Answer:

55.64

Step-by-step explanation:

The range finder is 92 feet from the building and 106 feet from the top of the building i.e. hypotheses

We will use the Pythagorean theorem:

x^2 = 106^2 - 92^2

= 11,236 -  8,464

= 2,772

= √2,772

x = 52.64978632

The height of the building:

h = x + 3

= 52.64978632 + 3

= 55.64978632

or

≈ 55.64 feet

MrRissso [65]

Answer:

Please see the attachment for double number line.

Explanation:

We are given cost of 4 water bottles is $10

We can write ,

Cost of 4 bottles = $10

Cost of 1 bottle = $2.5

Cost of 2 bottles =$5

Cost of 3 bottles = 3\times 2.5 = $7.5

Cost of n bottles = $2.5n

Now we draw the double number line.

Bottom line(Line 1)  will take as number of bottles:  

1   2   3   4   5   6  

Above line (Line 2) will show the cost of corresponding number of bottles:

2.5  5  7.5  10  12.5  15
