGHT!!
So, in 8 hrs the factory can assemble 400 cars.
Hope I helped ya!! xD
