Answer:
8.0meters
Step-by-step explanation:
Given data
Area of cirlce= 201 square meters
The expression for the area is
A=πr^2
Substitute our area
201= 3.14*r^2
r^2= 201/3.14
r^2= 64.01
square both sides
r= √64.01
r= 8.0 meters
Hence the radius is 8.0meters

Solve the equation on the interval [0,2pi)
The value of θ within the interval is 210 and 330 degrees
Given the equation;
[tex]2sin^2 \theta = 5sin \theta - 3[/tex]
Let P = sinθThe equation will become;
2P² = 5P - 3
2P² - 5P - 3 = 0
Factorize;
2P² - 6P + P- 3 = 0
2P(P-3) + 1(P -3) =0
2P + 1 = 0 and P - 3 = 0
p = -1/2 and 3
Since P = sinθ
sinθ = -1/2
θ = -30 degres
Since sine is negative in the second 3rd and 4th quadrant
θ = 180 + 30 = 210 degrees
θ2 = 360 - 30 = 330 degrees
Hence the value of θ within the interval is 210 and 330 degrees

Answer:
3.2mm ^3
Step-by-step explanation:
First find the scale factor to get the height of the smaller figure

Then use the Volume equation for triangular pyramid 1/3*(base area)*(height)
Your equation should look like this:
1/3 (4)(2.4)

Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = [tex]\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}[/tex]
From the given triangle,
Length of one side of the larger triangle = 8 units
Length of the corresponding side of the smaller triangle = 2 units
By substituting the values in the formula of scale factor,
Scale factor = [tex]\frac{8}{2}[/tex]
Scale factor = 4
At a party there are 90 people.
48 are women and 42 are men.
Some women leave.
Some men arrive.
The ratio of women to men is now
10:11
Are there now more than 90 people at the party?
Show working to support your answer.
Answer:
No
Step-by-step explanation:
Originally:
48:42
If some leave and some arrive = 10:11 given in question
So 48- 8 leave = 40 women
Therefore 42+2=44
Now the ratio is 40:44 (Actual amount of people)
When you simplify/ divide by 4 = 10:11
Total amount of people is 40+44= 84 which is less than 90

A right rectangular prism has base dimensions of 2 1 /10 ft wide and 4 1/ 5 ft long. If the height of the prism is 3 1 /2 ft, what is the volume of the prism?
Answer:
2 1/10 x 4 1/5 x 3 1/2 = 30 87/100 feet
(Remember multiply one by one first multiply 2 1/10 x 4 1/5 = 8 41/50
then multiply 8 41/50 with 3 1/2 to get = 30 87/100 is your answer)

Hey there!
2(12)3/2
= 2(12)(3/2)
= 24(3/2)
= 24/1 * 3/2
= 24(3) / 1(2)
= 24 + 24 + 24 / 1 + 1
= 48 + 24 / 2
= 72 / 2
= 72 ÷ 2 / 2 ÷ 2
= 36 / 1
= 36 ÷ 1
= 36
Therefore, your answer is: 36

Solve for the area of the figure below and show work.
Answer and Step-by-step explanation:
1. We can see that this kite-shape has 4 triangles in it.
The area of a triangle is as follows:
[tex]A = \frac{bh}{2}[/tex]
Where:
b = Base (length)
h = Height
Top Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Bottom Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Top Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Bottom Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Now, we add all the areas together to get the area of the kite figure.
A = [tex]\frac{27}{2}[/tex] +
A = 27 + 12
A = 39
The area of the kite figure is 39 [tex]m^{2}[/tex].
2. We have to find the area of the trapezoid.
(I'm not sure if the 9 is for the entire bottom side length)
If the bottom side length is 9, then we would use the formula:A = [tex]\frac{a + b}{2} h[/tex]
to find the area of the entire trapezoid.
A = [tex]\frac{2.4 + 9}{9}[/tex] × 8.2
A ≈ 46.74 [tex]mi^{2}[/tex]
