which describes a number that cannot be irrational?
Answer:
A number that can be written as the ratio of two integers .
Step-by-step explanation:
Irrational numbers are numbers those numbers that have infinite non-periodic decimals, that are reproduced in an unlimited way without an end point, without any part of the sequence being repeated. The set of irrational numbers, added to the rational numbers, configures the category of real numbers.
Irrational numbers include, for example, the famous number Phi (π), whose approximate value is 3.14 ..., extending its decimals indefinitely. These numbers are most often used in mathematical analysis.

Solve for the values of x and y. Round the answers to the nearest hundredth.
Answer:
x = 26, y = 19
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{ST}{NP}[/tex] = [tex]\frac{RS}{MN}[/tex] , substitute values
[tex]\frac{x}{13}[/tex] = [tex]\frac{32}{16}[/tex] = 2 ( multiply both sides by 13 )
x = 26
and
[tex]\frac{MP}{RT}[/tex] = [tex]\frac{MN}{RS}[/tex] , substitute values
[tex]\frac{y}{38}[/tex] = [tex]\frac{16}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 38 ( divide both sides by 2 )
y = 19

Marcus states that the polynomial expression 3x3 – 4x2y + y3 + 2 is in standard form. Ariel states that it should be y3 – 4x2y + 3x3 +2. Explain which student is correct and why.
Answer:
They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.

In a system of two linear equations, the lines represented by each equation have the same slope. Which could be the total number of solutions to the system of equation
Answer:
Please see explanation
Step-by-step explanation:
A system of linear equations in two variables represents two lines on graph.
When both the lines have same slope, there can be two cases
Same slope with different y-interceptsWhen two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.
Same slope with same y-interceptsWhen the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.

Select all irrational numbers.
Answer:
Option 1 , 2 & 5
Step-by-step explanation:
4 & 16 are perfect squares. So , 1/4 & 1/16 are also perfect squares. But 2 , 8 & 10 are not perfect squares. So root of 1/2 , 1/8 & 1/10 are irrational numbers.
Verification :-
1)[tex] \sqrt{ \frac{1}{10} } = \frac{ \sqrt{1} }{ \sqrt{10} } = \frac{1}{ \sqrt{2} \times \sqrt{5} } [/tex]
Hence , it is irrational.
2)[tex] \sqrt{ \frac{1}{8} } = \frac{ \sqrt{1} }{ \sqrt{8} } = \frac{1}{2 \sqrt{2} } [/tex]
So , it is irrational.
3)[tex] \sqrt{ \frac{1}{16} } = \frac{ \sqrt{1} }{ \sqrt{16} } = \frac{1}{4} [/tex]
So , it is rational.
4) [tex] \sqrt{\frac{1}{4} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2} [/tex]
So it is rational.
5) [tex] \sqrt{ \frac{1}{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } = \frac{1}{ \sqrt{2} } [/tex]
Hence it is irrational.

Castel and Gabriella are selling pies for a school fundraiser. Customers can buy apple pies and lemon meringue pies. Castel sold 6 apple pies and 4 lemon meringue pies for a total of $80. Gabriella sold 6 apple pies and 5 lemon meringue pies for a total of $94.
Could someone please walk me through the process of writing two systems of equations that represents the number of each type of pie????
Let x = cost of each apple pie; y = cost of each lemon meringue pie.
Thank you thank you so so much!
Step-by-step explanation:
Since Castel sold 6 apple pies and 4 lemon meringue pies for $80, we have 6x + 4y = $80.
Also Gabriella sold 6 apple pies and 5 lemon meringue pies for $94, we have 6x + 5y = $94.
6x + 5y = $94
- (6x + 4y = $80)
=> y = $14.
Therefore 6x + 5($14) = $94, 6x = $24, x = $4.
Hence each apple pie costs $4 and each lemon meringue pie costs $14.
Work out the mean for the data set below:
4.7, 4.2, 8.2, 9.5, 3.1
Answer:
5.94
Step-by-step explanation:
To find the mean, you need to add the numbers and divide it by however many numbers you have.
4.7 + 4.2 + 8.2 + 9.5 + 3.1 = 29.7
There are 5 numbers, so divide the sum by 5
29.7/5 = 5.94
The mean of the data set 4.7, 4.2, 8.2, 9.5, 3.1 will be 5.94.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers.
The data set is given below.
4.7, 4.2, 8.2, 9.5, 3.1
Then total number of the term are 5.
Then the mean will be
Mean = (4.7 + 4.2 + 8.2 + 9.5 + 3.1) / 5
Mean = 29.7 / 5
Mean = 5.94

With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?
Answer:
10 days

The Smith family is looking to rent a large truck for their upcoming move. With Rose's Moving, they would pay $40 for the first day plus $6 per additional day. With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?
Let the number of additional days = x
With Rose's Moving, they would pay $40 for the first day plus $6 per additional day.
40 + 6x
With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day.
90 + x
Comparing both
40 + 6x = 90 + x
6x - x = 90 - 40
5x = 50
x = 50/5
x = 10
The number of additional days = 10 days

The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52
