The answer is 504 tickets must be purchase to guarantee a win.

Step-by-step explanation:

This is a permutation problem, which requires arrangement.

The first place finisher can be any of the nine entries, the second place finisher can be any of the remaining 8 entries and the third place finisher can be any of the remaining 7 entries.

Therefore ; 9*8*7=504

You will use 220ft of fencing to fence a rectangular plot of land. The length is 20 more than the width. What are the dimensions
PSYCHO15rus [73]
Set up the following equations:

L + W = 110
L - W = 20

110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.

We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

2L = 130

Divide both sides by 2 to get L by itself:

L = 65

The length of the rectangle is 65 feet.

Plug this value into the second equation:

65 - W = 20

Add W to both sides:

65 = 20 + W

Subtract 20 from both sides:

45 = W

The width of the rectangle is 45 feet.

A bike shop has 11 1111 red bikes, 3 33 blue bikes, 4 44 orange bikes, and 12 1212 silver bikes. For every 1 11 orange bike, the
zubka84 [21]

Answer:

C. Silver bikes

Step-by-step explanation:

Given that:

Number of red bikes at the bike shop = 11

Number of blue bikes at the bike shop = 3

Number of orange bikes at the bike shop = 4

Number of silver bikes at the bike shop = 12

Let us find the ratio of each bike with orange bikes to find the answer.

Orange bikes: Red bikes = 4 : 11

i.e. for every 4 orange bikes, there are 11 red bikes.

Orange bikes: Blue bikes = 4 : 3

i.e. for every 4 orange bikes, there are 3 blue bikes.

Orange bikes: Silver bikes = 4 : 12 = 1 : 3

<em>i.e. for every 1 orange bike, there are 3 silver bikes.</em>

<em></em>

Therefore, the answer is:

<em>C Silver bikes</em>
