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.

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.

Hence, The total number of marks in the test ​ is 115.2 total marks.

Answer:

26

Step-by-step explanation:

8+10+8=26

The Perimeter of the Kite whose dimensions 8 in., 10 in. and 8 in. is 26 inches.

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.

Answer:

Step-by-step explanation:

The slope of the line y = (x/4) - 23/4 is 1/4.

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.

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

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.
