the set is a {1/3, 2/3, 1, 4/3, ...} infinite set and {1/3, 2/3, 1, 4/3, ...} all numbers are subsets of the real numbers.

In mathematics, a real number is a continuous quantity value that can represent a distance along a line. The adjective real number in this context was introduced by Rene Descartes in the 17th century. Rene Descartes distinguished between real and imaginary roots of polynomials.

Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions (1/2, 2.5), and irrational numbers such as √3 and π(22/7) are all real numbers.

7 + (10 − 4)to the power 2 ➗ 4 ✖️1 over 2 to the power of 3

iragen [17]

Answer:

Step-by-step explanation:

=> $7+(10-4)^2 /4 (\frac{1}{2} )^3$

=> $7+(6)^2 / 4(\frac{1}{8})$

=> $7+36 / \frac{1}{2}$

=> $43 * 2$

=> 86

Mrs. Duggin walked every day for seven days. If she walked 9/10 of a mile each day for seven days, how many total miles did she

Molodets [167]

Answer:

Mrs. Duggin walked a total of $\frac{63}{10} \ miles.$ .

Step-by-step explanation:

Given:

Number of miles walked on each day = $\frac{9}{10} \ mile$

Number of days she walked = 7

We need to find the Total miles she walked using repeated addition method.

Solution:

Now we know that Repeated Addition means adding each group together and it is also known as Multiplication.

So we can Find Total miles she walked by adding Number of miles walked on each day with number of day times.

we can Find Total miles she walked by Multiplying Number of miles walked on each day with number of days.

framing in equation form we get;

Total miles she walked = $\frac{9}{10}+\frac{9}{10}+\frac{9}{10}+\frac{9}{10}+\frac{9}{10}+\frac{9}{10}+\frac{9}{10}= \frac{9+9+9+9+9+9+9}{10} = \frac{63}{10}\ miles$

Total miles she walked = $\frac{9}{10}\times7= \frac{63}{10} \ miles.$

Hence Mrs. Duggin walked a total of $\frac{63}{10} \ miles.$ .

1. Remote interior angles of ∠RPQ are: ∠PRQ and ∠RQP.

2. ∠RPS

3. ∠RPS, ∠QPV, and ∠QRU.

4. ∠RPS = ∠QPV [vertical angles]

5. ∠RPS + ∠RPQ = 180° [linear pair]

<h3>What are Remote Interior Angles of an Exterior Angle in a Triangle?</h3>

The remote interior angles to an exterior angle in a triangle are angles that lie directly opposite the exterior angle of the triangle and do not share a vertex or corner of a triangle with the exterior angle.

1. Remote interior angles of ∠RPQ are: ∠PRQ and ∠RQP.

2. ∠RPS is an exterior angle that has ∠PRQ and ∠RQP as its remote interior angles.

3. Exterior angles of the triangle are: ∠RPS, ∠QPV, and ∠QRU.

4. ∠RPS = ∠QPV [vertical angles]

5. ∠RPS + ∠RPQ = 180° [linear pair]

How do you use percent to convert numbers

mezya [45]

Answer:

percent is 1/100

you just multiply the percentage value by 1/100 to find its value

If for example you are taking 20% of 500, then 20*500/100= 100 is the answer
