Final answer:

Mindy bought 10 grapefruits at a rate of $6.00 per dozen. By calculating the cost per grapefruit at 50 cents and multiplying by 10, we find that she paid a total of $5.00 for the grapefruits.

Explanation:

Calculating the Cost of Grapefruits

Mindy bought 10 grapefruits at the rate of $6.00 per dozen. To find out how much she paid for the grapefruits, we need to calculate the cost per grapefruit and then multiply by the number she bought.

A dozen grapefruits cost $6.00, so each grapefruit costs $6.00 divided by 12, which is 50 cents per grapefruit. Since Mindy bought 10 grapefruits, the total cost will be 10 grapefruits multiplied by 50 cents each.

Performing the multiplication, we get:

10 grapefruits × 50 cents per grapefruit = 500 cents

Since there are 100 cents in a dollar, 500 cents is the same as $5.00.

Therefore, Mindy paid $5.00 for the grapefruits.

Answer:

36 = (w+5)w = w^2 + 5w

Step-by-step explanation:

The equation to find the dimensions of the window is w*(w + 5) = 36, where w represents the width of the window.

The subject of this question is Mathematics. This problem is a classic example of a quadratic equation in algebra, where you are given the area of a rectangle and a relationship between its length and width. In this case, the length of the rectangle is 5 feet more than its width (w). So, the length can be represented as w + 5. The area of a rectangle is calculated as length times width, so we can set up the following equation where the area is 36 square feet: w*(w + 5) = 36.

Mafalda's save percentage improved by 0.153.

Solution:

Given that, Mafalda has a save percentage of 0.7380 so far this hockey season

Last season, her save percentage was 0.5850

To find: Percentage improved

To find improvement in Mafalda's save percentage we will subtract last season's save percentage from this season's save percentage.

From given,

Last season save percentage = 0.5850

This season save percentage = 0.7380

Percentage improved = This season save percentage - Last season save percentage

[tex]Percentage\ Improved = 0.7380-0.5850\\\\Percentage\ Improved =0.153[/tex]

Thus Mafalda's save percentage improved by 0.153.

Answer:

The potential energy of the ball having 2kg mass would be [tex]392[/tex] J

Step-by-step explanation:

I am assuming the ball has a mass of 2 kg, as you have not mentioned the mass of a ball.

Considering the formula for calculating the gravitational potential energy

Sharif : Jose ---> 2:7

this means that:

Fraction of total that Sharif gets = 2 / (2+7) = 2/9

Fraction of total that Jose gets = 7 / (2+7) = 7/9

we are given that Jose gets $49, hence

jose's fraction = 7/9 ,  represents $49

Answer:

A) The teacher brought 384 fluid ounces of juice

B)NO, the teacher doesn't have enough juice to give each student a 12-fluid ounce glass of juice

Step-by-step explanation:

Given:

The total quantity of juice brought by the teacher for the field trip = 3 gallons of juice

The number of students in the field trip =  36

A)fluid ounces of juice

We know that

1 gallon  = 128 fluid ounce

So we have to convert the given 3 gallons of juice to fluid ounces

3 gallons of fruit juice [tex]= 3 \times 128[/tex] fluid ounces

3 gallons of fruit juice  =  384 fluid ounces

The teacher had 384 fluid ounces of fruit juice

B. enough juice to give each student a 12-fluid ounce glass of juice

The teacher wants to give 12 fluid ounce of juice to one student

So, to give 36 students

the teacher will need

=> [tex]36 \times 12[/tex]

=> 432 fluid ounces of juice

but the teacher has only 384 fluid ounces of juice .

Thus the teacher still  needs 48 fluid ounces of juice

The taxes and profits total $1000.

Question asked:

Amount of taxes = ?

Solution:

Let ratios = [tex]x[/tex]

Without a clear graph or a well-defined inequality, it is not possible to determine which inequality is graphed. An inequality and its graph on the coordinate plane represent solutions to the inequality, such as regions to the right of a vertical line for x > 2.

The student has asked which inequality is graphed. Unfortunately, the provided information is insufficient to determine the inequality or the graph in question. Moreover, the data given appears to be disorganized or incorrectly transcribed, making it impossible to provide a specific answer. For a proper response, one would need either a clear description of the graph or the correct functional form of the inequality.

To demonstrate inequalities and their graphs, one might typically use coordinate axes where solutions to the inequality are represented by regions of the plane. For example, the inequality x > 2 would be represented graphically by a shaded region to the right of the line x = 2 on a number line, or in two dimensions, to the right of the vertical line x = 2.

