Be Allison has been to the large muffin sale table Chris wants to pay more signs
By proportion, Chris should mix 8/3 parts of the red paint in 2 fluid ounces of blue paint.
Purple paint is made using a combination of red paint and blue paint.
Now Allison made purple paint by mixing 3 parts red [aint and 4 parts blue paint.
Therefore, the ratio for the purple paint is :
= 4 parts blue paint / 3 red paint
Chris has 2 fluid ounces of blue paint.
Let the amount of red paint Chirs have to be x.
Then the proportion should be equal.
So,
4 / 3 = x / 2
By cross multiplication,
4 × 2 = 3 × x
8 = 3x
Dividing each side by 3,
x = 8/3
Chirs should mix 8/3 parts of the red paint with blue paint.

Answer:
(6√13)/13
Step-by-step explanation:
You want the exact value of cot(arcsin(√13/7)).
Trig ratiosThe relevant trig ratios are ...
Sin = Opposite/Hypotenuse
Tan = Opposite/Adjacent
Cot = 1/Tan = Adjacent/Opposite
Pythagorean theoremThe Pythagorean theorem can be used to find the side adjacent to the angle whose sine is √13/7. Using the sine ratio, we can take the opposite side to be √13, and the hypotenuse to be 7. Then the adjacent side is ...
adjacent² +opposite² = hypotenuse²
adjacent² +(√13)² = 7²
adjacent² = 49 -13 = 36
adjacent = √36 = 6
CotangentThen the cotangent of the angle is ...
cot(arcsin(√13/7)) = adjacent/opposite = 6/√13
cot = (6√13)/13

The linear equation y = -500x + 5000 models the price-sales relationship for the toy and the daily sales of the toy would be $1250 if the price is set at $7.50.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The line must pass through points (6, 2000) and (8,1000) which is given in the question.
We have to determine the slope of the line :
m = (y₂ - y₁)/(x₂ -x₁ )
m = (1000 - 2000)/(8 - 6)
m = -1000/2
m = -500
This represents new assistants per year
So with through points (6, 2000) and (8,1000), the equation becomes
y - 2000 = -500(x -6)
y = -500x + 3000 + 2000
y = -500x + 5000
Using this equation to predict the daily sales of the toy if the price is set at $7.50.
Assume that the ratio of change in price to change in daily sales is constant and let x be the price of the toy and y be the number of sales.
Substitute the value of x = 7.50
y = -500(7.50) + 5000
y = -56000 + 294000
y = 1250
Hence, the daily sales of the toy would be $1250 if the price is set at $7.50.

-3×+9=-3(2×+3)+3(×-4)+1
The expression we have is:
[tex]-3x+9=-3(2x+3)+3(x-4)+1[/tex]Step 1. To solve for x, we need to first apply the distributive property on the right-hand side of the equation. The distributive property is to multiply the number outside each pair of parenthesis by the terms inside it. We get the following:
[tex]-3x+9=-3\cdot2x-3\cdot3+3\cdot x+3\cdot(-4)+1[/tex]Solving the multiplications on the right-hand side:
[tex]-3x+9=-6x-9+3x-12+1[/tex]Step 2. Combine the like terms.
We start by combining the terms that contain x:
[tex]-3x+9=-3x-9-12+1[/tex]And then, combine the independent terms:
[tex]-3x+9=-3x+4[/tex]Step 3. Add 3x to both sides of the equation:
[tex]-3x+3x+9=4[/tex]On the left side, we get that -3x+3x cancel each other:
[tex]9=4[/tex]As we can see, this is not true, which means that there is no solution for x.

This month, a vegetarian restaurant used 9,168 ounces of spinach. That is 20% more than last month, when the restaurant had a different menu. How much spinach did the restaurant use last month?
Consider 9,168 ounces of spinach is 20% more than the amount of spinach of the last month. If x is such unknown amount of spinach, you can write:
[tex]x+(\frac{20}{100})x+9,168[/tex]where (2/100)x factor represents the 20% of x.
Simplify the pervious equation and solve for x:
[tex]\begin{gathered} x+0.2x=9,168 \\ 1.2x=9,168 \\ x=\frac{9,168}{1.2} \\ x=7,640 \end{gathered}[/tex]Hence, last month the restaurant used 7,640 amount of spinach.

