Answer:
A)(Always)Rational
B)(Always)Rational
C)(Sometimes)Rational
This is because Square roots are generally irrational(like the 
) and the product and difference of rational numbers should always be rational!
Hope this helps!
Sorry, cannot explain more ... :(
P.S. Stay Safe!
Answer:
d. accuracy
Step-by-step explanation:
In measurements, accuracy is a term that is used to describe the closeness of a measured value to the actual or true value. While precision describes how close different measured values are to each other.
Thus when a measured value is accurate, it implies that the value is very close or almost equal to the true value. The correct answer to the question is is option D.

Answer:
c
Step-by-step explanation:
just took the test
Rick has 1 1/3, or 4/3, pounds of sugar.
He needs to pour 1/4 of this amount into the bowl.
4/3 * 1/4 Multiply the numerators and the denominators
(4*1) / (3*4) = 4/12 Simplify, 4/12 can be simplified to 1/3.
He poured 1/3 pound of sugar.
Now, for flour, we need to find 1/4 of 2/3, using the same process:
(2/3) * (1/4) = (2*1) / (3*4) = 2/12 = 1/6
He poured 1/6 pound of flour
