What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured
According to our question-
The velocity in this problem is the average walking speed, hence the distances in the table are calculated by dividing the time in the same row by the velocity.
The velocity is reported as follows for the first row:
2.5 miles per hour is equal to v = 0.5/(12/60) = 0.5/0.2.
The minutes are split by 60 because the time is in hours.
The velocity is stated as follows for the second row:
1.5 x 4/3 divided by 45/60 equals 2 miles per hour, or v.
The velocity is given as follows for the third row:
v = 0.75 x 4 x (15/60) = 4 miles per hour.
Hence, 4 miles per hour.

What is a tangent ?
A tangent in geometry is a line that originates at an outside point and travels through a curve's Centre. When you ride a bicycle, every point on the wheel's circumference forms a tangent with the road, providing a practical illustration of a tangent. Let's use an illustration to better grasp what a tangent is. The arc S and point P outside of S are depicted in the following figure. S has been reached via a tangent from P. This serves as an illustration of a tangent.
Two crucial characteristics of the tangent are:
A tangent only hits a curve once.
A line that never reaches the inside of the circle is known as a tangent.
At the point of tangency, the tangent makes a right angle contact with the circle's radius.
A tangent to the circle also has mathematical theorems linked with it, which are needed when doing important computations in geometry in addition to the qualities mentioned above. Let's go into further depth on a couple tangents to circle theorems.

The equation is __n + __ = __
. The triplets are _______ years old.
Answer:
9
Step-by-step explanation:
Equation
[tex]3n + 11 = 38[/tex]
3n=38-11
n=27/3
n=9
therefore triplets are 9 years old
Check
[tex]3n + 11 = 38[/tex]
[tex]3 \times 9 + 11 = 38 \\ 27 + 11 = 38 \\ 38 = 38[/tex]
Answer:
equation: 3n+11=38
The triplets are 9 years old.
Step-by-step explanation:
3n : triplets x their age
11 : the sum
38 : the sum of the ages
We must isolate n to know their age so,

Find the value of x and y in the below diagram. TL is the perpendicular bisector of BF. TE = 2x - 10, EL = 8x-17, BE = 3x+6, and BF = 7x-5, m
Hello,
I hope you and your family are doing well!
To find the value of x, we can use the fact that TL is the perpendicular bisector of BE. This means that TL splits BE into two segments of equal length. Therefore, we have:
EL + BF = BE
Substituting the values for EL, BF, and BE gives:
[tex](8x - 17) + (7x - 5) = (3x + 6)[/tex]
Combining like terms gives:
[tex]15x - 22 = 3x + 6[/tex]
Subtracting 3x from both sides gives:
[tex]12x - 22 = 6[/tex]
Adding 22 to both sides gives:
[tex]12x = 28[/tex]
Dividing both sides by 12 gives:
[tex]x = 28/12 = 7[/tex]
Now that we know the value of x, we can use this value to find the value of y. We can use the equation TE = 2x - 10 to find the value of TE:
TE = 2x - 10 = 2 * 7 - 10 = 14 - 10 = 4
Now we can use the equation EL = 8x - 17 to find the value of EL:
EL = 8x - 17 = 8 * 7 - 17 = 56 - 17 = 39
Since TL is the perpendicular bisector of BE, the length of TL is the average of the lengths of EL and TE. The average of EL and TE is:
(EL + TE)/2 = (39 + 4)/2 = 43/2 = 21.5
So the length of TL is 21.5, and the value of y is 21.5 and x is 7

What is a circle?The circle is a 2D geometrical figure, with no side or angle, and is made a collection of points.
Given that, 1) a circle with circumferences = 2πr and radius = r, 2) a circle having circumferences = 76 cm and 3) Jada is painting a table having diameter 37 in.
1) Assume the figure as a rectangle, (refer to attached figure)
We get, the length of it is πr and width is r.
And the area of a rectangle is = the Product of length and width.
So, we can conclude that the area of this rectangle is = πr×r = πr²
Therefore, by assuming the figure as a rectangle, we can explain why the area of a circle is πr²
2) circumferences = 2πr
2πr = 76
πr = 38
r = 38/3.14 (π ≈ 3.14)
r = 12.01 cm
Diameter = 2r
D = 2x12.01 = 24.20 cm
Area = πr²
= 3.14x12.01²
= 452.91 cm²
3) Diameter = 37 in
r = 37/2 = 18.5 in
Area = πr²
= 3.14x18.5²
= 1074.66 in²
Therefore, the area of the table is 1074.66 in²
Hence, the answers are 1) We can explain why the area is πr² by assuming the figure as a rectangle, 2) Diameter = 24.20 cm, Area = 452.91 cm² and 3) the area of the table is 1074.66 in²

Both engines were equally hot
The correct option is B in the given Temperature problem by Calculation T ≈ 26.4 + (20 - 8.8) × (28.8 - 26.4) / (11.1 - 8.8) ≈ 27.7 degrees Celsius,
T ≈ 55 + (20 - 10) × (60 - 55) / (20 - 10) ≈ 60 degrees Celsius
According to the given information:
For the first question, we need to compare the rate of change of temperature with respect to rotation speed for both engines. We can do this by calculating the difference in temperature for a change in rotation speed of 111 cycles per second for both engines.
For the first engine, the temperature increased by:
31.2 - 28.8 = 2.4 degrees Celsius
For the second engine, the temperature increased by:
60 - 50 = 10 degrees Celsius
Since the temperature increase for the second engine is greater, we can conclude that the second engine's temperature increased more for each increase of 111 cycles per second. Therefore, the answer is (B) The second engine.
For the second question, we can use linear interpolation to estimate the temperature of each engine at 20 cycles per second.
For the first engine, we can use the two closest data points (8.8 and 11.1 cycles per second) to estimate the temperature at 20 cycles per second:
T ≈ 26.4 + (20 - 8.8) × (28.8 - 26.4) / (11.1 - 8.8) ≈ 27.7 degrees Celsius
For the second engine, we can use the same method with the two closest data points (10 and 20 cycles per second):
T ≈ 55 + (20 - 10) × (60 - 55) / (20 - 10) ≈ 60 degrees Celsius
Therefore, we can conclude that the second engine was hotter when it rotated at 20 cycles per second. The answer is (B) The second engine.

Peter enters a hot dog eating contest. Peter's friend calculates that on average, Peter eats 2 hot dogs per minute. They write the equation y = 2x in order to predict how many hot dogs Peter can eat in a 30-minute contest, where x stands for the amount of time in minutes and y stands for the total number of hot dogs.
A) Does the equation represent a proportional relationship? Explain your reasoning.
B) What is the unit rate of change for this situation?
Answer:
A) The equation y = 2x represents a proportional relationship. This is because the values of y are directly proportional to the values of x. In other words, as x increases, y also increases by the same factor. This is the definition of a proportional relationship.
B) The unit rate of change for this situation is 2 hot dogs per minute. This is because the equation y = 2x represents a linear relationship, where the rate of change (the slope) is constant. The unit rate of change is the slope of the line, which in this case is 2. This means that for every 1 minute that passes, Peter eats 2 hot dogs.
The smaller of two numbers is one more than half the larger number. If their sum is 133, write an equation to solve for the two numbers.
Answer:
The two numbers are 44 as the smaller number and 89 as the larger number.
Step-by-step explanation:
Hope it helps!
Let's call the larger number x, and the smaller number y. We know that y is one more than half of x, so we can write y = x/2 + 1. We also know that the sum of the two numbers is 133, so we can write x + y = 133. We can use these two equations to solve for the values of x and y. Substituting the first equation into the second, we get:
x + (x/2 + 1) = 133
Combining like terms, we get:
1.5x + 1 = 133
Subtracting 1 from both sides, we get:
1.5x = 132
Dividing both sides by 1.5, we get:
x = 88
Substituting this value for x in the first equation, we get:
y = 88/2 + 1 = 44 + 1 = 45
Therefore, the two numbers are 88 and 45, and we can check our solution by verifying that the sum of these numbers is indeed 133.
x + y = 88 + 45 = 133
This confirms that our solution is correct.

Answer:
a = 84°
b = 21°
c = 48°
Step-by-step explanation:
Step 1.)
The first step is recognizing the angle of 75° is sticking out from a straight-line, PQ. That straight-line represents an angle of 180°
180°-75° = 105 = a° + b°
Step 2.)
We also know that the line RS is 180°. Therefore, it must be true that
75° + 4b° + b° = 180°
or simply
5b + 75 = 180°
Now solve for b. Subtract both sides by 75 and divide the right side by 5
5b = 105°
b = 21°
4b° = 4 x b = 4 x 21° = 84° = 4b°
Step 3)
Since we know that a + b = 105°, we use substitution to get:
a + 21° = 105
Now subtract both sides by 21
a = 84°
Now let's double check if a + b + 75 = 180
84 + 21 + 75 = 180 [check]
Step 4.)
Since we know that PQ is a straight-line that is 180°, we can say:
180° = 4b° + 2c°
Now substitute 4b with 84°
180° = 84° + 2c
Now solve by subtracting 84 from 180 and divide by 2, if needed.
96° = 2c°
48° = c°
Now double check
96° + 84° = 180° [check]
Therefore:
a = 84°
b = 21°
c = 48°
Hope that helps.

