The expression that represents the situation is (5/2)x = y and the family uses 350 gallons of water for each week.

First, we convert the given fractions into improper fractions as follows;

2 1/2 = 5/2

2 1/3 = 7/3

As the showerhead uses 5/2 gallons of water per minute an expression for this situation can be given as;

(5/2)x = y

Here x is the amount of time in minutes and y represents the gallons of water used by the family each week

As the family uses the showerhead for 7/3 hours per week, we first convert the hours into minutes as follows;

(7/3) × 60 = 140 minutes

Now substituting this value in the equation (5/2)x = y;

(5/2)x = y

(5/2)140 = y

y = 350 gallons

Therefore, 350 gallons of water is used by the family per week.

Step-by-step explanation:

All decimals which either terminate or have a repeating pattern after some point are also rational numbers. The number 0.2 is a rational number because it can be re-written as 1/5 . The number 0. 33333… is a rational number because it can be re-written as 1/3 .

The LCM of both the factors x⁴+x³-x²-x, x⁴-x and 4x²-4 is discovered to be x(x+1)²(x-1).

The LCM of any two numbers is the value that is evenly divisible by the two given numbers. Least Common Multiple is an abbreviation for Least Common Multiples. It's also known as the Least Common Divisor (LCD).

The smallest integer that is a multiple of two or more numbers is known as the LCM. For instance, the LCM of 4 and 6 is 12, and the LCM of 10 and 15 is 30.

The two given expressions are:

x⁴+x³-x²-x, x⁴-x and 4x²-4

Let us simplify both these factors.

x⁴+x³-x²-x = x(x³ + x² -x -1)

                = x(x+1)(x+1)(x-1)

                = x(x+1)²(x-1)

4x²- 4 = 2²(x+1)(x-1)

Multiplying each factor with the highest power,

4x²- 4  = 2²x(x+1)²(x-1)

           = 4x(x+1)²(x-1)

Thus x(x+1)²(x-1) is the least common factor of both factors.

As a result, it is discovered that the LCM of  x⁴+x³-x²-x, x⁴-x and 4x²-4. is x(x+1)²(x-1).

Step-by-step explanation:

To make a mixed number from an improper fraction, divide the numerator by the denominator then there exists eight twelfths in two-thirds.

Multiply the full number by the denominator to convert a mixed number to an improper fraction. Include it in the numerator. Add that total to the denominator from the beginning.

To make a mixed number from an improper fraction, divide the numerator by the denominator. After division, the mixed number is produced in such a way that the obtained quotient becomes the entire number, the remainder becomes the new numerator, and the denominator remains constant.

Let the value be [tex]$3 \frac{2}{3}$[/tex].

Convert mixed numbers to improper fraction:

[tex]$a \frac{b}{c}=\frac{a \cdot c+b}{c}$[/tex]

substitute the values in the above equation, we get

According to this, the answer is that the employee must sell $32,000 in one month to earn a total of $4,000 for the month.

From the information given, the equation would indicate that the total salary is equal to the base salary plus the result of subtracting $7,000 from the amount of sales for 8%:

2000+(x-7,000)*0.08=4,000, where x is the amount of sales

Now, you can solve for x:

2,000+0.08x-560=4,000

0.08x+1440=4,000

0.08x=4,000- 1440

x=2,560/0.08

x=32,000

According to this, the answer is that the employee must sell $32,000 in one month to earn a total of $4,000 for the month.

The area of the rectangle is increasing at a rate of 122cm²/s if the length of the rectangle is 11 cm and the width is 9 cm.

The area of a rectangle can be described as the product of the length and width of that rectangle, therefore;

Area = L × W

Here L represents length and W represents the width

Now by differentiating using the product rule;

dA/dt = (dL/dt)(W) + (dW/dt)(L)

As the length is 11 cm and the width is 9 cm and the length is increasing at a rate of 5 cm/s and its width is increasing at a rate of 7 cm/s; substituting these values in the equation;

dA/dt = (5)(9) + (7)(11)

dA/dt = 45 + 77

dA/dt = 122

Hence,  the area of the rectangle is increasing at the rate of 122cm²/s.

Let the assumed amount with him be $40.

It should be noted that for David's orchard, the first ten pounds are $2 per round and each additional round is $1 per pound.

Therefore, the expression to illustrate this will be:

($2 × 10) + ($1 × r)

where r = additional pounds

Therefore,

($2 × 10) + ($1 × r) = $40

Step-by-step explanation: because the do things together

Answer:

y = -2x - 4

Step-by-step explanation:

First, substitute the known values into the slope-intercept form, y = mx + b, where m represents the slope of the line and b represents the y-coordinate of the point of intersection of the line and the y-intercept. We are given that the graph has a y-intercept of -4, so substitute -4 for b. The graph contains the point (-6, 8), so substitute -6 for x and 8 for y.

8 = -6m - 4

12 = -6m

m = -2

Finally, substitute -2 for m and -4 for b to write the equation of the line in the form, y = mx + b.

y = -2x - 4

The width of the rectangle with area 70y⁸+ 30y⁶ is; 10y⁶.

Then the length of the rectangle with area 70y⁸+ 30y⁶ is; (7y² + 3).

The area of a rectangle is given by;

Area = Length× width

Given that;

The area of the rectangle = 70y⁸ + 30y⁶

Now, 70y⁸ can be broken down to; 7×5×2×y×y×y×y×y×y×y×y

And 30y⁶ can be broken down to; 5×3×2×y×y×y×y×y×y

The common factors of 70y⁸ and 30y⁶ are = 5,2,y,y,y,y,y,y

Thus, the greatest common factor of 70y⁸ and 30y⁶ is;

5×2×y×y×y×y×y×y = 10y⁶

Therefore our area 70y⁸+ 30y⁶ can be factorized to get;

A = 10y⁶(7y² + 3)

The greatest common monomial of 70y⁸+ 30y⁶ is 10y⁶ which is the width of the rectangle.

The point (1, 18), in the proportional relationship, means 18 cookies will require 1 cup of flour.

In a proportional relationship graph that models the relationship between two variables, x and y, a point on the graph means the value of x that will give a corresponding value of y. It is expressed as, (x, y).

(x, y) means the quantity of x that will give a corresponding quantity of y considering the proportional relationship between variables x and y.

Thus, the graph shows a proportional relationship between the number of cups of flour (y) that was used to make different numbers of cookies.

Thus, the point (1, 18) means that for 18 cookies to be made, 1 cup of flour is to be used.

Step-by-step explanation:

These models are best figured out using regression analysis which is a rather complicated computation but luckily there are calculators that can solve

1. The best way to approach this problem is to plot the values and see whether the model is a linear equation or a higher degree equation.

For all three cases it appears that the equations are not linear which would have suggested a model of the form y = mx + b where y = profit in $, x = hours, m is the slope (rate of increase in profit) and b a constant, the y-intercept

For example if you look at the data for the dog walker table, the increase in $ for every additional hour of service is not constant eliminating a linear model. For the first hour, the increase is $7, the second hour it is $11, the third it is $27

So i assumed a quadratic model of the form y = ax² + bx + c where y = profit in $ and x is the number of hours of service for all three businesses

There are plenty of online calculators out there which can rapidly compute the quadratic regression model parameters fitting the data and provide a level of goodness of fit of the equation through a statistic known as the correlation coefficient, r

I entered the data for all 3 rows and came up with the following results
