You have a wire that is 35 cm long. You wish to cut it into two pieces. One piece will be bent into the shape of a square. The other piece will be bent into the shape of a circle. Let A represent the total area of the square and the circle. What is the circumference of the circle when A is a minimum?
The circumference of the circle is 110 m.
What is the circumference of the circle?Let us assume that the wire has been cut into two equal halves thus the radius of the circle would be 35 m/2 = 17.5 m
Then;
C = 2πr
C = circumference
r = radius
"pi" is a mathematical constant approximately equal to 3.14 and "r" is the radius of the circle. If the diameter of the circle is known, the radius can be calculated by dividing the diameter by 2.
C = 2 * 3.142 * 17.5
C = 110 m as we can see here

The rhombus
Also, we have
LN = 14
AN = x + 4
Using the above as a guide, we have the following equation:
LN = 2 * AN
substitute the known values in the above equation, so, we have the following representation
2 * (x + 4) = 14
Evaluate the expression
x + 4 = 7
Subtract 4 from both sides
so, we have the following representation
x = 3
Hence, the solution is 3

Answer:
Step-by-step explanation:
No pressure. You just need to look for the number that when added to the other given number, will give the same as the sum on the other side.
For instance, The top-left question:
4+6 = x+8 (let x be the box)
x= 4+6-8
x=2.
OR, since 4 + 6 =10,
you look for a number when added to 8, that gives 10.

What is the slope of the line that passes through the points ( 6 , 7 ) (6,7) and ( 16 , 22 ) (16,22)? write your answer in simplest form.
Answer:
Step-by-step explanation:
The slope of a line is the change in y (the vertical axis) divided by the change in x (the horizontal axis).
Given the two points (6,7) and (16,22), we can calculate the slope as follows:
Change in y = 22 - 7 = 15
Change in x = 16 - 6 = 10
Therefore, the slope of the line passing through the two points is:
slope = change in y / change in x = 15 / 10 = 3/2
So the slope of the line is in its simplest form, 3/2.

In △ABC', BD is the perpendicular bisector of ADC . Based upon this information, which statements below can be proven? I.BD is a median. II. BD bisects ABC III. △ABC is isosceles.
(1) I and II, only
(3) II and III, only
(2) I and III. only (4) L I and II
Based upon this information, (2) I and III only statements can be proven.
From the given information, we can prove that statement II is true, i.e., BD bisects ABC.
Proof:
Since BD is the perpendicular bisector of ADC, we have AD = CD and ∠ADB = ∠CDB = 90°. Thus, triangles ABD and CBD are congruent (by the hypotenuse-leg congruence criterion), which implies AB = BC and ∠ABD = ∠CBD. Therefore, BD bisects ∠ABC.
However, we cannot prove that statements I or III are true based solely on the given information.
Statement I (BD is a median) would be true if we had additional information that AD = DB = DC, but this is not necessarily true based on the given information.
Statement III (△ABC is isosceles) would be true if we had additional information that AB = BC, but this is not necessarily true based on the given information. In fact, it is only guaranteed that AB = BC if AD = BD = DC, which is not necessarily the case.
Therefore, the correct answer is (2) I and III, only.

Also [tex]\frac{2}{3} rd[/tex] of group A have an A
While 40% of group B have an A
To find:
Fraction of the class that has A
Solution:
First, we find the % of students in group A who have an A:
Since [tex]\frac{2}{3} rd[/tex] of group A have an A,
[tex]\frac{2}{3}[/tex] × [tex]50[/tex] (∵ 1 : 2 = 50 : 100)
[tex]= \frac{100}{3} = 33.33[/tex] (i)
Therefore, % of students in group A who have an A = 33.33%
Now, we find the % of students in group B who have an A:
Since 40% of group B have an A:
[tex]\frac{40}{100}[/tex] × [tex]50[/tex] (∵ 1 : 2 = 50 : 100)
= 4 × 5 = 20 (ii)
Adding (i) and (ii), we get
33.33 + 20 = 53.33%
Thus, the fraction of the class that has an A = [tex]\frac{53.33}{100}[/tex]

What is function?Mathematics is the study of quantities and their variations, equations and related structures, shapes and their locations, and the locations where they can be found. The term "function" refers to the relationship between a set of inputs, each with its own output. A function is a connection between inputs and outputs in which each input leads to a single, distinct result. Each function is assigned a domain and a codomain, also known as a scope. f is commonly used to denote functions (x). The input is an x. Based on the following factors, there are four main types of functions available: on functions, one-to-one functions, many-to-one functions, inside functions, and on functions.

