<span>So we need to find two square numbers whos sum is equal to 130. That question has more than one answer because we can choose any two real numbers whos squared values sum is 130. For this example we have 81 + 49 = 130 and we can write them like this: 9^2 + 7^2 = 130. So the two numbers whos square values sum is 130 are 9 and 7. </span>
Problem 1
Answers: Choice A, choice D
The formula you use is
a & c/d = (a*d+c)/d
To convert from mixed number form to improper fraction form.
So,
6 & 2/3 = (6*3+2)/3 = (18+2)/3 = 20/3
And also,
8 & 1/5 = (8*5+1)/5 = (40+1)/5 = 41/5
===============================================
Problem 2
Answer: Reflection
Think of how mirrors cause a reflection and this should help you remember the term better. If we reflect point A over some line L, to get point A', then the distance from A to L is the same from A' to L also.
Answer:
8.5
Step-by-step explanation:
When you write out the data set, it looks like this:
5, 8, 8, 8, 8, 9, 9, 9, 10, 10
The median means the exact middle of the data set. In this case, it falls between the 8 and the 9, so the middle would be 8.5, so that's the median of the set. I hope this helps :)
The answer is B if they are fractions.
3/8-1/8=2/8 or simplified 1/4
Have a good day.
