Item 6 Your city is represented in a coordinate plane where each unit represents 1 kilometer. The library is at (−3, −3), the po

Snezhnost [94]

We know, shortest distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is :

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So, distance between house and library is :

$d_1=\sqrt{(-5-(-3))^2+(2-(-3))^2}\\\\d_1=5.39\ km$

Distance between library and post office :

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\D=\sqrt{(-3-2)^2+(-3-2)^2}\\\\D=7.07\ km$

Distance between post office and house :

$D=\sqrt{(2-(-5)^2)+(2-2)^2}\\\\D=7\ km$

Therefore, minimum distance that you can ride your bike is (5.39+7.07+7) km = 19.46 km.

Hence, this is the required solution.

It is estimated that light takes 110,000 years to travel the full distance across our galaxy

stepladder [879]

$\bf \stackrel{light~speed}{3.0\times 10^8}ms^{-1}\implies \stackrel{light~speed}{3.0\times 10^8}~\frac{m}{s}\implies 300,000,000~\frac{m}{s}\\\\
-------------------------------\\\\
\textit{how many seconds in a minute?}\qquad 60
\\\\\\
\textit{how many seconds in }\stackrel{1~hr}{60~minutes?}\qquad 60\cdot 60
\\\\\\
\textit{how many seconds in }\stackrel{1~day}{24~hrs}?\qquad 60\cdot 60\cdot 24
\\\\\\
\textit{how many seconds in }\stackrel{1~year}{365~days}?\qquad 60\cdot 60\cdot 24\cdot 365$

now, it takes 1 second for light to travel 300,000,000 meters.

if we know it takes light 1 second to go 300 million meters, then in 365 days or a year, or 60*60*24*365 seconds, it will then travels

300,000,000 * 60 * 60 * 24 * 365 meters in 1 year,

how about in 110,000 years, how many meters has it travelled?

300,000,000 * 60 * 60 * 24 * 365 * 110,000 that many meters.

we know she travels the Milky Way in 110,000 years or 60 * 60 * 24 * 365 * 110,000 seconds

and we know that 110,000 years is 3468960000000 seconds, so

if it travels 300000000 meters in only 1 second, in 3468960000000 seconds, it will travel then (300000000) * (3468960000000) meters

or 1040688000000000000000 meters.

3/5 of 400=x people used it
so we x=400x3/5
x=240
so 240 people used it again.
