Examine the following tables of ordered pairs and identify which relations are functions.Select two that apply

Answers

Answer:

Step-by-step explanation: B

The tables of ordered pairs representing relations that are functions are: A and C.

What is a Function?

If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.

Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.

Therefore, table A and C represent functions.

Si debes tomar 0.035 litros de agua por cada kg de peso al día, si pesaras 50 kg ¿Cuánta agua deberás beber en un día? ayuda porfavor

Answers

Answer:

Deberás beber 1.75 litros de agua en un día.

Step-by-step explanation:

De acuerdo a la información dada, puedes utilizar una regla de tres para encontrar la cantidad de agua que deberás beber en un día si pesas 50 kg dado que debes tomar 0.035 litros por cada kg:

 1kg     →     0.035 litros

x=(50*0.035)/1=1.75 litros

De acuerdo a esto, la respuesta es que deberás beber 1.75 litros de agua en un día.

When you ask what 75 minutes is in decimal, we assume you want to know what 75 minutes is in terms of hours.

There are 60 minutes in an hour. Therefore, 75 minutes in decimal is 75 minutes divided by 60 minutes (75 / 60), which equals 1.25. Thus, the answer to "What is 75 minutes in decimal?" is as follows:

75 minutes = 1.25 hours


When you ask what 174 minutes is in decimal, we assume you want to know what 174 minutes is in terms of hours.
