Two joggers run 8 miles north and then 5 miles west. What is the shortest
Verdich [7]

The shortest distance they have to travel to return to their starting point is 9.4 miles.

Explanation

The joggers run 8 mile north and then runs 5 miles west. we have to calculate the shortest distance they have to travel to return to their starting point.

The distance traveled north and west respectively makes the height and base of a right angled triangle.

to find the shortest distance to the starting point, the hypotenuse has to be determined.

height h=8 miles

base b=5 miles

using pythagoras theorem

b^2+h^2=H^2\\5^2+8^2=H^2\\25+64=H^2\\89=H^2\\\\H=\sqrt{89} =9.433=9.4 miles

The shortest distance to the starting point is 9.4 miles

Change this equation, in standard form, to slope-intercept form: 2x + 3y = 18
Mandarinka [93]

Answer:

y = -2/3 + 18

Step-by-step explanation:

2x + 3y = 18       -----    here is the equation...

-2x          - 2x     -----    bring the 2x to the other side

3y = -2x + 18      -----    now you have to divide everything by 3 to get y by itself

y = -2/3 + 18       -----    Done!

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side i
PolarNik [594]

Answer:

  • 7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

<u>We have:</u>

  • P = a + b + c = 29
  • a = 2b - 5
  • c = b + 6

<u>Substitute values and solve for b:</u>

  • 2b - 5 + b + b + 6 = 29
  • 4b + 1 = 29
  • 4b = 28
  • b = 7

<u>Find a and c:</u>

  • a = 2*7 - 5 = 14 - 5 = 9
  • c = 7 + 6 = 13

<u>The sides are:</u> 7, 9, 13
