The gcf of 60 and 90<span> is the largest positive integer that divides the numbers 60 and 90 without a remainder. Spelled out, it is the greatest common factor of 60 and 90
The answer is 30 </span>
Jan 1 to Jan 31
swimming, every 3rd day : 3,6,9,12,15,18,21,24,27,30
band practice, every 4th day : 4,8,12,16,20,24,28
Both band practice and swimming : 12th day, 24th day....so 2 days
Answer:
the first box is proportional but the second is not
thus; y is (4/3)x for the first illustration
Answer: No, we don't have a right triangle
==========================================================
Explanation:
If a triangle with sides a,b,c makes the equation a^2+b^2 = c^2 true, where c is the longest side, then this triangle is a right triangle. This is the converse of the pythagorean theorem.
Here we have a = 2, b = 5 and c = 7.
So...
a^2+b^2 = c^2
2^2+5^2 = 7^2
4+25 = 49
29 = 49
The last equation is false, so the first equation is false for those a,b,c values. Therefore, we do <u>not</u> have a right triangle.
------------
In contrast, consider the classic 3-4-5 right triangle
a = 3, b = 4 and c = 5 would make a^2+b^2 = c^2 true because 3^2+4^2 = 5^2 is a true equation (both sides lead to 25).
