Han's mixture has a higher concentration of orange juice concentrate, it is likely to taste stronger compared to Clare's mixture.

To determine whose orange juice mixture tastes stronger, we can compare the concentration of orange juice in each mixture. The concentration of orange juice can be measured by the ratio of orange juice concentrate to the total liquid volume.

Let's calculate the concentration for each mixture:

For Clare's mixture:

- Water: [tex]\(2\frac{1}{2}\)[/tex] cups

- Orange juice concentrate: [tex]\(\frac{1}{3}\)[/tex] cup

Total liquid volume: [tex]\(2\frac{1}{2} + \frac{1}{3} = \frac{7}{2} + \frac{1}{3} = \frac{21}{6} + \frac{2}{6} = \frac{23}{6}\) cups[/tex]

Concentration of orange juice concentrate in Clare's mixture: [tex]\(\frac{\frac{1}{3}}{\frac{23}{6}} = \frac{1}{3} \times \frac{6}{23} = \frac{2}{23}\) (ratio)[/tex]

For Han's mixture:

- Water: [tex]\(1\frac{2}{3}\)[/tex] cups

- Orange juice concentrate: [tex]\(\frac{1}{4}\)[/tex] cup

Total liquid volume: [tex]\(1\frac{2}{3} + \frac{1}{4} = \frac{5}{3} + \frac{1}{4} = \frac{20}{12} + \frac{3}{12} = \frac{23}{12}\) cups[/tex]

Concentration of orange juice concentrate in Han's mixture: [tex]\(\frac{\frac{1}{4}}{\frac{23}{12}} = \frac{1}{4} \times \frac{12}{23} = \frac{3}{23}\) (ratio)[/tex]

Comparing the concentrations:

- Clare's mixture has a concentration of [tex]\(\frac{2}{23}\)[/tex] orange juice concentrate.

- Han's mixture has a concentration of [tex]\(\frac{3}{23}\)[/tex] orange juice concentrate.

Since Han's mixture has a higher concentration of orange juice concentrate, it is likely to taste stronger compared to Clare's mixture.

The probable question maybe:

Clare mixes 2(1)/(2) cups of water with (1)/(3) cup of orange juice concentrate. Han mixes 1(2)/(3) cups of water with (1)/(4) cup of orange juice concentrate. Whose orange juice mixture tastes stronger? Explain or show your reasoning.

Option a. 11 is the right answer

Step-by-step explanation:

To find the value of a function on particular input, the value is put in the function in place of variable

Given function is:

[tex]f(x) = \left \{ {{3x-7\ \ \ x>0} \atop {2x+3\ \ \  x<0}} \right.[/tex]

As we have to find f(6) and x>0 the part of function 3x-7 will be used

so,

[tex]f(6) = 3(6)-7\\= 18-7\\=11[/tex]

Hence,

Option a. 11 is the right answer

Answer:

25x+300=y

Step-by-step explanation:

The equation represents Tonya's profit, y, for working x for hours is

y = 25x - 300

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Tonya's profit will depend on how many hours she works and how much she earns from tutoring.

Let's assume she works x hours, then she earns 25x dollars from tutoring.

However, she also has to pay the monthly rent of $300 regardless of how many hours she works.

Therefore, her profit y can be calculated as follows:

y = 25x - 300

This equation takes into account both her revenue (25x) and her expenses (the fixed cost of $300 for rent), and gives us her profit as the difference between the two.

Thus,

The equation represents Tonya's profit, y, for working x for hours is

y = 25x - 300

Answer:

Step-by-step explanation:

3 blobs for 1.50

that means 1 blob is (1.50 / 3) which is 50 cents per blob

0.50 * 6 = 3 dollars for 6 blobs

The question is about cost ratios. Given that 3 blobs are worth $1.50, a single blob is worth $0.50. Therefore, 6 blobs would cost $3.00.

The question is asking about cost ratios. In the presented situation, there are 3 blobs for every $1.50. We can say that the cost of one blob is $1.50 divided by 3, which is $0.50. If we are looking for the cost of 6 blobs, we simply multiply the cost of one by 6, which gives us $3.00. Therefore, 6 blobs cost $3.00.

Final answer:

To determine the number of classes at which the total cost for both options is the same, we can set up an equation. When attending 6 classes in a month, the total cost for both options will be the same, which is $60.

Explanation:

To determine the number of classes at which the total cost for both options is the same, we can set up an equation. Let x be the number of classes attended in a month.

For the membership option, the total cost is $60 per month.

For the walk-in option, the total cost is $10 multiplied by the number of classes attended.

Setting up the equation, we have:

60 = 10x

Dividing both sides by 10, we find:

x = 6 classes

So, when attending 6 classes in a month, the total cost for both options will be the same.

Using this value of x, we can find the total amount. For the membership option, it would be $60. For the walk-in option, the total amount is $10 multiplied by 6 classes, which is $60 as well.

Answer:

The area of the rectangular playroom is 260 feet² .

Step-by-step explanation:

Given:

The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.

Now, to find its area we need the length .

So, putting the formula of perimeter we get it's length:

Let the length be l .

Perimeter = 2( length + width)

[tex]72=2(l+10)[/tex]

[tex]72=2l+20[/tex]

subtracting both sides from 20:

[tex]72-20=2l+20-20[/tex]

[tex]52=2l[/tex]

Dividing both sides by 2:

[tex]52\div2=2l\div2[/tex]

[tex]26=l[/tex]

Length is 26 feet.

