Which statement is true statement about rotation?
A. The image is smaller than the preimage.
B. The image overlaps the preimage.
C. The image is larger than the preimage
D. The image and preimage are congruent.
Answers
Answer:
The correct option is D. The image and preimage are congruent.
Step-by-step explanation:
Let us understand the this concept with the help of an example.
Consider the figure 1:
From the figure 1, it is clear that the size of image doesn't change.
Thus, option A and C are invalid.
Or we can say that, the image and preimage remain the same.
Therefore, the correct option is D. The image and preimage are congruent.

A used car dealership buys a car for $2800 and then sells it for $4500 what is the percent increase?
Answers
The percentage is the indicating hundredth of any change in quantity thus the percentage increase of cars from $2800 to $4500 is 60.72%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given question,
Buying cost of car = $2800
Selling cost of car = $4500
Percentage change = (change/original) × 100
Percentage change = [(4500 - 2800)/(2800)] × 100
Percentage change = [(1700)/2800] × 100
Percentage change = 0.607 × 100
⇒ 60.72%
Hence "The percentage is the indicating hundredth of any change in quantity thus the percentage increase of cars from $2800 to $4500 is 60.72%".

Lola takes the train from Paris to Nice. The distance between the two cities is about 921,000 meters. If the train travels at a speed of 307 kilometers per hour, how long will it take Lola to travel from Paris to Nice
Answers
Answer: It will take 1.75 minutes to travel from Paris to Nice.
Step-by-step explanation:
Since we have given that
Distance between the two cities = 921,000 meters
Since we know that
1 km = 1000 meters
[tex]1\ m=\dfrac{1}{1000}\ km\\\\921000\ m=\dfrac{921000}{1000}\ km=921\ km[/tex]
Speed at which the train travels = 307 km/hr
As we know the formula for time taken:
[tex]Time=\dfrac{Distance}{Speed}=\dfrac{921}{307}=0.029\ hours\\\\Time=0.029\times 60=1.75\ minutes[/tex]
Hence, it will take 1.75 minutes to travel from Paris to Nice.
if f(x)=-6x+12, then f^-1(x)=
Answers
Okay, so let's start with swapping all of the variables.
x = -6y + 12.
We'll start with subtracting both sides by 12. Our goal is to isolate y, and we do so by doing the inverse of the operation on each value.
Since 12 is positive, the inverse of being positive is negative. So, we shall subtract!
x - 12 = -6y + 12 - 12.
Which leaves us with x - 12 = -6y.
Since the -6 is multiplying our variable, the inverse of multiplication is division, so we shall divide both sides by -6.
[tex] \frac{x - 12}{-6} [/tex] = -6y / -6.
Which leaves us with [tex] \frac{x - 12}{-6} [/tex] = y.
Our final answer is:
[tex] f^{-1}(x) [/tex] = [tex] \frac{x - 12}{-6} [/tex].
Hopefully, this helps! =)
y = -6x + 12
Switching y and x, and then solving for y:
x = -6y + 12
6y = 12 - x
y = [tex] \frac{12- x}{6} [/tex]
Hence,
[tex] f^{-1} (x) = \frac{12- x}{6}[/tex]
Find a number whose product with 9 is the same as its sum with 56
Answers
9x must be the same as x+56:
[tex] 9x = x+56[/tex].
We substruct x from both sides:
[tex] 8x = 56[/tex]
and we divide by 8 in both sides of the equality:
[tex] x = 7[/tex]
Final answer:
The requested number is 7, which when multiplied by 9 or added to 56, gives the same result of 63.
Explanation:
To find a number whose product with 9 is the same as its sum with 56, we set up the equation x * 9 = x + 56. Solving for x, we first distribute the 9 to the x, resulting in 9x = x + 56. Next, we subtract x from both sides to get 8x = 56. Finally, we divide both sides by 8 to find that x = 7. Hence, 7 is the number we are looking for, as 7 * 9 = 63 and 7 + 56 = 63, confirming that the product and the sum yield the same result.

If you put $1000 for annual interest, the saving account would become: $1000*(100%+1.5%)= $1015
If you put $1000 for monthly interest, the saving account would become: ($1000*(100%+0.125%)= $1000*1.0151035559= $1015.10
Then, the money difference should be: $1015.10-$1015= $0.10
Cynthia besch wants to buy a rug for a room that is 1313 ft wide and 2222 ft long. she wants to leave a uniform strip of floor around the rug. she can afford to buy 112112 square feet of carpeting. what dimensions should the rug have?
Answers
Since the area is 112112 square feet, we get that (1313-x) *(2222-x) is the area of the rug which equals 112112. Multiplying it out, we get
x^2-2222x-1313x+(1313*2222)=112112. Next, we get
x^2-3535x+2917486=112112, and we subtract 112112 from both sides to get x^2-3535x+2805374=0. Using the quadratic formula, we get
(3535+-sqrt(3535^2-4*2805374))/2=either around 2332 or 1203. Since it can't be 2332 due to that 1313 is less than that and the rug cannot be negative in width, we get 1203 as the uniform width.
The dimensions of the rug are 1313-1203=around 110 as the width and 2222-1203=around 119 feet

choose the correct word to complete the following sentance: a natural number is (always, sometimes, never) a whole number
Answers
The set of natural numbers is this {1, 2, 3, 4, 5, ...} basically the set of counting numbers. Zero is not part of this set.
The set of whole numbers is {0, 1, 2, 3, 4, 5, ...} almost the same set but now zero is part of the group.
Any number in the first set is automatically part of the second. We consider the first set to be a subset of the second set. Any natural number you can think of is also a whole number. The same cannot be said the other way around. As you can see, zero is NOT a natural number. So the set of whole numbers is not a subset of the natural numbers.

Stan wants to make a rectangular garden. he has 34 ft of fencing to put around the perimeter. if the length is to be 5 ft more than the width, find the dimensions of the planned garden.
Answers
P = 34
L = W + 5
34 = 2(W + 5 + W)
34 = 2(2W + 5)
34 = 4W + 10
34 - 10 = 4W
24 = 4W
24/4 = W
6 = W <==== the width is 6 ft
L = W + 5
L = 6 + 5
L = 11 <==== the length is 11 ft
Using the concept of perimeter and given conditions, the planned garden's dimensions should be 6 feet by 11 feet with a total perimeter coverage of 34 feet.
Explanation:The problem can be solved by using the concept of perimeter in mathematics. The perimeter of a rectangle is the sum of all its sides, and given that Stan has 34 ft of fencing, this can be translated to a formula: 2*(length + width) = 34ft.
From the question, we also know that the length of the fence is 5 ft more than the width. This can also be translated into an equation: length = width + 5.
By substituting this into the earlier equation, we can find the width: 2*(width + width + 5) = 34, which simplifies to 4*width + 10 = 34. Solving this gives us width = 6 ft.
Substitute width = 6 ft into the length equation to get length = width + 5 = 6 + 5 = 11 ft. Therefore, the dimensions of the planned garden are 6 ft by 11 ft.

The solution to the inequality 2n + 5 > 1 is n > -2 after isolating the variable n and simplifying the equation.
Explanation:The solution to the inequality 2n + 5 > 1 involves some basic algebra. First, we should isolate the variable, n, on one side of the inequality. This is accomplished by subtracting 5 from both sides of the inequality which gives us: 2n > 1 - 5.
Simplifying the right side gives us 2n > -4. Then, we need to divide every term by 2 which gives us n > -4/2. Simplifying further, we find that the solution to the inequality 2n + 5 > 1 is n > -2.
