Point Lis a centroid of the triangle FWD, If RL = 54 cm, what is RD?
O 81 cm
O 162 cm
O 100 cm
O 58 cm
Answers
Answer:
RD = 162 cm
Step-by-step explanation:
LD = 2 RL = 2* 54 = 108
RD = RL + LD
RD = 54 + 108
RD = 162 cm
The length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have:
Point L is a centroid of the triangle FWD, If RL = 54 cm
From the centroid definition:
LD = 2RL
LD = 2×54 = 108 cm
RD = RL + LD
RD = 54 + 108
RD = 162 cm
Thus, the length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.

Answers
Answer:
$60.00
Step-by-step explanation:
first take 50 and find 10% of that. we can do this by turning 10 into 0.1 and multiplying that by 50. this leaves you with 5. take 5 and multiply by 2 representing the 2 years, and get 10. then add the $10 to the $50 to get $60. hope this helped! pls give brainliest <3 :)
determine the slope of the line that contains (-4,2) and (6,8)
Answers
please help me with this i dont know wht im doing
Answers
Answer:
D: The slope is 3
Step-by-step explanation:
To figure out the slope, which is always a constant, you simply figure out the average displacement using the points we already know. This is described by the equation y2-y1/x2-x1. Let's use the ordered pairs (-3, 2) and (-1, 8) to figure this out.
8-2/-1-(-3) = 6/2 = 3
Another method you could use is to graph the points and figure out how many units y has to go up for every x over, or the "rise over run"
Either way, your slope is 3.
Answer:
its 3

A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.

Step-by-step explanation:
y - 2 = 1/2(x - 10)
y - 2 = 1/2x - 5
y = 1/2x - 3
Answer:
Step-by-step explanation:
You can read the slope right away.
y = 0.5x + b 1/2 = 0.5
The point will determine the y intercept
2 = 0.5*10 + b
2 = 5 + b
2-5 = b
b = - 3
The line is y = 0.5x - 3

What is the equation of the line that passes through the point (−3,4) and has a slope of 1 ?
Answers
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1, thus
y = x + c ← is the partial equation
To find c substitute (- 3, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = x + 7 ← equation of line

We have following equation to find the point-slope form of the linear functions.
[tex]y - y(0) = m \times ( \: x - x(0) \:) [/tex]
In which :
[tex]y(0) = y \: \: given \: \: point = 4[/tex]
[tex]x(0) = x \: \: given \: \: point = - 3[/tex]
[tex]m = slope = 1[/tex]
Now just need to put the coordinates and the slope in the above equation.
[tex]y - 4 = 1 \times ( \: x - ( - 3) \: )[/tex]
[tex]y - 4 = x + 3[/tex]
Add sides 4
[tex]y - 4 + 4 = x + 3 + 4[/tex]
[tex]y = x + 7[/tex]

Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.
Answers
Answer:
its 1/3 of the volume of a cyinder with the same base
Step-by-step explanation:
a pyramid has the same policy with prisms of the same base
Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
What is volume?
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.
The volume of the cone with radius r units and height h units now can be written as,
Volume of the cone = (1/3) × π × r² × h units³
The volume of the cylinder with a radius of r units and the height of h units now can be written as,
Volume of the Cylinder = π × r² × h units³
Taking the ratio of the volume of the cone and the volume of the cylinder,
Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³
Volume of the cone/Volume of the cylinder = 1/3
Volume of the cylinder = 3 × Volume of the cone
Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
