Answer = 3.14 * 40 = 125.6m^2
Step-by-step explanation:
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = \pi R^2 - \pi r^2 - This can be the expression
B) pi = 3.14
= pi (R^2-r^2)
= pi (11^2-9^2)
= pi (121-81)
= pi *40
That was the simplified expression

Ghlj and gstu are both parallelograms why is angle L= angle T
Answers
Answer: By the parallelogram angle theorem, opposite angles of a parallelogram are congruent. Therefore, angle T must be congruent to angle G, and angle G must be congruent to angle L. By the transitive property of congruence, angle T is congruent to angle L.
Step-by-step explanation: This is the sample response on Edge.
Both parallelograms are <L ≅ < T
Because, by the parallelogram angle theorem, opposite angles of a parallelogram are congruent.
Given parallelograms, GHLJ and GSTU such the parallelogram GSTU is inscribed inside parallelogram GHLJ with angle G coinciding on the two parallelograms.
Therefore, angle T must be congruent to angle G, and angle G must be congruent to angle L. By the transitive property of congruence, angle T is congruent to angle L.
Therefore, ∠L ≅ ∠T
The parallelogramA parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees.
Parallelograms are shapes that have four sides with two pairs of sides that are parallel. The four shapes that meet the requirements of a parallelogram are square, rectangle, rhombus, and rhomboid.
Four types of parallelogramsRectangles, rhombus, and squares are parallelograms. A trapezoid has at least one pair of parallel sides. The parallel sides are called the bases and the non-parallel sides are called the legs. There are three types of trapezoid - isosceles, right-angled, and scalene trapezoids.

Reginald is distributing n boxes of paper to the copy rooms in an office building. If he places 6 boxes of paper in each copy room, there are 7 boxes left over. In order to place 7 boxes of paper in each room, he will need 2 more boxes. How many copy rooms are in the office building?
Answers
Answer:
The total number of copy rooms in the building is 9.
Step-by-step explanation:
With the given information we can compute the total number of copy rooms (let's call them r) and the boxes of paper Reginald has to distribute among them (already named n).
From the first arrangement we can see that if reginald gives 6 boxes of paper to each room, he will still have 7 boxes. We can write this as:
[tex]n = 6 \cdot r + 7[/tex]
From the second arrangement we can see that if reginald gives 7 boxes of paper to each room, he would still need 2 boxes. We can write this as:
[tex]n = 7 \cdot r - 2[/tex]
From the above, we have a 2x2 system of equations, which can be solved by any method. In this case, we can use equalization to easily find the number of rooms. From the 2 relations we can write:
[tex]6 \cdot r + 7 = 7 \cdot r - 2[/tex]
Puting known and unknowns on opposite sides, we get:
[tex]7+2 = (7-6) \cdot r [/tex]
Solving we get:
[tex]9 = r[/tex]
Therefor the total number of rooms is 9.
Pluging this solution into any of the 2 equations, we can obtain that the number of boxes of paper is 61.
As a reference, the following link is useful:
https://en.wikipedia.org/wiki/System_of_linear_equations
The number of boxes of paper exists at 61.
How to find the copy rooms in the office building?The whole number of copy rooms as r and the boxes of paper Reginald has to distribute among them (already named [tex]$\mathbf{n}$[/tex] ).
Reginald gives 6 boxes of paper to each room, he will always have 7 boxes. We can write this as:
[tex]$n=6 \cdot r+7$$[/tex]
Reginald shows 7 boxes of paper to each room, he would always require 2 boxes. We can write this as:
[tex]$n=7 \cdot r-2$$[/tex]
From the above equation, we have a [tex]$2 \times 2$[/tex] system of equations, which can be solved in any form. In this issue, we can utilize equalization to easily find the number of rooms.
From the 2 relations we can write:
[tex]$6 \cdot r+7=7 \cdot r-2$[/tex]
Putting known and unknowns on opposite sides, we get:
[tex]$7+2=(7-6) \cdot r$$[/tex]
Solving we get:
[tex]$9=r$$[/tex]
Thus the total number of rooms exists at 9.
Plugging this solution into any of the 2 equations, then we get

