3. The trapezoid below contains a square and two right triangles. Find the perimeter of the trapezoid.
Answer:
Perimeter of trapezoid = 25.66 cm
Step-by-step explanation:
Trapezoid ABCD contains two triangles ΔABF, ΔCDE and a square with side length 4 cm.
By applying Pythagoras theorem in ΔABF,
AB² = BF² + AF²
AB² = 4² + 3²
AB = [tex]\sqrt{16+9}[/tex]
AB = 5 cm
Similarly, By applying Pythagoras theorem in ΔCDE,
CD² = DE² + CE²
CD² = 4² + 4²
CD = [tex]\sqrt{32}[/tex]
CD =5.66 cm
Perimeter of the given trapezoid = AB + BC + CD + AD
= 5 + 4 + 5.66 + (3 + 4 + 4)
= 25.66 cm

The Perimeter of the Kite whose dimensions 8 in., 10 in. and 8 in. is 26 inches.
What is the Perimeter of Kite?
A kite has two pairs of equal size. Total distance around the outside is called the perimeter of a kite. This distance can be found by calculating the sum of the lengths of each pair.
Here, the perimeter of kite = a + b + c
= 8 + 10 + 8
= 26 inches.
Thus, the Perimeter of the Kite whose dimensions 8 in., 10 in. and 8 in. is 26 inches.

paul got 72 marks in a maths test. 72 marks is 60% of the total number of marks. work out the total number of marks in the test
Answer:
115.2 total marks.
Step-by-step explanation:
If 72 is only 60% of the total marks, then to find the total number of marks we will need to multiply 72 by 60% to find the remaining marks, then add that back to 72.
72 × 0.6 = 43.2 remaining marks.
72 + 43.2 = 115.2 total marks.
The total number of marks in the test is 115.2 total marks.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that paul got 72 marks in a maths test. 72 marks is 60% of the total number of marks.
When 72 is only 60% of the total marks, then to find the total number of marks.
We will need to multiply 72 by 60% to find the remaining marks, then add that back to 72.
Then, 72 × 0.6 = 43.2 remaining marks.
72 + 43.2 = 115.2 total marks.

A population of rabbits doubles every 4 months. If the population starts out with 8 rabbits how many will there be in 1 year
Given:
The initial population of rabbit = 8
Population of rabbits doubles every 4 months.
To find:
The number of population in 1 year.
Solution:
The exponential growth model is
[tex]y=a(b)^x[/tex] ...(i)
Where, a is the initial population, b is growth factor, x is time period.
We know that,
12 month = 1 year
So, there are 3 time period of 4 months in an year.
Initial population of rabbit (a) = 8
Population of rabbits doubles every 4 months. So, growth factor is 2, i.e., b=2 and the time period is 3, i.e., x=3.
Putting a=8, b=2, x=3 in (i), we get
[tex]y=8(2)^3[/tex]
[tex]y=8(8)[/tex]
[tex]y=64[/tex]
Therefore, the population of rabbit in 1 year will be 64.

Step-by-step explanation:
The slope of the line y = (x/4) - 23/4 is 1/4.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
The points,
x → y
-4 → -3
1 → -2
6 → -1
11 → 0
From the table, we interpreted 2 points (-4, -3) and (11, 0)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂),
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (0+3) / (11+4)
m = 1/5
So, the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) (x - x₁)
y - y₁ =m (x - x₁)
y +3 = (1/4) (x -11)
y = (x / 4) - 11/4 -3
y = (x/4) - 23/4
Therefore, the slope of the line is m = 1/5.
