Suppose two bicyclists start at the same location.
DerKrebs [107]

Answer:

Step-by-step explanation:

See attachment.

If both cyclists travel for the same time and speed, they will have travelled the same distance.  Since one is headed north and the other east, we can see that the distance between them in one hour is the hypotenuse of a right triangle.  Each leg has distance x.  We can say x^2 + x^2 = (3\sqrt{2})^2

2x^2 =1 8

x^2 = 9

x = 3

They both rode 3 miles.

natita [175]

Answer:

3.75 of blue mixed with 12.5 of white is the correct answer

Step-by-step explanation:

We know the blue and white paints are a 1.5 : 5 ratio, and if we have a total of  16.25 by  1.5 by 5.  

1.5 * 2.5 = 3.75

------------------------

5 * 2.5 = 12.5

SO blue is 3.75 and white is 12.5

Answer:

Look at steps

Step-by-step explanation:

STATEMENT                                                     REASON


1.   AB = CD; AD = CB                               1.        Given

2. AC = AC                                                2.        Identity property

                                                                   (AC is the common side of the two triangles)

3.  Triangle ABC = Triangle ADC            3.        SSS (Side-Side-Side)


4. ∠1 = ∠4                                                  4.  Alternative interior angles are equal (Two lines are parallel and cut by transversal)

5.   DC || AB                                               5. Since alternative interior angles are (Two lines are parallel and cut by transversal)

                                                                       equal, the lines DC and AB are

                                                                        parallel by transversal property.


Thank you:)
