The triangles are the same. Congruent is when all three sides are equal to each other on both triangles
Answer:
x=-1/2
Step-by-step explanation:
-3(x-4)= -9(x-1)
-3x+12= -9x+9
-3x+9x= 9-12
6x= -3
x=-3/6
x= -1/2
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.
You can approximate the square root of 30 by taking the square root of a number close to it. This is called local linearization. You can take the square root of 36, which is 6, and the square root of 25, which is 5, and state that the square root of 30 is approximately somewhere between 5 and 6
