What is rational number?
Rational numbers are those numbers which include natural numbers, whole numbers as well as integers. And it is written in the form of a/b where a and b are integers. Sometimes, the values of the denominator is one then the given number is not fraction.
Here,
The whole numbers that are between 25 and 50 and have a difference of 4 their digits will start from 26 and next number will be at the gap of 4 that is 30 and so no :
all whole numbers = 26, 30, 34, 38, 42, 46.
Therefore, whole numbers that are between 25 and 50 and have a difference of 4 are 26, 30, 34, 38, 42, 46.

Find the 60th term of the arithmetic sequence −29, -49, −69,
We see, the second number is 20 less than the first number, the third number is 20 less than the second number, ..
So, the pattern is : We minus 20 from a term to get the next term right after.
From the 1st term to the 60th term, there are 59 spaces.
Therefore, the 60th term = -29 - 59 x 20 = -1209

Option B: 4x²-x+3
(4x³ + 11x² + 0x + 9) + (x+3) [here, we will include 0x to do long division]
Divide 4x³ by x to get first term of the quotient, 4x³
Then, take 4x² and multiply it with 3 and you will get 4x² + 12
Subtract 4x² + 12 from 4x³ + 11x².
Then, you will get the remainder as -x² + 0x
Now you have to repeat the same same process, divide -x² by x to get second term of quotient, -x
Then take -x and multiply with 3 and you will get -x²- 3x
You will get the remainder as 3x+ 9
Divide 3x by x to get the third term of quotient, 3
Then, take 3 and multiply with 3 and you will get 3x + 9

Explain how you know that the sum of 26.541 and 14.2 will be greater than 40.
The sum of 26.541 + 14.2 is greater than the integer 40, as the sum is equivalent to 40 + 0.741.
How to prove that the sum of two real numbers is greater than an integer
In this problem we need to compare the sum of two real numbers with an integer, also a real number. The two real numbers can be written as the sum of an integer and excess decimal part. Then, the given sum can be rewritten as:
x = 26.541 + 14.2
x = (26 + 0.541) + (14 + 0.2)
This sum must be compared with an integer, 40.
x = (26 + 14) + (0.541 + 0.2)
x = 40 + 0.741
Then, by direct comparison, we see that the sum of 26.541 + 14.2 is greater than 40.

How do you represent a equation on a graph?The act of displaying linear equations with one or two variables on a graph is known as "graphing linear equations." A linear equation is a one-degree equation, meaning that the variable's highest power or exponent value may never be more than 1, under any situation. Finding the values of the variables in a linear equation is known as solving it. The graphical approach is one way to solve linear equations, which can have one or two variables.
They are algebraic equations with 2 variables of maximum power 1 and real constants in each term. The linear equation is shown in y=mx+b form, sometimes referred to as the y-intercept form.

Number of Questions 4 7 Time (in minutes) 6 ? How much time does it take to complete 7 questions? 3 minutes 5 minutes, 30 seconds 9 minutes 10 minutes, 30 seconds
Through direct proportionality, we calculated that Seven questions will be answered in 10 minutes and 30 seconds.
Seven questions will need to be answered in 10 minutes and 30 seconds.
Direct proportionality: What is it?
The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. In mathematics, a straight line is used to express direct proportionality, and its equation is of the form y = kx , k = y/x, where [k] is the constant.
The assumption is that the time it takes to finish each question and the number of completed questions [y] are inversely proportional to one another.
The time [x] it takes to complete them is directly proportional to the number of questions [y] that are answered. As a result, y = kx, k = y/x, and y is directly proportional to x.
Thus, we can write:
y₁/x₁ = y₂/x₂
Substituting the values,
4/6 = 7/x₂
x₂ = (7 x 6)/4
x₂ = 21/2
x₂ = 10.5
x₂ = 10 minutes 30 seconds
Therefore, Seven questions will be answered in 10 minutes and 30 seconds.

Answer:
Step-by-step explanation:
60 divided by 4 is 15 so 1/4 of an hour is 15 minutes. so three fourths is 45 minutes and one hour and a half is the extra hour that has not been touched so add the last 15 min from the 3/4 onto that so it still has 1 hour and 45 minutes to bake
Answer:
It still has to bake for 1 3/4 hours
Step-by-step explanation:
So, the way I do it, you start by making 2 1/2 an improper fraction, which would be 5/2. Then, you have to get it so 5/2 and 3/4 have common denominators. The fastest way to do this is to multiply the denominator 2 by 2, which means you have to do the same to the numerator. So, you have 10/4-3/4, which equals 7/4. Now, you can simplify. 7/4 = 1 3/4

if during a typical week susan bowls 16 games, what is the probability that her average score for the week is between 220 and 228?
The probability that the average score for the week is between 220 and 228 = 0.7641
Susan's score on bowling follows Normal Distribution.
Average score or mean, μ = 225
Standard Deviation, σ = 13
Number of times Susan bowled, n = 16
Since the scores follows Normal Distribution, the z-score = (x-μ)√n/σ
When the score, x = 220,
z = (220-225)√16/13
= -20/13
= -1.538
When the score, x = 228,
z = (228-225)√16/13
= 12/13
=0.923
Hence The probability that the average score for the week is between 220 and 228 = P(220 < x < 228)
= P(-1.538 < z < 0.923)
= P(z < 0.923) - P(z < -1.538)
= (0.5 + 0.3212) -( 0.5 - 0.4429) [From the z-tables]
= 0.7641
