Any number that can be written as a fraction and in which the numerator and denominator are both integers is referred to as a rational number. In other words, p/q can be used to represent a rational number when p and q are both integers and q is 0. It will be 0.25 and 0.5.
Explain about the rational numbers?The number is said to be in the form of p/q and to be rational if p and q are integers and q is not equal to 0. Examples of rational numbers are 1/3, 2/4, 1/5, 9/3, etc.A rational number is any number that can be written as the difference between two integers. For example, any integer is a rational number. The number one can be written as 10,000/10000, -2 over -2, or 1/1. This includes both ordinal and decimal fractions. A decimal fraction is one that has a denominator that is a power of 10. An example would be 0.25Hence, the rational numbers will be 0.25 and 0.5.

Luke's jump rope is greater than cooper's when the given mixed fraction was converted to an improper fraction and then a decimal by 0.35m.
What are mixed fractions?
The quotient and remainder of a fraction are used to represent it, making it a mixed fraction. For illustration, 2 1/3, wherein 2 has been the quotient but 1 is indeed the remainder, is a mixed fraction. A mixed fraction is a combination of both a complete number and a recognized fraction.Converting each mixed fraction to an improper fraction and then decimal to compare between two values, we get-
Cooper's jump rope length= [tex]4\frac{2}{5}[/tex] = 22/5 =4.4 m
Luke's jump rope length = [tex]4\frac{3}{4}[/tex] = 19/4 = 4.75 m
Luke's jump rope is greater than cooper's by 4.75-4.4 =0.35m
Comparing both lengths, we get that Luke's jump rope is greater than cooper's when the given mixed fraction was converted to an improper fraction and then a decimal by 0.35m.

5. Which fraction is NOT equal to 8/7 ?
A square number is the result of multiplying an integer or number by itself exponentially. Square numbers are always positive numbers. Positive sign (+) is produced when the negative sign is multiplied by itself. Option B: 64/49 is not equal to 8/7
What are Squares and Square Roots?In mathematics, the operations squares and square roots are the opposite. A number's square represents the number that requires to be multiplied by itself to return to its original value, whereas a number's square represents the number that has to be multiplied by itself to return to its true value. The square of some other natural number is a perfect square, often known as a square number. The result of multiplying a number by itself is the square root of that number. It is possible to couple the perfect square's prime factors. Making the prime factor pairs is the first step in determining the square root. The product of these components is then determined by selecting one element from each pair.The square root of the ideal square can be discovered using this technique.Option B: 64/49 is not equal to 8/7
64/49 = (8/7) ^2 but not 8/7
whereas all the other options:
16/14 = 8/7

Two companies are competing for a contract to make the programs for the high school football games. Howie's Printing charges a $19.99 fee for printing and $0.25 for each program printed. Mint Print charges a $29.99 fee for printing and $0.10 for each program printed. For what number of programs will Howie's Printing cost more than Mint Print?
i need this now tooooooo
Considering the definition of an inequality, for more than 67 number of programs Howie's Printing will cost more than Mint Print.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values, in addition to certain known data.
The solution of an inequality is the value or set of values that the variable has so that the inequality is fulfilled.
Number of programs in this caseBeing "x" the number of program printed, you know that:
Howie's Printing charges a $19.99 fee for printing and $0.25 for each program printed. → Howie's Printing charges= 19.99 + 0.25xMint Print charges a $29.99 fee for printing and $0.10 for each program printed. → Mint Print charges= 29.99 + 0.10xIf Howie's Printing cost more than Mint Print, the inequality that expresses the previous relationship is
Howie's Printing charges > Mint Print charges
19.99 + 0.25x > 29.99 + 0.10x
Solving:
0.25x - 0.10x > 29.99 - 19.99
0.15x > 10
x > 10÷0.15
x > 66.67≅ 67
Finally, the number of programs is more than 67.

For the right triangles below, find the exact values of the side lengths a and h. If necessary, write your responses in simplified radical form. pad 309 8 Х X S 45° 0 60° 3 h
First Triangle:
This is a special right-angled triangle and is known as 45°-45°-90° triangle
To solve for any side length, we can use the following procedure.
As you can see, the sides opposite to the 45° are equal and in this case, both are 3
Then the side opposite 90° will be
[tex]3\sqrt[]{2}[/tex]Therefore, the side a = 3√2
Second Triangle:
This is a special right-angled triangle and is known as the 30°-60°-90° triangle.
To solve for any side length, we can use the following procedure.
As you can see, the side opposite the 30° is the smallest.
The side opposite the 60° is 2 times the side 30°
The side opposite the 90° is √3 times the side 30°
For the given case, we want to know the side opposite of side 30°
We are given the side opposite the 60° that is 8
[tex]\begin{gathered} 2h=8 \\ h=\frac{8}{2} \\ h=4 \end{gathered}[/tex]Therefore, side h = 4

T-Mobile:
Verizon:
Using an algebraic method, determine how many minutes the two plans will cost the same.
T-Mobile charges a base fee of $15 per month plus $0.05 for each minute. 300 minutes long would you need to call for them to charge the same amount.
Given that,
T-Mobile charges a base fee of $15 per month plus $0.05 for each minute you are on the phone for any long-distance call, while Verizon has a basic rate of only $10 per month but charges $0.10 for long-distance calls.
We have to find how long would you need to call for them to charge the same amount.
We can write the equation as
15+0.05x=0.10x
0.05x-0.10x=-15
-0.05x=-15
0.05x=15
x=15/0.05
x=300 minutes
Therefore, 300 minutes long would you need to call for them to charge the same amount.

Point C' is the image of C(-4,-2) under a reflection across the y-axis.
What are the coordinates of Cl?
After reflection along the y-axis, the coordinates of C' is (4, -2).
What is a reflection in a graph?A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the shape across the line to graph a reflection. A function's graph is transformed over the x-axis or the y-axis in a reflection (or both). The function keeps its basic form, but if a negative sign is added at the right spot in the equation, the graph will flip over one of the axes or the other.So, the coordinates of C':
We already know that C(-4,-2) lines on the 3rd quadrant as in the 3rd quadrant (-x, -y) are found.When reflecting upon the y=axis, the C' will be seen in the 4th quadrant.We know that the 4th quadrant (x, -y).So, the coordinates of C' will be (4, -2).(Refer the the graph attached below)

difference: Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us how much a number differs from the other. The aim of finding the difference in math is to tell how many numbers lie between the two given numbers.
To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value. The product of this sum is the difference between the two numbers. Therefore the difference between 45 and 100 is 55.
G(x)=-3x-8
G(____)=10
Answer: x = -6
Step-by-step explanation: First, you want to set up the equation as -3x-8 = 10, as we’re trying to find x. Then you would add 8 to both sides to get rid of the -8. This leaves you with -3x = 18. Then you would divide by -3 on both sides to isolate the x. This leaves you with x = -6. If you plug -6 back into the equation:
-3(-6) -8
18-8
