Xavier left his house at time zero and
Lady_Fox [76]

Answer:

Graph the points, (2,18) (7, 24) and (16, 0)

Step-by-step explanation:

Going to the store takes 2 minutes for 18 blocks, which is the first point

He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point

He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.

(This is assuming the graph is y for blocks and x for minutes)

Are the following triangles similar? Justify your answer.
Ber [7]

Answer:

Yes they are similar.

There are three similarity criteria for triangles.

The first one (AAA) , your case, says that two triangles are similar if their corresponding angles are equal.

The second one (SAS) says that two triangles are similar if two sides have lengths in the same ratio and the angles that are included in these two sides are equal.

The third one (SSS) says that two triangles are similar of all of their sides have lengths in the same ratio.

About the first criteria, you actually need only two corresponding angles to be the same, because the third will always be the difference between 180° and the two angles.

Remember that you CANNOT exceed 180° for the sum of the three angles of a triangle.

And remember also that similarity involves correspondence in sides and angles. Two triangles, with same angles, but mirrored, are not similar!

Yesterday I ran 9.6 miles at an average speed of 0.4 miles per 5 minutes. How long did it take me to run the 96 miles?​
Alexeev081 [22]

Answer:

Step-by-step explanation:

This is how we do it in college, I hope I can be of some help.

First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.

9.6 miles x <u>    5 minutes   </u> = <u>  48 miles x minute </u> = 120 minutes

                      0.4 miles          0.4 miles