Which of the following inequalities would have the solution set graphed below?
t - 2 ≤ 0
t - 3 ≤ 5
t + 2 ≤ 0
t + 3 ≤ 1
Answer:
t - 2 ≤ 0
Step-by-step explanation:
Given inequality
t- 2 ≤ 0
Add 2 on both sides of the inequality without changing the meaning
t - 2 + 2 ≤ 0 + 2
or
t ≤ 2
Looking at the number line given, we can see that all numbers to the left of 2 including 2 are part of the solution set
Hence the solution set graphed is t- 2 ≤ 0

What is the value of X?What is the value of the radius In circle O?
Answer
x = 4.5 units
Radius = 29 units
Explanation
The center of the circle is point O.
So, any line drawn from that point O to any point on the circumference of the circle is the radius of the circle and will therefore have the same length.
Therefore, OC = OD
OC = 6x + 2
OD = 10x - 16
6x + 2 = 10x - 16
Rewriting this
10x - 16 = 6x + 2
10x - 6x = 2 + 16
4x = 18
Divide both sides by 4
(4x/4) = (18/4)
x = 4.5 units
Then, we can now calculate the radius of the circle now
Radius = OC = OD
= 6x + 2 or 10x - 16
= 6(4.5) + 2 or 10(4.5) - 16
= 27 + 2 or 45 - 16
= 29 units.

this morning the temperature was "-12" degrees. the temperature will rise 5/8 degree every hour for 3 hours before dropping 1/2 degree each hour for 5 hours. what is the temperature after 8 hours
Using proportions, it is found that the temperature after 8 hours is of -12.63 degrees.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using arithmetic operations such as multiplication or division considering the given rates in the function.
The temperature is of -12 degrees, and rises by 5/8 every hour for 3 hours, hence the temperature in 3 hours will be given by:
-12 + 3 x 5/8 = -12 + 15/8 = -10.13 degrees.
Then, for each of the next 5 hours, the temperature drops by 0.5 degrees, hence the temperature after 8 hours will be given by:
-10.13 degrees - 5 x 0.5 = -10.13 - 2.5 = -12.63 degrees.

Given the series:
[tex]1-\frac{1}{3}+\frac{1}{9}-...[/tex]State if the series is convergent or divergent and if convergent, find its sum.
The sequence of terms forms a geometric pattern. Each term is found by multiplying the previous term by a constant number (the common ratio).
Let's find the value of the common ratio by dividing any two successive terms, for example:
[tex]r=\frac{-\frac{1}{3}}{1}=-\frac{1}{3}[/tex]The common ratio is greater than -1 and less than 1, so the series is convergent.
Now we find the sum of the infinite series by using the formula:
[tex]S=\frac{t_1}{1-r}[/tex]Where t1 is the first term, that is, t1 = 1.
Substituting:
[tex]S=\frac{1}{1-\left(-\frac{1}{3}\right)}[/tex]Now we add the numbers to the denominator:
[tex]S=\frac{1}{1+\frac{1}{3}}[/tex]We have a sum of an integer and a fraction:
[tex]1+\frac{1}{3}[/tex]To add these numbers, we must get them to have the same denominator, thus:
[tex]1+\frac{1}{3}=\frac{3}{3}+\frac{1}{3}=\frac{4}{3}[/tex]Operating:
[tex]S=\frac{1}{\frac{4}{3}}[/tex]To divide by a fraction, we multiply by its reciprocal:
[tex]S=1\cdot\frac{3}{4}=\frac{3}{4}[/tex]4. What is the value of y in the system of equations shown below?

The measure of an angle is 28.5°. What is the measure of its complementary angle?
When the measure of an angle is 28.5° then the angle measure of its complementary angle will be 61.5°.
What is complementary angle?They are referred to as complementary angles when the sum of two angles is 90 degrees. For instance, the angles of 30 degrees and 60 degrees complement one another.
If we know the measurement of one angle, we can easily find the unknown angle because the sum of complementary angles equals 90 degrees.
As an illustration, if one of the two angles is 45 degrees, then the formula is:
x + 45 = 90
x = 90 - 45 = 45°.
If 2 complementary angles adds up to 90°
So the complementary angle of 28.5° is
90° - 28.5° = 61.5°
Thus, the angle measure of its complementary angle will be 61.5°.

Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation, followed by a translation of 3 units down.
Step-by-step explanation:
If two triangles are said to be similar, their corresponding angles are congruent and their corresponding sides are in the same ratio.
Given vertices of triangle ABC:
A = (0, 0)B = (1, 4)C = (5, 2)To maintain similarity but not maintain congruence, dilate triangle ABC (since dilation keeps the corresponding angles of both triangles the same).
Given vertex of triangle A'B'C':
B' = (2, 5)If ΔABC is dilated by a scale factor of 2, with the origin as the center of dilation, B' = (2, 8). If the triangle is then translated 3 units down, B' = (2, 5), which matches the given coordinate of point B'.
Therefore, the series of transformations is:
Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation.Translation of 3 units down.Mapping Rule: (x, y) → (2x, 2y - 3)
Therefore, the coordinates of point C' are:
