Free point question! If you provide how you got your answer, I'll also give you Brainllest! Sarah is training for a bike race. She rides her bike 5 3/4 miles in 1/3 of an hour. What's Sarah's rate in miles per hour?

69/4 or 17.25 or 17 1/4

Step-by-step explanation:

if 5 3/4 miles is in 1/3 of an hour, and you are looking for miles per hour,

You need to multiply the mile distance by 3 to get the mph (miles per hour), because 1/3 times 3 is 1, and the 1/3 is miles, so 3 one thirds miles is 1 hour.

5 3/4 can turn into 23/4

because it is most likely easier to turn the mixed fraction into an improper fraction.

5 x 4 + 3

20 + 3

23     /4

23 x 3 = 69

and 69 should be over 4.

It can also be simplified to 17 1/4

because 17 times 4 is 68 and 1/4 times 4 is 1

68 + 1 is also 69.

The rate is 17.25 mph

Step-by-step explanation:

Rate=Distance/Time, where;

Distance=5 3/4=23/4miles

Time=1/3 hour

Rate=(23/4)/(1/3) = (23/4) * 3= 17.25 = 17 1/4  = 17.25

Rate = 17.25

answer: there are 453.592 grams in a pound.

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
