a rotation of 180 degrees maps figure A onto itself. It has
Letter A doesn't show rotational symmetry of 180 degrees.
The letter 'A' has just one vertical line of symmetry.A vertical line of symmetry is that line which runs down a picture thus dividing it into two identical halves. In other words, it's a straight standing line that divides an image or shape into two identical halves.
The rotational symmetry of a shape explains that when an object is rotated on its own axis, the form of the object looks the same. Many geometrical shapes appear to be symmetrical once they are rotated 180 degrees or with some angles, clockwise or anticlockwise. A number of the examples are square, circle, hexagon, etc.

find a formula for the nth term of the arithmetic sequence the first term is 7 and the common difference is -3
The formula for the nth term of the arithmetic sequence whose first term is 7 and the common difference is -3 is - a[n] = 10 - 3n
What is an Arithmetic progression?An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. A sequence -
a₁ , a₂, a₃ , a₄ ...... aₙ
will be an arithmetic progression if -
a₂ - a₁ = a₃ - a₂ = a₄ - a₃ = d (constant) is called common difference of A.P. and a₁ = 'a' as the first term.
Given is the the first term equal to 7 and the common difference equal to
- 3.
We can calculate the nth term of an A.P. using the formula -
a[n] = a + (n - 1)d
a[n] = 7 + (n - 1)(- 3)
a[n] = 7 - 3n + 3
a[n] = 10 - 3n
Therefore, the formula for the nth term of the arithmetic sequence whose first term is 7 and the common difference is -3 is -

Distribute property of 41×8
Using distribute property on 41×8 is 328.
What is the Distributive Property?
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
We know that,
Distributive property is A × (B + C) = AB + AC.
So, 41 × 8 is 41 × (5 + 3 ) = 41×5 + 41×3
41 × (5 + 3 ) = 205 + 123
41 × (5 + 3 ) = 328
Hence, using distribute property on 41×8 is 328.

There is a new fair coming to town this weekend. Tickets are selling for $10.99 for adults and $5.99 for kids. Each ride is $0.99 cents each. Make an equation for adults tickets and another equations for kids ticket. How much money would each spend if they each ride 5 rides?
Answer:
(a)Adult:10.99+0.99x, Kid: 5.99+0.99x
(b)Adult's Total cost = $15.94, Kid's Total cost =$10.94
Explanation:
Cost of a ride = $0.99
Let x be the number of rides.
Cost of an Adult Ticket = $10.99
An equation for adult tickets will therefore be: 10.99+0.99x
Similarly, the cost of a kid ticket =$5.99
An equation for adult tickets will therefore be: 5.99+0.99x
(b)If they ride 5 tickets each, the amount of money spent will be:
x=5 rides
Total cost for an adult=10.99+0.99(5)
=10.99+4.95
=$15.94
Total cost for a kid = 5.99+0.99(5)
=5.99+4.95
=$10.94
Find the minimum value of the parabola y = x2 − 6.
The minimum value of the parabola is y = -6
An equation of a parabola is given as
y = x²-6
We will find its minimum value using the differentiation method.
For this first we will find the derivative with respect to x and find the value of x at which the derivative becomes zero. The derivative becomes zero only when the parabola has either a maximum or minimum value. We further check whether the parabola has a minimum or maximum at that x by finding the second derivative of the parabola at that x.
So first derivative of y with respect to x is 2x.
So 2x = 0
⇒ x =0
Now take the second derivative of y with respect to x at x = 0,
Second derivative = 2 > 0 at x = 0
Here the second derivative is greater than zero at x = 0. So y has a minimum value at x = 0
The minimum value of the parabola is,
y = 0² - 6

1616 ft³
STEP-BY-STEP EXPLANATION:
We have that the formula to determine the volume of the cylinder is as follows:
[tex]V=\pi r^2\cdot h[/tex]The radius is equivalent to half the diameter, therefore the radius is equal to 3.5 ft (7/2) while the height, in this case, is equivalent to the length, so it is equal to 42 ft. Therefore, we replace each value and calculate the volume, like this:

Answer:
Yes, y=0.08x
Explanation:
The unit price can be calculated as the price divided by the number of ozs, so the unit prices are:
[tex]\frac{\text{Price}}{\text{Ounces}}=\frac{\text{ \$2.56}}{32\text{ oz}}=\text{ \$0.08 per ounce}[/tex][tex]\frac{Price}{Ounces}=\frac{\text{ \$0.48}}{6\text{ oz}}=\text{ \$0.08 per ounce}[/tex]Therefore, the unit prices are equal, so the equation that represents the relationship is:

3) Alex had 20 video games at the beginning.
2) The strategy to solve the problem backward is:
The number of games Alex has now is 16 games.
The number of games he gave to his brother is 2, so add 2 to the current number of video games, 16 + 2 = 18
Now add the games he sold, which are given as 3
18 + 3 = 21
Subtract the games he traded with Hector,i.e. 6 video games
21 - 6 = 15
This obtained number is 3/4 of his games,
3/4 of the total video games = 15
Therefore, the total video games were = (15×4)/3 = 20
4) Yes the answer makes sense.
Operations in reverse order are:
The number of video games given by Alex to hector is = 1/4 of 20 = 5
Remaining video games = 20 - 5 = 15
Number of games after adding exchanged 6 video games = 15+6 = 21
Number of games after Alex sold 3 video games = 21 -3 = 18
Number of games after Alex gave 2 to his brother = 18 - 2 = 16 video games

Step-by-step explanation:
You are in charge of planning your mother's surprise party. You have found a hall that rents for $225 and a caterer that will charge you $15 per guest. Write an inequality to calculate your total cost (T) based on the number of guests (g).
T = 15g + 225
If you have a total budget of $1000 how many guests can you
invite?
1,000 = 15g + 225
subtract 225 from both sides:
1,000 -225 = 15g + 225 - 225
775 = 15g
divide both sides by 15:
775/15 = 15g/15
g = 51.66
Because you cannot invite part of a guest round down to inviting 51 guests

The number of walnuts is double the number of pecans.
Write an equation to show how many of each nut this nut bread contain.
An equation showing how many of each nut this nut bread contains is Y = 2p + 4w + 2t.
What is an equation?An equation is a mathematical expression of equality between two variables or expressions.
Equations are shown using the equation mark, symbol, or sign (=).
The number of walnuts in the nut bread = 1/2
The number of pecan nuts = 2
The number of walnuts which is double of pecan nuts = 4 (2 x 2)
The number of other nuts = 2 since walnuts equal 1/2 of the nuts
The total number of nuts = 8 (2 pecan, 4 walnuts, and 2 others)
Let the number of nuts in the bread = Y
Let the number of walnuts, w = 4
Let the number of pecan nuts, p = 2
