Answer:

Step-by-step explanation:

inland city has the coldest winter and warmest summer.

inland city, since it has a higher median of around 14.5 Celsius while coastal city has around 14 degrees Celsius

I would prefer to live in coastal city, since it has a smaller range of temperatures. Also, it has nice and mild weather: it has warmer winters than inland city, and cooler summers than inland city.

Fill in the blanks:

ser-zykov [4K]

Answer:

$8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$

So in blanks there will be 8, 9, 4, 3

Step-by-step explanation:

We have given that $8943=.....\times 1000+....\times 100+....10+....1=....10^3+....10^2+....10^1+....1$

We have to fill the blanks

We know that $8\times 1000=8000$

$9\times 100$

$4\times 10$

$3\times 1$

When we add all then

$8000+900+40+3=8943$

So in the blanks there will be 8 , 9, 4 , 3

We also know that $8000=8\times 10^3$

$900=9\times 10^2$

$40=4\times 10^1$

$3\times 1=3$

So $8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$
