Answer:

Never

Step-by-step explanation:

A Rational Number is a number of the form $\frac{p}{q}$ , p & q are integers and q ≠ 0.

An irrational number is all real number except rational numbers i.e. it is a non-repeating and non-terminating decimal number or it can not be expressed in a ratio of two integers.

Further, Natural numbers can be a rational number.

Also, all repeating and terminating decimals are rational.

The difference of rational number and irrational number is never a rational number. For example:

2 - √3 is always an irrational number where 2 is rational and √3 is an irrational number.

Hence addition and subtraction of rational and irrational number is never a rational number it will be irrational number always.

Licemer1 [7]

Answer:

17/49 or about 34.7%

Step-by-step explanation:

George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.

85/245 are pitchers.

you can simplify since 5 fits in both of those numbers

5*17=85

5*49=245

So, 17/49 or about 34.7%

About 150,000 people live in a circular region with a population density of about

morpeh [17]

Area of a circle = pi x r^2

Area of circle = 150,000/ 1578 = 95.06 square miles

95.06 = 3.14 x r ^2

Divide both sides by 3.14

R^2 = 30.27

Find the square root:

R = sqrt(30.27)

R = 5.5

The radius is c) 5.5 miles

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is $y = a(x-h)^2 + k$ where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have $y= \frac{1}{2}(x-5)^2 - 2$ which is the same as $y = \frac{1}{2}(x-5)^2 + (-2)$ and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
