Use the formula c equals 5 / 9 f - 32 wherever represents degrees fahrenheit and c represents degrees in celsius to convert 77 degrees fahrenheit to celsius show your work

Value of 77 degree Fahrenheit is 25 degree Celsius.

Step-by-step explanation:

Given:

Fahrenheit = 77 (degree).

To convert in Celsius .

Formula of conversion to be used =  

Plugging the values of in the above equation.

We have,

⇒

⇒

⇒

⇒

⇒

⇒ (degrees)

So the value of 77 degrees in Fahrenheit scale is equivalent to 25 degrees in Celsius scale.

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
