What much expression represents a rational number?

Pie

Answer:

$\displaystyle \frac{2}{7}+\sqrt{121}$

Step-by-step explanation:

<u>Rational Numbers</u>

A rational number is any number that can be expressed as a fraction

$\displaystyle \frac{a}{b}, \ b\neq 0$

for a and b any integer and b different from 0.

As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.

Let's analyze each one of the given options

$\displaystyle \frac{5}{9}+\sqrt{18}$

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

$\pi + \sqrt{16}$

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

$\displaystyle \frac{2}{7}+\sqrt{121}$

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

$\displaystyle \frac{3}{10}+\sqrt{11}$

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.

Correct option:

$\boxed{\displaystyle \frac{2}{7}+\sqrt{121}}$

Raul bought a PS5 and 5 games to go with it for $645. If the PS5 costs $500, how much did each game cost? $

tresset_1 [31]

Answer:

$29

Step-by-step explanation:

A PS5 costs $500. Subtract 500 from the total cost:

645 - 500 = 145

There are 5 games in total, costing $145 in all. Assuming all of them have the same price, simply divide 145 with 5:

145/5 = 29

Each game costs $29.

How to know when to use c2=a2+b2 or a2+b2=c2 in a question that doesnt have a shape

Viefleur [7K]

Step-by-step explanation:

A flagpole is 53 feet tall. Most of the time, this will be a vertical side of the triangle.

The flagpole and the ground are perpendicular to each other so they should form the legs of the triangles, this the triangle will be a right angle.

The rope will be the hypotenuse, the side opposite of the right angle.

. At a local bakery, all loaves of wheat bread come with 19 slices, while all loaves of rye bread come with 20 slices. If Grayso

zloy xaker [14]

To find the smallest number in common we multiply both numbers. Then we get 19 * 20 = 380 slices of bread. Sometimes we can divide this outcome by 2 and still have a good answer. In this case we would get 380 / 2 = 190 and that would be wrong.

Hence, the answer is 380.
