You play darts with a friend. the board has several concentric circles (same center). the central part of the board is called the bull’s eye and it is a circle with a 1-inch radius. just outside of that is the “inner ring”: it is the region inside a circle with a 3-inch radius and outside of the bull’s eye. how much harder is it to hit the bull’s eye than the inner ring?

Area of Bull's Eye:

A = π r²

   = π (1)²

   = π

Area of Inner Ring:

A = π r²

   = π (3-1)²

   = 4π

Ratio between Inner Ring and Bull's Eye:

It is 4 times harder to hit the Bull's Eye than it is to hit the Inner Ring

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.
