rate
of depreciation, and t = time, in years. The current value of a car is $12,282.50. The car originally cost $20,000 and
depreciates at a rate of 15% per year. How old is the car?

Answer:

  (2, -3)

Step-by-step explanation:

Apparently, the equations are supposed to be ...

  • 4x +y = 5
  • 3x +y = 3

The solution for x can be found by subtracting the second equation from the first:

  (4x +y) -(3x +y) = (5) -(3)

  x = 2 . . . . . . . matches the second answer choice

Y can be found from either equation:

  y = 5 - 4x . . . . . subtract 4x from the first equation

  y = 5 -4(2) = -3

The solution is (x, y) = (2, -3).

Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120

Answer:

∠ PTQ = 70°

Step-by-step explanation:

The angles subtended by the radii and tangents to the circle , sum to 180°

∠ PTQ + 110° = 180° ( subtract 110° from both sides )

∠ PTQ = 70°
