40 of the toys weren't dolls. The reason why is 5/8 times 64 is equal to 40.
Answer:
at least 6
Step-by-step explanation:
3(.5x+3)>12
1.5x+9>12
1.5>9
x>6
As shown in picture, AC is tangent to circle O
=> angle BAC = 90 deg
As the property of angle on circle:
=> BAY = (1/2) arc BY = (1/2) x 52 = 26 deg
=> angle YAC = angle BAC - angle BAY = 90 - 26 = 64 deg
Hope this helps!
