Answer:
90 degrees
Step-by-step explanation:
When we want to find the rotational symmetry of a shape, we will take the total angle measure of most shapes (360 degrees) and divide it by the number of angles that shape has. Since a square has 4 angles, thats what we will divide by and the answer we get will be the smallest angle of rotation.
360 / 4 = 90
Best of Luck!
The smallest angle of rotational symmetry for a square is 90°. A square has four sides of equal length and four angles of 90° each, which means that rotating it by any multiple of 90° will result in the same image. Thus, the smallest angle of rotational symmetry is 90°.
What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
• Triangle
• Quadrilateral
• Pentagon
• Hexagon
• Heptagon
• Octagon
• Nonagon
Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:
α = 360/n
The smallest angle of rotational symmetry for a square is 90°.
This means that the square can be rotated by 90° and still look the same.
It can also be rotated by 180° and 270° to look the same,
but the smallest angle is 90°.

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (10, - 3) and (x₂, y₂ ) = (- 4, - 9) , then

Claude's net pay for the month was $985.50.
If his gross pay is $1350.00, his net pay is what percent of the gross pay?
Hello ;)
We have :
Claude's net pay → $985.50
Claude's gross pay → $1350.00
We know that the gross pay represents 100 % of the salary.
So :
$1350.00 ⇔ 100 %
$985.50 ⇔ ? %
? = 985.5 × 100 ÷ 1350 = 73 %
Claude's net pay is 73 % of the gross pay.
:-)
Based on his net pay being $985.50 and his gross pay being $1,350.00, the net pay is 73% of the gross pay.
To find out how much of the percentage of something a variable is, you make the variable the numerator and the other measure the denominator.
In this instance that would be:
= Net pay / Gross pay x 100%
= 985.50 / 1,350 x 100%
= 73%
In conclusion, the net pay is 73% of the gross pay.

Can anyone please help me to find the area of this please
9514 1404 393
Answer:
√35 +3√7 -6 . . . square units
Step-by-step explanation:
The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.
Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.
The overall width is the sum of the given partial widths:
width = (√7 -2) + (2) = √7
Then the area of the bounding rectangle is ...
A = LW = (√5 +3)(√7) = √35 +3√7
The area of the upper right empty-space is ...
A = LW = (3)(2) = 6
Then The area of the shaded figure is ...
√35 +3√7 -6

Find the 11th term of the arithmetic sequence -5x + 6, -9x + 11, -13x + 16
Answer:
11th term is -45x+56
Answer:
a_11 = -45x + 56
Step-by-step explanation:
An arithmetic sequence has a constant difference which can be found by subtracting a term from the next term.
constant difference = d = -9x + 11 - (-5x + 6)
d = -9x + 11 + 5x - 6
d = -4x + 5
The nth term of an arithmetic sequence is
a_n = a_1 + (n - 1)d
a_11 = a_1 + (11 - 1)(-4x + 5)
a_11 = -5x + 6 + 10(-4x + 5)
a_11 = -5x + 6 - 40x + 50
a_11 = -45x + 56

Write 63 as a product of as many factors a possible. Do not use 1 as a factor.
Answer:
7 x 9 = 63 7 is a FACTOR of 63
9 is a FACTOR of 63
7 and 9 are even DIVISORS of 63
63 is a MULTIPLE of 7 and 9
63 is a PRODUCT of 7 and 9
63 is evenly DIVISIBLE by 7 or 9
Writing 63 as a product of as many factors will be: 7 × 9, 3 × 21, 9 × 7 and 21 × 3.
The factors of 63 include 1, 3, 7,9, 21 and 63.
Since we've been given the information that we should not use 1 as a factor when multiplying according to the question, then the 63 as a product of its factors will be:
3 × 21 = 63
7 × 9 = 63
9 × 7 = 63
21 × 3 = 63
