If we draw in OX, OY, OZ we have two congruent right triangles, right angles at the tangent points.
We know XOZ is 132 degrees, which is the meaning of the arc measure
So YOX is half that, 66 degrees.
That leaves 180 - 90 - 66 = 24 degrees for OYX
Angle Y aka XYZ is double that, 48 degrees.
Answer: C
The first fraction is saying that 12 cups over 3 dollars is equal to 9 dollars over however many cups. To make it correct it would be 12/3 = C/9.
Answer:
d) 8
Step-by-step explanation:
We need the equivalence 1 lbs = 16 oz
We convert the 82 lbs to oz using the equivalence, that is:
82(16) = 1312
therefore 82 lbs are equivalent to 1312 oz, so the total of ounces we have is:
1312 + 11 = 1323
and that is the figure we have to divide by 9
1323/9 = 147
that is 147 oz
we can convert to lbs by dividing by 16
147/16 = 9.19
therefore the result is 147 oz or 9.19 lbs
