Find 25 seconds in the table. That's between 20 and 30, right? So, find the median between 19 and 28:
19 + 28
----------   = 23.5
      2

That is around 24 deep knee squats per 25 seconds. Now, use the same method for 65 seconds:

51 + 58
----------  = 54.5
     2

That is around 55 deep knee squats per 65 seconds.
Now, explain the method using words. You might wanna use the words "average" or "mean" to describe that process above.

Are triangles DEF and LNM similar if LN equals 5 MN equals 3 DE equals 10 and FE equals 6
melisa1 [442]

Answer:

D.  Yes by SAS Similarity Postulate

Step-by-step explanation:

This is the answer because if you flip triangle LNM around to shape the DEF.  Then you will see that:

1. angle D is congruent to angle L

2. angle E is congruent to angle N

3. angle F is congruent to angle M

4. angle E and N are both 90 degrees

Because (DE and LN) and (MN and FE) are similar and (E and N) are 90 degrees, then we do not need (FD and ML) to tell if triangle DEF and triangle LNM is similar or not. They are similar.

We next need to figure out if the triangles are similar by SSS (Side-side-side) Similarity Postulate or SAS (side-angle-side) Similarity Postulate.  The SAS Similarity Postulate states that if you have 2 similar sides and 1 congruent angle, then the two shapes are similar. Right now we have 2 similar sides in (DE and LN) and (MN and FE) and 1 congruent angle that are both 90 degrees. This follows all the rules of the SAS Similarity Postulate, so that means that these two triangles are similar by SAS Similarity Postulate.

sleet_krkn [62]

Answer:

The answer is "Option C".

Step-by-step explanation:

Given value:

A) -69 > -425 \\\\B) -64 > -78 \\\\C) \ \ 23 < -39 \\\\D) -898 < 501 \\\\

In this question, the choice C is not true because 23 is greater than the -39.
