Answer:

25%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

Here, new number = 30, and old number = 24.

percent change = (30 - 24)/(24) * 100%

percent change = 6/24 * 100%

percent change = 0.25 * 100%

percent change = 25%

La matemática financiera experimentó grandes avances con la creación de la banca y los negocios creados por los emprendedores. E
Tresset [83]

Answer:

c = \frac{1}{10}

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

C = f+cm

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

3000=f+c15000, 3500=f+c20000

Si restamos la segunda ecuación de la primera, tenemos que

3500-3000 = f-f+(20000c-15000c)

Luego

500 = 5000c

Entonces c = \frac{500}{5000} = \frac{1}{10}

Si tomamos la primera ecuación, tenemos que 3000-\frac{15000}{10} = f. Es decir,

3000-1500 = f = 1500

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.

What is the greatest common factor of the polynomial's terms?
Alinara [238K]

Step-by-step explanation:

Write the prime factorization of each term:

9r⁵s = 3² × r⁵ × s

6r⁴s² = 2 × 3 × r⁴ × s²

12r²s = 2² × 3 × r² × s

The greatest common factor will have all the common factors raised to their lowest exponent.

So all three terms have 3, r, and s as factors.  The lowest exponent of 3 is 1.  The lowest exponent of r is 2.  The lowest exponent of s is 1.

GCF = 3 × r² × s

GCF = 3r²s

Factor out the GCF:

9r⁵s + 6r⁴s² − 12r²s

3r²s (3r³ + 2r²s − 4)
