Chef Ramsy used 1/4 of a bag of flour to make some muffins and twice as many cupcakes.The amount of flour he used for each muffins was 3 times as much as each cupcake.Chef Ramsy used 5/6 of the remaining bag of flour on a cake.He used 256.5g more flour on the cake than the muffins.
What friction of the bag of flour was used on the muffins?
How much flour was there in the bag at first?
1/4 of the flour was used for the muffins and 5/6 of the remaining flour was used for the cake.
How did we get the values?Let's call the total amount of flour in the bag "x".
The amount used for the muffins is 1/4 of the total bag, or x/4.
The amount used for the cupcakes is twice as much as for the muffins, or 2 * x/4 = x/2.
The amount used for the muffins was 3 times as much as for the cupcakes, so 3 * x/2 = 3x/2 grams of flour were used for muffins.
The amount used for the cake was 256.5 grams more than the muffins, so x/4 + 256.5 = 3x/2.
Solving for x, we find that x = 2048 grams.
So, 1/4 of the flour was used for the muffins, or 2048 * 1/4 = 512 grams.
And 5/6 of the remaining flour was used for the cake, or (2048 - 512) * 5/6 = 1024 grams.

Solve the polynomial (preferably with the X or Box method) g^2+9g+18=0
Answer:
To solve the polynomial (g^2 + 9g + 18 = 0) using the X or Box method, you need to factor the polynomial into two binomials. To do this, you need to find two numbers that multiply to 18 and add up to 9. The two numbers are 6 and 3, so the polynomial can be factored as:
g^2 + 9g + 18 = (g + 6)(g + 3) = 0
To find the solutions, you set each factor equal to 0 and solve for g:
g + 6 = 0, so g = -6
g + 3 = 0, so g = -3
The solutions to the polynomial are g = -6 and g = -3.

The question is asking what the fraction would be, I find it difficult to figure the answer out. I added some pictures, there are actually 6 stages but I can only add 5 attachments.
The fraction of the area of the triangle that would be shaded in stage 7 is equal to 2,187/16,384.
No, there isn't a stage when the fraction of area shaded would be equal to 0.
What is a fraction?In Mathematics, a fraction simply refers to a numerical quantity which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.
Next, we would determine the area of the triangle that would be shaded in stage 2 is as follows;
Fraction of the area = 3/4 × 3/4 = 9/16.
The area of the triangle that would be shaded in stage 3 is as follows;
Fraction of the area = 3/4 × 3/4 × 3/4 = 27/64.
The area of the triangle that would be shaded in stage 4 is as follows;
Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 = 81/256.
Therefore, the area of the triangle that would be shaded in stage 7 is as follows;
Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 = 2,187/16,384.
In this context, we can reasonably infer and logically deduce that there isn't a stage when the fraction of area shaded in this triangle would be equal to zero (0) because there is a linear relationship between the shaded and unshaded area.

Find the Domain, Range, rel. Max and minimum, end behavior, and thr increasing and decreasing intervals.
EQUATION: f(x)=-x^3+8x^2-15x
Step-by-step explanation:
Domain: The domain of the function is all real numbers.
Range: The range of the function is all real numbers less than or equal to 8. To see this, note that the leading coefficient of the polynomial is negative (-x^3), so the function approaches negative infinity as x approaches positive or negative infinity. The largest y-value the function can attain is 8, which occurs at x = 2.
Relative maxima and minima: To find the relative maxima and minima, we find the critical points of the function, which are the values of x that satisfy f'(x) = 0 or f'(x) does not exist. The first derivative of the function f(x) is given by:
f'(x) = -3x^2 + 16x - 15
Solving f'(x) = 0, we get:
-3x^2 + 16x - 15 = 0
x = 1, 5
We also need to determine the concavity of the function near each critical point to determine whether each is a relative maximum or minimum. To do this, we find the second derivative of the function and evaluate its sign at each critical point. The second derivative of f(x) is given by:
f''(x) = -6x + 16
Since f''(x) is always negative, the function is concave down and therefore has a relative maximum at x = 1 and a relative minimum at x = 5.
End behavior: The leading term of the function is -x^3, which means the function approaches negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity. The end behavior of the function is therefore negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity.
Increasing and decreasing intervals: To find the increasing and decreasing intervals of the function, we find the critical points and the sign of f'(x) in the intervals between the critical points.
f'(x) = -3x^2 + 16x - 15
Since f'(x) is negative for x < 1 and positive for x > 1, the function is decreasing for x < 1 and increasing for x > 1. Similarly, since f'(x) is positive for x < 5 and negative for x > 5, the function is increasing for x < 5 and decreasing for x > 5. So, the increasing intervals are (negative infinity, 1) and (1, 5) and the decreasing intervals are (5, positive infinity).

You move the decimal over 5 spaces to the right
a decimal number lies between 0.7 and 0.8 . it has three digits to the right of the decimal point. thus, it is of the following format: it is the largest number between 0.7 and 0.8 .the sum of the digits of this decimal number is 24 . find the decimal number.
The decimal number that lies between 0.7 and 0.8, has three digits to the right of the decimal point, and whose sum of the digits is 24 is 7.98.
A decimal number is a number that has a fractional part represented by a decimal point. The digits to the right of the decimal point represent values that are smaller than 1.
In this problem, we are given that the decimal number has three digits to the right of the decimal point and that its sum of the digits is 24. Let's call the decimal number x. We can write an equation to represent the sum of the digits:
x = a + b/10 + c/100
Where a, b, and c are the digits of x.
We know that 0.7 < x < 0.8 and that the sum of the digits of x is 24, so we can write two more equations:
0.7 < a + b/10 + c/100 < 0.8
a + b + c = 24
By solving these three equations, we can find the decimal number x.
We know that a must be 7 because 0.7 < x < 0.8, so a = 7. We also know that b + c = 24 - 7 = 17. Now we need to find two digits b and c such that b + c = 17 and b/10 + c/100 is between 0 and 0.1.
The largest value of b that still satisfies this condition is 9. This means that
=> c = 17 - 9 = 8.
Therefore, the decimal number
=> x = 7 + 9/10 + 8/100 = 7.98.