H. 6x - 9 < -21
_
J. -3x -15 < -27

Answers
The number line represents the solution to the inequality -2x + 7 > 8, and the solution is x < -0.5.
Explanation:The filled circle and the arrow pointing left on the number line indicate that the solution to the inequality is to the left of -2.
The inequality that represents this solution is -2x + 7 > 8.
To solve this inequality, we can subtract 7 from both sides to isolate the x variable.
This gives us -2x > 1. Finally, we divide both sides of the inequality by -2, remembering that when we divide by a negative number, the inequality sign flips.
So, the solution to the inequality is x < -0.5.
Thus, Correct option for the given number line is F. -2x + 7 > 8.
Final answer:
The number line indicates the solution to the inequality H. 6x - 9 < -21, where x < -2, including -2 (since the circle is filled). The solution matches the given number line plot.
Explanation:
The number line given indicates the solution to an inequality that includes all numbers to the left of – the filled circle on –2, which means –2 is included in the solution set. This represents an inequality that is of the form x ≤ a where a is –2 in this case. Now let's analyze each of the provided inequalities.
F. -2x + 7 > 8: Solving this we get –x > 1 or x < –1, which does not match the plot.
G. 7x + 11 < 4: Solving this inequality we get x < –1, which also is not a match.
H. 6x - 9 < -21: Resolving this inequality leads to x < –2, which matches the number line.
J. -3x - 15 < -27: Solving this we get x > 4, which is incorrect as per the number line plot.
Therefore, the correct inequality is H. 6x - 9 < -21.

Subtract 8 from both sides. This leaves you with
sqrt(x-2) = x-8. Square both sides to get rid of the sqrt,
leaving x-2=(x-8)^2
expanding gives x-2=x^2-16x+64
subtract x from both sides leaves
-2=x^2-17x+64
add 2 to both sides
x^2-17x+66=0
this cannot be factored, however, there are other techniques.
Completing the square is a bit annoying, so I will use the quadratic formula, to give the answer.

(x+ 3)2 + (y - 7)2 = 200
(x - 6)2 + (y + 14)2 = 142
D)
(x+6)2 + (y- 14)2 = 142
Answers
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
To obtain this form use the method of completing the square.
Given
x² + y² - 6x + 14y = 142
Collect the x and y terms together
x² - 6x + y² + 14y = 142
add (half the coefficient of both x and y terms )² to both sides
x² + 2(- 3)x + 9 + y² + 2(7)y + 49 = 142 + 9 + 49
(x - 3)² + (y + 7)² = 200 → A

Answer:
f(x) = -x² + 2x + 4Step-by-step explanation:
We have quadratic functions f(x) = ax² + bx + c.
c - y-intercept
If a > 0, then a parabola opens up and has a minimum in a vertex.
If a < 0, then a parabola opens down and has a maximum in a vertex.
The function has maximum and y-intercept of 4:
a < 0 and c = 4
The graph of the function which will have a maximum and a y-intercept of 4 is C. f(x) = x² + 2x + 4.
What is y Intercept?y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.
Given are four functions.
We have to find the function which has a y intercept of 4.
This means that substitute x = 0 and then find the value of f(x).
A. f(x) = 4x² + 6x - 1
When x = 0, f(x) = -1 ≠ 4
B. f(x) = -4x² + 8x - 5
When x = 0, f(x) = -5 ≠ 4
C. f(x) = x² + 2x + 4
When x = 0, f(x) = 4
D. f(x) = x² + 4x - 4
When x = 0, f(x) = -4
Hence the function which has a y intercept of 4 is C. f(x) = x² + 2x + 4.

Answer:
Answer is 50 meters
Step-by-step explanation:
Solution:
Height of the building (h)= 90 meters.
Time taken by the ball to reach the ground (t) = 3 seconds
According to the statement;
h = kt²
90=k(3)²
90=k(9)
90=9k
Divide both the sides by 9
k=10
h=kt²
Put the value time (t)=2 in the equation
h=10(2)²
h=10(4)
h=40 meters
Distance from the ground = 90 - 40
