Answer:
the number of single room is 27 and the number of double room is 53
Step-by-step explanation:
Let x is the number of single room
Let y is the number of double room
We know that:
x + y = 80 <=> x = 80 -y (1)
80x +90y= 6930 (2)
Substitute (1) in (2) we have:
80 (80 - y) + 90y = 6930
<=> 6400 - 80y +90y = 6930
<=> y = 53
> x = 80 - 53 = 27
the number of single room is 27 and the number of double room is 53
Answer:
613 meters
Step-by-step explanation:
1)
cos(50 degrees)=324/x
x*cos(50 degrees)=324
x=324/cos(50 degrees)
x=around 504.1
2)
cos(35 degrees)=324/x
x*cos(35 degrees)=324
x=324/cos(35 degrees)
x=around 395.5
now lets find the distance in between the two people:
Distance from Shively to the tower
tan(50 degrees)=x/324
x=324*tan(50 degrees)
x= around 386.1
Distance from Sparzak to the tower
tan(35 degrees)=x/324
x=324*tan(35 degrees)
x=around 226.9
total distance=386.1+226.9=613 meters
