Thanom has a roll of paper consisting of a very long sheet of thin paper tightly rolled around a cylindrical tube, forming the shape indicated in the diagram.
Initially, the diameter of the roll is 12cm and the diameter of the tube is 4cm.
After Thanom uses half of the paper, the diameter of the remaining roll is closest to
Answer:
8 if including the tube and 4 if just counting the roll of toilet paper itself.
Step-by-step explanation:
Well like the question says the diameter of the toilet paper is 12 cm full both including the toilet paper and the tube. But we are also told the tube has a Diameter of 4. Taking this into consideration we both know that the tube will never get smaller but we do know the roll will decrease in size by half so while keeping the diameter of the tube at 4 we evenly remove half of the other 2 and we are left with a diameter of 2 / 4 / 2 in which giving us a total diameter of 8 therefore the diameter now being 8. (pls let me know if im wrong though i doubt i am)

the sum of the length of a side of two squares is 18cm and the sum of their areas is 212 cm^2. find the length of a side of the smaller square
Step-by-step explanation:
lengtha + b = 18cm
a = 18 - b
Areaa² + b² = 212cm²
(18-b)² + b² = 212
324 - 36b + b² + b² = 212
2b² - 36b + 112 = 0
b² - 18b + 56 = 0
b² - 4b - 14b + 56 = 0
b(b-4) -14(b - 4) = 0
(b-4) (b-14) = 0
b-4 = 0 OR. b-14 = 0
b = 4 cm b = 14 cm
so 4cm < 14cm
so , length of a side of the smaller square is 4cm .......
And , large square's = 14cm .....
Answer:
square one sides = 14, 14
square 2 sides = 4, 4
14 + 4 = 18
14 x 14 + 4 x 4 = 212
Step-by-step explanation:
14 x 14 + 4 x 4
this is the area of the 2 being added
the sides lengths are 14 and 4

Answer:
Step-by-step explanation:
n(U)=100%
n(S)=70%
n(W)=15%
n(S union w compliment)=20%
n(s intersection W)=?
n(u)=n(s)+ n(w)+ n(s union w compliment)- n(s intersection w)
or 100%=70% +15%+ 20% - n( s intersection w)
or 100%= 95%- n(s intersection w)
or 100%-95%=n(s intersection w)
or 5%= n( s intersection w)
now;
n(only w)=n(w)- n(s intersection w)
=15%- 5%
=10%
10%of people only like winter season.
i think the question is to find people who only like winter season.
if not then ans is 15% according to question.
a) The illustration of the given information in a Venn diagram is attached.
b) The percentage of people who liked both seasons is 45%.
c) If 180 people liked the summer season only, proportionately, the number of people who liked the winter season only is 300.
How the Venn diagram is illustrated:The Venn diagram, which shows similarities and contrasts, can be illustrated based on the given percentages.
Percentages are one of the ways to depict proportions, which are the equation of two ratios.
The percentage of survey people who liked the summer season = 60%
The percentage of survey people who liked the winter season = 70%
The percentage of survey people who liked none of the seasons = 15%
The percentage of participants who liked one of the seasons = 85% (100% - 15%)
The total percentage of survey people who liked either summer or winter = 130% (60% + 70%)
b) The percentage of survey people who liked both seasons = 45% (130% - 85%)
The percentage that liked only summer = 15% (60% - 45%)
The percentage that liked only winter = 25% (70% - 45%)
c) 180 people liked summer only
180 = 15%
Proportionately, if 180 = 15% of the people, the total number of people = 1,200 (180/15%)
The number of people who liked winter season only = 300 (1,200 x 25%)

Figure B is a scaled copy of Figure A.
What is the scale factor from Figure A to Figure B?
Answer: x = 60°
Step-by-step explanation:
We know a circle is equal to 360°, so we can subtract from 360° to find x using vertical angles and other given details.
Vertical (opposite) angles are equal to each other. This is why, for example, we know AGE and FGC are both 30°.
See attached for a breakdown of the angles.
360° - 30° - 30° - 90° - 90° = 2x
120° = 2x
60° = x
Answer:
x = 60°
Step-by-step explanation:
Hello!
The sum of angles on a line is 180°.
Given that Angle G is 90°, the other measure on Line DB would also be 90°. The missing angle next to x can be called y.
x° + y° = 90°Angle YThe Angle y can be calculated by using the Vertical Angles Theorem. The theorem states that if two non-adjacent angles are formed by the intersection of two lines, the measures of the angles are congruent.
This means that the measure of Angle y is 30°, as the 30° angle and y are non-adjacent and are formed by the intersection of lines AC and EF.
Angle XWe can now solve for x by plugging in 30° for y in the equation.
x° + y° = 90°x° + 30° = 90°x° = 60°The value of x is 60°.

Is Figure BBB a scale copy of Figure AAA?
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

ANYONE PLEASE HELP!!
Answer:
A
Step-by-step explanation:
Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line. Look at angle 8. It is the bottom left angle in the group of 4 angles around it. If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.
You can do the same thing taking angle 8 down to angle 12.

Is Figure B a scale copy of Figure A?
Answer: (A) Yes
Step-by-step explanation:
Let us look at the side lengths. When we are talking about scale copies, the lengths should stay proportionate from the original shape to the copy.
Both of the figures are triangles. I will be looking at the length of their legs. Figure A has leg lengths of 4 and 3. Figure B has leg lengths of 8 and 6, respectively.
This means Figure B is a scale copy of Figure A because 8/4=2 and 6/3=2. These mean the proportions stayed similar.

Is Figure B a scale copy of Figure A?
Yes, the Figure B is a scale copy of Figure A.
Given that are two figures we need to see if the Figure B a scale copy of Figure A or not.
To determine if Figure B is a scale copy of Figure A, we need to compare the two figures and check if they have the same shape but differ in size. A scale copy means that Figure B is an enlarged or reduced version of Figure A, but the proportions and shape of the two figures remain the same.
We see the side lengths of Figure A are: 6 units, 3 units, 3 units, 3 units, 6 units.
And that of Figure B are: 2 units, 1 unit, 1 unit, 1 unit, 2 units.
Taking the ratio = 6/2 = 3/1 = 3/1 = 3/1 = 6/2 = 3
So, it is clear that the side lengths are in equal proportion.
Hence the Figure B is a scale copy of Figure A.
