Step-by-step explanation:
what is the main condition the lengths of the sides of a right-angled triangle have to fulfill ?
Pythagoras !
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle), a and b are the so-called legs (the sides enclosing the 90 degree angle).
only if there is a combination of the sides, for which the Pythagoras equation is true, do we have a right-angled triangle. otherwise not.
we also know CA = 18 - 7 - 3 = 8 cm
so, let's try
8² = 7² + 3²
64 = 49 + 9 = 58 wrong
7² = 8² + 3²
49 = 64 + 9 = 73 wrong
3² = 8² + 7²
9 = 64 + 49 = 113 wrong
so, there is no combination, where the Pythagoras equation is true, so it is NOT a right-angled triangle.
Answer:
1
Step-by-step explanation:
4/9 and -5/9 are 1 apart. This is because one of the numbers is positive and the other is negative, you have to make the negative number positive and add the two positive numbers together. In this case, 4/9+5/9=9/9. 9/9 is equivalent to 1. So, 4/9 and -5/9 are 1 apart.

Answer:
See explanation
Step-by-step explanation:
1. Determine the total distance heather has run in Km.
4.18km PER DAY for 197 days; 4.18 * 197 = 823.46km.
2. Can we just stop and say that this Heather chick MIGHT HAVE A PROBLEM?! Like, fr, she has run over 500 miles in half a year. . .she needs to see someone about that.
3. Divide the total distance by the distance of the track.
823.46/0.21 = 3921.23809524
4. Conclusion: Heather has run (roughly) 3,931.24 times around the track after the 197 day period of running 4.18km per day.
Based on the given fractions above which are 7/8 and 42/4, in order for us to know if they are both proportional is to do the cross multiplication. Let's say, we multiply 4 by 7 and we get 28. Divide 28 by 8 and the result is 3.5 and not 42. Therefore, we can say that these fractions are NOT proportional. Hope this helps.
