Answer:

13

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

x = \sqrt{169} = 13

Karl set out to Alaska on his truck.
tester [92]

Answer:

<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>

Step-by-step explanation:

As we can see in the graph, the total distance that the truck can travel with 500 liters of fuel is ≅ 825 kilometres.

For answering the question properly, we use the Rule of Three Simple, this way:

Kilometres                Liters of fuel

825                              500

100                                 x

Solving for x, we have:

825 * x = 500 * 100

825x = 50,000

x = 50,000/825

x = 60.6 liters of fuel (61 rounding to the next whole)

x ≅ 61 liters of fuel

<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?
Elden [556K]
Slope =   (y₂- y₁) / (x₂- x₁)

Points  C( 3, -5) and D (6, 0)  compare to (x₁, y₁) and  (x₂, y₂)

Slope = (0 - -5) / (6- 3)  =   (0+5) / (3) =  5/3

Slope = 5/3

Equation of line given a slope and point,   y - y₁ = m(x - x₁)

m = 5/3,    let point C( 3, -5) = (x₁, y₁)

  y -  - 5 =  (5/3) (x - 3)
 
  y + 5  = (5/3)(x - 3)

   3(y + 5) = 5(x - 3)
  
    3y + 15 = 5x - 15

     3y =  5x - 15 - 15

     3y = 5x - 30

Hence the equation of the line is 3y = 5x - 30
