icang [17]

Answer:

y = $\frac{1}{3} x+1$

Step-by-step explanation:

m = $m = \frac{change in y}{change in x} \\m = \frac{3 - (2)}{6 - (3)}\\m = \frac{1}{3} \\Find the value of b using the equation of a line \\y = mx+b\\y =( \frac{1}{3} )x + b\\2 =( \frac{1}{3} ) * (3) + b\\cancel common factor\\1 + b = 2\\b = 1\\y = \frac{1}{3} x + 1$

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.

3/8 is 4 & 3/5 % of what number? (Round to the nearest hundredth.)

Harman [31]

Answer:

n = 8.15

Step-by-step explanation:

3/8 is 4 & 3/5 % of what number?

Rewrite this as: 3/8 is (4 3/5)% of what number?

Convert 4 3/5% into a decimal: 0.046

Then write out and solve the equation 3/8 = 0.046n, where n is the unknown number.

Dividing both sides by 0.046, we get n = 8.15
