Yes, 1/2 is equivalent to 4/8, because 4/8 reduced to simplest form is 1/2.
Percent change = [(45 - 60) / 60] x 100 = -25 % (decrease)
Answer:
Not a right triangle.
Step-by-step explanation:
If this triangle is a right triangle, then the Pythagorean theorem would work on it. According to the Pythagorean theorem, , so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal: . We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.
Here first we have to understand which place is 10 thousand.
6- hundred thousand
2- ten thousand
0- thousand
0- hundred
0- ten
0- one
so as we can see 2 is in ten thousands place.
Now rounding ten thousands place is done by looking up to thousands place.
If the digit at thousands place is 5 or greater than 5 then we change our ten thousands value to one digit higher else it remains same.
Here we have 0 at thousands place , which is less than 5 , so we keep the number as it is.
Answer: 620, 000
