8*10^4 is how many times as large as large as 4*10^-5

D. 2 . 10^9

Step-by-step explanation:

( 8 * 10^4 ) / ( 4* 10^-5 )

( 8*10^4 ) 10^5 / ( 4 )

2 * 10^ 9

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
