The number of students who come to school through other modes o transportation is 1,165.

The number of students who come to school through other modes o transportation can be calculated as follows:

A = Number of girls that uses other modes o transportation = (100% - 40%) * 950 = 570

B = Number of boys that uses other modes o transportation = (100% - 30%) * (1800 - 950) = 595

C = Total number of studens that uses other modes o transportation = A + B = 570 + 595 = 1,165

Answer: 346.19cm²

Step-by-step explanation:

π= 3.14

Divide 21 (the diameter) by 2 to get the radius( it 's half of the diameter). so the radius is 10.5

Area= πr²

       = 3.14x10.5x10.5

       = 346.185

So next round up the value you got to the nearest tenth, so when u round up to the nearest tenth you get 346.19

Answer:

The triangles are not similar.

Step-by-step explanation:

First, what's all the information we know?
We know we're trying to prove that triangle BAC is similar to triangle DEC.
We know AC=12 and EC =12 (proving 1 side equal).
We know angle BCA and angle DCE or equal.
However, we do not know any information further than this, and there is no postulate/theorem for AS. Therefore, the triangles are not similar.

If f(x) and f¹(x) are inverse functions of each other then value of ƒ˜¹ (8) = 3/2.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

We have,

f(x) = 2x + 5

Let us consider f(x) as y

So, y= 2x + 5

Now replace x to y and y to x

x= 2y+ 5

Solving for y we get

2y = x - 5

y = (x - 5)/2

[tex]f^{-1[/tex](x) = (x - 5)/2

Now, [tex]f^{-1[/tex](8) = (8 - 5)/2

[tex]f^{-1[/tex](x) = 3/2

The computation of (TR)546 - (TR)540 will give a value of 3261.

TR(546)  =  546(546 + 1)/2  =  273 * 547

TR (540)  =  540(540 + 1)/2  =  270 * 541

273 * 547  = (270 + 3)(541 + 6)

= 270*541  + 270*6  + 541 *3  +  18

= 270*541  + 1620  + 1623  +  18

= 270*541  + 3261

TR(546) -TR (540)   = 270*541  + 3261  - 270 * 541

= 3261  

TR(546) -TR (540)   = 3261

Answer:

Area of Circle  = 346.5 cm².

Area of square = 272.25 cm ² .

Step-by-step explanation:

So , 2πR = 66

2 × 22 / 7 × R = 66

R comes out is 21/2 cm .

Area of Circle = 22/7 × 21/2 × 21/2 = 33×21/2

= 693 / 2 = 346.5 cm².

If bent into the shape of a square ;

4 a = 66

Area of square = a ² = 33×33/4 = 1089/4

= 272.25 cm ² .

Answer:

14 inch ^2

Step-by-step explanation:

Area of a trapezium= (a+b) 2 times h

so side a= 5 inches

    side b= 9 inches

then times by 2 times the height (2)

you can rearrange the formula to this- a + b/ 2 times height.

Considering the definition of axis of symmetry, the axis of symmetry of the graph of the function f(x) = 3x²+ 12x+ 9 is x=-2.

An axis of symmetry is an imaginary reference line that, when dividing any shape into two parts, its opposite points are equidistant from each other, that is, they are symmetrical.

In other words, the axis of symmetry is a vertical line that divides the parabola into two congruent halves.

The axis of symmetry is the line perpendicular to the "x" axis that contains the vertex of the function, that is, it always passes through the vertex of the parabola. So the x-coordinate of the vertex is the equation of the axis of symmetry.

That is, in a quadratic function that has the form:

f(x)= ax² + bx + c

the axis of symmetry is a vertical line and it is defined as [tex]x=\frac{-b}{2a}[/tex].

In this case, you know:

Replacing in the definition of axis of symmetry:

[tex]x=\frac{-12}{2x3}[/tex]

Solving:

[tex]x=\frac{-12}{6}[/tex]

x= -2

Finally, the axis of symmetry of the graph of the function f(x) = 3x²+ 12x+ 9 is x=-2.

nth term = n(n + 2)

Step-by-step explanation:

Note that the first number in each parentheses is the sequence number n of the term. This  value of n is then multiplied by (n + 2) - for example 3 x 5

( 3 x (3+2)).

So the nth term = n(n + 2).
