The lines appear to be parallel. We can check this out by examining the
two equations, and we see that sure enough, both lines have the same
slope (1/2) so they're definitely parallel. Parallel lines never intersect,
so this pair of equations has NO solutions. NONE. Zero. Bubkes. Nada.

Anestetic [448]

Answer:

1/1024.

Step-by-step explanation:

There are 3 odd numbers in the numbers from 1 to 6. So:

Probability (one toss is odd) = 3/6 = 1/2.

So the Probability ( 10 tosses are all odd) = (1/2)^10

= 1/1024.

If it takes 10 seconds for 10 printers to print out 10 pages of paper, how many seconds will it take 50 printers to print out 50

Fed [463]

Lets use the formula $RWT=J$ 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:

$R(10)(10)=10\\R(100)=10\\R=\frac{10}{100}\\R=0.1$

<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use $R=0.1$ (previously found) to figure out T.</em>

<em> $RWT=J\\(0.1)(50)T=50\\5T=50\\T=\frac{50}{5}\\T=10$ </em>

So it will take 10 seconds for 50 printers to print 50 pages.
