Lets use the formula to solve this, where,
- R is the rate
- W is the number of workers/things
- T is time
- J is number of jobs/things
<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -
W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:
<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use (previously found) to figure out T.</em>
<em></em>
So it will take 10 seconds for 50 printers to print 50 pages.
ANSWER: 10 seconds
Answer:
<u>Option D. 21</u>
Step-by-step explanation:
The question is as shown in the attached figure 1
The Venn diagram representing the problem is the attached figure 2
D ⇒ Dog , C⇒ Cat and P ⇒ parakeet
Let the The families had parakeet only = X
A survey of 260 families show that:
99 had dog
76 had cat
34 had dog and cat
98 had neither a cat nor a dog nor a parakeet
8 had a cat a dog and a parakeet
So,
The families had a dog and a cat only = 34 - 8 = 26
The families had a dog only = 99 - (26 + 8 ) = 65
The families had a cat only = 76 - (26 + 8) = 42
∴ X = 260 - ( 98 + 8 + 26 + 65 + 42 ) = 260 - 239 = 21
So, The families had a parakeet only = 21
<u>The answer is option D</u>
