To solve, lets convert the number so that they both have the similar exponents.

$2*10^{-24} =20000*10^{-28} 

$

in comparing 20,000*10^-28 and 9*10^-28, we can see that one is nearly 2,000 times bigger than the other

20,000/9=2222

Answer= C

Anybody know the answer to this

Phoenix [80]

Answer:

$x = 2$

Step-by-step explanation:

The blue line represent the full line length.

We can add the parted black segments together and set it equal to the line.

$11 + 6x - 2 = 6x + 9$

$10x + 1 = 6x + 9$

$10x = 6x + 8$

$4x = 8$

$x = 2$

A scale of 1 cm to 8 km is used for a map.

-Dominant- [34]

Answer:

40 km^2

16 cm^2

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = scale factor x scaled area

8 x 5 = 40 km^2

Scaled area on the map = 128.8 = 16 cm^2
