Answer:
9
Step-by-step explanation:
Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t
such that
t = c + f .... eq 1
ratio of c to t = 7 : 16 = 7/16
Therefore, t = 16, c = 7
substitute the value of t in eq 1
16 = 7 + f
f = 16 - 7
f = 9
The regular polygon has 9 sides
Step-by-step explanation:
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
we see that the visible 7 numbers have a range of 50-17 = 33.
that means that x has to make sure that the range really is 69.
so, we have indeed 2 choices : x can be the lowest value (with a difference of 69 to the highest value, 50), or x can be the highest value (with a difference of 69 to the lowest value, 17).
x as the lowest value :
x = 50 - 69 = -19
x as the highest value :
x = 17 + 69 = 86
All you need is the double angle identity:
So we have
Apply the identity again to the squared term:
Answer: A <em>plane </em>