If the student can provide a clear and accurate description of the graph or the inequality they are inquiring about, a more precise answer could be given.

Find the average rate of change of f(x) = 3(2)^x between x = 1 and x = 4

The average rate of change is 14

The rate of change is given by formula:

[tex]\text { Average Rate }=\frac{f(b)-f(a)}{b-a}[/tex]

Here the given interval is x = 1 and x = 4

Therefore, the formula becomes,

[tex]\text { Average Rate }=\frac{f(4)-f(1)}{4-1}\\\\\text { Average Rate }=\frac{f(4)-f(1)}{3}[/tex]

Let us find f(4) and f(1)

Given function is:

[tex]f(x)=3(2)^x[/tex]

Substitute x = 4 in function

[tex]f(4)=3(2)^4\\\\f(4) = 3 \times 16 = 48[/tex]

Thus f(4) = 48

Substitute x = 1 in function

[tex]f(1) = 3(2)^1\\\\f(1) = 6[/tex]

Now substitute the values back into formula

[tex]\text { Average Rate }=\frac{f(4)-f(1)}{3}\\\\\text { Average Rate }= \frac{48-6}{3}\\\\\text { Average Rate }= 14[/tex]

Thus average rate of change is 14

Answer:

13.3

Step-by-step explanation:

Because in order to get the a separated from the 0.9, you must divide the 0.9a by 0.9 to cancel the 0.9 out of the equation. That way, you are left with A. but in order to do that, you must divide both sides of the equation.

Ultimately, it ends up being 12 divided by 0.9, which is 13.3

To find the cost of renting a canoe for 7 hours, we can set up a linear equation using the given information. Using the point-slope form, we can find the equation of the line. Substituting x = 7 into the equation gives us the cost for 7 hours. The cost of renting a canoe for 7 hours is $100.25.

To find the cost of renting a canoe for 7 hours, we can set up a linear equation using the given information. Let's define the variables:

x = number of hours

y = cost of renting a canoe for x hours

From the given information, we know that it cost $12 per hour to rent a canoe. Nate and his friends rented a canoe for 4 hours and paid $68. This gives us the first point on the line: (4, 68).

To find the equation, we can use the point-slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Using the slope formula, we can find the slope: m = (y2 - y1) / (x2 - x1) = (68 - 25) / (4 - 0) = 43 / 4 = 10.75.

Now we can plug in the values into the point-slope form: y - 68 = 10.75(x - 4).

To find the cost for 7 hours, we substitute x = 7 into the equation and solve for y: y - 68 = 10.75(7 - 4), y - 68 = 10.75 * 3, y - 68 = 32.25, y = 32.25 + 68, y = 100.25.

Therefore, the cost of renting a canoe for 7 hours is $100.25.

Final answer:

To calculate the cost of renting a canoe for 7 hours, first find the fixed cost by using the known rental time and cost. The equation is y = 12x + 20, where y is the total cost and x is the number of hours. For 7 hours, the cost is $104.

Explanation:

We are given that the cost to rent a canoe at Eagle Bay is $12 per hour. Nate and his friends rented the canoe for 4 hours, and they paid a total of $68. To find the equation, we need to consider that there might be a fixed cost in addition to the hourly charge. First, let's define our variables: let x be the number of hours the canoe is rented, and let y be the total cost.

Based on the information provided, we can create the equation y = 12x + b, where b is the possible fixed cost.

To find the fixed cost, we use the information that renting the canoe for 4 hours cost $68: 68 = 12(4) + b. Solving for b, we find:

68 = 48 + b
b = 68 - 48
b = 20

So, the fixed cost is $20, and the equation becomes y = 12x + 20. To find the cost of renting the canoe for 7 hours, we substitute 7 for x in our equation:

y = 12(7) + 20
y = 84 + 20
y = $104

The cost to rent the canoe for 7 hours would be $104.

Answer:

C. The difference of the medians is 4 times the interquartile range.

Step-by-step explanation:

The diagram show two box plots.

Mahoney's box plot:

Median [tex]=33[/tex]

Interquartile range [tex]=34-32=2[/tex]

Martin's box plot:

Median [tex]=41[/tex]

Interquartile range [tex]=42-40=2[/tex]

The interquartile ranges are the  same.

The difference of the medians [tex]=41-33=8[/tex]

Hence, the difference of the medians is 4 times the interquartile range.

There is no standard relationship stating that the difference of medians is a certain multiple of the interquartile range. The median and interquartile range measure different aspects of a dataset (central tendency and dispersion, respectively), so comparing them in this way is not universally applicable.

