a wire is to be cut into two pieces. one piece will be bent into a square, and the other piece will be bent into a circle. if the total area enclosed by the two pieces is to be 144 m2, what is the minimum length of wire that can be used?
A wire is cut into two pieces, one piece bent into square and other piece will be bent into circle. Therefore, the minimum length of wire that can be used is 43 m.
The relationships between the radius of a circle and its circumference and area are :
C = 2πr
A = πr²
The relationships between the side length of a square and its perimeter and area are :
P = 4s
A = s²
So, the length of wire will be
W= C + P
W = 2πr + 4s
Subject to the constraint that the sum of areas is 144 m²:
πr² + s² = 144
Using the method of Lagrange multipliers to find the extremes of wire length, we want to set the partial derivatives of the Lagrangian (L) to zero.
L = 2πr + 4s + λ(πr² +s² -144)
∂L/∂r = 0 = 2π +2πλr ------------------------------- (1)
∂L/∂s = 0 = 4 +2λs ------------------------------- (2)
∂L/∂λ = 0 = πr² +s² -144 -------------------------------- (3)
Solving for λ, we find,
1 +λr = 0 ---------------------------- (4)
⇒ λ = -1/r ----------------------------- (5)
Substituting into equation (2), we get,
4 + 2(-1/r)s = 4
⇒ s/r = 2 -------------------------------- (6)
This tells us the maximum wire length is that which makes the circle diameter equal to the side of the square.
Substituting the relation s=2r into the area constraint, we find,
πr² +(2r)² =144
⇒ r = √(144/(π+4))
⇒ r= 12/√(π+4) ≈ 2.068965 . . . m
∴ The minimum wire length will be required when the entire area is enclosed by the circle. In that case,
πr² = 144
⇒ r = √(144/π)
and, C = 2πr
= 2π√(144/π)
= 24√π ≈42.5388 . . m
rounding up the minimum value 42.5388... in 43.
∴ The minimum wire length will be required is 43 m

Using theories of Rhode island ,we got that when the British ship Gaspee ran a ground in Rhode island, the local population 1) burned it.
On June 9, Gaspee gave chase to the packet ship Hannah, but the Gaspee ran aground in shallow water on the northwestern side of bay on what is now Gaspee Point. Her crew were unable to free her and the Dudingston decided to wait for the high tide, which would possibly set the vessel afloat. Before that could happen, however, the band of Providence men led by John Brown decided to act on a "opportunity offered of putting an end to the trouble and the vexation she daily caused." They rowed out to the ship and boarded at the break of dawn on June 10.

of the horizontal side is the same for each triangle. These quotients are slopes

Slope of a line with given points (x₁, y₁) and (x₂, y₂) is
Slope, m = (y₂ -y₁) /(x₂-x₁)Here we have
Points (1, 31) (5, 155) and (9, 279)
We need to find slopes between two points
As we know the formula for slope with given points is
Slope, m = (y₂ -y₁) /(x₂-x₁)
Here coordinates of the origin are (0, 0)
The slope between (0, 0) and (1, 31)
=> m = (31 - 0) /(1 - 0) = 31/1 = 31
The slope between (0, 0) and (5, 155)

The possible numbers of additional miles that Lamar can run are all the solutions of the inequality:
0 ≤ x ≤ 15
What are the possible numbers of additional miles?We know that Lamar will run at most 37 miles this week, and he already did run 22 miles, then the (maximum) distance left this week is:
D = 37mi - 22mi = 15mi
So he can run at most 15 miles, this means that he can run any distance between 0 miles and 15 miles by the end of the week.
So, if we define x as the distance that he will run on the week (in miles), then we can write the inequality:
0 ≤ x ≤ 15
so the possible numbers of additional miles he will run on this week are all the values of x that are a solution for the above inequality.

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Alisa can work at most 30 hours next week, but she needs to earn at least $240. Her lawn mowing job pays $9 an hour, and her coaching job pays $15 an hour. Identify the variables, and then write a system of equations to represent the constraints on Alisa's work time and income.
The system of equation for the following conditions contains equation the equations: x + y ≤ 30 and 9x + 15y 240.
What is system of equation?
A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."
Let the hours Alisa work for lawn mowing job is "x" hours and for coaching job is "y" hours.
As given in the question, Alisa can work at most 30 hours.
So the total working hours should be equal or less that 30 hours.
Therefore, the first equation can be written as:
x + y ≤ 30
And it is also given that, she needs to earn at least $240, while Her lawn mowing job pays $9 an hour, and her coaching job pays $15 for an hour.
So, Total earning = per hour earning x total hour
lawn mowing job earning = 9(x)
coaching job earning = 15(y)
Therefore, the second equation can be written as:
9x + 15y 240
Hence, the system of equation is: x + y ≤ 30 and 9x + 15y 240

What is Markov Process?
A Markov chain or Markov process is a stochastic model that depicts a series of potential occurrences where each event's likelihood is solely determined by the state it reached in the preceding event.
First, take notice that the frog has a probability of 1/2 of finally being eaten by the snake once it is on pad 5, and a probability of 1/2 of eventually emerging from the pond unharmed. Therefore, all that needs to be determined is the probability that the frog on pad 1 will make it to pad 5 without being eaten.

Because the frog will ultimately make it to pad 5 or pad 1 from pad 3, the probability that it ultimately makes it to pad 5 is [tex]\frac{42}{100}[/tex] ÷ [tex]( \frac{42}{100} +\frac{6}{100} )=\frac{7}{8}[/tex] and the probability that it ultimately makes it to pad 1 is [tex]\frac{6}{100}[/tex] ÷ [tex](\frac{42}{100} +\frac{6}{100} )=\frac{1}{8}[/tex]
The series of steps that must be made in pairs for the frog to get to pad 5 without being eaten is

The ratio of words missed to correct on Marcy’s test was 1:4 if she got 4 words wrong, how many were correct
Answer:
Marcy got 16 wrong.
Step-by-step explanation:
You simply multiply 1 ( from the missed side of the ratio ) by 4 ( how many Marcy got wrong ) which equals 4. Then you do the same to the other side. 4 ( from the "correct" side of the ratio ) by 4 ( how many Marcy got wrong ). 4 x 4 is 16. So, Marcy got 16 wrong.
Answer:
16
Step-by-step explanation:
The ratio is 1:4 means for 1 wrong word, she got 4 words correct. If she has 4 words wrong, multiply that with 4 and you got 16.
