find the area of the small sector
8 and 40
area=m2
(round to the neerest 100)
Answers
Answer:
22.33 m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 8 m
Angle sustained (θ) = 40°
Pi (π) = 3.14
Area of small sector (A) =?
The area of the small sector can be obtained as illustrated below:
A = θ/360 × πr²
A = 40/360 × 3.14 × 8²
A = 40/360 × 3.14 × 64
A = 22.33 m²
Therefore, the area of the small sector is 22.33 m²

missing coordinate.
Answers
9514 1404 393
Answer:
x ≈ -17.457 or 11.457
Step-by-step explanation:
The distance formula can help.
d = √((x2 -x1)² +(y2 -y1)²)
Substituting given values, we have ...
15 = √((x -(-3))² +(9 -5)²)
225 = (x +3)² +16 . . . . . . . . square both sides
209 = (x +3)² . . . . . . . . . . . subtract 16
±√209 = x +3 . . . . . . . . . take the square root
-3 ± √209 = x . . . . . . . . subtract 3
x ≈ -17.457 or 11.457
HOW TO DO THIS QUESTION
Answers
Answer:
see explanation
Step-by-step explanation:
The dot above the 5 indicates the 5 is repeating , that is
2.7555...
We require 2 equations with the repeating 5 placed after the decimal point.
let x = 2.7555,,, ( multiply both sides by 10 and 100 )
10x = 27.55... → (1)
100x = 275.55... → (2)
Subtract (1) from (2), thus eliminating the repeating 5
90x = 248 ( divide both sides by 90 )
x = [tex]\frac{248}{90}[/tex] = [tex]\frac{124}{45}[/tex]

3. Segment MN has endpoints at M(-6, -3) and N(9,7). Point Q lies on MN such that MQ:QN = 3:2.
Which of the following are the coordinates of Q? Plz I don’t want fail my sophomore year
Answers
Given:
Segment MN has endpoints at M(-6, -3) and N(9,7).
Point Q lies on MN such that MQ:QN = 3:2.
To find:
The coordinates of point Q.
Solution:
Section formula: If a point divides of line segment whose end points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in m:n, then the coordinates of that points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Segment MN has endpoints at M(-6, -3) and N(9,7) and Point Q lies on MN such that MQ:QN = 3:2. By using section formula, we get
[tex]Q=\left(\dfrac{3(9)+2(-6)}{3+2},\dfrac{3(7)+2(-3)}{3+2}\right)[/tex]
[tex]Q=\left(\dfrac{27-12}{5},\dfrac{21-6}{5}\right)[/tex]
[tex]Q=\left(\dfrac{15}{5},\dfrac{15}{5}\right)[/tex]
[tex]Q=\left(3,3\right)[/tex]
Therefore, the coordinates of point Q are (3,3).

A triangle has two sides of length 18 and 4. What is the smallest possible whole-number length for the third side?
Answers
==================================================
Explanation:
Let a = 4 and b = 18 be the two known sides of the triangle.
Let c be the remaining side
We'll use a version of the triangle inequality theorem to set up the possible range of values for c.
The range of values for c is determined by the following
b-a < c < b+a
18-4 < c < 18+4
14 < c < 22
Telling us that the third side c is between 14 and 22, excluding both endpoints. This means c = 14 and c = 22 are not allowed. If either value were to happen, then the triangle becomes a single line instead. Try it out with slips of paper.
Because c = 14 is not allowed, we must go to the next whole number up. Therefore, c = 15 is the smallest possible length for the third side, when the third side is a whole number.
If the third side wasn't a whole number, then we could have something like c = 14.1 or c = 14.01 or c = 14.001 or c = 14.0001, and so on. We could steadily get closer and closer to 14, but never actually arrive to it. In short, there is no "smallest third side". This is likely why your teacher is focusing on the whole numbers so there is a smallest value of c possible.
Extra info: As you can probably guess, the largest side possible is c = 21, which is one less than 22. Like above, this is only possible if c is a whole number.
