Deanna uses only fruit juice and sparkling water to make punch for a school dance. she uses 6 liters of fruit juice. she uses 0.6 as much sparkling water as fruit juice.

how much fruit punch does she make?

3.6 liters

Step-by-step explanation:

You know that:

- She uses 6 liters of fruit juice.

- She uses 0.6 as much sparkling water as fruit juice.

Therefore, let's call x the amount of fruit punch she made.

Keeping the above on mind, you can solve the problem by multiplying the 6 liter of fruit juice she uses by 0.6.

Therefore the result is:

Deanna makes 9.6 liters of fruit punch.

Step-by-step explanation:

We are given that Deanna uses 6 liters of fruit juice and 0.6 as much sparkling water as fruit juice.

We are to find out the amount of fruit punch she makes.

Liters of fruit juice used = 6

Liters of sparkling water used = 0.6 * 6 = 3.6

Liters of fruit punch made = 6 + 3.6 = 9.6 liters

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

have a nice day

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:
