Answer:
Step-by-step explanation:
Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.
That can be written as
x^(1/2)
...and when you take an even root of a negative number, there is no real answer. (2 is an even number).
Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.
So, A and C are the answer choices to select.
The square numbers smaller than 75 are 1, 4, 9, 16, 25, 36, 49, 64
1+49+25=75 seems to be the only set possible.
1+7+5=13
the answer is 13
Answer:
The answer is 25 and -25 :)

Answer:
30%
Step-by-step explanation:
Relative frequency : total number of diamonds / total number of cards drawn = 11/40=0.3
The answer is 30%
All triangles equal 180 so the answer would be set up as follows:
180-60-90 (right triangle) = 30 degrees
30 degrees is the answer
