Answer:
La razón geométrica de mujeres a varones es de 3 mujeres por cada 4 hombres. 
Step-by-step explanation:
El enunciado es incorrecto, su forma correcta es: <em>En una escuela hay 196 estudiantes, de los cuales 84 son mujeres. La razón geométrica de mujeres a varones que estudian en dicha escuela es:</em>
Es sabido que la especie humana solo tiene dos formas en un sentido biológico: hombre y mujer. Si 84 de los 196 estudiantes son mujeres, entonces 112 son hombres. En consecuencia, la razón geométrica de mujeres a varones es de 3 mujeres por cada 4 hombres. 
 
        
             
        
        
        
Okay. The formula for simple interest is prt. You multiply the principal (initial amount) by the rate (percentage) by the time (months or years). $1,800 is the principal and 6.5% is the percentage rate. 1,800 * 6.5% (0.065) is 117. You earn $117 in interest annually. The time period is 30 months. There are 12 months in 1 year. Divide the amount of months by 12 to put it in a decimal. 30/12 is 2.5. Now, multiply 117 by 2.5 to find the total amount of interest earned. 117 * 2.5 is 292.5. There. The total amount of interest earned is $292.50.
        
             
        
        
        
Answer:
25 girls
Step-by-step explanation:
Let
x denote number of boys
and 
y denote number of girls
According to the statement that total 45 people came,
x+y = 45       => Eqn 1
And total paid amount was 175
So,
5x + 3y = 175     => Eqn 2
For solving, We will use the substitution method
So, from eqn 1
x = 45-y
Putting value of x in eqn 2
5(45-y) +3y = 175
225 - 5y + 3y = 175
-2y+225 = 175
-2y = 175-225
-2y = -50
2y = 50
y = 25
Putting y =25 in eqn 1
x+25 = 45
x = 45 - 25
x = 20
As y= 25 
So, 25 girls came to the dance ..

Answer:
≈ 4.89
Step-by-step explanation:
A = πr²
75 = 3.14 x r²
r² = 75 / 3.14 = 23.89
r = 4.89