And, to get the area we put the formula of finding the area:

[tex]Area=length\times width[/tex]

[tex]Area=26\times 10[/tex]

[tex]Area=260[/tex]

Therefore, the area of the rectangular playroom is 260 feet² .

Final answer:

To determine the area of the rectangular playroom at Miss Pittypat's Day Care, we calculate the length using the perimeter and width provided, then multiply the length by the width. The playroom's area is found to be 260 square feet.

Explanation:

The question involves calculating the area of a rectangle when given the perimeter and the width. To find the length, we first use the perimeter formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Since the perimeter is given as 72 feet and the width is 10 feet, we can solve for the length:

72 = 2l + 2(10)

72 = 2l + 20

52 = 2l

l = 26 feet

Once we have the length, we calculate the area by multiplying the length by the width:

Area = l × w

Area = 26 ft × 10 ft

Area = 260 square feet

Therefore, the area of the rectangular playroom is 260 square feet.

Answer:

x=510/7

Step-by-step explanation:

51/70=x/100

cross product

70*x=51*100

70x=5100

x=5100/70

x=510/7

x =72.86. This means that 51 out of 70 is equivalent to 72.86%.

51/70 = x/100.

51 * 100 = 70 * x.

5100 = 70 x

5100 / 70 = x.

The result is x = 72.86.

So, x = 72.86.

This means 51 out of 70 is equivalent to 72.86 out of 100 as a percentage.

[tex]y=0.15x[/tex]

Step-by-step explanation:

Given:

Original price of the ticket is [tex]x[/tex]

Price after using the coupon is [tex]y[/tex]

Coupon discount is 85% of [tex]x=0.85x[/tex]

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

[tex]y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x[/tex]

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line [tex]y=0.15x[/tex] strictly remains in the first quadrant as both [tex]x[/tex] and [tex]y[/tex] can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of [tex]x[/tex] and [tex]y[/tex] positive.

Symmetry is when an image or being is halved into two, and both sides are the exact same to each other.

Final answer:

Symmetry in mathematics refers to an object's balanced or invariant properties under transformations like reflection, rotation, or translation. It is significant in physics for understanding conservation laws and is observed in various aspects of nature and art, providing balance and stability.

Explanation:

Symmetry is a fundamental concept in mathematics, physics, and the natural world. It implies that an object or system possesses a form of invariance or balance under certain transformations, such as reflection, rotation, or translation. In mathematical terms, symmetry refers to a situation where a figure can be manipulated in various ways, such as being flipped over a mirror plane (reflective symmetry), rotated around a central point (rotational symmetry), or shifted along a direction without changing its appearance (translational symmetry).

An example of symmetry in nature is bilateral symmetry, where an object can be divided into two symmetrical parts across a unique plane. This type of symmetry is easily observed in some living organisms, like humans, who have a left and right side that are mirror images of each other. In the realm of physics, symmetry plays an impactful role, especially in the study of sub-atomic particles through the use of particle accelerators like the Large Hadron Collider at CERN. Emmy Noether's work highlighted the deep connection between symmetries and conservation laws, illustrating the significance of symmetry in understanding the foundational principles of our universe.

In art, symmetry is associated with balance and harmony. Symmetrical balance is visually stable, often featuring compositions that are identical, or nearly so, on either side of a central axis. Optical devices, such as mirrors and lenses, also exploit principles of symmetry, with their function heavily dependent on a specific optical axis to guide light appropriately.

Answer:

3.8m+4.25n=23250

Step-by-step explanation:

To express the total sales of gasoline and diesel fuel worth $23,250, the equation is: 3.80m + 4.25n = 23,250, where m is the gallons of gasoline sold and n is the gallons of diesel sold.

The question asks for an equation that represents the total sales of fuel worth $23,250, where m gallons of gasoline are sold at $3.80 per gallon and n gallons of diesel fuel are sold at $4.25 per gallon. To find this equation, we can multiply the number of gallons of each fuel type by its respective price per gallon and set the sum equal to the total sales value.

Therefore, the equation is: 3.80m + 4.25n = 23,250.

This equation signifies that the revenue generated from selling m gallons of gasoline at $3.80 per gallon plus the revenue from selling n gallons of diesel at $4.25 per gallon equals $23,250.

Step-by-step explanation:

The range of function is { 0, -6, -9}

Given that the function is:

[tex]f(x) = \frac{-3}{4}x - 6[/tex]

Also given its domain is (-8, 0, 4)

To find: Range of the function

Domain of the function is possible input of the function that is "x" and range of the function is possible output of the function that is f(x)  

As there are only three input values for "x" that are (-8, 0, 4) we can determine the range by calculating value of f(x) for each of the x

For x = 8:

[tex]f(-8)=\frac{-3}{4} \times(-8)-6=6-6=0[/tex]

[tex]f(-8)=0[/tex]

For x = 0:

[tex]\begin{array}{l}{f(0)=\frac{-3}{4} \times(0)-6=-6} \\\\ {f(0)=-6}\end{array}[/tex]

For x = 4:

[tex]\begin{array}{l}{f(4)=\frac{-3}{4} \times(4)-6=-3-6=-9} \\\\ {f(4)=-9}\end{array}[/tex]

Thus the range of function is { 0, -6, -9}
