Novay_Z [31]

Options:

Who is right, and why?

a. Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.

b. Kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.

c. Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Answer:

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Step-by-step explanation:

Given

Goal = 3585

Collected = 21\%

Kurt= 10\% * 3600 * 2

Maria = \frac{1}{5} * 3600

Required [Missing from the question]

Who is correct and why?

First, we calculate the actual amount collected.

Actual = Collected * Goal

Actual = 21\% * 3585

Actual = 752.85

Actual = 753 --- approximate

Next, determine the estimate (round 3585 to 3600 and 21% to 20%)

Estimate = 20\% * 3600

Estimate = 720

Next, calculate Kurt and Maria's estimates

Kurt= 10\% * 3600 * 2

Kurt = 720

Maria = \frac{1}{5} * 3600

Maria = 720

<em>Hence, Kurt and Maria are correct because of option (d)</em>

When two computers are working together, they can finish updating software in 9 minutes. How long would they take individually t
tensa zangetsu [6.8K]
First computer takes x min. For 1 min it does 1/x part of work.

Second computer takes (x+24) min. For one min it does 1/(x+24) part of work.

Both computers for one min do   (1/x+1/(x+24)) part of work.

At the same time, both computers for one min do 1/9 part of work.

\frac{1}{x} + \frac{1}{x+24} = \frac{1}{9} &#10;\\ \\  \frac{x+24+x}{x(x+24)} =  \frac{1}{9} &#10;\\ \\9(2x+24)=x^{2} +24x&#10;\\ \\ 18x+216=x^{2} +24x&#10;\\ \\ x^{2}+6x-216=0&#10;\\ \\ D=b^{2}-4ac=36+4*216 = 900&#10;\\ \\ x= \frac{-b+/- \sqrt{D} }{2a}  =  \frac{-6+/-30}{2} &#10;\\ \\ x_{1}=-18, x_{2}=12&#10;&#10;We can use only positive number here. So, &#10;&#10;for the first computer x=12 min,&#10;&#10; for second computer x+24=12+24= 36 min&#10;&#10;Answer 12 min and 36 min.
