AABC shows the floor space that a corner cabinet takes up. What is the
area?
Answers
The area of the triangle is 2√5 square units
Arwa of a triangleThe formula for finding the area of a triangle is expressed as:
A = 0.5bh
b is the base
h is the height of the triangle
Using the distance formula
b = AC = √(5-1)²+(0-2)²
base =√20
base = 2√5
For the height
h = √(1-3)²+(4-4)²
base =√2²
base = 2
Area = 0.5(2)(2√5)
Area = 2√5 square units
Hence the area of the triangle is 2√5 square units

Answers
Answer: 76.8km/hr
Explanation:
PT1
sp1 - 30km/hr
d1 - 60km
60 divided by 30 = 2hrs
PT2
sp2 - 160km/hr
d2 - 180km
180 divided by 30 = 1hr, 7min, 30sec (1.125)
PT3
Total Time Taken - 2hrs + (1:07:30) 1.125 = 3.125hrs
Avg. Speed - (60km + 180km) divided by 3.125hrs
60km + 180km = 240

The perimeter of a shape is the sum of its side lengths
The perimeter of the quadrilateral is approximately 25 units
How to determine the perimeterThe vertices of the quadrilateral MNOP are given as:
M = (-3,4)
N = (-1,4)
O = (4,-5)
P = (2,-5)
Start by calculating the lengths of the side lengths using the following distance formula
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]MN = \sqrt{(-1 +3)^2 + (4 -4)^2} = 2[/tex]
[tex]NO = \sqrt{(4+1)^2 + (-5 -4)^2} \approx 10.3[/tex]
[tex]OP = \sqrt{(2-4)^2 + (-5 +5)^2} =2[/tex]
[tex]PM = \sqrt{(-3-2)^2 + (4+5)^2} \approx 10.3[/tex]
The perimeter is then calculated as:
[tex]P = 2 + 10.3 + 2 +10.3[/tex]
Add
[tex]P = 24.6[/tex]
Approximate
[tex]P = 25[/tex]
Hence, the perimeter of the quadrilateral is approximately 25 units

Two trains, train A and train B,weigh a total of 240 tons. Train A is heavier than train B. The difference of their weights is 70 tons. What is the weight of each train?
Answers
Answer:
Train A : 155 tons ; Train B : 85 tons
Step-by-step explanation:
Call train A as A, train B as B
A + B = 240t
A - B = 70t
Add these 2 together, we get :
A + B + A - B = 310t
2A = 310t (B-B = 0)

Find Two consecutive positive integers such that the square of the larger integer is nineteen more than nine times the smaller integer
Answers
Answer:
9 and 10
Step-by-step explanation:
To start, let's have what we know:
a and b are two consecutive positive integers
a = first integer
b = second integer, 1 greater than variable a
b = a + 1
b^2 = 19 + 9a
To solve this, we would only have to substitute values in
b^2 = 19 + 9a
(a+1)^2 = 19 + 9a
a^2 + 2a +1 = 19 + 9a
-9a -19 -19 - 9a
a^2 -7a - 18 = 0
a^2 + 2a - 9a - 18
a(a + 2) - 9(a+2) = 0
(a - 9)(a + 2) = 0
So solving this, we would get a = 9 or a = -2. Since this is supposed to be a positive integer, a will be 9.
Solving for b,
b = a + 1
= 9 + 1
= 10

Angel has a rectangular garden that is 15 feet longer than it is wide. A cement path that is 4 feet wide surrounds the garden. The total area of the path is 632 sq. ft. what are the dimensions of the garden?
Answers
Answer:
43 ft. long, 28 ft. wide, area is 1204 sq. ft.
Explanation:
I had to draw a diagram for this, and I scribbled all over it, so bear with me as I try to describe this:
The garden is x+15 ft long, and x ft wide. The path is x+23 ft long, and x+8 ft wide, because the path adds 4 ft all around. If you cut the path into smaller rectangles, and find the area of the rectangles, the path is concluded have an area of 16x+184 sq. ft. We already know the area of the path is 632 sq. ft, which in equation form is 16x+184=632. If you solve for x, you get 28 ft. That means the width of the garden is 28 ft. If the length is 15 ft. longer than the width, the length is 43 ft. I also calculated the area for just in case you need it. Let me know if this was helpful in the comments.
