Two plumbers charge and initial fee and an hourly rate. The equation y = 100 + 30.0 models plumber A's fee, where y is the total charge, in dollars, and x is the number of hours worked. The table shown represents plumber B's total charge for different number of hours. Plumber B Hours Total Charges (5) 105 2 그 160 2 215 Which statement about the plurnbers' charges is true?

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
