Answer:
<h2>2.6</h2>
Step-by-step explanation:
To solve this, we need to use the Pythagorean theorem to solve this.
The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.
3.4² + b² = 6.5²
11.56 + b² = 42.25
42.25 - 11.56 = b²
b = √30.69
b = 5.53985559 or about 5.5
4.9² + b² = 5.5²
24.01 + b² = 30.69
30.69 - 24.01 = 6.68
b = √6.68
b = 2.58456959666 or about 2.6
<h2>EDIT: the other user is incorrect, here's why</h2>
3.4 + 4.5 = 7.9
6.5² + 4.9² = 7.9²
66.26 doesn't equal 62.41
Answer:
$ 260.25
Step-by-step explanation:
$ 347 multiply by 25% or 0.25
You get $ 86.75
Take $347 - $86.75 = $ 260.25
Multiply 3/4 and 4 and you simply get 3 (these are the amount of tickets bought) Then divide the cost by tickets which results in 2.05
(3/4) x 4=3
6.15 / 3 = 2.05
Answer:
6
Step-by-step explanation:
Here is the answer but basically the work you just plug in 6 for A, 12 for B, and 5 for C..into the quadratic formula and solve from there
