Answer:
6 hours
Step-by-step explanation:
First set up the equation. Seeing the word "per", we know that this will be the variable. The repairman charges an initial fee of 37.50, so we add that fee to the total cost of every hour. To find how much Robin can spend, you set it equal to 450
65x + 37.50 = 450
Now subtract 37.50 from both sides because neither number has a variable, so you can subtract them to simplify the equation
65x = 412.5
To isolate x and find what it's equal to, divide both sides by 65 to get rid of the coefficient.
x = 6.34.
However the answer should be 6 because robin cannot afford a full or part of a 7th hour
The Pythagorean theorem computed shows that the length of the guy wire, to the nearest foot, is 207 ft.
<h3>How to solve the length?</h3>
Here, we have two similar right triangles, ΔABE and ΔCDE.
CD = 11 ft
DE = 2 ft
BD = 35 ft
First, find AB:
AB/11 = (35 + 2)/2
AB/11 = 37/2
Cross multiply
AB = (37 × 11)/2
AB = 203.5 ft
Then, apply Pythagorean Theorem to find AE:
AE = √(AB² + BE²)
AE = √(203.5² + 37²)
AE = 207 ft
Therefore, the length of the guy wire is 207 ft.
