R u asking the equations for the slopes of these points, the parallel the perpendicular slopes?? If m right tell me in the comments I'll answer you there.
There were 60 girls because you do cross multiplication (5 x 48 is 240 4 x 60 is 240)
2 2/5 minutes because 5 1/5 divided by 2 1/6 equals 2 2/5
Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: <em>N + 9</em>
N is equal to 12 in this equation
<em>12 + 9 is 21.</em>
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is <em>12(12)= </em>144
Hope this helps!
(By the way, I'm horrible at math so this could be completely wrong)
Draw an equilateral triangle with side lengths 5 inches each. Each interior angle is 60 degrees (this is true of any equilateral triangle).
Now draw an equilateral triangle of 10 inches each. The angles will be the same as before. We can see that the triangles are not congruent. Congruent triangles must have the same side lengths, but clearly the second one is larger than the first.
This is an example of why knowing solely the congruency of the angles is not enough to prove the triangles congruent or not. We would need to know something about the sides (whether they are congruent or not) to be able to determine overall triangle congruency.
