a. Two paths of width 2m each run across the middle of a rectangular
garden of length 60m and breadth 40m. What is the total area
covered by the both paths.
b. The area of a rectangular field is 60000 m². If the ratio of length
and breadth is 3:2, find its perimeter.
Answer:
196 m² ; 1000 m
Step-by-step explanation:
Given that:
Dimension of rectangular garden = 60m by 40m
Width of the 2 paths that run across each other = 2m
Hence,
Area of path 1 = (length * width) = (60 * 2) = 120m²
Area of path 2 = (breath * width) = (40 * 2) = 80m²
Area of Point where both paths cross each other (2 * 2) = 4m²
Total area covered by both path = (120m² + 80m² - 4m²) = 196m²
B.)
Area of rectangular field = 60000m²
Ratio of length and breadth = 3 : 2
Length * breadth = 60000
x ; breadth = (2/3)x
x * (2/3)x = 60000
2/3 x² = 60000
x² = 60000 ÷ 2/3
x² = 40,000
x = sqrt(40000)
x = 200
(3/2) * 200 = 300
Length = 300
Hence,
Perimeter = 2(length + breadth)
Perimeter = 2(300 + 200)
Perimeter = 2(500)
Perimeter = 1000m
write a coordinate proof. Given: Rectangle ABCD has vertices A(0,4), B(6,4), C(6,0), D(0,0). E is the midpoint of line DC. F is the midpoint of line DA. Prove: The area of rectangle DEGF is one fourth the area of rectangle ABCD.
Please help I've been trying for a while
Answer:
The answer is below
Step-by-step explanation:
Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The area of rectangle = length * breadth
The area of rectangle ABCD = |AB| * |BC|
[tex]|AB|=\sqrt{(6-0)^2+(4-4)^2}=6\\\\|BC|=\sqrt{(6-6)^2+(0-4)^2} =4[/tex]
The area of rectangle ABCD = |AB| * |BC| = 6 * 4 = 24
E(x, y) is midpoint of line DC. Its coordinate is:
x = (6 + 0) / 2 = 3; y = (0 + 0) / 2 =0
The coordinate of E = (3, 0)
F(a, b) is midpoint of line DA. Its coordinate is:
a = (0 + 0) / 2 = 0; b = (4 + 0) / 2 = 2
The coordinate of E = (0, 2)
The area of rectangle DEGF = |DE| * |DF|
[tex]|DE|=\sqrt{(3-0)^2+(0-0)^2}=3\\\\|DF|=\sqrt{(0-0)^2+(2-0)^2} =2[/tex]
The area of rectangle ABCD = |DE| * |DF| = 3 * 2 = 6
Therefore, area of rectangle DEGF is one fourth the area of rectangle ABCD

Use Phythogoras theorem:
[tex](AC)^2=(BC)^2+(AB)^2\\BC^2=AC^2-AB^2\\BC^2=6^2-4^2\\BC^2=36-16\\BC^2=20\\\\Apply\ square\ on\ both\ sides\\\\\sqrt{BC^2}=\sqrt{20} \\BC=\sqrt{20} \\BC=\sqrt{10(2)} \\BC=\sqrt{5(2)(2)} \\BC=2\sqrt{5}[/tex]
Q2)
Apply phythogoras theorem:
[tex]CD^2=CE^2+DE^2\\CD^2=7^2+9^2\\CD^2=49+81\\CD^2=130\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{CD^2} = \sqrt{130} \\\\CD=\sqrt{130} \\\\CD=11.4[/tex]
Q3)
Apply phythogoras theorem again:
[tex]BC^2=BD^2+CD^2\\BC^2=7^2+13^2\\BC^2=49+169\\BC^2=218\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{BC^2} =\sqrt{218} \\\\BC=\sqrt{218} \\\\BC=14.76[/tex]

Simple Interest
Compounded Quarterly
Compounded Monthly
Answer:
Compounded Quarterly
Step-by-step explanation:
This is because the compound interest equation is dependent on the number of times the amount is compounded per year. Monthly is 12 times per year and quarterly is only 4. Simple interest stays at a linear rate.

Catherine split rope that was 49.4 inches into
4 equal parts. What is the length of each part?
Answer:12.4 inch
Step-by-step explanation:
49.4 is the total length of the rope. And you have to equally divide it into 4 parts.
So 49.4/4
=12.4 inch(rounded off to 3 s.f from 12.35)

What is the equation of the line
that passes through the point
(-3,-5) and is parallel to the line
2x+3y=15
Answer:
y = (-2/3)*x -7
Step-by-step explanation:
2x+3y=15
3y = -2x + 15
y = (-2/3) *x + 5
slope for parallel line should be -2/3 too
pass (-3 , -5) y = mx + b b = y - mx = (-5) - ((-2/3) * (-3))
b = -5 - 2 = -7
parallel line: y = (-2/3)*x -7

A bucket holds b liters of water. But a jar holds 8 fewer liters than the bucket. How many times can the bucket hold than the jar? Thanks for your help!
Answer:
b / (b - 8)
Step-by-step explanation:
Given that :
Litres of water held by bucket = b
Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8
The number of times bucket can hold than jar is :
Litres held by bucket / litres held by jar
b / (b - 8)
Use the distributive property to remove the parentheses.
1. 3(8 + x)
2. 7(v - 2)
3. 3(v - 9)
Answer:
1. 24 + x
2. 7v - 14
3. 3v - 27
Step-by-step explanation:
Distributive property means that you go through something by either multiplying or dividing by whatever may be in the parentheses.
1. For one you would multiply the 3 through. 3 x 8 + 3x which can be simplified into 24 + 3x.
2. For two you would multiply the 7 through. 7v - 7 x 2, which can be simplified into 7v - 14.
3. For three you would multiply the 3 through. 3v - 3 x 9, which can be simplified into 3v - 27
Hope this helps!
Please tell me if I am incorrect I enjoy learning from my mistakes!
Good luck!

Find a premium on Property worth 20 500000 Rupees at 3% if (1) the property is fully insured (2) the property is insured for 80% of its value
Answer:
1)Premium = 615,000 Rupees
2)Premium = 492,000 Rupees
Step-by-step explanation:
Property worth = 20,500,000 Rupees
Premium rate = 3%
1) the property is fully insured means the property is insured to 100% of its value.
Thus, the insured value = 20,500,000 Rupees
Thus,
the premium = 20,500,000 × 3%
Premium = 615,000 Rupees
2) the property is insured to 80% of its value.
Thus, the insured value = 20,500,000 × 80% Rupees = 16,400,000 Rupees
Thus,
the premium = 16,400,000 × 3%
Premium = 492,000 Rupees
