Answer:
local calls per 1 long distance call.
Step-by-step explanation:
Local calls 
Long distance calls 
For 20 long distance calls local call ![=35 For 1 long distance calls local call [tex]=\frac{35}{20} =\frac{7}{4}](https://tex.z-dn.net/?f=%3D35%20%3C%2Fp%3E%3Cp%3EFor%201%20long%20distance%20calls%20local%20call%20%5Btex%5D%3D%5Cfrac%7B35%7D%7B20%7D%20%3D%5Cfrac%7B7%7D%7B4%7D)
I believe this question is missing an image. However, I will just tell how how to solve such question and you can apply this solution to the triangle you have.
In any given triangle, the sum of the measure of the three angles must be equal to 180 degrees.
Therefore, for a triangle pqr:
measure angle pqr + measure angle prq + measure angle rqp = 180 degrees
If you have one angle given, then the sum of the other two angles will be equal to 180 - measure of the given angle.
If you have two angles given, then the measure of the third angle will be equal to 180 - the sum of the other two angles.
Answer:
D. She used the beach's ball's diameter when she should have used the radius
Step-by-step explanation:
To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.
The formula she used is correct.
Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.
Radius (r) = ½(diameter) = ½(12) = 6 in.
This is where Emily made a mistake.
She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.
She should have gotten,
V = ⁴/3(3.14)(6)² = 904.32 cubic inches
Answer:
A The data is proportional and the unit rate per package is $8 This is because y= 8x
Step-by-step explanation:
/y relationship is no of packages = 1 x/ = total cost to ship = 8 = 8/1 = 16/2 = 24/3 = 32/4 means they are all proportional to 8/1 = 8 y = 8x see graph attached
Answer:
6π
Step-by-step explanation:
The period indicates after which time the sine wave repeats.
You divide 2π by the factor in front of your function variable. This is 1/3 for your function.
So 2π/(1/3) = 6π
