The formula to convert fahrenheit to celsius is c=5/9(f-32). convert 12°c to fahrenheit. round to the nearest degree

C = 5/9(F - 32)

Since we want to convert 12 degrees Celsius into Fahrenheit, substitute 12 for C in the equation and solve for F.

12 = 5/9(F - 32)

Distribute 5/9 inside the parentheses.

12 = 5/9F - 160/9

Add 160/9 to both sides.

268/9 = 5/9F

Divide both sides by 5/9.

F = 268/9 * 9/5 = 2,412/45 ==> 53.6

The question wants the final answer rounded to the nearest degree (ones), so the final answer is 54 degrees Fahrenheit.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
