The number of trucks calculated using system of equations is 30

Let :

Number of trucks = a

Number of cars = b

Charge per car = $4

Charge per truck = $6

We could form a system of equation thus:

  • a + b = 200 - - (1)
  • 6a + 4b = 860 - - (2)

From (1)

b = 200 - a

  • Substitute b = 200 - a in (2)

6a + 4(200 - a) = 860

6a + 800 - 4a = 860

2a = 860 - 800

2a = 60

a = 30

Therefore, the Number of trucks is 30

The terminal side of an angle θ in standard position passes through the point (3, 1). Calculate the exact values of the six trig
patriot [66]

Answer:

sin α = \frac{y}{r} = \frac{1}{\sqrt{10} }

cos α = \frac{x}{r} = \frac{3}{\sqrt{10} }

tan α = \frac{y}{x} = \frac{1}{3}

cot α = \frac{x}{y} = \frac{3}{1}

sec α = \frac{r}{x} = \frac{\sqrt{10} }{3}

csc α = \frac{r}{y} = \frac{\sqrt{10} }{1}

Step-by-step explanation:

If the point is given on the terminal side of an angle, then:

Calculate the distance between the point given and the origin:

r = \sqrt{x^2+y^2}

Here it is: \sqrt{3^2+1^2} = \sqrt{9+1} = \sqrt{10}

So we have:

x = 3

y = 1

r = \sqrt{10}

Now we can calculate all 6 trig, functions:

sin α = \frac{y}{r} = \frac{1}{\sqrt{10} }

cos α = \frac{x}{r} = \frac{3}{\sqrt{10} }

tan α = \frac{y}{x} = \frac{1}{3}

cot α = \frac{x}{y} = \frac{3}{1}

sec α = \frac{r}{x} = \frac{\sqrt{10} }{3}

csc α = \frac{r}{y} = \frac{\sqrt{10} }{1}
