13/23% = 1300/23 (56.52)
<em>Therefore, 13 is 29% of 1300/23 (56.52)</em>
Step-by-step explanation:
1: change 'sin²A' and 'cos²B' into (1-cos²A)and (1-sin²A) respectively.
2:open the brackets and put signs accordingly.
3: cancel (-1) and (+1).
4: remaining is your answer.
Radian to degree conversion.
4(pi)/3 degrees= 4(pi)/3 × 180/pi radians
As pi radians= 180 degrees
Dividing both sides by pi :
pi / pi radian= 180/pi degrees
1 radian=180/pi degrees
4 × pi /3 × 180/ pi
pi and pi gets cancelled.
180/3= 60
4× 60
=240 degrees
Answer is option C.
2 of them is blue because since there is 16 marbles you multiply 1/8 by 2 and 2/16 so 2 marbles are blue
