Which of the following numbers is not rational?

Mathematics
1 answer:
Feliz [49]2 years ago
3 0

Answer: √5

2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.

-3 is a rational number because it's an

integer and all integers are rational.

√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.

√5 is no rational! It's impossible to find a whole number multiplied by itself to give us 5 which means that it's

non-terminating and non-repeating.

Molodets [167]

Answer:

(a)The amount of fuel in dollars = $1.62

(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45

Step-by-step explanation:

Reid will be driving through Spain this summer. He did some research and knows that the average price of gas in Spain is approximately 1.12 euros per liter.

1 USD = 0.69 euros

We have to find the money that we should pay in order to get the same amount of fuel.

1 euro = \frac{1}{0.69}

1 euro = $1.45

So 1.12 euros = 1.12\times1.45 = $1.62

(a)The amount of fuel in dollars = $1.62

(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45
