Answer:
since there are 18 of these isosceles triangles in the polygon, then multiply this by 18 to get area of the polygon with 18 sides is equal to 28.56497087 square units. you can round this to as many desimal digits as required. each of those little triangle with a vertex angle of 20 degrees is an isosceles triangle.
One person takes up about 2.5 square feet of space. Use this value to estimate how many people can fit
in an area that is 20 feet wide and 25 feet long.
An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.

Answer:
9 ft
Step-by-step explanation:
its volume is equal to the area by height;
(2.5 x 3)h = 67.5
h = 9ft
Given:
Volume of triangular prism is 67.5 cubic feet
Height of triangular prism is 3 feet
Base width of triangular prism is 5 feet
Length of triangular prism is 't'
To find:
Value of 't'
Steps:
The formula for volume of triangular prism is,
volume of triangular prism = [tex]\frac{1}{2}[/tex] × Width × Height × Length
67.5 = [tex]\frac{1}{2}[/tex] × 5 × 3 × t
67.5 = [tex]\frac{1}{2}[/tex] × 15 × t
[tex]\frac{67.5}{15} = \frac{t}{2}[/tex]
[tex]4.5 = \frac{t}{2}[/tex]
[tex]4.5 * 2 = t[/tex]
[tex]9 = t[/tex]
[tex]t = 9[/tex]
Therefore the value of 't' is D) 9 feet

""solve triangle ABC using the given information round triangle measures to the nearest degree and side measure to the nearest tenth
9514 1404 393
Answer:
a) A = 73°, C = 59°, a = 16.7
b) A = 11°, C = 121°, a = 3.3
Step-by-step explanation:
The Law of Sines can be used to find angle C. Then the sum of angles in the triangle can be used to find angle A. The length of 'a' can be found either from the Law of Sines or the Law of Cosines at that point.
The given angle is opposite the shorter of the two given sides, so there are two possible solutions.
Acute triangle solution
The Law of Sines gives the relation ...
sin(C)/c = sin(B)/b
sin(C) = (c/b)sin(B)
C = arcsin(c/b·sin(B)) = arcsin(15/13·sin(48°)) ≈ 59°
Then angle A is 132° -59° = 73°, and side 'a' is ...
a = 13·sin(A)/sin(B) = 13·sin(73°)/sin(48°) ≈ 16.7
__
Obtuse triangle solution
The other value of arcsin(15/13·sin(48°)) is used:
C ≈ 121° ⇒ A = 11°
a = 13·sin(11°)/sin(48°) ≈ 3.3
__
The two solutions are ...
A = 73°, C = 59°, a = 16.7
A = 11°, C = 121°, a = 3.3
We note that the drawing is of an acute triangle, so that solution may be the one that is preferred.

A salesman earend a $325 salery this month. His total sales were $700. If the salesman earend a total of $360. What was his commission rate?
Answer:
Commission rate= 5% of sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $325
Monthly salary= $360
Sales= $700
First, we need to calculate the commissions:
Commission= monthly salary - fixed salary
Commission= 360 - 325
Commission= $35
Now, the commission rate:
Commission= commission rate* sales
35 = commission rate*700
0.05= commission rate
commission rate= 5% of sales
Consider best strategy to solve the problem. If 9 inches are equal to 27 feet on a map how many feet are equal to three inches
Answer:
9
Step-by-step explanation:
If 9 inches equal 27 what you would do is divide in order to find how much feet would be in 1 inch. So:
9/27= 3 feet
Then to find how much feet are equal to 3 inches you just multiply that by 3. So your answer is 9 feet.
Overall the work should look like
9 inches= 27 feet
9/9 inches= 27/9 feet
1 inch = 3 feet
3 inches x 3 feet
= 9

Answer:
10 1/2 sticks, or 11 sticks with half a stick left over.
Step-by-step explanation:
If every student (and there are 14 students) needs 3/4 stick of butter, the equation is 3/4 x 14 = 10 1/2

Jaden cut a square sheet of paper in half along a diagonal to make two equal
triangles. Each triangle has an area of 0.08 square units. What is the length,
in units, of one side of the square?
The length of one side of the square is approximately 0.4 units.
Let's assume that the side length of the square is "s" units.
When the square sheet of paper is cut in half along the diagonal, it forms two equal right-angled triangles. The area of each triangle is given as 0.08 square units.
The formula for the area of a right-angled triangle is:
Area = (1/2) * base * height
Since the triangles are equal, we can write:
0.08 = (1/2) * base * height
Now, let's find the base and height of one of the triangles. Since the triangle is a right-angled triangle, the base and height are the legs of the triangle.
Let's assume the base and height of one triangle are "b" and "h," respectively.
0.08 = (1/2) * b * h
We are given that the area of each triangle is 0.08 square units, so we can write:
0.08 = (1/2) * s * s
Now, we can solve for "s":
[tex]s^2 = 0.08 * 2\\s^2 = 0.16[/tex]
Take the square root of both sides:
[tex]s = \sqrt{0.16}\\s \approx 0.4[/tex]
So, the length of one side of the square is approximately 0.4 units.

Michael is saving to buy his senior ring. The base cost of the ring is $280. There are also upgrades he can purchase for the ring. If he saves $35 each month, Which solution represents how many months it will take Micheal before he can purchase his ring?
A.x<_8
B.x_>8
C.x<8
D.x>8
Answer:
B
Step-by-step explanation:
Assuming that he doesn't buy any upgrades it will take 280/35 = 8 months to save enough money to buy the ring. Taking the possibility that he may buy an upgrade too we can say that it will take 8 months or more to buy the ring.
A plane is flying at an altitude of 17,000 feet. The angle of depression from the plane to the airport on the ground is 21°. What is the distance between the plane and the airport to the nearest 10th of a foot
Answer:
47,433.0 feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Height of the plane = opposite = 17000feet
distance between the plane and the airport = hypotenuse = x
Angle of depression = 21 degrees
Since Sin theta = opp/hyp
Sin 21 = 17000/x
x = 17000/sin21
x = 17000/0.3584
x = 47,433.0
Hence the distance between the plane and the airport to the nearest 10th of a foot is 47,433.0 feet
