Answer:
Step-by-step explanation:
we know that
The exponential function is of the form
where
a is the initial value
b is the base
In this problem we have
a=200 birds
b=100%+4%=104%=104/100=1.04
substitute
Let change of variables
where
b is the amount of birds in the flock
d is the number of days since the 200 birds started
104-32=72 brownies
72/32= 2.25
Ratio: 1 cookie:2.25 brownies
(i) XYZ = 180 - 64
= 116 degrees
Opposite angles in a cyclic quadrilateral add up to 180 degrees
(ii) YXZ = 23 degrees
Alternate angles in a segment are the same
(iii) OXZ = 26
XOZ = 64 x 2
= 128 degrees
The the angle at the centre is double the angle at the circumference.
180 - 128 = 52
OXZ = 52/2
= 26
Triangle OZX is an isosceles triangle

Your answer is... they ate 2/4 or 1/2 of the bag of popcorn.
Answer: I belive the answer would be 21 if it is 84 all you would have to do is divide it by the 4 sides and you get 21.