36 Passed Geography and 40 passed History,
of these, 22 passed both physics and History
21 passed both physics and Geography an
23 passed Geography and History. Given
that 10 of them passed all the three subjects
Find:
a. The number of Students who passed only
physics
b. The number of Students who passed
only Geography.
C. The number of student who passed
only History
The number of students who passed only physics is 6, the number of students who passed only geography is 2, and the number of students who passed only history is 5.
First, let's represent the number of students who passed each subject with the variables P, G, and H. Then, we can represent the number of students who passed multiple subjects with the variables PG, PH, and GH.
We are given the following information:
39 students passed physics (P)
36 students passed geography (G)
40 students passed history (H)
22 students passed both physics and history (PH)
21 students passed both physics and geography (PG)
23 students passed both geography and history (GH)
10 students passed all three subjects (PHG)
We can set up the following equations to represent these relationships:
P = 39
G = 36
H = 40
PH = 22
PG = 21
GH = 23
PHG = 10
We can use these equations to solve for the number of students who passed only physics (P - PH - PG + PHG), only geography (G - GH - PG + PHG), and only history (H - PH - GH + PHG).
So, the number of students who passed only physics is:
P - PH - PG + PHG = 39 - 22 - 21 + 10 = 6
The number of students who passed only geography is:
G - GH - PG + PHG = 36 - 23 - 21 + 10 = 2
The number of students who passed only history is:
H - PH - GH + PHG = 40 - 22 - 23 + 10 = 5
Thus, there are 6 students who passed only physics, 2 students who passed only geography, and 5 students who passed only history.

Step-by-step explanation:
A beaker contains 235.5 milliliters of water. If the water is equally distributed among 15 test tubes, how many milliliters will be in each tube?
Answer: 356 mil
Step-by-step explanation:
Answer:
Each tube will contain 15.7 millimeters
Step-by-step explanation:
Since 235.5 milliliters of water is to be shared among 15 test tubes then the amount of water in each test tube is:
[tex]\frac{235.5}{15} \\\\= 15.7[/tex]
Thus each tube will contain 15.7 millimeters
Here is some data showing the age and value of 12 cars.
Draw a scatter diagram in your book and state the coordinates of the point that is most likely an outlier.
Age (years) 4 6 5 4 2 8 3 3 5 7 1 5
Value (£ 000's) 46 37 52 60 74 21 65 11 67 27 86 40
(3, 11) is the coordinate of the point that is most likely an outlier
How to draw a scatter diagram?
A scatter diagram is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data
Given: The Age and Value as shown in the question
Age (years) 4 6 5 4 2 8 3 3 5 7 1 5
Value (£ 000's) 46 37 52 60 74 21 65 11 67 27 86 40
The values of Age against Value will then be plotted on a scatter plot as shown in the image attached. Note that Age will be on the horizontal while Value will be on the vertical.
Therefore, the coordinate of the point that is most likely an outlier is (3, 11). This is because it is too far from the line

Explain the reasoning
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
[tex] \frac{12}{x} = \frac{8}{6} \\ 12 = \frac{8x}{6} \\ 12 \times 6 = 8x \\ \frac{72}{8} = x \\ 9 = x[/tex]
Check
[tex] \frac{12}{x} = \frac{8}{6} \\ \\ \frac{12}{9} = \frac{8}{6} \\ \\ 1.333 = 1.333[/tex]

how many ways can you write two different letters, so that they are in alphabetical order? for example, am and iq count, but om does not.
There are 325 ways we can write two different letters so that they are in alphabetical order.
A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant (unlike permutations).
A k-combination of a set S is officially defined as a subset of S's k unique elements.
We have 25 ways to have the combo A_
Then 24 ways to have the combo B_
The number of combos = 25 * (26/ 2)
= 25 * 13
= 325 ways
