Let x = the number of hours Eva needs to complete the job
and y = the number of hours Emily needs to complete the job
x = 6
1/x + 1/y = 1/4
(The amount of work Eva does in 1 hr + the amount of work Emily does in 1 hr should equal 1/4 of the total work)
1/6 + 1/y = 1/4
1/y = 1/12
y = 12 hours
Emily would take 12 hours to do it by herself.
Answer: c. 21,000
Step-by-step explanation:
Since, by the given diagram,
The approximate number of security guard job opening = 39,000
And, the approximate number of pharmacy technicians job opening = 18,000
Hence, the difference of the number of security guard job opening and the number of pharmacy technicians job opening = 39,000 - 18,000 = 21,000
Thus, the job openings for security guards is approximately 21000 greater than that of pharmacy technicians.
⇒ Option C is correct.
Answer:
Yes, the table shows a proportional relationship
The value of y when x is 11 is 1331
Step-by-step explanation:
Let us check the relation between x and y in the table
∵ x = 4 and y = 64
∵ 64 = 4³
∴ y = x³
∵ x = 5 and y = 125
∵ 125 = 5³
∴ y = x³
∵ x = 6 and y = 216
∵ 216 = 6³
∴ y = x³
∵ x = 10 and y = 1000
∵ 1000 = 10³
∴ y = x³
∵ All the values on the table give the same relation
∴ x and y are proportion
∴ The table shows a proportional relationship
∵ y = x³
∵ x = 11
∴ y = (11)³
∴ y = 1331
∴ The value of y when x is 11 is 1331
Answer:
$100
Step-by-step explanation:
1st q. 2nd q. 3rd q. 4th q. 5th q
x. 2x. 3(2x)=6x. 4(6x)=24x. 5(24x)=120x
100. 200. 600. 2400. 12000
since the 5th q was worth 12000 we know:
120x = 12000
x = 100
