what is the fraction of 0.79 in simplest form
The decimal 0.79 as a fraction in simplest form is 79/100, which cannot be simplified further.
To convert the decimal 0.79 into a fraction in simplest form, we have to write it as a fraction with a denominator that reflects the decimal's place value. Since 0.79 has two decimal places, it equates to 79/100. This fraction cannot be simplified further since 79 and 100 have no common divisors other than 1, thus 79/100 is the fraction in simplest form.

Look at the model that shows 1/2 =3/6. How does the number of parts in the whole affect the number of parts that are shaded?
Equivalent fractions represent the same portion of a whole, despite having different numerators and denominators. By increasing the number of equally divided parts of a whole and accordingly adjusting the number of shaded parts, you create equivalent fractions such as 1/2 and 3/6, which look different but represent the same amount.
Explanation:The question is addressing a concept in Mathematics, specifically the idea of equivalent fractions and how changing the number of parts in a whole affects those fractions. When you look at the model showing 1/2 = 3/6, you see that the whole is divided into different numbers of parts. The fraction 1/2 means that one out of two equal parts of the whole is shaded, whereas 3/6 indicates that three out of six equal parts of the whole are shaded.
To understand this, imagine dividing a shape into two equal parts. Shading one of these gives you 1/2. If you further divide each half into three parts, making six equal parts in total, and shade three, you still have the same amount shaded (which is half) but in terms of six parts now, hence 3/6. This shows that by increasing the number of parts into which the whole is divided, while maintaining the proportion of the shaded area, you increase both the numerator and denominator of the fraction proportionally, thus creating what is known as an equivalent fraction.

14.A company employee has to print 3145 pages, and the company's printer prints 85 pages per minute. The function f(x)=−85x+3145f(x)=−85x+3145 represents the number of unprinted pages x minutes after the printing begins.
What is the practical domain of function f?
all whole numbers from 0 to 37
all real numbers from 0 to 37
all real numbers from 0 to 3145
all multiples of 85 between 0 and 3145
The practical domain of the function f(x)=−85x+3145, which represents the number of unprinted pages x minutes after the printing begins, is from 0 to 37. Here, the value of 'x' are whole numbers since it represents time in minutes, and in this context, fractions or decimal amounts of minutes do not apply.
Explanation:In Mathematics, particularly in the topic of functions, the practical domain refers to the set of all possible values of x, for which the function is defined. In this particular problem, the function f(x)=−85x+3145f(x)=−85x+3145 represents the number of unprinted pages x minutes after the printing begins.
Given that the printer prints 85 pages per minute and there are 3145 pages to print in total, it will take the employee 3145/85 = 37 minutes to print all the pages. Therefore, the practical domain of this function f is all whole numbers from 0 to 37 inclusive.
Keep in mind, these are whole minutes. It may not make practical sense to consider fractions or decimals of minutes in this problem context as the printer operates at set whole minute intervals. So, the practical domain does not include real numbers between 0 and 37, only whole numbers.
So the practical domain of function f is all whole numbers from 0 to 37.

what is the system equation of y=1/4x : x+4y=8?
The system equation of y = 1/4x and x + 4y = 8 can be found by substituting the value of y from the first equation into the second equation and solving for x. The solution is x = 4 and y = 1.
Explanation:The given system of equations is y = 1/4x and x + 4y = 8.
To find the system equation, we can substitute the value of y from the first equation into the second equation.
Substituting y = 1/4x into x + 4y = 8 gives us x + 4(1/4x) = 8. Simplifying this equation, we get x + x = 8, which is equivalent to 2x = 8. Solving for x, we find x = 4. Substituting this value back into the first equation, we can solve for y and find y = 1.

do the following lengths form a right triangle?
a= 6.4, b= 12, c= 12.2
Answer:
It is not a right triangle,184.96 ≠ 148.84
Step-by-step explanation:
Definition of Pythagoras theorem:The square of the long side of a right-angled triangle is equal to the sum of the squares of the other two sides.
The formula is as follows:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Given, a= 6.4, b= 12, c= 12.2
Using the Pythagorean Theorem, [tex]a^{2} + b^{2} = c^{2}[/tex] ,you may determine if they form a right triangle:
[tex](6.4)^2 + (12)^2 = (12.2)^2[/tex]
40.96 + 144 = 148.84
184.96 ≠ 148.84

Aaron needs to hire a waiter. Waiter A is offering his services for an initial $25 in addition to $4.75 per hour. Waitress B is offering her services for an initial $30 in addition to $3.75 per hour. When will the two waiters charge the same amount of money?
At
hours, both waiters will charge the same amount, which is.....
Waiter A and waitress B will charge the same amount of money in 5 hours and which is $48.75.
What is the equation?The equation is defined as mathematical assertions that have a minimum of two terms containing variables or numbers that are equal.
As per the question, we can write the equations as:
For Waiter A, this is given by the equation 25 + 4.75h,
For Waitress B, the equation is 30 + 3.75h.
where h is the number of hours.
We can set up the equation 25 + 4.75h = 30 + 3.75h by equating the total amount each waiter will charge. Solving for h, we get:
25 + 4.75h = 30 +
4.75h - 3.75h = 30 - 25
h = 5
This means that at 1.05 hours, both waiters will charge the same amount of money.
The total amount they will charge is:
⇒ 25 + 4.75(5)
⇒ 30 + 3.75(1.05)
⇒ $48.75.
Thus, they will charge the same amount of money in 5 hours and which is $48.75.
