The given statement to this question is true
What is an optimal solution?
An acceptable solution where the objective function reaches its highest (or minimum) value, such as the most profit or the lowest cost, is referred to as an optimal solution. When there are no other practical solutions with superior objective function values, the solution is said to be globally optimal.
Here, we have
The global optimum point may be superior to nearby points, but the local optimum point is the true optimal solution to a nonlinear programming problem.
Because when own linear model is solved this solution is merely local optimum.
The solver should consider that other local optimum Amy does not exist with better object values. The globally optimal solution is one where there are no feasible solutions with a better objective function.
However many nonlinear problems are non-convex and are likely to have multiple locally optimal solutions. The local optimum point is the true optimal solution for the nonlinear programming model.

Mr. Lang bought a coat and a pair of gloves for each of his 13 grandchildren. A coat cost of $30 and a pair of gloves costs $6.49. What was Mr.Lang's total purchase?
Answer:
Mr. Lang bought a coat and a pair of gloves for each of his 13 grandchildren, so he bought 13 coats and 13 pairs of gloves.
Each coat cost $30, so the total cost of the coats was 13 coats * $30/coat = $<<13*30=390>>390.
Each pair of gloves cost $6.49, so the total cost of the gloves was 13 gloves * $6.49/glove = $<<13*6.49=84.37>>84.37.
The total cost of the coats and gloves was $390 + $84.37 = $<<390+84.37=474.37>>474.37.
Therefore, Mr. Lang's total purchase was $474.37.

Hue is arranging chairs. She can form 2 rows of a given length with 8 chairs left over, or 8 rows of that same length if she gets 10 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.
The number of chairs that are in that row length is 3.
How to illustrate the equation?Let the chairs in 1 row be x
Let the total chairs be y.
Since Hue can form 2 rows of a given length with 8 chairs left over, this will be:
y = 2x + 8
Also, it can be 8 rows of that same length if she gets 10 more chairs. This will be:
y = 8x - 10
Combine the equations
2x + 8 = 8x - 10
Collect like terms
8x - 2x = 10 + 8
6x = 18
Divide
x = 18 / 6
x = 3

The speed of light is 299,792 kilometers per second. Zipporah tried converting the speed light to miles per hour using the following equivalencies:
1 km = 0.62 mi
1 min = 60 s
1 hr = 60 min
How fast is the speed of light in miles per hour?
The speed of the light in miles per hour is
66913574.4 miles per hour
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1 hour = 60 minutes
We have,
1 km = 0.62 mi
1 min = 60 s
1 hr = 60 min
Speed of light = 299,792 km per second
This can be written as,
1 km = 0.62 miles
299792 km = 299792 x 0.62 miles
299792 km = 185871.04 miles
1 hour = 60 minute
1 hour = 360 seconds
1/360 hour = 1 second
1 second = 1/360 hour
Now,
= 299792 km / 1 second
= 185871.04 miles / 1/360 hour
= 185871..04 x 360 miles per hour
= 66913574.4 miles per hour
Thus,
The speed of the light is 66913574.4 miles per hour.

Which compound inequality has no solution?
= x+5<5 and ²x+¹>1

O 3(x+4) < 12 or 3x + 1 > 10
2x+1
O10<3(x-2) + 1 or
3
O 11 ≤ 5(x + 3) - 9 and 5(x + 3) - 9 <21
<2
ہے
Answer:
The compound inequality that has no solution is 3(x+4) < 12 or 3x + 1 > 10. To solve this inequality, we need to first consider each inequality separately. For the first inequality, 3(x+4) < 12, we can solve for x by dividing both sides of the inequality by 3, like this:
(x+4) < 4
x < 0
This means that the solution to the first inequality is all values of x that are less than 0. For the second inequality, 3x + 1 > 10, we can solve for x by subtracting 1 from both sides of the inequality and then dividing by 3, like this:
3x > 9
x > 3
This means that the solution to the second inequality is all values of x that are greater than 3.
Now that we have the solutions to each inequality, we need to combine them to find the solution to the compound inequality. To do this, we need to consider the "or" that connects the two inequalities. This means that the solution to the compound inequality is the set of values that are either less than 0 or greater than 3. Since there are no values that are both less than 0 and greater than 3, this compound inequality has no solution. The other compound inequalities listed have solutions, so they are not the answer to the question.

(ITS DUE IN 30 MINUTES)Frigidia is a colony in Antarctica. The colony is 1,000 square kilometers in size. Currently, 30,000 people live there. Last year, 10,000 children were born and 2,000 people immigrated. 20,000 people died and 5,000 emigrated. It is believed that the island could support up to 50 people per square kilometer.
The current growth rate is ___.
43%
-43%
4.3 %
-4.3%
The current growth rate of the island is given as follows:
-43%.
How to calculate the growth rate?The first step in calculating the growth rate is obtained the increases and the decreases in the population, as follows:
Increases: 10,000 births + 2,000 people immigrating = 12,000.Decreases: 20,000 deaths + 5,000 people emigrating = 25,000.The total change is obtained by the subtraction of the increases by the decreases, as follows:
Total change = 12,000 - 25,000 = -13,000
Then the growth rate, as a percentage, is obtained by the division of the total change of -13,000 by the initial population of 30,000 and then multiplied by 100%, as follows:
-13,000/30,000 x 100% = -43%.

When a car travels 100 km at a speed of 60km/h and returns back with a speed of 40km/h What will be average speed for whole journey?
The average speed of the whole journey of car based mentioned speeds is 48 km/hr.
The average speed is calculated by the formula -
average speed = total distance covered ÷ total time taken. The total distance covered is sum of distance of first and return journey. Total distance covered = 100 + 100
Performing addition
Total distance covered = 200 kilometres
Now total time taken = time taken on first journey + time taken for return journey
Total time taken = distance/speed + distance/return speed
Total time taken = 100/60 + 100/40
Performing division
Total time taken = 5/3 + 5/2
Total time taken = 10 + 15/6
Total time taken = 25/6 hour
Average speed = 200/(25/6)
Average speed = (200×6)/25
