Answer:
Area of a regular decagon with a perimeter of 60 ft. = 277 squared ft
Step-by-step explanation:
Decagon has 10 sides So 60/10 = 6 (each side = 6ft )
The sum of the interior angles of a decagon is 1 440 degrees.
There are 10 equal isosceles triangles of base angles 72 degrees in a decagon
Each isosceles triangle can subdivided into 2 right-angled triangles with height h and base length = (6/2) = 3 cm and base angle 72 degrees.
Height of right-angled triangle h = 3 tan 72 ft.
Area of 1 right-angled triangle = (1/2)(3)(3 tan 72) = 13.85 squared ft
Area of decagon = 20 right-angled triangles = 277 squared ft

A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21

What is the amount of income tax in dollars and cents if a plumber makes $51,482 and has to pay a 5.5% income tax rate? $2,821.51
Answer:
$2,821.51
Step-by-step explanation:
The amount made be plumber = $51,482
rate of income tax = 5.5%
Therefore, amount of income tax in dollars and cents that would be paid by the plumber would be 5.5% of his amount made
= 5.5% of 51482
= (5.5/100)×51,482
= $2,821.51

Angle ABC is inscribed in circle p the length of PC is 12 units the arc length of a c is 68/15 pi what is the measure of angle ABC in degrees
Answer:
68°
Step-by-step explanation:
The formula for arc length when central angle is in degrees =
Arc length = 2πr × θ /360
Arc length = 68/15π
Radius = the length of PC = 12 units
Hence:
68/15π = 68π/15 = 2 × π × 12 × θ /360
68π/15 = 75.4 ×θ /360
Cross Multiply
68π × 360 = 15 × 75.4 × θ
θ = 68π × 360/15 × 75.4
= 67.998398019°
Approximately = 68°
Therefore, the measure of central angle = 68°
Answer:

answer to the nearest tenth if necessary. Figures are not drawn to scale.

Answer:
ML/OP=MK/PN since sides of similar traingle are proportional
17/60=35/PN
PN=35×60/17=123.529=123.6 or 124
The measure of the side PN is 123.5.
What are Similar Triangles?Similar triangles are those triangles which has the same shape but different size.
The length of sides and angles are proportional in similar triangles
Given that triangle KLM is similar to triangle NOP.
If two triangles are similar, then their corresponding sides will be proportional.
From the figure,
Corresponding side of LM is PO.
Corresponding side of MK is NP.
Corresponding side of LK is ON.
So LM / PO = MK / NP = LK / ON
17 / 60 = 35 / PN = LK / ON
We need the length of PN.
17 / 60 = 35 / PN
17 × PN = 60 × 35
PN = (60 × 35) / 17
PN = 123.5
Hence the measure of the side of the triangle is PN = 123.5.

Could someone help me find an equation ❤️
Answer:
-(2/3)x+4
Step-by-step explanation:
For the slope you do rise over run, since the graph intercepts the y-axis at 4 and goes down to 0 the rise is -4 and from the same point the graph "runs" 6 the rise/run is -4/6 which can be simplified to -2/3. For the y-intercept you simply find where the graph touches the y-intercept and add (or subtract if the number is negative) that to the end of the equation.

A rectangle has an area of 235.2m squared. One of the sides is 2.8m in length. work out the perimeter of the rectangle, please?
Answer:
P = 173.6 mSteps:
given:
A = 235.2 m²
S1 = 2.8 m
S2 = A/S1
S2 = 235.2/2.8
S2 = 84 m
P = 2(S1+S2)
P = 2(2.8+84)
P = 2 × 86.8
P = 173.6 m

By the property of triangle,
If the sides of triangle are unequal, then the ratio of the measures of the angles will be equal to the ratio of their opposite sides.
Following this rule,
Angle opposite to the largest side will be biggest and angle opposite to the smallest side will be smallest.
Since, LJ > KL > JK
Therefore,
∠K > ∠J > ∠L

The average human reaction time from eye to finger is 0.16 second. How is this expressed as a fraction?
Answer:
4/25 seconds
Step-by-step explanation:
the second (0.16) is in two decimal places, so divide 16 by 100
[tex]\frac{16}{100}[/tex]
