Answers

Answer 1

Answer:

The regular price for an item that is on sale for $38.40 is $48.

What is an inverse function?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

The output of a function is returned by the inverse function, which also returns the initial value.

Given the sale price of an item that has a regular price of R is,

S = R - 0.2R

the inverse function of R is

S = R(1 - 0.2)

S = R(0.8)

R = S/0.8

and the sale price is $38.40

regular price is,

R = S/0.8

R = 38.40/0.8

R = $48.

Hence the regular price is $48.

A una granja llegaron 54 ovejas 24 vacas 30 cerdos los cuales se quieren repartir en corrales con igual numero de animales de forma que haya la mayor cantidad posible en cada corral ¿cuantos animales posibles deben ir en cada uno de los corrales?

Answers

Answer: 6 animals should go in each pen.

Step-by-step explanation:

Total sheep = 54

Total cows = 24

Total pigs = 30

Highest number of animals are possible in each pen such that animals are distributed in pens with the same number = Greatest common divisior (54,24, 30)

54= 6 x 9

24= 6 x 4

30 = 6 x 5

So, Greatest common divisior (54,24, 30) = 6

Hence, 6 animals should go in each pen.
