Answer:

Rational

Step-by-step explanation:

We first have to define what these numbers mean:

Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.

Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.

An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....

Integers are real numbers that are whole numbers.

Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.

using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ
natita [175]

Answer:

The projected population in 2026 is of 699.3 million.

Step-by-step explanation:

Population:

The population, in x years after 2000, is given by the follwing equation:

y - 4.55x = 581

That is:

y(x) = 4.55x + 581

What is projected population in 2026?

2026 - 2000 = 26, so this is y(26).

y(26) = 4.55(26) + 581 = 699.3

The projected population in 2026 is of 699.3 million.

What is the square root of 72 simplified
Ket [755]

Answer: 6√2

Step-by-step explanation:

8 × 9 is 72.

8 can be simplied to 4 × 2.

And 4 can be simplified to 2 × 2.

So far there are three 2s and a 9.

9 can be simplified down to 3 × 3.

Theres a pair of 2s and a pair of 3s, so you multiply 2 × 3 and thats 6 so you put 6 on the outside of the radical. Theres one 2 leftover from all the simplifying so that goes inside the radical to give you 6√2

haru rides his bike from his home for 30 minutes at a fast pace. He stops to rest for 20 minutes, and then continues riding in t
Bezzdna [24]

Using the given information and what we know about linear equations, we will find the sketch below.

<h3>How to sketch a graph?</h3>

Here we need to analyze each part separately.

In a coordinate axis where the y-axis represents distance and the x-axis represents time, we will have that:

First, we know that he rides for 30 minutes at a given speed, this will be represented with an increasing linear function.

Then he stops for 20 minutes, this is represented with a horizontal line.

Finally, he returns the motion, but slower than before, so the slope of this line will be smaller than the first one.

So for 0 to 30 we have an increasing linear equation, then for 30 to 50 we have a constant horizontal line, then for 50 to 80 we have another increasing linear equation

The sketch can be seen below.
