Answer:
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
θ = 360 - (180 + 160)
= 360 - 340
= [tex]20^{o}[/tex]
Thus,
area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]
= [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169
= 29.5079
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

Answer:
Step-by-step explanation:
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with six sides, so we will let n = 6. The sum of the interior angles in this polygon would be 180(6 – 2) = 180(4) = 720. The angle on the bottom left is a right angle because of the square indicator. We know that this is 90 degrees. If we take the sum of the angles that we know we get 593. 720 - 593 = 127. x = 127.
Answer:
x=127
Step-by-step explanation:
take 180(n-2) where n=6, and you get 180(6-2) which simplified is 180(4) = 720. The sum of all the other angles is 593. subtract 593 from 720 (720-593=127). 127 is the angle of x.
all the steps laid out:
1. 180(n-2)
2. n=6
3. 180(6-2)
4. 180(4) = 720
5. 126 + 112 + 155 + 110 + 90 = 593
6. 720 - 593 = 127
7. x=127

The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answers
Answer:
length = 12
width = 9
Step-by-step explanation:
Let w= width of rectangle
length = w + 3
2w + 2(w + 3) = 42
2w + 2w + 6 = 42
4w = 36
w = 9 ( width of rectangle)
width = 9 inches
length = 9 + 3 = 12 inches

Nathan lifted 13 boxes, each weighing 12 lb more than Steven's boxes. Steven lifted 15.
The total weight of Nathan's boxes would be the weight of 1 box times 13, because he lifts a total of 13 boxes.
S is the weight of Steven's boxes.
Steven's box + 12 lb = the weight of one of Nathan's boxes.
Then, you would multiply that number by 13 to get your answer.
Therefore, the first option is correct.
13(s + 12)
number of boxes Nathan lifted(Steven's weight + the extra pounds)

What is the slope of a line which passes through points (-7,2) and (21,-10)?
Answers
The question gives us two points, (-7,2) and (21,-10), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (2 - (- 10)) ÷ (-7 - 21)
= - ¹²/₂₈
= - ³/₇
Checking my answer:
We can use the slope we found and a point to write the equation of a line. If the line passes through both points, then we calculated the slope correctly.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y + 10 = - ³/₇ (x - 21)

Answer:
Here’s the answer:
Step-by-step explanation:
The sum of the four numbers divided by 4 is equal to the mean.
the sum/4 = mean
(12 + 50 + 48 + n)/4 = 30
(110 + n)/4 = 30
(110 + n) = 30 × 4
(110 + n) = 120
n = 120 - 110
n = 10

Answers
Answer:
- 11
Step-by-step explanation:
let the number be n then 3 times the number is 3n and the opposite is - n
3n + 44 = - n ( add n to both sides )
4n + 44 = 0 ( subtract 44 from both sides )
4n = - 44 ( divide both sides by 4 )
n = - 11
The required number is - 11
