C ≈ 251.33

Step-by-step explanation:

The circumference of a circle is C = 2πr

Radius = r = 40 is given in the problem

C = 2* 3.14 * 40

C ≈ 251.33

Answer:

251.2

Step-by-step explanation:

Given,

Radius ( r ) = 40

To find : Circumference of a circle = ?

Formula : -

Circumference of a circle = 2πr

Note : -

The value of π is :

Solution : -

Circumference of a circle = 2πr

= 2 x 3.14 x 40

Width <= 5 and length <= 9

Step-by-step explanation:

Width: x

Length: x+4

2x + 2(x+4) <= 28 (less or equal)

2x + 2x + 8 <= 28

4x <= 28-8

x <= 20/4

x <= 5

If  length of a rectangle is 4 cm longer than the width the perimeter is no more than 28 cm. Then length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

The area of Rectangle is length times of width.

Let us consider width of rectangle be w= x cm

From given  length of a rectangle is 4 cm longer than the width

l=(x+4)cm

The perimeter of rectangle =2(Length+width)

=2(x+x+4)

=2(2x+4)

=4x+8

the perimeter is no more than 28 cm

4x+8≤28

Subtract 8 on both sides

4x≤20

Divide both sides by 4

x≤5

Hence  length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

The solution to given system of equations are x = -1, y = 1 and z = 5 which is determined by the substitution method.

The given system of equations below as

4x – 2y + 3z = 9  ....(i)

x - 2y = -3             ....(ii)

2x + 3y = 1            ....(iii)

By equation (ii) and solving for x to get

x - 2y = -3

x = 2y - 3    ....(iv)

Substitute the value of x = 2y - 3 in the equation (iii)

2(2y - 3) + 3y = 1

4y - 6 + 3y = 1

7y = 7

y = 1

Substitute the value of y = 1 in equation (iv) to get,

x = 2(1) - 3

x = -1

Substitute the values of x = -1 and y = 1 in equation (i), and solve for z

4(-1) – 2(1) + 3z = 9

-4 - 2 + 3z = 9

3z = 15

z = 5

Therefore, the solution to given system of equation are x = -1, y = 1 and z = 5.

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

The parent function is,

⇒ f (x) = x²

Now,

After the reflection across the x - axis, we get;

f (x) = - f (x)

Thus, The function is,

g (x) = - x²

And, Vertically stretched by a factor of 5, we get;

g (x) = - 5x²

And, Translated 3 units down, we get;

g (x) = - 5x² - 3

Thus, The vertex form of the function g will be;

Answer:

right it right

Answer:

The answer is 6.

Step-by-step explanation:

If there are 270 students going on the trip and there would be a teacher for every 45 students you would have to divide.

You would divide 270 ÷ 45 = 6.

The required number of teachers for the trip is 12.

Given that,
A school was taking a field trip. The principal wanted 2 teachers for every 45 students. If 270 students will be attending the trip how many teachers must chaperone is to be determined.

Proportionality is defined as between two or more groups of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.

Let the number of teachers is x and the number of students is y, which are directly proportional to each other
y ∝ x
y = km
where k is the constant proportionality.

at y = 45 x = 2
45 = K * 2
K = 45 / 2
Now,
y = 45/2 x
Now for y =270
270 = 45 / 2 x
x = 270 * 2 / 45
x = 12

Thus, the required number of teachers for the trip is 12.

The value of the given expression is 87.46.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be solved as below:-

E = 84-( -√12)

Two negative signs cancel out into a positive sign

E =84 + √12

84 plus the square root of 12. The square root of 12 is 3.5 or 3.46.

E = 84 + 3.46

E = 87.46