Leila is walking from the park at point P to a restaurant at point R. She wants to stop for a break when the distance she has travelled and the distance she has left to travel has a ratio of 3:5, at which point should Leila stop for her break?
Answer: To determine the point where Leila should stop for her break, we need to find the midpoint of the line segment connecting points P and R, since the midpoint will represent equal distances from both points.
Let the distance between points P and R be d, and let's call the point where Leila stops for her break point B.
Since the ratio of the distance travelled to the distance remaining is 3:5, we know that the distance from B to P is 3/8 of the total distance d, and the distance from B to R is 5/8 of the total distance d.
Therefore, point B is the midpoint of line segment PR, and can be found by dividing the distance between P and R by 2.
Step-by-step explanation:
Write an equation for the line that contains the points (4,-2) and (-2,0)
The linear equation that passes through the two given points is:
y = (-1/3)*x - 2/3
How to write the equation of the line with the two points?A general linear equation can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If a line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know that the line passes through (4, -2) and (-2, 0), then the slope is:
a = (0 + 2)/(-2 - 4)= 2/-6 = -1/3
y = (-1/3)*x + b
To find the value of b, we can replace the values of any of the points in the equation, if we use (-2, 0) we will get:
0 = (-1/3)*-2 + b
0 = 2/3 + b
-2/3 = b
The linear equation is y = (-1/3)*x - 2/3

Assume a TCP sender is continuously sending 1,126-byte segments. If a TCP receiver advertises a window size of 6,353 bytes, and with a link transmission rate 10 Mbps an end-to-end propagation delay of 14.4 ms, what is the utilization? Assume no errors, no processing or queueing delay, and ACKs transmit instantly. Also assume the sender will not transmit a non-full segment. Give answer in percentages, rounded to one decimal place, without units (e.g. for an answer of 10.43% you would enter "10.4" without the quotes).
If a TCP receiver advertises a window size of 6,353 bytes, and with a link transmission rate 10 Mbps an end-to-end propagation delay of 14.4 ms, then the utilization is 0.4%.
What is Round trip time?
The round-trip time (RTT) is the time it takes from when a browser submits a request to when it receives a response from a server, measured in milliseconds.
The time it takes for a segment to be transmitted over the link is:
time per segment = 1,126 bytes / 10 Mbps = 0.00009008 seconds
The end-to-end propagation delay is 14.4 ms, or 0.0144 seconds.
The time it takes for an ACK to be sent back from the receiver is the propagation delay plus the time it takes for the ACK segment to be transmitted over the link:
time for ack = 0.0144 seconds + (1 segment / 10 Mbps) = 0.014508 seconds
The time it takes for the sender to receive an ACK after sending a segment is the time it takes for the segment to be transmitted, plus the time it takes for the ACK to be sent back:
round trip time = time per segment + time for ack = 0.00009008 + 0.014508 = 0.0145
The number of segments that can be in flight at any given time is the window size divided by the segment size:
segments in flight = 6,353 bytes / 1,126 bytes = 5.645 segments
We can now calculate the maximum sending rate of the sender by dividing the number of segments in flight by the round-trip time:
max sending rate = segments in flight / round trip time = 387.165 segments per second
The utilization of the link is the sending rate divided by the link rate, multiplied by 100 to get a percentage:
utilization = (max sending rate / 10 Mbps) * 100 = 0.00387165 * 100 = 0.387165%
Rounding to one decimal place, the utilization is 0.4%.
