Check the picture below.
about ∡QML
well, QM is a diameter chord, and LM is a tangent line, the point of tangency is always a right-angle, as you see it in darkred there.
about ∡PMN
well, first off, let's notice the inscribed angle of 27°, by the inscribed angle theorem, that means the intercepted arc is twice that much, as you see it there in green.
QM is a diameter, so the arcQPM is 180°, if we subtract the 54° from arcPQ, we're left with the arcPM you see there of 126°.
by the tangent-chord angle theorem, ∡PMN is half of arcPM.
Out of 100% there is a possibility of 95% choosing a white marble since there are more white marbles than green marble there is a much higher possibility.
There is only a 5% of the marble being green.

divide 12 by 3
Answer:
-2x-7y=-4
Step-by-step explanation:
We want to add the two expressions
First we add the Left Hand Sides and do the same to the Right Hand Sides. This gives us:
(5x-9y)+(-7x+2y)= 1 +( -5)
Open the brackets
5x-9y-7x+2y=1-5
Regroup like terms
5x-7x-9y+2y=-4
-2x-7y=-4
The result of adding the two given expressions is -2x-7y=-4.
Answer:
7/2
Step-by-step explanation:
To get the number of 1/2 cup servings in 7/4 cups of rice you need to divide 7/4 by 1/2
7/4 ÷ 1/2
7/4×2/1----------------------multiplied by the reciprocal
14/4-----------------simplify by dividing both parts by 2
7/2----------------simplest fraction form
