A tortoise traveled 1/6 kilometer in 7/8 hour. What was its average speed in kilometers per hour?
xxTIMURxx [149]

Answer:

4/21 kilometers per hour

Step-by-step explanation:

Since the tortoise traveled 1/6 kilometers in 7/8 hour we can divide 1/6 by 7 because 7/8 divided by 7 is 1/8 and get 1/42.Once we've done this we can then multiply 1/6 by 8 since 1/8 x 8= 8/8 or 1 hour and get 8/48 which simplifies to 4/21.

the length of the base of an isosceles triangle is x. The length of a leg is 4x-5. The terminator of the triangle is 35. find x.
vodomira [7]

Answer:

x= 5

Step-by-step explanation:

We are given;

  • Base of the triangle as x
  • Length of the leg is 4x-5
  • An isosceles triangle has two equal legs and a base.
  • The perimeter of the triangle is 35 (spelling mistake in the question)

To get the perimeter of a triangle we add the lengths of all sides of the triangle.

Therefore;

x + 4x-5 + 4x-5  = 35

9x - 10 = 35

9x = 45

  x = 5

Thus, the value of x is 5
