Answer:

Price of roses is proportional to the number of roses.

Step-by-step explanation:

Let the price of roses are proportional to the number of roses.

Equation representing this phenomenon will be,

P = k(R) ⇒ k = \(\frac{P}{R}\)

where 'P' = price of the roses

R = Number of roses

k = Proportionality constant

If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.

For R = 3 and P = $9  

k = \(\frac{9}{3}\)

k = 3

For R = 6 and R = 18

k = \(\frac{18}{6}\)

k = 3

K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.

The total weight of the liquid in the tank is approximately 12,628 pounds.

To calculate the weight of the liquid, we need to determine the volume of the hemisphere and then multiply it by the density of the liquid. The formula for the volume of a hemisphere is V = (2/3)πr³, where r is the radius of the hemisphere.

In this case, the diameter of the tank is given as 24 feet, so the radius is half of that, which is 12 feet. Plugging this value into the formula, we get V = (2/3)π(12)³ ≈ 904.78 cubic feet.

Finally, we multiply the volume by the density of the liquid: 904.78 cubic feet * 92.5 pounds per cubic foot ≈ 12,628 pounds. Therefore, the total weight of the liquid in the tank is approximately 12,628 pounds.

In summary, to calculate the weight of the liquid in the tank, we first determine the volume of the hemisphere using the formula V = (2/3)πr³. Then, we multiply the volume by the density of the liquid.

By substituting the given diameter of 24 feet and using the appropriate conversions, we find that the total weight of the liquid is approximately 12,628 pounds.

I'll be referring to each of these numbers as x and y.

x + y = 4

(x^2) + (y^2) - 3(x)(y) = 76

x = 4 - y

(4 - y)^2 + (y^2) - 3(4 - y)(y) = 76

(4 - y)(4 - y) + y^2 - (3y)(4 - y) = 76

16 - 4y - 4y + y^2 + y^2 - 12y + 3y^2 = 76

16 - 20y + 5y^2 = 76

5y^2 - 20y - 60 = 0

y^2 - 4y - 12y = 0

(y - 6)(y + 2) = 0

y = 6 or -2

x = 4 - 6 = -2

x = 4 - - 2 = 6

As you can see, we got the same numbers for both x and y, -2 and 6. Therefore, the two numbers are -2 and 6. But, we can check our work to ensure that the answer is correct.

x = -2

y = 6

6 - 2 = 4

4 = 4

(-2)^2 + (6^2) - 3(-2)(6) = 76

4 + 36 - 3(-12) = 76

40 + 36 = 76

76 = 76

The correct answers are 1st and 4th i.e translate 2 units down and reflect the triangle.

We can easily deduce that the triangle A'B'C' is 2 units higher than the triangle ABC so if we want to map the both the triangles we have to make the triangle A'B'C' lower in the graph.

So, both the 1st and 4th points translate and reflect down the triangle A'B'C'  which will be mapped according to the triangle ABC.

B. The company from which the family should rent the truck is: Company Y.

There are two costs in the problem, given as follows:

The fixed costs for Company X are given as follows:

The variable cost is of 0.59 per mile, hence the function, considering a trip of m miles, is given as follows:

X(m) = 59.90 + 150 + 36 + 0.59m.

X(m) = 245.9 + 0.59m.

The fixed costs for Company Y are given as follows:

The variable cost is of 0.79 per mile, hence the function, considering a trip of m miles, is given as follows:

Y(m) = 39.90 + 52 + 0.79m

Y(m) = 91.9 + 0.79m.

The trip is of 750 miles, hence the costs are given as follows:

Answer:

To graph the equation y=-x^2+12x-35, we need to find the vertex and the roots of the equation.

The equation can be written in vertex form as y=-(x-6)^2+1, where the vertex is (6,1).

To find the roots, we need to set y=0 and solve for x:

0=-x^2+12x-35

x^2-12x+35=0

(x-5)(x-7)=0

x=5 or x=7

So the roots are (5,0) and (7,0).

The vertex is at (6,1) and the roots are at (5,0) and (7,0). The curve is a downward-facing parabola.

==========================================================

Explanation:

There are 12 choices for the first topping and 11 for the next topping. The decrease is to account for the fact we cannot select a repeat topping.

That gives 12*11 = 132 permutations. If order of toppings mattered, then this would be our final answer.

However, the topping order doesn't matter. So we need to divide by 2 to correct for the double counting.

There are 132/2 = 66 combinations.

------------

Alternative Method:

n = 12 toppings are available and r = 2 selections are allowed

Order doesn't matter so we use the nCr combination formula

\(n C r = \frac{n!}{r!(n-r)!}\\\\12 C 2 = \frac{12!}{2!*(12-2)!}\\\\12 C 2 = \frac{12!}{2!*10!}\\\\12 C 2 = \frac{12*11*10!}{2!*10!}\\\\ 12 C 2 = \frac{12*11}{2!}\\\\ 12 C 2 = \frac{12*11}{2*1}\\\\ 12 C 2 = \frac{132}{2}\\\\ 12 C 2 = 66\\\\\)

There are 66 combinations

Notice the 2nd to last step involves 132/2 which was mentioned in the previous section.

Alaska occupies 17.22% of the surface area of the United States. Rounding to the nearest whole number, we get 17%. Hence, the answer is:17%

We are given that the surface area of the United States is 3.797 million square miles and the state of Alaska occupies 655,400 square miles. We need to determine what percentage of the surface area of the United States is occupied by Alaska using ratios.To find the percentage, we need to first find the ratio of Alaska's surface area to the surface area of the United States. We can do this by dividing the surface area of Alaska by the surface area of the United States. That is,655,400 / 3,797,000 = 0.1722We can express this ratio as a percentage by multiplying by 100.

If Joanie is organizing her closet. She has 3 times as many black shirts as gray shirts, plus 3 new black shirts she just bought. The number of gray shirts that Joanie have is: 2.

Let x represent the number of gray shirts

Let Joanie black shirts = 3x + 3

Let Joanie white shirts =  5x - 1

Let Joanie brown shirts =   2x

So,

3x + 3 = 5x - 1

Substract 3 from both side

3x + 3-3 = 5x - 1 -3

3x = 5x -4

Substract 5x from both side

3x-5x = 5x -4 -5x

-2x =  -4

3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.

To express 3 1/2 cups as a multiplication expression using the unit "1 cup" as a factor, you can write it as:

3 1/2 cups = (3 + 1/2) cups = 3 cups + 1/2 cup

Since there are 1 cup in each term, we can rewrite it as:

3 cups + (1/2) cup

Now, we can express each term as a multiplication expression:

3 cups = 3 * 1 cup = 3

(1/2) cup = (1/2) * 1 cup = 1/2

Putting it all together, the multiplication expression is:

3 * 1 cup + (1/2) * 1 cup = 3 + 1/2

Therefore, 3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.
