8/15 times 3 1/3 and simplified

Step-by-step explanation:

Turn the second part into an improper fraction by multiplying the coefficient (the big 3) by the denominator of the fraction. You should get 3*3 = 9. Then add that number to the numerator of the fraction to get this:

Now, multiply directly across, so 8*10 over 15*3.

Now multiply out:  

You can simplify this into

Now, see how many times the denominator goes into the numerator evenly (1 time) and subtract that from the numerator to get

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
