y ≥ 0 , Zero possible solution.
What is inequality ?
In mathematics, an inequality represents the connection between two values in an imbalanced algebraic statement. A sign of inequality can be used to show that one of the two variables is larger than, greater than or equal to, less than, or equal to another value.
According to question
a represents the number of tables sold and y represents the number of chairs sold
Using a and y as variables, we get
a + y ≤ 18
100y + 400a ≥ 2900
Simplified,
100(y + 4a) ≥ 2900
y + 4a ≤ 29
Given the minimum number of tables that need to be sold, we evaluate using a = 10
y + 4(10) ≥ 29
y ≥ -11
y represents the number of chairs sold
therefore, y ≥ 0
Since we can't purchase -11 chair, we round up our result giving us y ≥ 0
Now
the store must sell a minimum of 10 tables and tables for $400 each
then
10*400 = $4000
which is more than worth of chairs and tables $2900
hence Zero possible solution.

a= 9 b= 7 and c= 12 Find A , B and C .solve the triangle. Round to the nearest tenth if necessary..
First notice that angle C is a right angle, then:
\(\measuredangle C=90\)Now, since this is a right triangle, we can find the measure of angle A using the trigonometric function sine:
\(\sin \theta=\frac{\text{opposite side}}{hypotenuse}\)In this case, we have the following:
\(\begin{gathered} a=9 \\ c=12 \\ \sin A=\frac{a}{c}=\frac{9}{12}=\frac{3}{4} \\ \Rightarrow A=\sin ^{-1}(\frac{3}{4})=48.6 \\ \measuredangle A=48.6\degree \end{gathered}\)Since the sum of the interior angles of a triangle equals 180, we can find the measure of angle B by solving the following equation:
\(\begin{gathered} \measuredangle A+\measuredangle B+\measuredangle C=180 \\ \measuredangle A=48.6 \\ \measuredangle C=90 \\ \Rightarrow48.6+\measuredangle B+90=180 \\ \Rightarrow138.6+\measuredangle B=180 \\ \Rightarrow\measuredangle B=180-138.6=41.4 \\ \measuredangle B=41.4\degree \end{gathered}\)therefore, angle A measures 48.6 degrees and angle B measures 41.4 degrees
The midpoint of the segment as an ordered pair (-6,-1,) (-1,-6)
Answer:
Step-by-step explanation:
(-6,-1) & (-1,-6)
\(Midpoint=\left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\=\left(\dfrac{-6-1}{2},\dfrac{-1-6}{2} \right)\\\\\\=\left(\dfrac{-7}{2},\dfrac{-7}{2} \right)\\\\\\\)
= (-3.5 , -3.5)
Answer:
\(\boxed{\sf{(-3.5 , -3.5)}}}\)
Step-by-step explanation:
This problem must be solved using the midpoint formula, which is similar to a slope formula.
Midpoint formula: \(\sf{(X_1,Y_1)}(X_2,Y_2)\)
\(\sf{(\dfrac{x_2+x_1}{2},\quad \dfrac{y_2+y_1}{2})}\)
y2=(-6)
y1=(-1)
x2=(-1)
x1=(-6)
Rewrite the problem and then solve it.
\(\left(\dfrac{-1-6}{2},\:\dfrac{-6-1}{2}\right)=-\sf{\dfrac{7}{2}, -\dfrac{7}{2}}\)
Dividing is another option.
-7/2=-3.5
(-3.5, -3.5)
As a result, the final answer is (-3.5, -3.5).

the length of a rectangle is 7 centimeters less than five times its width. its area is 6 square centimeters. find the dimensions of the rectangle.
If the length of a rectangle is 7 centimeters less than five times its width, the dimensions of the rectangle are 2 cm × 3 cm.
Let x be the width of the rectangle in centimeters. Then, the length of the rectangle is 5x - 7 centimeters.
The formula for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width. In this case, we are given that the area is 6 square centimeters, so we can set up the equation:
6 = (5x - 7)x
Expanding the expression on the right side, we get:
6 = 5x² - 7x
Moving all terms to one side, we obtain:
5x² - 7x - 6 = 0
We can now solve for x using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a = 5, b = -7, and c = -6.
Plugging in these values, we get:
x = (7 ± √(7² - 4(5)(-6))) / 2(5)
x = (7 ± √(169)) / 10
x = (7 ± 13) / 10
The two possible values for x are x = 2 and x = -1/5. Since the width cannot be negative, we reject the negative solution and conclude that the width of the rectangle is 2 centimeters. Therefore, the length of the rectangle is 5(2) - 7 = 3 centimeters.

Tree Cutting Problem An Investigation (T/I) I The value of the wood in a tree over time is given by V(t) 224, where Vis the current value of the wood in the tree in S and t is time in years. Ft We have, the discount factor a) Write an equation for the present value of the wood in the tree, A(t) (2 marks) b) Rewrite the present value equation using the natural logarithm (2 marks) c) We want to maximize the present value of the wood, find the first order conditions for a maximum and solve fort". (4 marks) d) If the discount rate, ris 4%, when should we cut the tree down? (2) e) Use the second order conditions to verify that you have indeed found a maximum (2)
a) The present value of the wood in the tree, A(t), can be expressed using the given discount factor F as:
A(t) = V(t) / (1 + r)^t
Where V(t) represents the value of the wood in the tree at time t, and r is the discount rate.
b) To rewrite the present value equation using the natural logarithm, we can use the property of logarithms that states log(a/b) = log(a) - log(b):
A(t) = V(t) * (1 + r)^(-t)
ln(A(t)) = ln(V(t)) - t * ln(1 + r)
c) To find the first-order conditions for maximizing the present value of the wood, we need to differentiate the equation from part (b) with respect to time t and set it equal to zero:
d/dt [ln(A(t))] = d/dt [ln(V(t)) - t * ln(1 + r)] = 0
Solving for t in the above equation will give us the value of t that maximizes the present value of the wood.
d) If the discount rate r is 4%, we can substitute this value into the equation from part (b) and solve for t:
ln(A(t)) = ln(V(t)) - t * ln(1 + 0.04)
Given the specific values for V(t) and A(t) are not provided, we cannot determine the exact value of t in this case.
e) To verify that we have indeed found a maximum, we can use the second-order conditions. This involves taking the second derivative of ln(A(t)) with respect to t and evaluating it at the critical point (t-value obtained from part (c)).
If the second derivative is negative at the critical point, it confirms that the present value of the wood is maximized.

New employees at a company are given a proficiency test. The test scores are approximately normally distributed with a mean of 250 and a standard deviation of 10. A new employee scores 239 on the exam. What is the employee's z-score?
The employee's z-score is -1.1, suggesting that the employee's score is below average compared to other employees who took the proficiency test.
To find the employee's z-score, we need to calculate the number of standard deviations the employee's score is away from the mean. This z-score will tell us how well the employee performed relative to the rest of the population.
1. Calculate the z-score using the formula: z = (x - μ) / σ, where x is the employee's score, μ is the mean, and σ is the standard deviation.
z = (239 - 250) / 10
z = -11 / 10
z = -1.1
2. The calculated z-score of -1.1 indicates that the employee's score is 1.1 standard deviations below the mean. A negative z-score indicates a score below the mean.
In summary, the employee's z-score is -1.1, suggesting that the employee's score is below average compared to other employees who took the proficiency test.