When polarized light with intensity [tex]I_{0}[/tex] strikes a polarized filter with its axis at an angle θ with the vertical, the intensity of the transmitted light, [tex]I_{t}[/tex], depends on the angle θ and the original intensity [tex]I_{0}[/tex]. The relationship between [tex]I_{t}[/tex] and [tex]I_{0}[/tex] is described by the equation cosθ = [tex]\sqrt\frac{I_{t} }{I_{0} }[/tex].
If θ = 45°, then the equation θ can be simplified to cos 45° =[tex]\sqrt\frac{I_{t} }{I_{0} }[/tex].
The cosine of 45° is equal to [tex]\frac{1}{\sqrt{2} }[/tex], so we have:

- The weight of an object having mass 5kg is 450 N weight of another object having mass 50kg is 147N. Check weather the mass and we weight are proportional What is the constant of proportionality
Answer:
see below
Step-by-step explanation:
We are here given that weight of an object having mass of 5kg is 450N .
As we know that,
Weight = mass * acceleration due to gravity (g)
So that ,
450N = g * 5kg
g = 450/5 m/s²
g = 90m/s²
Again in second case,
147N = g' * 50kg
g' = 147/50 m/s²
g' = 29.4 m/s²
since here g ≠ g'
Therefore,
mass and weight are not promotional in this case. This may be due to the fact that the acceleration due to gravitational force of each celestial object is different and weights may have been measured on different planets.
And the constant of proportionality is g ( acceleration due to the gravitational force) .
And we are done!
looking at the side-by-side boxplots from the previous question, should the mean for boxplot #3 be less than, greater than, or roughly equal to its median?
The mean for boxplot #3 should be less than its median. In a negatively skewed distribution, the mean is less than the median.
This is because the few small values in the data pull the mean down, while the median is still at the middle value. A boxplot can give us an idea of the shape of the distribution, and if it is negatively skewed, it suggests that the mean will be less than the median.
It's important to note that without actually seeing the boxplot, this conclusion may not be accurate. There could be other factors that affect the mean and median, such as outliers or the size of the sample. However, based on the information given that the boxplot is negatively skewed, it is likely that the mean will be less than the median.

the value of the optimal solution is 28.5. suppose that the right-hand side for constraint 1 is increased from 10 to 11. (a) use the graphical solution procedure to find the new optimal solution. what is the value of the objective function at the optimal solution?
The linear program has an optimal solution of 28.5 at (A, B) = (2, 5) when the right-hand side for constraint 1 is 10. If the right-hand side is increased to 11, the optimal solution remains 28.5 at the same point.
The dual value for constraint 1 stays the same as long as the right-hand side stays within the range 8.4 to 11. The value of the optimal solution will increase by 0.5 for every unit increase in the right-hand side of constraint 2 as long as the right-hand side is within the range 23 to 27.
a) To find the new optimal solution, we need to graph the feasible region and find the new corner points. After the change, the first constraint becomes 1A + 1B ≤ 11. The other two constraints remain the same. The corner points can be found by substituting the bounds of each variable into the constraints and solving for the other variable. The feasible region can then be graphed, and the maximum of the objective function can be found at one of the corner points.
The new corner points are (0,0), (0,9), (6,0), and (2,5). The feasible region can be graphed as a triangle with these corner points. The maximum of the objective function 3A + 2B occurs at the point (2,5), where the value of the objective function is 28.5.
b) The value of the objective function at the optimal solution is 28.5, at (A, B) = (2, 5).
c) The right-hand side range information for constraint 1 tells us that if the right-hand side is increased from 10 to 11, the dual value will remain the same (since the allowable increase is 2.6 and the right-hand side only increases by 1). The range for constraint 1 is 8.4 to 11. As long as the right-hand side stays within this range, the dual value of 2.6 is applicable.
d) The dual value for constraint 2 is 0.5. Using this dual value and the right-hand side range information, we can conclude that the value of the optimal solution will increase by 0.5 for every unit increase in the right-hand side of constraint 2 as long as the right-hand side is within the range 23 to 27.

The number of subs in the order is 8 or 9
how many subs are in the order?Let's call the number of subs in the order "x".
Since the cost of 3 subs is $20, the cost per sub is $20 / 3 = $6.67.

C. 2
D. -2
E. -4
In the diagram, AC is a diameter of circle O. If the slope of BC is -1/2, then the slope of AB is 2.
What is the diameter of the circle?
The diameter of a circle is the length of the line starting from one point on a circle to another point and passing through the center of the circle. It is equal to twice the radius of the circle.
We have that,
ABC is a right triangle
so,
AB is perpendicular to BC
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1.
so,
m1 * m2 = -1
in this problem
mAB * mBC =-1
solve for mAB
mAB = -1 / mBC
mAB = -1 / -1/2
mAB = 2
therefore, In the diagram, AC is a diameter of circle O. If the slope of BC is -1/2, then the slope of AB is 2.
