Answer:
8/35 de litro
Step-by-step explanation:
De la pregunta, sabemos que se necesitan 4/7 de un litro para pintar un metro cuadrado de pared.
Ahora necesitamos saber la cantidad de pintura necesaria para pintar 2/5 de un metro cuadrado.
Digamos que la cantidad necesaria es x
Ahora hagamos una relación matemática;
4/7 pinturas 1 metro cuadrado
x pintará 2/5 metros
cuadrados por lo tanto, x * 1 = 4/7 * 2/5 = 8/35
The Answer is B: 2,125 cm²
n = 7
a = 24.18 cm
r = 25.1051 cm
R = 27.8646 cm
A = 2124.65 cm²
P = 169.26 cm
x = 128.571 °
y = 51.4286 °
Agenda:
r = inradius (apothem)
R = circumradius
a = side length
n = number of sides
x = interior angle
y = exterior angle
A = area
P = perimeter
π = pi = 3.14159...

Formula: A = (1/4)na2 cot(π/n) = nr2 tan(π/n)
Total number of people = 125 + 100 = 225
Number of males = 100
Set as ratio
100:225
Simplify to 4:9 (can not simplify further without having decimals but you can’t have half a person)
We are given points

and

.
We first find the midpoint M, of AB, which divides the segment AB into 2 equal parts,
then we find the midpoint N of AM, and midpoint K of MB.
Thus each of the half parts is divided into 2 equal parts. The whole segment is divided into 4 equal parts.
The coordinates of M, N and K are found as follows:
the coordinates of M are:

the coordinates of N are:


similarly, the coordinates of k are:
