Answer:
11.16in^2
Step-by-step explanation:
Area of a sector = theta/360 * πr²
Area of a sector = 80/360 * 3.14*4²
Area of a sector = 8/36 * 50.24
Area of a sector = 401.92/36
Area of a sector = 11.16in^2
Hence the Area of the sector is 11.16in^2
Answer:
11.16 in²

Geometry Angle of elevation/depression
Answer:
m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]
= 49.88°

9514 1404 393
Answer:
39 units
Step-by-step explanation:
The angle markings tell you this is an equilateral triangle, so all sides are the same length.
10x -11 = 2x +29
8x = 40
x = 5
Then the side length is ...
2x +29 = 2·5 +29 = 39
The length of side KL is 39 units.
The dimensions of a rectangular community garden are 47 ft by 27 ft. The gardeners plan to divide the garden into equal-sized square plots. What is the greatest possible side length of each square plot? Use pencil and paper. How many square plots will there be with this side length? What will be the total area of the square plots? Explain how you can use the total area to check your work.
Answer:
the greatest possible length of each square plot is 1 ft.
1,269 square plots
Step-by-step explanation:
Since the plots are going to be squares then the width and length need to be the same. This means that the largest size of these plots would be calculated as the largest common divisor of the length and width of the garden. In this scenario, since 47 only has two divisors 1 and 47, and 27 is not divisible by 47 then the GCD of these two numbers would be 1. Meaning that the greatest possible length of each square plot is 1 ft.
To calculate the total number of plots needed we divide the square footage of the garden by the square footage of each individual plot like so...
47 * 27 = 1,269 sq. ft.
1 * 1 = 1 sq. ft.
1,269 / 1 = 1,269 plots
Finally, we see that we need a total of 1,269 square plots to cover that same area of the garden.
Find the value of x.
2x
120
70
A. 70
B. 35
C. 25
D. 55
Answer:
Step-by-step explanation:
120 = 2x + 70
120 - 70 = 2x + 70 - 70
50 = 2x
50/2 = 2x/2
x = 25

Brainliest??
Answer:
(-4 , 3)
Step-by-step explanation:
The y-axis is the vertical axis/line out of the two perpendicular lines.
Vertical line/axis (y-axis)= │
Horizontal line/axis (x-axis)= ___
When you reflect Point A, it will be reflected across the vertical line (y-axis). This means that the point will be on the left side in Quadrant II (- , +).

A scooter costs $160. A bicycle costs 20% more than the scooter. How much does the bicycle cost? ?
Answer:
$192
Step-by-step explanation:
160 = 100% or 1.00
20% = 0.2 + 1.00
= 1.20
160 x 1.20 = $192
Answer:
$192
Step-by-step explanation:
$160 + 20% = $192

I’m timed plsss answer correctly I’ll mark u brainliest
Answer:
[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

Simplify: 10x+2x-3= 9
A. x=-1
B. x=-2
C. x=1
D. x=2
Answer:
C. x = 1
Step-by-step explanation:
Combine like terms
10 + 2 − 3 = 9
12 − 3 = 9
Add 3 to both sides of the equation
12 − 3 + 3 = 9 + 3
Add the numbers
12 = 9 + 3
12 = 12
[tex]\frac{12x}{12} = \frac{12}{12}[/tex]
Cancel terms that are in both the numerator and denominator
[tex]x = \frac{12}{12}[/tex]
Divide the numbers
x = 1
Therefore the correct answer is C. x = 1
Answer:
C. x = 1
