2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000

compare

20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C

we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200


answer is C

Perimeter is 24.

Length is 4 greater than the width.

Let's use 'x' for width

we can write this as x+4   +   x+4    +    x    +    x

x+4 being the width+4     and    x being the width

There are 4 sides to a rectangle so you are adding 4 values

Two length and two widths

so  we can then combine  the two lengths to make 2x+8

and then combine the two widths to make 2x

Then put it together.       2x+2x+8= 4x+8

4x+8=24

Subtract 8 from both sides

4x=16

divide both sides by 4

x=4

The width is 4.

Simplify: 4sqrt400/4sqrt5. show your work
shusha [124]

4 sqrt(400) / 4 sqrt(5)

sqrt(400) =20

4 *20

--------

4 sqrt(5)

the 4's on the top and bottom cancel

20

--------

sqrt(5)


I was taught never to leave a sqrt in the denominator

so you need to multiply by sqrt (5) in the numerator and the denominator

20* sqrt(5)

--------

sqrt(5)* sqrt(5)


20* sqrt(5)

--------

5

= 4 sqrt(5)
