The difference between the boiling and melting points of fluorine is 32 degrees C.
Alja [10]
Let the melting point be x degree C.
-188-x= 32
-x=32+188
-x=220
x= -220
Hence, the melting point of fluorine is -220 degree C.

ElenaW [278]
<span>Found a similar problem with the given table. 

Elapsed time (Minutes)   0    10   20   30    40    50   60   70   80   90
Rate (gallons / minute)   42   40  38   35    35    32   28    20   19   10

Because the interval is every 10 minutes, we will use 10 and multiply it to each rate and get the sum total.

42*10 + 40*10 + 38*10 + 35*10 + 35*10 + 32*10 + 28*10 + 20*10 + 19*10 + 10*10
420 + 400 + 380 + 350 + 350 + 320 + 280 + 200 + 190 + 100
2,990

There will be a total of 2,990 gallons in the tank after 90 minutes. </span>

What is the solution to the trigonometric inequality 2-3cscx) &gt; 8 over the interval 0 5x52x radians
Sholpan [36]

Answer:

The solution to the inequality is

x > 2π

Step-by-step explanation:

Given the inequality :

2 - 3cscx > 8

We want to find the solution to this.

2 - 3cscx > 8

-3cscx > 8 - 2

-3cscx > 6

cscx < -2

But cscx = 1/cosx

1/cosx < -2

cosx > -1/2

x > arccos(-1/2)

x > 2π
