Answer:
Step-by-step explanation: If Professor Lam grades 4 papers per hour, in 11 hours he will graded 44 papers. (11 x 4= 44). He had previously graded 6 papers giving him a total of 50 papers graded. His assistant can grade 5 papers per hour, thus it would take him 10 hours to grade the same amount of papers as Professor Lam. (10 x 5= 50) Thus: 11 hours Professor Lam 50 papers graded; 10 hours his assistant 50 papers graded.
Yes because if you put any number as “x” you will always get the same answer.
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
Answer:
1 day ; 10^0
Step-by-step explanation:
Given that:
Order received = 10^6 pages
Number of machines = 100
Daily printing capability by each machine = 10^4
Hence, total output per day = (10^4) * 100 = 10^4 * 10^2 = 10^4+2 = 10^6
Number of days required = number of order / daily output
Number of days = 10^6 / 10^6 = 1
In exponent form:
10^6 / 10^6 = 10^6-6 = 10^0
