Answer:
5/18 is a rational number because a rational number is any integer,fraction terminating decimal,or repeating decimal.
Answer:
The ratios are as follows for the given angle:
sineX=opposite/hypotenuse
cosineX=adjacent/hypotenuse
tangentX=opposite/adjacent
Insert the appropriate values for each:
7.) sinZ=24/40
8.) sinC=14/50
9.) cosZ=24/30
10.) tanC=27/36
11.) cosZ=12/15
12.) cosC=27/45

Answer:
The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is 
Step-by-step explanation:
We are given:
Distance = 100 m
Time = 20 s
We need to find:
Speed
The formula used is: 
Putting values and finding the expression

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is
