Answer:

6.48

Step-by-step explanation:

The distance between her house and the school is 1800 meters.

We must use the relation:

distance = speed*time

Here we have:

We should rewrite the time into seconds, then we have:

15 minutes = 15*(60 seconds) = 900s

Then the distance is:

distance = (2m/s)*(900s) = 1800m

Hey ! there

Answer:

Step-by-step explanation:

In the question we're given that Salima takes 15 minutes from her house to reach her school on a bicycle and bicycle has speed of 2m/s .

And we are asked to calculate the distance between her house and the school .So for finding the distance we need to know the speed formula that is ,

[tex] \: \qquad \: \qquad \: \red{\underline{\red{\boxed{\frak{Speed = \frac{Distance}{Time}}}}}} [/tex]

So ,

[tex] \:\qquad \quad \underline{\boxed{ \frak{Distance = Speed \times Time} } }[/tex]✦

As it's given in the question that the speed of bicycle is 2 m/s and she takes 15 minutes to reach the school . So , for finding distance we must have to convert 15 minutes into seconds .

We know that ,

Therefore in 15 minutes we have ,

Now Solving : -

[tex] \longmapsto \: \qquad \: \sf{Distance =2 \times 900}[/tex]

By , multiplying 2 and 900 , We get :

[tex] \longmapsto \: \qquad \: \purple{\underline{\purple{\boxed{\frak{ {Distance = 1800 \: m}}}}}}[/tex]

Answer:

84 cm 2 :)

Step-by-step explanation:

Have a nice day!

Using factorization, the missing factor is (a + 6) of the given quadratic equation  a² + 8a + 12 = 0.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Given

The quadratic equation is a² + 8a + 12 = 0

The factor of the quadratic equation will be.

[tex]\begin{aligned}a^2 + 8a + 12 &=0 \\a^2 + 6a + 2a +12 &= 0\\(a+ 6)(a +2 ) &= 0\\\end{aligned}[/tex]

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Let, the number be = x

1) The value of __ divided by 32 is less that 1 that is :

x/32 < 1

x < 32

Any number less then 32 when divided by 32 will be less that 1.  

2)  The value of __ divided by 32 is equal to 1 that is :

x/32 = 1

x = 32

32 when divided by 32 will be equal to 1.

Therefore, the number will be :

1) Any number less then 32 when divided by 32 will be less that 1.  

2) 32 when divided by 32 will be equal to 1.

The area of a shape is the amount of space on the shape

The approximate area of the circle is 27.52 square units

The given parameters are:

Sectors = 16

Base = 1.17 units

Height = 2.94 units

The area of the triangle is:

[tex]A_1 = 0.5 * Base * Height[/tex]

So, we have:

[tex]A_1 = 0.5 * 1.17 * 2.94[/tex]

[tex]A_1 = 1.7199[/tex]

The approximate area of the circle is then calculated as:

[tex]A_2 = 16 * A_1[/tex]

This gives

[tex]A_2 = 16 * 1.7199[/tex]

[tex]A_2 = 27.52[/tex]

Hence, the approximate area of the circle is 27.52 square units

Answer:

27.52

Step-by-step explanation:

A = 1/2 bh

fill in the given information

A = 1/2 (1.17)(2.94)

multiply 1.17 and 2.94

A = 1/2 (3.4398)

Mutiply 3.4389 by 1/2 or divide 3.4398 by 2 (it is the same thing)

A = 1.7199

Now you have the area of one of the triangles, so you have to find the area of the whole circle or 16 triangles.

A = 1.7199 (16)

Mutpily

A = 27.5185

Step-by-step explanation:

The volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.

The volume of the sphere is defined as the amount of space occupied within the sphere. It is a space occupied by a three-dimensional object.

Given that the thickness of the ball is 2 cm and the outer radius r2 of the ball is 6 cm. The inner radius r1 of the ball is the difference between the outer surface and the thickness of the material.

r1 = 6-2

r1 = 4cm

The volume of the sphere ball is given as,

[tex]V = \dfrac {4}{3}\pi r^3[/tex]

For the inner radius, the volume is given as,

[tex]V_1 = \dfrac {4}{3}\times 3.14\times (4)^3[/tex]

[tex]V_1 = 267.94 \;\rm cm^3[/tex]

For the outer radius, the volume is given as,

[tex]V_2= \dfrac {4}{3}\times 3.14\times (6)^3[/tex]

[tex]V_2 = 904.32\;\rm cm^3[/tex]

The final volume of the ball is the difference between the volume of the inner and outer surface.

[tex]V = V_2 - V_1[/tex]

[tex]V = 904.32- 267.94[/tex]

[tex]V = 636.38 \;\rm cm^3[/tex]

Hence we can conclude that the volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.
