Quiz 2 Problem The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the double number line, how much does 333 bottles of water cost? dollars Report a problem

Cost of 3 bottles will be $7.5.

Step-by-step explanation:

Given:

According to double number line.

Cost of 4 bottles = $10

Based on this we need to find the cost of 3 bottles of water.

Solution:

Now we know that;

4 bottles = $10

1 bottle = Cost of 1 bottle

By using Unitary method we get;

Cost of 1 bottle =

So we can say that;

Cost of n bottles =

Cost of 3 bottles =

Hence Cost of 3 bottles will be $7.5.

Now we have drawn the double number line.

Bottom line(Line 1)  will be number of bottles:  

1   2   3   4   5   6  

Top line (Line 2) will be the cost of corresponding bottles:

2.5  5  7.5  10  12.5  15

positive

step-by-step explanation:

the quadrant is facing upwards

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
