The numerical length of RS is 16.
Given, Point R is on line segment QS.
A line segment in geometry has two different points on it that define its boundaries. A stretch of a line that connects two locations is frequently referred to as a line segment. A line has no ends and can continue indefinitely in either direction, which is how it differs from a line segment.
QR = 4 , QS = 4x and RS = 5x ₋ 9
we know that, QS ₊ RS = QR
⇒ RS = QR ₋ QS
⇒ 5x ₋ 9 = 4x ₋ 4
unknown items move to the left of the equal sign and known items move to the right of the equal sign.
5x ₋ 4x = 9 ₋ 4
x = 5
therefore, RS = 5x ₋ 9
= 5(5) ₋ 9
= 25 ₋ 9
= 16
hence we get the length of RS as 16.

Given AB where A (3,4) and B (-1,-2), translate left 2 and up 1, then rotate 90 degrees clockwise about the point C(1,3). Graph and list the coordinates of A"B"
pls help urgently!!!!
The coordinates of the ends of the line segment A''B'' are A''(x, y) = (3, 3) and B''(x, y) = (- 1, 7), respectively. The graph of the line segment is attached aside.
What are the coordinates of the image of a line segment?
In this problem we must find the coordinates of a new line segment, generated after making translations and rotation, two kinds of rigid transformations. First, determine the coordinates of the ends of the line segments by translation formula:
A'(x, y) = (3, 4) + (- 2, 1)
A'(x, y) = (1, 5)
B'(x, y) = (- 1, - 2) + (- 2, 1)
B'(x, y) = (- 3, 1)
Second, determine the coordinates of the ends of the line segment by using the rotation formula:
A''(x, y) = O(x, y) + ((A'x - Ox) · cos θ - (A'y - Oy) · sin θ, (A'x - Ox) · sin θ + (A'y - Oy) · cos θ)
A''(x, y) = (1, 3) + ((1 - 1) · cos (- 90°) - (5 - 3) · sin (- 90°), (1 - 1) · sin (- 90°) + (5 - 3) · cos (- 90))
A''(x, y) = (1, 3) + (2, 0)
A''(x, y) = (3, 3)
B''(x, y) = O(x, y) + ((B'x - Ox) · cos θ - (B'y - Oy) · sin θ, (B'x - Ox) · sin θ + (B'y - Oy) · cos θ)
B''(x, y) = (1, 3) + ((- 3 - 1) · cos (- 90°) - (1 - 3) · sin (- 90°), (- 3 - 1) · sin (- 90°) + (1 - 3) · cos (- 90))
B''(x, y) = (1, 3) + (- 2, 4)
B''(x, y) = (- 1, 7)
The coordinates of the ends of the line segment A''B'' are A''(x, y) = (3, 3) and B''(x, y) = (- 1, 7), respectively. The graph of the line segment is attached aside.

Becky feeds her cat 55 g of cat food per day. About how many ounces of cat food will she feed her cat in 4 weeks? {1 oz ≈ 28.3 g}
13.6 oz
54.4 oz
1.9 oz
220 oz
The ounces of cat food she will feed her cat in 4 weeks is 54.4 oz
How to determine the number of feet?The given parameters are
1 oz = 28.3 g
1 day = 55 g
For 4 weeks, the amount would be
1 * 7 * 4 days = 55 g * 4
So, we have
28 days = 1540 g
Rewrite as
4 weeks =1540 g
Recall that 1 oz = 28.3 g
So, we have:
4 weeks = 54.4 oz
Hence, the ounces of cat food will she feed her cat in 4 weeks is 54.4 oz

Find the distance between the pair of points. Round to the nearest tenth, if necessary. (-4,-5) (0,5)
The distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 10 units.
We are given the two points:
( − 4 , - 5 ) and ( 0 , 5 )
We need to find the distance between the two points.
The formula for distance is given as:
Distance = √ (x₂ - x₁)² + (y₂ - y₁)²
Substituting the values, we get that:
Distance = √ ( 0 + 4 )² + ( 5 + 5)²
Distance = √ ( 4 )² + ( 10 )²
Distance = √ 16 + 100
Distance = √ 116

Find the coordinates of the centroid of the triangle with the given vertices. (Lesson 5-2)
R(-6,4), S(-2,-2), T(2,4)
The triangle with vertices located at R(-6 , 4), S(-2 , -2), T(2 , 4) has its centroid located at (-2 , 2).
The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.
To get the centroid of a triangle, use the formula given by:
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
where C is the centroid of the triangle located at (x , y)
x1, x2, and x3 are the x-coordinate of the vertices of the triangle
y1, y2, and y3 are the y-coordinate of the vertices of the triangle
Let Point 1(x1 , y1) = R(-6 , 4)
Point 2(x2 , y2) = S(-2 , -2)
Point 3(x3 , y3) = T(2 , 4)
Plug in the values in the formula.
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
C(x ,y) = [(-6 + -2 + 2)/3 , (4 + -2 + 4)/3]

A yacht is sailed from A to B on a bearing of 196ºT. To sail from B directly back to A the true bearing would be:
If yacht is sailed from A to B on a bearing of 196ºT, the true bearing to sail directly back to point A from point B is 16° T.
To determine the true bearing from point B back to point A, we need to consider the relationship between true bearings and the reciprocal direction.
Given that the yacht is sailed from point A to point B on a bearing of 196° T (True), the reciprocal direction would be the opposite direction, 180° away on the compass.
Thus, to sail directly back to point A from point B, we would need to subtract 180° from the reciprocal direction.
Reciprocal direction - 180°

When two or more lines meet at a common point it is known as intersecting lines.
According to the question we have been given that there are two lines who are intersection at a point. And we have been given measure of two angles.
Let the first angle be given as ∠A and the second angle be given as ∠B.
The measure of angles given to us are :
∠A = 3x° and ∠B = (80 - x)°
We know that when two lines intersect then the vertically opposite angles are equal, that is
∠A = ∠B
Putting the required values we get
3x° = 80° - x°
4x° = 80°
x = 20°
Hence the value of x = 20°. Thus the measure of ∠A = 60° and ∠B = 60°
