Answers
Answer:
Equal, equal, not equal, not equal
Step-by-step explanation:
A) Equal, because they have the same height and base. To find the area of a triangle, you use "(b+h)/2". In this situation, the "b" and the "h" are equal.
B) Equal, as they also have the same height and base. To find the area, you use b*h, and they are equivalent.
C) Not equal. The two lengths given are not equal.
D) Not equal. The two triangle's heights are equal, but their bases are not. If you look at the second triangle, you can see that if is further from the triangles' intersections. This means that the base is larger than the one on the left.

Vaughn is ordering light bulbs for his business. He always orders three extra bulbs. The following shows how the number of light bulbs he orders, y, changes as the number of light bulbs burnt out, x, changes.
Which equation shows this relationship?
A.
y = 3x
B.
y = x + 3
C.
3y = x
D.
y + 3 = x
Answers
Answer: D
Step-by-step explanation:
Because if y is the number of light bulbs he orders and he always orders three extra or three more that means that for any number of orders that he makes there will be three more. That three will never change since he always others three more than he ordered.

A sector with an area of 140 pie cm^2 has a radius of 20 cm.
r = 20 cm
A = 140 pie cm^2
What is the central angle measure of the sector in degrees?
Answers
Answer:
Central angle = 126°
Step-by-step explanation:
Area of the sector = 140π cm²
Radius of the given circle = 20 cm
Since area of the sector = [tex]\frac{\theta}{360}\times (\pi r^{2})[/tex]
[where θ is the central angle formed by the sector at the center]
140π = [tex]\frac{\theta}{360}(\pi)(20)^{2}[/tex]
θ = [tex]\frac{(140\pi)\times 360}{400\pi }[/tex]
θ = 126°
Therefore, central angle of the sector will be 126°.

Answers
Answer:
2080
Step-by-step explanation:
The surface area of the cylinder is 2080π square feet. Answer: 2,080 pi feet squared.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
The formula for the surface area of a cylinder is:
SA = 2πr² + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).
Since the diameter is given as 40 feet, the radius is half of that, or 20 feet.
So, substituting the values into the formula, we get:
SA = 2π(20)² + 2π(20)(32)
SA = 2π(400) + 2π(640)
SA = 800π + 1280π
SA = 2080π
Therefore, SA = 2080π.

Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius ), thus
V = [tex]\frac{4}{3}[/tex]π × 5³
= [tex]\frac{4}{3}[/tex]π × 125 = [tex]\frac{4(125)}{3}[/tex]π = [tex]\frac{500}{3}[/tex]π units³ → D
The volume of the sphere of the given figure is [tex]\frac{500}{3} \pi units^{3}[/tex] .Option D is correct.
It is given that the radius(r) of the sphere is 5 unit.
It is required to find the volume of the sphere of the given figure.
What is the volume of the sphere below?As we know the volume of the sphere is:
V = [tex]\frac{4}{3} \pi r^{3}[/tex]
Where, r represents the radius of the sphere.
Now putting the value of 'r' in the formula,
V = [tex]\frac{4}{3}\pi (5)^{3}[/tex]
V = [tex]\frac{4}{3} \pi[/tex]×(125)
V = [tex]\frac{4 (125)}{3}\pi[/tex]
V = [tex]\frac{500}{3} \pi[/tex] [tex]unit^{3}[/tex]
Thus, the volume of the sphere of the given figure is [tex]\frac{500}{3} \pi units^{3}[/tex] .

Answers
Answer:
Volume = ⅔πr³
Step-by-step explanation:
Given
Shape: Cone
Height = 2 * Radius
Required
An expression for the volume of the cone.
Let h and r represent the height and the radius of the cone, respectively.
So, h = 2r.
So solve this question, we simply write out the formula to calculate the volume of a cone.
Volume = ⅓πr²h
Substitute 2r for h.
Volume = ⅓πr²(2r)
Volume = ⅓πr² * 2r
Volume = ⅔πr³
Hence, the above expression represent the volume of a cone when h = 2r
The expression that represents the volume of the cone in cubic units is: ⅔πr³.
What is the Volume of a Cone?Volume of cone = ⅓πr²h
r is the radius; h is the height of the cone.
Given:
Radius of the cone = rHeight = 2(r) = 2rTherefore, substitute the values into the formula for the volume of a cone:
Volume of cone = ⅓π(r²)(2r)
Volume of cone = ⅔πr³
Therefore, the expression that represents the volume of the cone in cubic units is: ⅔πr³.

Find the exact value of sec30°.
Answers
Decimal Form:
1.15470053
…
Step-by-step explanation:
The exact value of sec(30°) is 2√3 / 3.
We have,
To find the exact value of sec(30°), use the trigonometric identity:
sec(θ) = 1 / cos(θ)
Now,
cos(30°) = √3 / 2
Now, substitute this value into the formula for sec(θ):
sec(30°) = 1 / cos(30°) = 1 / (√3 / 2)
sec(30°) = 2 / √3
To rationalize the denominator, multiply the numerator and denominator by √3:
sec(30°) = 2 / √3 * √3 / √3
= 2√3 / 3
Therefore,
The exact value of sec(30°) is 2√3 / 3.
