Use the law of sines....
sin51/x=sin90/67
x=(67sin51)/sin90
x=52.07
....
tan39=(h-1.8)/44
h-1.8=44tan39
h=44tan39+1.8
h=37.4 m
The distance between these points is 3.4 units
The answer is b , because 2/3 has more numbers in its decimal than the others
Answer:
The total number of hours = 35 hours.
Step-by-step explanation:
The annual fee of Calm Spa = $125
Per hour charge of Calm Spa = $10
Annual fee of Relax Spa = $230
Per hour charge of Relax Spa = $7
Now we have to find the number of hours for which both have same cost.
Let the number of hours = x
Thus, 125 + 10x = 230 + 7x
10x-7x = 230 – 125
3x = 105
x = 35
The total number of hours = 35 hours.
