A container of coffee i 1/6 full. The container contain 2/3 pound of coffee a. Write a diviion expreion that repreent the capacity of the container. B. Write a related multiplication expreion that repreent the capacity of
the container. C. Find the capacity of the container
The division expression that represents the capacity of the container is 2/3 ÷ 1/6, the multiplication expression that represents the capacity of the container is 2 x 6 / 3, the capacity of the container is 4 pound.
An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.
Let us assume total capacity of the container = x pounds.
Container contains 1/6th coffee of total x pounds, that is x/6 pounds.
We also given that 1/6th part is equal to 2/3 of a pound.
So, we could setup an equation now.
x/6 pounds equals 2/3 of a pound.
[tex]\frac{x}{6} = \frac{2}{3}[/tex]
Dividing both sides by 1/6, we get
[tex]\frac{x}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex] = [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{1}{6}[/tex]
Therefore, x = [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{1}{6}[/tex]
for multiplication expression,
x = [tex]\frac{2}{3}[/tex] × 6 { ∵ a ÷ b = a × [tex]\frac{1}{b}[/tex] }
the capacity of the container is,
x = [tex]\frac{2}{3}[/tex] × 6
x = 4 pound.
Therefore, the division expression that represents the capacity of the container is 2/3 ÷ 1/6, the multiplication expression that represents the capacity of the container is 2 x 6 / 3, the capacity of the container is 4 pound.

Which ordered pair i a olution to the ytem of inequalitie?
x y > −2
−x y < 1
The solution to the system of inequalities given by x + y > −2 and −x + y < 1 is the ordered pair that lies under the conditions x > -3/2 and y > -1/2. One of which is (1, 0).
An inequality is a statement about the relative size or order of two values. It's a statement that one value is greater than, less than, greater than or equal to, less than or equal to, or not equal to another value. It's represented using mathematical symbols such as <, >, ≤, ≥, ≠.
To find the solution to a system of inequalities, rewrite any of the two inequalities as y in terms of x.
x + y > -2 can be rewritten as y > -x - 2
Substitute the value of y into the other inequality.
-x + y < 1 will become -x + (-x - 2) < 1
Solve for the value of x.
-x + (-x - 2) < 1
-2x -2 < 1
-2x < 1 + 2
-2x < 3
2x > -3
x > -3/2
Plug in the value of x into the equation of y and solve for y.
y > -x - 2
y > -(-3/2) - 2
y > -1/2
So, the solution of the system of inequalities will be the region where both of these conditions, x > -3/2 and y > -1/2, are true, which is the area where the graph of y > -x - 2 and y < x + 1 overlap.
One ordered pair (1 , 0) is a solution to the system of inequalities x + y > -2 and -x + y < 1.
We can check it by plugging in the ordered pair into the inequalities.
x + y > -2 becomes 1 + 0 > -2 which is true
-x + y < 1 becomes -1 + 0 < 1 which is true
So (1,0) satisfies both inequalities.

Answer:
y = 7x + 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = 7 , then
y = 7x + b ← is the partial equation
to find b substitute (1, 8 ) into the partial equation
8 = 7(1) + b = 7 + b ( subtract 7 from both sides )
1 = b
y = 7x + 1 ← equation of line
find the gcf of each
Write down the set of numbers for which you want to find the GCF.
Starting from 1, check if each number in the set is divisible by it. If all the numbers are divisible by it, mark it as a common factor.
Repeat step 2, incrementing the number by 1, until you reach the smallest number in the set.
The largest common factor that you marked in step 2 is the GCF.
This method is based on the idea of checking each number starting from 1 till the smallest number in the set and checking if it is divisible by all numbers in the set. It's a simple method that can be applied to find GCF of any set of numbers.
It's worth noting that this method may not be the most efficient way to find GCF of set of numbers, as it involves checking each number starting from 1 till the smallest number in the set. In cases where the numbers are large, more efficient methods like prime factorization and Euclidean algorithm are preferred.
Why can't the denominator of a fraction be negative?
When you divide a fraction by a negative number, it doesn't matter what happens to the denominator because the entire result, or quotient, is the reverse of whatever the original fraction was.
What is the denominator?In mathematics, a denominator is the lowest number in a fraction that indicates how many equal parts are divided into a whole.
It is a fraction's divisor. In this case, the denominator is 4, thus there are four components overall.
The top number in a fraction is referred to as the numerator, while the bottom number is referred to as the denominator.
4/5, for instance, is a fraction.
What happens to the denominator of a fraction when you divide it by a negative number is unimportant because the entire result, or quotient, is the opposite of whatever the original fraction was.

