Please help! If you help with this please do my other questions!! (They are very similar!)
Answer: See in the explanation, screenshot attached
Step-by-step explanation:
SQUARE QRTS
Step 1: Label all of the coordinates
Step 2: Find the coordinates of the points
Q: (-2, 1)
R: (2, 1)
T: (-2, -2)
S: (2, -2)
Step 3: Know what it means to dilate
To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).
Step 4: Dilate by a scale factor of 2--multiply by 2
*x stands for the x coordinate, and y stands for the y coordinate*
Q: -2, 1
x: -2x2= -4
y: 1x2= 2
[Dilated] Q: -4, 2
R: 2, 1
x :2x2= 4
y: 1x2= 2
[Dilated] R: 4, 2
T: -2, -2
x: -2x2= -4
y: -2x2=-4
[Dilated] T: -4, -4
S: 2, -2
x: 2x2= 4
y: -2x2= -4
[Dilated] S: 4, -4
Step 5: Plot the new pairs
(See screenshot)
SQUARE ABCD
Step 1: Label all the coordinates
Step 2: Find the coordinate pairs of the points
A: -3, 3
B: 3, 3
C: 3, -3
D: -3, -3
Step 3: Remember what it means to dilate
(See 1st explanation)
Step 4: Dilate by a scale factor of 1/3
**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**
A: -3, 3
x: -3x1/3= -1
y: 3x1/3= 1
[Dilated] A: -1, 1
B: 3, 3
x: 3x1/3 = 1
y: 3x1/3= 1
[Dilated] B; 1, 1
C: 3, -3
x: 3x1/3= 1
y: -3x1/3= -1
[Dilated] C: 1, -1
D: -3, -3
x: -3x1/3= -1
y: -3x1/3= -1
[Dilated] D: -1, -1
Step 5: Plot the new pairs

HELP ASAPPPPPPPPPPPPPPPPPPPPPPPPP
Answer: 7/15
Step-by-step explanation:
2/3 - 1/5
Find the LEAST COMMON DENOMINATOR for 3 and 5. (These are the bottom numbers of your fractions!)
The least common denominator for 3 and 5 is 15.
Look at it this way.
Multiply 3 by 1, 2, 3, 4, 5:
3, 6, 9, 12, 15
Multiply 5 by 1, 2, 3:
5, 10, 15
Both of them match at 15! This is your least common denominator.
Now, let's go back.
2/3 - 1/5
Since you want 15 on the bottom, multiply 2/3 by 5/5.
2 x 5 = 10
3 x 5 = 15
Now we have: 10/15
We also want 15 on the bottom of 1/5. Multiply by 3/3.
1 x 3 = 3
5 x 3 = 15
Now we have: 3/15
Finally, you can solve the problem!
10/15 - 3/15 = ?
Your answer is: 7/15.

the difference between solving for surface area and solving for volume
Answer: The Surface Area is a sum total of Area of the planes that form a surface/shape while Volume is the space enclosed within a figure/shape/surface.
The Surface Area is a 2-Dimensional concept with units m², cm² or mm² where as Volume is a 3-Dimensional concept with m³, cm³ or mm³ as units.
PLEASE HELP QUICKLY!
Answer:
Just see the explanation and you will understand
Step-by-step explanation:
To find the area of the fountain, we need to add up the areas of the two semicircles and the quarter circle: Area = πr^2/2 + πr^2/2 + πr^2/4 Area = (5π^2/2 + 5π^2/2 + π^2/4)/π^2 Area = 21/4 Using a calculator, we can approximate this as about 5.25 square feet.

Pls, help! A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 3. Find the probability of not rolling a number less than 3.
1/3; 2/3
1/2; 1/2
5/6; 1/2
1/6; 5/6
Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

( True / False ) Force is used in aristocracy government.
If yes, how?
If no, why?
Answer:
True
Step-by-step explanation:
Looking at this topic generally force is used, if we look at the different countries across Europe at the beginning of civilization, there is lot of usage of force by the Aristocratic Governments. Even though it was prominent in Europe, there were also traces of it during the rule of Shang and Zhou dynasties of China. To support the citizens force is required, in the ancient times, use of force to make citizens obey the laws is a common practice. Nowadays in these countries the elite members who control the country reap the benefit and use of force is just to get themselves the money. Nowadays its all about Money.
False, because in aristocracy you are not forced to participate in the government.

The height of the dead tree is 16 feet
The direction in which the tree should fall is Northeast, Northwest, Southeast, Southwest.
How to solveFrom the given question, since the ray is straight, AC is parallel to DF
Meanwhile triangles ABC and DEF are right angles,
AB/DE =BC/EF
AB/6 = 8/3
AB= 16 feet.
Thus, the height of the tree is 16 feet.
Since 16 ft> 15ft> 14ft> 13ft> 12ft
Therefore, the direction which the tree is falling is Northeast, Northwest, Southeast, Southwest.

Find the area of this trapezoid. please help
Answer:
triangle on the left: 6 sq ft. triangle on the right: 28 sq ft. rectangle: 128. altogether, 162 sq ft. the trapezoid is about 61.6.
Step-by-step explanation:
for the rectangle the formula is bxh (base x height). for a triangle, it is bxh/2, or base times height divided by 2. for a trapezoid, it is b1+b2 x h / 2, or base 1 (bottom) plus base 2 (top) times height, take all of that and divide by 2.
