If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

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

50 kg  →              x

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.
