Elena can make 20/3 cups of purple paint
What is the unitary method?
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

The value of c is a real solution to the equation [tex]4x^{2}-8x +c[/tex] = 0 is 4
What are Real mathematical solutions ?In algebra, a "real solution" is any answer to an equation that is a real number.
There is just one true solution where discriminant b2 - 4ac equals zero. The equation x2 + 2x + 1 = 0 has one solution, x = -1.
Depending on whether the discriminant is positive, zero, or negative, there are many answers to the quadratic equation that has been presented.
A positive discriminant indicates that the quadratic has two distinct real number solutions.
A discriminant of zero indicates that the quadratic equation has a repeating real number solution.
The quadratic equation given is
[tex]4x^{2}-8x +c[/tex] = 0
For real solution
Discriminant = 0
[tex]b^{2}-4ac[/tex] = 0
[tex]8^{2}-4(4)(c)[/tex] = 0
64 - 16c = 0
-16c = -64

Answer:
x < 4 or 6 < x
Step-by-step explanation:
You want the compound inequality that describes the number line graph with open circles at 4 and 6, and shading everywhere except between them.
InequalitiesThe left line segment has all values less than 4 shaded. The corresponding inequality is ...
x < 4
The right line segment has all values greater than 6 shaded. The corresponding inequality is ...
x > 6
These do no overlap, so the compound inequality uses "or" to combine them:
x < 4 or x > 6
__
Additional comment
Sometimes it is helpful to have the relationship between the shading and the limit values a little more obvious in the inequality. That will be the case if you always use left-pointing inequality symbols: < or ≤. By writing the compound inequality as ...
x < 4 or 6 < x
we see that shading is outside (left or right of) the interval [4, 6].
The symbol without the "or equal to" bar is used when the circle is an open circle. A filled dot would signify the limit value is part of the interval of interest, and the ≤ (or ≥) symbol would be used.
5. The dimensions of a sandbox can be represented as (x+2) inches and (x+1) inches. The value of the area, in square inches, of the sandbox is equal to the value the perimeter in inches. Write an equation that can be used to find the value of x.
x² - x - 4 = 0 is the equation that can be used to find the value of x.
Given,
The dimensions of a sand box is given as (x + 2) inches and (x + 1) inches.
The value of the area, in square inches, of the sandbox is equal to the value the perimeter in inches.
We have to find an equation that can be used to find the value of x;
Here,
Consider the sand box as a rectangle.
Area of rectangle = length x width
That is,
Area of sand box = (x + 2) (x + 1) = x² + x + 2x + 2 = x² + 3x + 2
Now, Perimeter of rectangle = 2(length + width)
That is,
Perimeter of sand box = 2(x + 2 + x + 1) = 2(2x + 3) = 4x + 6
Now,
Equate both the equations;
x² + 3x + 2 = 4x + 6
x² + 3x + 2 - 4x - 6 = 0
x² - x - 4 = 0
Therefore,
The equation that can be used to find the value of x is x² - x - 4 = 0

Ann's Trail Mix Recipe 5 cups oats 3 cups seeds 1 cup nuts 2 cups raisins What is the ratio of seeds to total ingredient
Answer:
3/11
Step-by-step explanation:
To find a ratio of one item to another we divide the quantity of the first item to the second.
We know Ann has 3 cups of seeds, and overall 11 ingredients. So her ratio is 3/11. Or 3 cups of seeds for every 11 ingredients.
Answer:
3 : 11
Step-by-step explanation:
Trail Mix Recipe:
5 cups oats3 cups seeds1 cup nuts2 cups raisinsTotal number of cups of all the ingredients:
⇒ 5 + 3 + 1 + 2 = 11
Therefore, the ratio of seeds to total ingredients is:
seeds : total = 3 : 11Note: The ratio cannot be reduced further since both 3 and 11 are prime numbers.

Explain why having a significant linear correlation does not imply causality. Give an example to support your answer.
Correlation may not always indicate causality shown below.
What do you mean by corelation and causation?
We can determine how strongly a pair of variables are linearly associated and change together using the statistical technique of correlation. It only states that there is a relationship; it doesn't explain why or how it came to be. Correlation goes one step farther than causality. It states that any change in one variable's value will result in a change in another variable's value, or that one variable causes the occurrence of another. It also goes by the name "cause and effect."
may not always indicate causality. with a well-known instance.
In New York, ice cream sales and homicide rates are associated (Study)
The frequency of homicides fluctuates along with ice cream sales. Does ice cream consumption result in deaths of people?
No. The mere correlation of two events does not imply causation.
Since correlation does not imply causation in our example, ice cream is not to blame for any fatalities.
There are occasionally some unspoken aspects that are somehow connected. Weather is the underlying factor that drives both ice cream sales and homicide rates, as in our example. The increase in ice cream sales and killings is actually a result of the weather.
Therefore, significant linear correlation does not imply causality.

What happens to y = x when the slope is changed to a number smaller than 1?
Answer:
When the slope of a line is changed to a value that is less than 1, the line becomes less steep. This means that the change in the y-value (the vertical direction) for a given change in the x-value (the horizontal direction) is smaller than it was before. For example, if the original line had a slope of 2 and the new slope is 0.5, the line will be less steep and the change in y for a given change in x will be smaller.

1.35%
13.5%
135% please answer this question. just answer me
The percentage value of 13.5 is 135%
Option D is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
1.35
We will multiply 100 to get the percentage.
Now,
1.35
= 135/100 x 100
= 135%

Use the properties of logarithms to write the expression as a single logarithm, if possible.
By logarithm properties, the logarithmic equation 2 · ㏒ₐ (5 · x³) - (1 / 2) · ㏒ₐ (2 · x + 3) is equivalent to ㏒ₐ [(25 · x⁶) / √(2 · x + 3)]. (Correct choice: A)
How to simplify a logarithmic function by propertiesIn this problems we have a logarithmic equation that must be simplified by means of logarithm properties, all of them described below:
Logarithm of a product of two numbers
㏒ₙ (a · b) = ㏒ₙ a + ㏒ₙ b
Logarithm of a division of two numbers
㏒ₙ (a / b) = ㏒ₙ a - ㏒ₙ b
Logarithm of a power of a number
㏒ₙ aˣ = x · ㏒ₙ a
Now we proceed to reduce the logarithmic equation into a single expression:
2 · ㏒ₐ (5 · x³) - (1 / 2) · ㏒ₐ (2 · x + 3)
㏒ₐ (5 · x³)² - ㏒ₐ √(2 · x + 3)

Happy Card Co. designs personalized cards which cost $1.10 per card. The fixed cost to make the cards is $264 per day. If the company charges $5.10 per card, how many cards must be delivered daily to make a profit of $52? Show work below.
Step-by-step explanation:
x = number of cards
the production costs (PC) per day are
PC(x) = 264 + 1.1x
the sales (S) are
S(x) = 5.1x
the profit (P) per day is sales minus costs
P(x) = S(x) - PC(x) = 5.1x - (264 + 1.1x) =
= 5.1x - 264 - 1.1x = 4x - 264
we need to find the value of x, so that P(x) = 52.
52 = 4x - 264
316 = 4x
x = 316/4 = 79
79 cards must be delivered daily to make a profit of $52.