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal. Consider the equation 3x + 5 = 14, where 3x + 5 and 14 are two expressions that are separated by the symbol "equal."
The smallest equivalent fraction of the number is the form that is the simplest. How to find the most basic form: In the numerator and denominator, look for shared factors. Examine the fraction to see if one of the numbers is a prime number.
Say w= the amount of water in oz, then the 60% of the solution is 250 - w
Set up the equation:
Use distributive property first
0.60(250-w) = 0.15 x 250
Isolate to solve for w
150- 0.60w= 37.5
-0.60w= 37.5-150
0.60w= -112.5
w= 187.5 ounces

Challenge The price of Stock A at 9 A.M. was $13.45. Since then, the price has been increasing at the rate of $0.08 each hour. At noon the price of Stock B was $14.20. It begins to decrease at the rate
of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
In about hours, the prices of the two stocks will be the same.
(Round to the nearest tenth as needed.)
Answer:
Approximately 2.3 hours after 12 noon
Step-by-step explanation:
We are given
Stock A price at 9AM = $13.45
It increases by $0.08 per hour
Stock B at noon = $14.20
It decreases by $0.14 each hour
We have to find when the two prices will be the same.
Since the base time references are different - 9am for A and noon for B, we have to establish the same time reference
Let's do this by finding the price of stock A at noon, then we have the same time base reference of noon
9am - noon = 3 hours
In 3 hours stock A would have risen by 0.08 x 3 = $0.24
Price of stock A at noon is 13.45 + 0.24 = $13.69
Thereafter stock A continues to increase by the same rate of $0.08 per hour
The equation to model stock A price starting at noon is
13.69 + 0.08x where x is the number of hours elapsed after 12 noon
Stock B price is $14.20 at 12 noon and decreases by $0.14 per hour
Equation to model stock B price after 12 noon is
14.20 - 0.14x where x is the elapsed time after 12 noon
For both prices to be the same after the same x hours, we have
13.69 + 0.08x = 14.20 - 0.14x
Solving for x will tell us how many hours it will take for both stock prices to be the same
Solving
13.69 + 0.08x = 14.20 - 0.14x
So the two stock prices will be the same 2.3 hours after 12 noon or about 2 hours and 18 minutes after 12 noon or roughly around 2:18pm
I got 18 minutes by multiplying 0.3 x 60 = 18
Is F G x )) the inverse of g/f x ))?.
No, "FG)(x)" and "g/f)(x)" are not inverse of each other."FG)(x)" refers to the composition of two functions, "F" and "G", where the output of "G" is used as the input for "F".
The notation for this is represented as "F(G(x))", where "x" is the input for both functions.
The function "F" is applied to the output of the function "G", meaning that the output of the function "G" is used as the input for the function "F".
On the other hand, "g/f)(x)" is not a standard notation in mathematics. It could be interpreted as applying the function "g" to the input "x", and then applying the function "f" to the result of "g". But it could also be interpreted as applying f to the input x and then applying g to the result of f.
Inverse functions are related to the idea of reversing the effect of a function. For example, if "f" is a function that maps a set of inputs to a set of outputs, then the inverse function "f^-1" maps the set of outputs back to the original set of inputs. The notation for an inverse function is typically represented as "f^-1(x)" or "f^(-1)(x)". It's important to note that not all functions have inverses, and the inverse of a function is also a function.

When two variables are related in a way where their product is always constant, that relationship is called an inverse proportion. Y = k/x or xy = k, where k is a constant, are two ways to express it mathematically. Hyperbolas which are curved graphs are formed with inverse proportions. Collecting all points in the plane where the gap between two fixed points and a fixed point is constant is known as a hyperbola.
With the foci on the y-axis and the x-axis serving as the hyperbola's centre, the graph of the equation y = k/x is a hyperbola. The y-axis serves as the hyperbola's centre of gravity, with the x-axis serving as its foci, on the graph of the equation xy = k.

The total discount tickets sold are 8460 tickets.
A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product. It is mostly used in consumer transactions, where people are provided with discounts on various products. The discount rate is given in percentage.
We have that,
94% = 94/100
= 0.94
By multiplying the tickets sold by the factor of 0.94, we get
