2 and 4 are false
Explain: it could not be certain unless there was 16 green and it is likely that red would be picked as it is the most common
Answer: The third one or C
Answer:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/3×4/4)+(1/4×3/3)=?
Complete the multiplication and the equation becomes
4/12+3/12=?
The two fractions now have like denominators so you can add the numerators.
Then:
4+3
12= 7/12
This fraction cannot be reduced.
Therefore:
1/3+1/4=7/12
the angle c is 90°, it is a right triangle. (you see from the picture).
the sum of the interior angles are 180° (in all triangles)
so
180 - 90 - 29 =
61° (angle A)
----------------------
90 + 61 + 29 = 180°
