How do you work out a 1/3 of something?
By dividing any number 3 to simplify the expression.
What is simplifying an expression?
To simplify an expression, create a similar expression devoid of any similar terms. Therefore, we will rewrite the expression using the fewest number of terms possible.
When you simplify an expression, your goal is essentially to make it as simple as you can. There shouldn't be any additional multiplying, dividing, adding, or subtracting to be done at the conclusion.
One third is one part of three equal parts. When you split an object or number into thirds, you divide it by three.
Thirds are calculated by dividing by 3.
For example: One third of 24 =1/3 of 24 = 24/3 = 8.
Hence, by dividing any number 3 to simplify the expression.

What is the formula for an isosceles right triangle?
An isosceles right triangle is a special type of triangle that has two equal sides and one right angle.
It can be described using the Pythagorean Theorem, which states that the sum of the squares of the two legs of a right triangle are equal to the square of the hypotenuse. Mathematically, this can be expressed as a^2 + b^2 = c^2, where a and b are the lengths of the two legs, and c is the length of the hypotenuse.
In an isosceles right triangle, two of the sides must be equal, so a=b. This means that the Pythagorean Theorem simplifies to 2a^2 = c^2. Solving for a gives a = sqrt(c^2/2). This is the formula for the sides of an isosceles right triangle.
As an example, consider a triangle with a hypotenuse of length 5. Substituting this into the formula gives a = sqrt(25/2), or a = 5/sqrt(2). This means that both of the legs of the triangle have length 5/sqrt(2).

Consider the two linear functions reprsented by the table and the equations
Find the rise and run to determine the slope. Look up the y-intercept (the point where the line crosses the y-axis) Insert the value into the formula f(x)=mx+b.
How do you solve if an equation is a function?For any input, a function will only have one or no outputs. The equation does not define a function if a given input has more than one output. Each value of x must have a maximum of one output value of y in order to be considered a function. To determine the slope of a graphed function, use the average rate of change formula.
The average rate of change from a to some other value x is what determines the instantaneous rate of change at some time[tex]x_{0} =a[/tex]. The average rate of change from x=a+h to x=a is y x = f(x) f(a) x a =f (a + h) f( a ) h if h = 0 and a = f ( a + h ) f (a) h are set.

Answer:
[C] 3 3/4 Miles
Step-by-step explanation:
Given:
Zoe jogs 3/4 of a mile every 1/5 of an hour.
How many miles does Zoe jog per hour?
[A] 3/20 Miles
[B] 4/15 Miles
[C] 3 3/4 Miles
[D] 6 2/3 Miles
Solve:
Since, Zoe jogs 3/4 of a mile every 1/5 hour. And 5/5 = 1 hour.(Also known as 60 minutes) Which means 1/5 is 12 minutes. In order to find how much Zoe jogs per hour, we have to multiply.
Knowing that;
1/5 = 12 minutes
2/5 = 24 minutes
3/5 = 36 minutes
4/5 = 48 minutes
5/5 = 60 minutes (1 Hour)
Hence, 3/4 Multiply by 5.
3/4 × 5 = 3.75 = 15/4 = 3 3/4
As a result, Zoe jogs 3 3/4 miles per hour.

Answer:
A quadratic equation is an equation of the form ax^2 + bx + c = 0, where a, b, and c are constants, and x is a variable.
The equations that are quadratic equations are:
(i) x^ 2 + 6 x − 4 = 0
(v) 2 x^ 2 − √ 3 x + 9 = 0
The equations that are not quadratic equations are:
(ii) √ 3 x^ 2 − 2 x + 1/ 2 = 0
(iii) x^ 2 + 1/ x^ 2 = 5
(iv) x − 3/ x = x ^ 2
(vi) x ^ 2 − 2 x − √ x − 5 = 0
(vii) 3 x ^ 2 − 5 x + 9 = x 2 − 7 x + 3
(viii) x + 1 x = 1
In (ii) √ 3 x^ 2 − 2 x + 1/ 2 = 0 the coefficient of x^2 is not a real number.
In (iii) x^ 2 + 1/ x^ 2 = 5 the equation is not in the form of ax^2 + bx + c = 0
In (iv) x − 3/ x = x ^ 2 the equation is not in the form of ax^2 + bx + c = 0
In (vi) x ^ 2 − 2 x − √ x − 5 = 0 the equation is not in the form of ax^2 + bx + c = 0
In (vii) 3 x ^ 2 − 5 x + 9 = x 2 − 7 x + 3 both sides are not equal
In (viii) x + 1 x = 1 the equation is not in the form of ax^2 + bx + c = 0
So, the equations that are quadratic equations are (i) and (v).

