Answer:
330°
Step-by-step explanation:
The central angle:
360°×![\frac{11}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B12%7D)
=30°×11
=330°
They provide all the needed data...
n + d + q = $3.00 (they provide a ratio)
3:2:1 = $3.00 (let's enter the value of each)
3(.05) + 2(.10) + 1(.25)
.15 + .20 + .25
.60 = is the value of the ratio
let's divide the $3.00 by the .60 to get 5
let's now multiply the value of 5 to the ratio and solve the question...
3(5): 2(5): 1(5)
15 nickels
10 dimes
5 quarters

Answer:
Step-by-step explanation:
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
