To write an equivalent expression for the following all that you would need to do is to add the values of 4 and 3 together
As these numbers come before the expression, and then distribute the final answer into the brackets.
Here it would be 35 + 7x.
This is the final answer.
Both of these are equal to each other one being simplified and the other being complex.
The answer to number 1 is B
Answer:
90 customers
Step-by-step explanation:
Total shift time = 2 hours
1 hours = 60 minutes
Total shift time minutes = 2*60 minutes = 120 minutes
Average Time taken to serve 1 customer = 1 minute 20 seconds
lets convert 1 minute 20 seconds in fraction
60 seconds = 1 minute
20 seconds = 20/60 minutes = 1/3 minutes
Thus,
Average Time taken to serve 1 customer = 1 minute + 1/3 minutes = 4/3 minutes
Lets assume she served x customer in her 2 hour shift
total time taken to serve x customer =x*Average Time taken to serve 1 customer = 4x/3 minutes
Given that she the customers for her shift time which is 120 minutes
4x/3 minutes = 120 minutes
x = 120*3/4 = 90
Thus,
Kimiko served 90 customers and this is the number of customer which came through the drive thru during those 2 hours.
I think its B. correct me if wrong
The cosecant is the reciprocal of the sine function. That means you invert all the fractions and you divide 1 by the non-fractions.
csc(0°) = 1/0
csc(30°) = 2/1 = 2
csc(45°) = (√2)/1 = √2
csc(60°) = 2/√3
csc(90°) = 1/1 = 1