On Monday you ran to a playground 2 1/4 mi from your house. It took you 22 min to run there and 25 min to run back home. on Tuesday you ran the entire 4 1/2 mi at a constant speed of 6 1/4. What must you do to compare the times it took to go to and from the playground each day
You can conclude that it took you less time on Tuesday to run to and from the playground than it did on Monday.
What is the distance?Distance is defined as the product of speed and time.
To compare the times it took to go to and from the playground each day, you need to calculate the total time for each day.
On Monday, it took 22 minutes to run to the playground and 25 minutes to run back home, for a total time of 47 minutes.
On Tuesday, you ran the entire 4 1/2 miles at a constant speed of 6 1/4 miles per hour, so you can use the formula:
distance / speed = time.
In this case, 4.5 miles / 6.25 mph = 0.72 hours or 43.2 minutes.
Therefore, you can see that it took you 47 minutes on Monday, and 43.2 minutes on Tuesday to run to and from the playground.
Hence, you can conclude that running to and from the playground took you less time on Tuesday than it did on Monday.

When y changes directly as x, the variation constant is 5/4.
What is constant of variation?In a direct variation, the ratio of two variables; in an inverse variation, the product of two variables. The constant of variation k is used in the direct variation equations = k and y = kx, as well as the inverse variation equations xy = k and y =. A constant of variation (k) is a ratio that shows the connection between the independent and dependent variables (x and y) (y). If both variables have known values, it may be determined by dividing y by x. The constant of variation is the number that connects two variables that are either directly or inversely proportional to each other.

Answer:
325 adults and 612 students entered the school play
Step-by-step explanation:
1st equation: x is the number of adults and y the number of students.
2nd equation: Students times what they payed + adults times what they payed:
1st: x + y = 937
2nd: 2x + 0.75y = 1109
x = 937 - y
Now let's replace x for (937 - y) in the 2nd equation, to find out the value of y:
2(937 - y) + 0.75y = 1109
1874 - 2y + 0.75y = 1109
1874 - 1.25y = 1109
-1.25y = 1109 - 1874
-1.25y = -765 (multiply -1)
1.25y = 765
y = 765 / 1.25
y = 612
Now that we found the y value, let's replace it in the 1st equation to find out the value of x:
x + 612 = 937
x = 937 - 612
x = 325
If you want to double check it, you can replace both in the 2nd equation, to make sure:
2 * 325 + 0.75 * 612 = 1109
650 + 459 = 1109 (checked)

The total perimeter of fencing that is needed for the entire animal pen is equal to 48 feet.
How to determine the feet of fencing that is needed for the entire animal pen?In order to determine the feet of fencing that is needed for the entire animal pen, we would have to calculate the third side of this right triangle pen by applying Pythagorean's theorem:

c² = 5² +(√11)²
c² = 25 +11 = 36
c = √36 = 6
The length of the third side is 6 units.
What should be taken away from 3x² 4y² 5xy 20 obtain X² y²+ 6xy 20?
The expression that should be subtracted is 4x² - 3y² - xy.
An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.
We will be using the concept of addition and subtraction of algebraic expressions to solve the given question.
Let us assume the missing part is X.
Therefore according to the question,
(3x² - 4y² + 5xy + 20) - (X) = - x² - y² + 6xy + 20
Let us shift the terms to find the value of X
X = 3x² - 4y² + 5xy + 20 - (- x² - y² + 6xy + 20)
X = 3x² - 4y² + 5xy + 20 + x² + y²- 6xy - 20
X = 4x² - 3y² - xy
Thus, the expression that should be subtracted is 4x² - 3y² - xy.

Subtract the algebraic fractions x/2 - x/8
Answer:
The answer would be 3x/8.
Step-by-step explanation:
Both fractions would need to have a common denominator, so you could multiply x/2 by 4 on both the top and bottom to get 4x/8.
You could then subtract both the numerators from each other.
4x-x=x
The denominator will stay the same.
X/8.
