Elena can make 20/3 cups of purple paint

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

WE are given that Elena makes her favorite shade of purple paint by mixing 3 cups of blue paint, 1 1/2 cups of red paint, and 1/2 cup of white paint.

Since Elena has 2/3 cup of white paint. then;

1 1/2 cups of red paint (1 1/2=1.5)

1/2 cup of white paint (1/2=0.5)

Then the ratio is 3:1.5:0.5

Means every 0.5 cups of white paint Elena makes 5 cups of purple paint (3+1.5+0.5)

Let x the number of cups of purple paint

5/ 0.5 = x / (2/5)

x = 20/3 cups of purple paint

There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.

To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.

Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:

Total combinations = Number of color options × Number of wheel size options

Total combinations = 4 colors × 2 wheel sizes

Total combinations = 8

The price charged for 630 square feet is $220.5

If a painter can paint 180 square feet per hour, the amount he will paint in 3.5 hours will be 3.5 * 180 = 630 square feet

If the painter charges $0.35 per square foot, the price for 630 square feet will be expressed as 0.35 * 630 = $220.5

Option (D) : (3.5, 8.75)

The perimeter and the area of the rectangle is as follows:

perimeter=182 cm

area=2028cm².

A rectangle is a closed, four-sided figure in two dimensions. The opposite sides of a rectangle are equal and parallel to one another, and all of its angles are 90 degrees.

The area of a rectangle is equal to the product of the rectangle's length and breadth, or "l" and "w," and is written as follows:

Rectangular Area = (l x w)

The formula for the perimeter, 'P' of a rectangle whose length and width are 'l' and 'w' respectively is 2(l + w).

Formula for the Perimeter of a Rectangle: 2 (Length + Width)

Now in the question given,

Length of the rectangle = 8cm.

Width of the rectangle = 6cm.

So, original perimeter=2 × (8+6) +28 cm and

original area=8 × 6= 48 cm²

Now the scale factor = 6.5

New length = 8 × 6.5 = 52cm

width = 6 × 6.5 = 39cm.

New perimeter = 2(52+39) =182 cm.

New area = 52 × 39 = 2028cm².

The completed table of values for the equation 4x + 2y = 64 is provided .

To complete the table of values for the equation 4x + 2y = 64, we can assign different values to x and solve for y. Let's choose a range of values for x and calculate the corresponding values of y.

Table of Values:

8 24

12 20

32 0

To find the values of y, we substitute each x-value into the equation and solve for y. For example, when x is 0, we have 4(0) + 2y = 64, which simplifies to 2y = 64 and y = 32. Similarly, for x = 4, we have \(4(4) + 2y = 64\), which simplifies to \(16 + 2y = 64\) and\(y = 28.\)

a. F is concave up on (-∞, 0) ∪ (6, ∞) and concave down on (0, 6).

b. The inflection points are (0, -2) and (6, -226).

a) To determine the intervals of concavity, we need to find the second derivative of f:

f(x) = (x⁴)/4-3x³-2f'(x) = x³ - 9x²f''(x) = 3x² - 18x

The second derivative f''(x) is a polynomial. We need to find the values of x for which f''(x) is zero or undefined.3x² - 18x = 3x(x - 6)f''(x) = 0 when x = 0 or x = 6.

Now we can determine the intervals of concavity by testing the sign of f''(x) in each interval:

Interval (-∞, 0):f''(-1) = 3(-1)² - 18(-1) = 21 &gt; 0, so f is concave up on (-∞, 0).

Interval (0, 6):f''(1) = 3(1)² - 18(1) = -15 &lt; 0, so f is concave down on (0, 6).

Interval (6, ∞):f''(7) = 3(7)² - 18(7) = 63 &gt; 0, so f is concave up on (6, ∞).

Therefore, f is concave up on (-∞, 0) ∪ (6, ∞) and concave down on (0, 6).

B. The inflection points occur where the concavity changes, which are at x = 0 and x = 6.

The ordered pairs for the inflection points are (0, f(0)) and (6, f(6)).

f(0) = -2 and f(6) = -226, so the inflection points are (0, -2) and (6, -226).

c) To find the critical points, we need to find the values of x for which f'(x) = 0 or f'(x) is undefined:

f'(x) = x³ - 9x² = x²(x - 9)

f'(x) = 0

when x = 0 or x = 9.f''(0) = 0,

so we can use the First Derivative Test to determine that f has a relative maximum at x = 0.f''(9) = 36 &

gt; 0 so we can use the Second Derivative Test to determine that f has a relative minimum at x = 9.

Therefore, the relative extrema are:

Relative maximum at x = 0.

Relative minimum at x = 9.

d) To find where f'(x) has relative maxima and minima, we need to find the values of x for which f''(x) = 0 or f''(x) is undefined:

f''(x) = 3x² - 18x = 3x(x - 6)f''(x) = 0 when x = 0 or x = 6.

We can use the First Derivative Test to determine the nature of the relative extrema:

For x &

lt; 0, f'(x) is negative, then f'(x) is increasing from negative to zero as x approaches 0 from the left.

Therefore, f'(x) has a relative minimum at x = 0.

For 0 &lt; x &lt; 6, f'(x) is positive, then f'(x) is increasing from zero to positive as x increases.

Therefore, f'(x) has a relative maximum at x > 0.

Answer:

A ribeye steak dinner costs $32.23 and a grilled salmon dinner costs $14.04.

Step-by-step explanation:

Let's use variables to represent the cost of each dinner. Let's say that the cost of a ribeye steak dinner is "r" and the cost of a grilled salmon dinner is "s".

From the first day's sales, we know:

From the second day's sales, we know:

We now have two equations with two variables, which we can solve using elimination or substitution.

Let's use elimination. If we multiply the first equation by 15 and the second equation by 11, we can eliminate the "r" variable:

Subtracting the second equation from the first, we get:

Dividing both sides by 133, we get:

So a grilled salmon dinner costs $14.04.

We can substitute this value back into one of the original equations to solve for "r". Let's use the first equation:

So a ribeye steak dinner costs $32.23.

Therefore, a ribeye steak dinner costs $32.23 and a grilled salmon dinner costs $14.04.

Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².

Surface area is the measure of the total area that the surface of a three-dimensional object occupies.

To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:

Surface area = 2(lw + lh + wh)

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

So, if we have a rectangular prism with the following dimensions:

Length (l) = 3.5 inches

Width (w) = 4 inches

Height (h) = 6 inches

The surface area can be calculated as follows:

Surface area = 2(lw + lh + wh)

= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)

= 2(14 + 21 + 24)

= 2(59)

= 118In²

Therefore, the surface area of this rectangular prism is 118 In².
