increase 140 in the ratio 7:5.​

Answer:

Solution:- In the given figure

Side of square= 10 cm

area of square =  side x side m= 10 x 10 = 100 sq cm

Now , diameter of semi circle AOD = 2r = 10cm

⇒ radius of  semi circle AOD = 5 cm

∴ area of AOD =  

similarly Area of semicircle BOC =  

Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]

=

Total area of white portion in the given figure=

∴Area of Shaded portion = area of square - area of total white portion

=  

So the area of shaded portion is  

Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)

So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

Answer:

The answer is 2

Step-by-step explanation:

First you need to calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. All of the points add up to 10. Then you divide that number by how many points there are which is 5 and you get 2.

Answer:

Step-by-step explanation:

Let shall be considering the Cosine rule in this situation.

a^2 = b^2+c^2- 2bc.cosA

Where a = ?

b = 21km

c 45km

A = 131

a^2 = 21^2+45^2-2(21*45).cos131

a^2 = 441+2025-1890(-0.6560)

a^2 = 2466+1239.951

a^2 = 3705.951

a= 60.876km

Finding the bearing of the port from the ship.

We shall be considering the Sine rule

Sin A/a = Sin B/b

Where A = ?

a = 45km

B = 131°

b = 60.876km

Sin A/45 = sin131/60.876

SinA×60.876 = 45×sin131

SinA×60.876= 45×0.7547

SinA×60.876 = 33.961

SinA= 33.961/60.876

SinA = 0.5578

A = sin^-1 0.5578

A = 33.9°

Answer:

x = 19.8

Step-by-step explanation:

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

thus, we have it that;

16/28.8 = 11/x

16 * x = 11 * 28.8

x = (11 * 28.8)/16

x = 19.8

The correct option is (b) i.e. In the given synthetic division, the remainder will be 7.

What is Remainder ?

The remainder is what "remains" after an activity is finished, as its name implies. In mathematics, it is impossible to divide 17 by 3 precisely. The leftover after division is the number 2, which is set aside.

Given : 1   |    4 6 -3

If we solve it further, we get

                               1   |    4 6 -3

                                   |        4  10

                                   |    4 10  7

Steps :

firstly we will write 4 as it is .

we will multiply 1 by 4 and write it in the second place, then we will add 6 and 4.

Similarly, we will multiply 1 by 10 and write it in the third place, then we will add -3 and 10 and finally get 7 as residual.

here, after solving, we get 7 in the end which is set aside.

So, the remainder will be 7.

Hence, the correct option is (b).

Answer:

8 cm

Step-by-step explanation:

If the 16 cm is the diameter then the radius is 8 cm. To find the radius of a circle you simply divide two by the diameter. 16 ÷ 2 = 8

Answer: m = 1/2 or 0.5

Step-by-step explanation:

The order of operation within this problem is multiplication meaning we must divide instead.

2m = 1

2m/2 = 1/2

m = 1/2 or 0.5

Veremos que en la imagen 10 hay 37 circulos, y la diferencia entre las imagenes 12 y 7 es de 20 circulos.

Primero, debemos contar la cantidad de circulos que tenemos en las imagenes mostradas.

Entonces podemos ver que en cada imagen se agregan 4 circulos, es decir tenemos una secuencia aritmetica, de tal forma que la imagen número N tendremos:

[tex]C_N = 1 + (N - 1)*4[/tex]

Entonces, cuantos circulos hay en la imagen 10? para ver eso reemplazamos N por 10.

[tex]C_{10} = 1 + (10 - 1)*4 = 37[/tex]

¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7?

Para ver esto calculamos:

[tex]C_12 - C_7 = (1 + (12 - 1)*4) - (1 + (7 - 1)*4) = 11*4 - 6*4 = 20[/tex]

Es decir, la image 12 tiene 20 circulos más que la imagen 7.

Answer: B. One fourth times the product of 8 and 3, then divide by 5.

Answer:

y = (1/4)*x + 3

Step-by-step explanation:

A linear equation can be written as:

y = a*x + b

Where a is the slope, and b is the y-intercept.

If the line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that the line passes through the points (0, 3) and (8, 5)

Then the slope will be:

a = (5 - 3)/(8 - 0) = 2/8 = 1/4

Then this line is something like:

y = (1/4)*x + b

Now we want to find the value of b.

Here we can use one of the two points that we know, for example, I will use the point (0, 3), this means that when x = 0, we must have y = 3.

If we replace those two values in the line equation, we get:

3 = (1/4)*0 + b

3 = b

Then the equation for the line L is:

y = (1/4)*x + 3
