The pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's area?
Answer:
The answer is- 40
Step-by-step explanation:
( :
The area of the pentagon represented here is 40 units².
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that the coordinates of the vertices of the pentagon given are A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0).
We have to find the area.
This pentagon can be divided in to triangle CBD and trapezium ABDE.
Find the area of each to find the total area of the pentagon.
Area of ΔCBD = [tex]\frac{1}{2}[/tex] × BD × CB
Using the distance formula,
BD = [tex]\sqrt{(8-3)^2+(5-5)^2}[/tex] = 5
CB = [tex]\sqrt{(3-3)^2+(5-8)^2}[/tex] = 3
Area of ΔCBD = [tex]\frac{1}{2}[/tex] × 5 × 3 = 7.5
Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (AE + BD) × DE
Using the distance formula,
AE = 8, BD = 5 and DE = 5
Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (8 + 5)5 = 32.5
Total area of the pentagon = 7.5 + 32.5 = 40 units²
Hence the total area is 40 units².

A rectangular city lot has an area of 1,000 square meters. If the length of the lot is 10 meters more than twice its width, find the length and width. Write the quadratic equation.
Answer:
Length of the Area = 50mtrs
Width of the Area = 20mtrs
Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans
Brain test! Answer the question below.
lol ok so im stuck on this pls help
Answer:
The slope is -5
y intercept is -2
Step-by-step explanation:
Solve the equation for y
5x+y =-2
Subtract 5x from each side
5x+y -5x = -5x-2
y = -5x-2
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -5 and the y intercept is -2
Answer:
Slope -5
y intercept 2
Step-by-step explanation:
5x+y=-2 in the form y =Mx+ c is,.
y=-5x+-2
y=-5x-2
Where m is the slope which is -5
And c is the y intercept i.e 2

Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is half of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058

what is the volume of the figure below
Answer:
665 ft^3
Step-by-step explanation:
The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.
14 x 9.5 x 15 = 1995
1995 / 3 = 665
So the volume is 665 cubic feet

The ratio of the number of Aaliyah’s pens to the number of Mariah’s pens was 2:3 at first. After Dad gave Aaliyah another 16 pens, the ratio became 2:1.
a) How many pens did Mariah have?
b) If Mariah gave away 6 pens, what would be the new ratio of the number Aaliyah’s pens (after Dad gave her 16 pens) to the number of Mariah’s pens?
y'all better help me with this one
Answer:
(2x + 16)/3x = 2/1
2x + 16 = 6x
4x = 16
x = 4
Aaliyah's pens = 2x = 2 × 4 = 8
the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A
New ratio = (8 + 16)/6
24/6 = 4/1 = 4 : 1 --------- Part B Step-by-step explanation:
