A plot of land is 25 feet in length and 20 feet wide, and it is in the shape of a parallelogram. The perpendicular distance from the long side to the opposite long side is 18 feet. What is the area of the piece of land?
Given:
Length of the parallelogram = 25 feet
Width of the parallelogram = 20 feet
Perpendicular distance from the long side to the opposite long side = 18 feet.
To find:
The area of the piece of land which is a parallelogram.
Solution:
Area of a parallelogram:
[tex]Area=Base\times height[/tex]
Let the longer side, 25 feet is the base, then the height of the parallelogram is 18 feet. So, the area of the parallelogram is
[tex]Area=25\times 18[/tex]
[tex]Area=450[/tex]
Therefore, the area of the piece of land is 450 square feet.

Step-by-step explanation:
A system of linear equations has no solution when the equations describe parallel lines. Parallel lines have the same slope. In your equation, the slope is the x-coefficient, 8. A parallel line will have a slope of 8.
The second equation will have a slope of 8 if the system has no solution.

1) The region enclosed by the x-axis, the line x=3 and the curve y = sq. Rt x is rotated about the x-axis. What is the volume of the solid generated? *
Using the disk method, the volume would be
[tex]\displaystyle \pi \int_0^3 (\sqrt x)^2 \,\mathrm dx=\pi \int_0^3 x\,\mathrm dx=\frac\pi2 x^2\bigg|_0^3=\boxed{\frac{9\pi}2}[/tex]
That is, you split up the solid into disks of some small height ∆x, and each disk has radius at point x equal to the distance (√(x)) from the axis of revolution (the x-axis, y = 0) to the curve y = √(x). The volume of such a disk is then π (√(x))² ∆x. Take the sum of these volumes to get the total volume, then as the heights get smaller and smaller, replace ∆x with dx and the sum with the integral.
In this exercise we have to use the knowledge of the integral to calculate the volume of the disk that will correspond to:
[tex]V= \frac{9\pi }{2}[/tex]
That is, you split up the solid into disks of some small height ∆x, and each disk has radius at point x equal to the distance (√(x)) from the axis of revolution (the x-axis, y = 0) to the curve y = √(x). The volume of such a disk is then π (√(x))² ∆x. Take the sum of these volumes to get the total volume, then as the heights get smaller and smaller, replace ∆x with dx and the sum with the integral. Using the disk method, the volume would be:
[tex]\pi \int\limits^3_0 {(\sqrt{x})^2} \, dx = \pi \int\limits^3_0 {x} \, dx = \frac{\pi x^2}{2} = \frac{9 \pi }{2}[/tex]

Solve in simultaneous
A=

Answer:
A= 3,B = 2
Hope it helps you
if yes mark me brainliest
Answer:
hence, a = 3
b = 2
Step-by-step explanation:
from the given pair of linear equation we get,
7a + 3b = 27 - ( 1 )
6a + 3b = 24 - ( 2 )
now, subtract equation 2 from equation 1
=》7a + 3b - 6a - 3b = 27 - 24
=》a = 3
now put the value of a in equation 1
=》7a + 3b = 27
=》( 7 × 3 ) + 3b = 27
=》21 + 3b = 27
=》3b = 27 - 21
=》b = 6 ÷ 3
=》b = 2

Step-by-step explanation:
Decide which of the two points lies on the graph of the line.
1. X + Y = 8
A. (2,4) B. (2,6)
2. X = 4
A.(4,2) B. (2,4)
3. Y = X - 2
A. (4,6) B. (6,4)
Answers:
B) (2,6)A) (4,2)B) (6,4)===========================================
Explanations:
For this problem, the x and y coordinates must add to 8. In choice A, we have x+y = 2+4 = 6, which doesn't work. But choice B does work since x+y = 2+6 = 8. Therefore, the point (2,6) is located on the line x+y = 8. The equation x+y = 8 is equivalent to y = -x+8.The x coordinate must be equal to 4. The y coordinate can be anything you want. The point (4,2) is on this line, while (2,4) is not. Another point on this line is (4,1). The line is completely vertical.If we plugged the x & y coordinates of choice A into the equation, we get 6 = 4-2 which then becomes 6 = 2 and that's a false statement. That rules out choice A. If we try choice B, then we get 4 = 6-2 which becomes 4 = 4. We get a true statement so choice B is the answer.Plzzzzzzz helppp i will give brainliest if right

Answer:
128 square feet
Step-by-step explanation:
Horizontal Gray parts:
12 - 8 = 4 ÷ 2 = 2
2 * 24 = 48 * 2 = 96
Vertical gray parts:
24 - 20 = 4 ÷ 2 = 2
2 * 8 = 16 * 2 = 32

A ladder leaning against a wall makes a 60° angle with the ground. The base of the ladder is 3 m from the building. How high above the ground is the top of the ladder?
Answer:
The distance is 5.20m
Step-by-step explanation:
Here, we want to get the height of the ladder
To get this, we need to understand that we have a right triangle, with the base of the triangle as 3 m, the angle at the downward part is 60, and we want to get the height of the triangle
The angle here faces the height we want to calculate
This height is known as the opposite
What we have is the adjacent
Now, the trigonometric identity that relates the opposite and the adjacent is the tan
The tangent of an angle is the ratio of the opposite to the adjacent
Mathematically;
tan 60 = h/3
h = 3 tan 60
h = 5.20 m
The ladder is at a height of 5.20 m above the ground

Then you want to get p by itself.
Multiply the 9 out:6p = 9p+81Subtract 9p from both sides:-3p = 81Divide -3 both sides to get p by itself:p = -27Maya runs 8 miles in 84 minutes. At the same rate, how many minutes would she take to run 6 miles?

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 3 , 106 )
Let the second point be Q ( 6 , 187 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 187 - 106 ) / 3
Slope m = 27
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 106 = 27 ( x - 3 )
y - 106 = 27x - 81
Adding 106 on both sides , we get
y = 27x + 25 be equation (1)
Now , let the equation of line be represented as B
And , the value of B is
Let the first point be R ( 3 , 105 )
Let the second point be S ( 6 , 165 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 165 - 105 ) / 3
Slope m = 20
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 105 = 20 ( x - 3 )
y - 105 = 20x - 60
Adding 105 on both sides , we get
y = 20x + 45 be equation (2)
Now , when x = 1
Substitute the value of x = 1 in equation (1) and equation (2) , we get
y₁ = 27 + 25 = $ 52
y₂ = 20 + 45 = $ 65
So , health club B costs $ 7 less than health club A every month
Hence , the equation of lines is solved
