Find the area of the
regular figure below:
A) 645.4 m2
B) 571.3 m2
C) 624.7 m2
D) 590.2 m2

Answer:
E) 613.9 m2
Step-by-step explanation:
sum of measures of interior angles of a polygon of n sides:
(n - 2)180
For a pentagon:
(5 - 2)180 = 3(180) = 540
measure of one interior angle of a regular pentagon:
540/5 = 108
Draw a segment from the center of the pentagon to the top vertex. Now you have a right triangle.
The triangle has a 90 deg angle where the segment in the figure meets the side of the pentagon. Let half of the side of the pentagon be x. x is a side of the right triangle.
For the 54 deg angle in the triangle, 13 m is the opposite leg, and x is the adjacent leg.
tan A = opp/adj
tan 54 = 13/x
x = 13 m/tan 54 = 9.445 m
x is half of the side of the pentagon.
2x is the side of the pentagon.
2x = 2(9.445 m) = 18.89 m
The given 13 m segment is the apothem of the pentagon.
A = nsa/2
where n = number of sides, s = length of 1 side, a = length of apothem
A = (5)(18.89 m)(13 m)/2
A = 613.9 m^2
Answer: E) 613.9 m2

Point E is located at (–5, 2). Point M is the reflection of point E across the y-axis. What is the distance between E and M?
Answer:
answer=7
Step-by-step explanation:
Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7
A dome of a building is in the form of a hemisphere from inside it was whitewashed at the cost of rupees 4989.60 if the cost of white washing is rupees 20 per meter square find the inside surface area of dome and volume of air inside the dome
Answer: [tex]249.48\ m^2; 369.168\ m^3[/tex]
Step-by-step explanation:
Given
Cost of white-washing =Rs. 4989.60
Rate =20 per meter square
So, inside area of = [tex]\dfrac{4989.60}{20}=249.48\ m^2[/tex]
The surface area of dome= [tex]4\pi\ r^2=249.48[/tex]
[tex]4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m[/tex]
The volume of air in the dome [tex]V=\frac{4}{3}\pi r^3[/tex]
[tex]V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3[/tex]

Answer:
XY=13
Step-by-step explanation:
From the triangles, you can see XY=PR
XY=(2x+3)
PR=(4x-7)
plug in the values into the equation
2x+3=4x-7
solve
-2x=-10
x=5
Don't forget to substitute x into 2x+3
2(5)+3=XY
13=XY
You are running a concession stand at a basketball game. You are selling hotdogs and sodas. Each hot dog costs $2.30 and each soda costs $1.50. At the end of the night you made a total of $110.00. You sold a total of 60 hot dogs and sodas combined. You must report the number of hot dogs sold and the number of sodas sold X is the number of hot dogs and Y is the number of sodas.
a. Create two equations to represent the situation.
b. Solve the system of equations so you get an answer for x and y.
c. What does the solution mean?
Step-by-step explanation:
2.3X + 1.5Y = 110
X= 110/2.3 - 1.5Y/2.3.....(1)
x + y = 60
x= 60-Y......(2)
so use these two equations
60-Y = 110/2.3 - 1.5Y/2.3
60-110/2.3 = 1.5Y/2.3 + Y
280/23 = 8/23 Y
Y = 35
So now sub Y into (2)
X= 60-35
X= 25

Answer:
26
Step-by-step explanation:
Let 10 be a, and 24 be b, and the undefined hypotenuse be c.
[tex]a^2 + b^2 = c^2[/tex]
[tex]10^2 + 24^2 = c^2[/tex]
100 + 576 = c
c = 676
[tex]\sqrt{100} + \sqrt{576} = \sqrt{676}[/tex]
[tex]10^2 + 24^2 = 26^2[/tex]
c = 26
The value of the undefined line is 26.

!!!!!!WILL MARK BRAINLIEST!!!!!!
Answer:
B
Step-by-step explanation:
(4/25)^1/2 and (4/25)^-1/2
Answer:
(4/25)^1/2 = 2/5
(4/25)^-1/2 = 5/2
Step-by-step explanation:
(4/25)^1/2 and (4/25)^-1/2
recall that a^1/x = x√a and a ^-1/x = 1/ x√a
Hence (4/25)^1/2
Applying the laws of indices stated above
(4/25)^1/2 = √(4/25)
Recall that √a/b = √a/√b
Hence √4/25 = √4/√25
= 2/5
(4/25)^-1/2
Applying the laws of indices stated above
(4/25)^-1/2 = 1/√(4/25)
= √(25/4)
= √25/√4
= 5/2
