20/52 = b/100
20 x 100/52 x b
2000/ 52b
b = 38.5

Explanation:

b is a variable that stands for the unknown quantity
Write 20/52 as equal to b/100
Next we cross multiply 20 by 100 = 2000 and 52 by b = 52b
2000/52b is equal to 38.46 but roundest to the nearest tenth it is 38.5

Javier is considering two lawn care services. Premier Landscaping charges $15.00 for travel to the job site and $55.00 per hour
Wittaler [7]

Answer:

Time in which both companies charge same cost = 1.5 hour

Step-by-step explanation:

Given:

                                                        Fixed    Variable

Premier Landscaping charges          $15        $55

Ace Landscaping charges                               $65

Find:

Time in which both companies charge same cost:

Computation:

Assume in X time both companies charge same cost:

So,

Premier Landscaping total cost = Ace Landscaping total cost

⇒ $15 + $55(Time taken) = $65 (Time taken)

⇒ $15 = $65 (Time taken) - $55(Time taken)

⇒ $15 = $10 (Time taken)

⇒ Time taken = 1.5 hour

Time in which both companies charge same cost = 1.5 hour

Multiply top and bottom by cos x.

cos x / (cos²x + sin²x)
