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.

During a baseball season, team a scores 9 runs for every 7 runs that team b scores. The total number of runs scored by both team
mrs_skeptik [129]

Answer:

∴ Team b scores is 630

And team a scores is 810

Step-by-step explanation:

Given;

Team a scores 9 runs for every  7 runs that team b scores.

Lets,

Think b is scores  x runs;

Then a is scores x+(2\times\frac{x}{7} );

Because every 7 runs of b , a is scores more 2 runs.

Total number of runs scored by both teams is 1440

Runs score by team a + Runs score by team b=1440

x+(2\times\frac{x}{7} )+  x =1440

2\times x+ \frac{2\times x}{7}=1440

\frac{(14\times x)+(2\times x)}{7} =1440

\frac{16\times x}{7} =1440

16\times x=1440\times 7

x=\frac{10080}{16}

x=630

∴ Team b scores is 630

And team a scores is 630+(2\times \frac{630}{7} )=810
