Answer:
B
Step-by-step explanation:
A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.
C is missing many combinations, it only has 4
D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option
We can use the process of elimination to conclude the answer is B.
Answer:
Step-by-step explanation:
Convert the mixed number into an improper fraction:
Now convert fractions so that their denominators are the same:
As the denominators are now the same, we can simply add the numerators:
Now convert back into a mixed number (if required):
<em><u>Two</u></em> of the four statements that Ana wrote are <em><u>correct</u></em>. Number 1, "AB is a diameter" is incorrect, and so is number 3, "SQ = 12 cm". AB is not a diameter because it is instead a chord. "ST , SP and SQ are radii" is correct because they are straight lines from the center of the circle to the circumference of the circle, which is the exact definition of radius. The third statemet is incorrect because since ST is a radius and it equals 6, that means all radii are equal to 6. SQ is a radius of circle S, so it should also equal 6, not 12. The last statement is correct because PQ is a diameter of circle S. By rule, the diameter is always equal to double of the radius. The radius is 6, so 6 x 2= 12.