The question is asking about a theoretical relationship between the median and the interquartile range (IQR) in a set of data. However, in statistics, there's no standard relationship that states the difference of medians is a certain multiple of the interquartile range. The median is a measure of central tendency, or a 'middle' value of a dataset, while the interquartile range is a measure of dispersion, indicating the variability within the data. The difference between two medians or the comparison of a median to the interquartile range would be specific to a certain dataset, and it's not a universal relationship.

Answer:

x = 3

Step-by-step explanation:

We should know that:

A straight segment joining the middle of two sides in a triangle is parallel to the third side and equal to half of it.

So,

3x + 1 = (1/2) * 20 = 10

3x = 10 - 1 = 9

x = 9/3 = 3

So, the value of x = 3

Answer:

Infinitely many solution.

Step-by-step explanation:

The given system is

x = y + 4

y = x - 4

To graph the first equation, we write it in slope-intercept form to get: to

x=y+4

This implies y=x-4.

This has a slope of 1 and a y-intercept of -4.

The graph of this function is shown in the attachment.

The second equation is y=x-4.

This equation is identical to first equation, so its graph coincides with the first one.

The system has infinitely many solution.

The system of equations has infinitely many solutions.

The system of equations:

1. [tex]\( x = y + 4 \)[/tex]

2. [tex]\( y = x - 4 \)[/tex]

can be rearranged to show that they represent the same line:

1. [tex]\( y = x - 4 \)[/tex] (Rearranged from [tex]\( x = y + 4 \)[/tex])

2. [tex]\( y = x - 4 \)[/tex]

Graphing these equations shows that they are the same line, meaning every point on the line [tex]\( y = x - 4 \)[/tex] is a solution to the system.

Thus, the solution to the system of equations is all points [tex]\((x, y)\)[/tex] that satisfy [tex]\( y = x - 4 \)[/tex]. This means the lines intersect everywhere along [tex]\( y = x - 4 \)[/tex].

There is no single intersection point because they overlap completely.

Answer:

Step-by-step explanation:

In general, the point of an inverse function is to show you the value that gives a particular function value. That is, ...

  [tex]f^{-1}(22)=7\\\\f^{-1}(f(x))=x\\\\f^{-1}(f(7))=7[/tex]

The inverse function  [tex]f^{-1}[/tex]essentially 'undoes' the operation of the function f. Given that f(7) is 22, applying the inverse function [tex]f^{-1}(f(7))[/tex] will return us to the original input, which is 7.

The question is discussing the concept of inverse functions in mathematics. A function has an inverse if it can be 'undone' or 'reversed'. In the notation  [tex]f^{-1}[/tex], it signifies the inverse function of f. The value of [tex]f^{-1}(f(7))[/tex] indicates that we have first applied the function f to the input 7 and then applied the inverse function [tex]f^{-1}[/tex] The result would be the original input before function f was applied.

Given that f(7) is equal to 22, applying the inverse function f^-1 to this result will return us to the original input. Hence, [tex]f^{-1}(f(7))[/tex]equals 7.

If one-third of a number, x, is greater than five less than twice the number, which of the following is true?​ x < 3, x > -3, x > -3/5, x < 3/5

Option A

The true inequality is x < 3

Let the number be "x"

One third of number means that,

[tex]\rightarrow \frac{1}{3} \text{ of number } = \frac{1}{3} \times x = \frac{x}{3}[/tex]

Thus from given statement,

one-third of a number x is greater than five less than twice the number

[tex]\text{ one-third of a number x } > \text{ five less than twice the number x }[/tex]

[tex]\frac{x}{3} > 2x - 5[/tex]

Solve the above inequality

Multiply both sides of inequality by 3

[tex]\frac{x}{3} \times 3 > (2x - 5) \times 3[/tex]

[tex]x > 3(2x-5)[/tex]

Solve for brackets in R.H.S

[tex]x > 6x - 15[/tex]

Add -6x on both sides of inequality

[tex]x - 6x > 6x - 15 -6x\\\\-5x>-15[/tex]

Multiply both sides of inequality by -1

Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign

[tex]5x < 15[/tex]

Divide both sides of inequality by 5

[tex]x < 3[/tex]

Thus the true inequality is x < 3

Final answer:

The inequality one-third of a number x being greater than five less than twice the number translates to x < 3 after solving the inequality properly.

Explanation:

If one-third of a number, x, is greater than five less than twice the number, we can write this as an inequality. To solve for x, we can set up the following expression:

Now, we need to solve for x. First, we'll get all the x terms on one side and the constants on the other:

The statement that is true is that x is less than 3. This means all solutions for x are numbers that are less than 3.
