Answer:
Step-by-step explanation:
The world population currently is rising at a yearly rate of 1.35 percent. The nature of the growth is exponential. We will use the exponential growth formula, expressed as
A = P(1 + r)^t
Where:
A indicates the population after t years.
t symbolizes the number of years.
P is the initial population count.
r signifies the growth rate.
<pFrom the given data,
P = 6.1 × 10^9
r = 1.35% = 1.35/100 = 0.0135
t = 1
Hence,
A = 6.1 × 10^9(1 + 0.0135)^1
A = 6.1 × 10^9(1.0135)^1
A = 6182350000
The total number of people added would be
6182350000 - 6100000000
= 82350000
Answer:
The Framers provides the more affordable price, being $1.35 less expensive.
Step-by-step explanation:
I've Been Framed:
50% of $115 amounts to $57.5.
10% of $57.5 equals $5.75.
Subtracting gives $57.5 - $5.75 = $51.75.
Total: $51.75
The Framers:
30% off $120 results in $36.
After discount, $120 - $36 equals $84.
40% off $84 is $33.6.
Subtracting gives $84 - $33.6 = $50.4.
Price difference: $1.35
Al establecer un sistema de ecuaciones lineales, se determina que el total de obreros que contrató el ingeniero civil es 50.
Para descubrir cuántos obreros fueron contratados, se debe formular un sistema de ecuaciones lineales con dos ecuaciones y dos incógnitas, de la siguiente manera:
(1)
(2)
Donde:
M: representa la incógnita correspondiente al capital del ingeniero
x: simboliza la incógnita que denota el total de obreros
De la ecuación (1) podemos deducir:
(3)
Utilizando la ecuación (3) en la ecuación (2) podríamos calcular el valor de x (número de obreros):
El monto inicial del ingeniero, según la ec (3), sería:
Por lo que, el número de obreros contratados por el ingeniero es 50.

Answer:
The area calculates to 83.905 cm^3
Step-by-step explanation:
The overall ratio is 9 + 7 + 6 = 22
Thus, the side lengths are computed as follows;
9/22 * 44 = 18 cm
7/22 * 44 = 14 cm
6/22 * 44 = 12 cm
Heron’s formula allows us to determine the area of the triangle
First, we calculate s
s = (a + b + c)/2 = (18+14+12)/2 = 44/2 = 22
Heron’s formula can be expressed as;
A = √s(s-a)(s-b)(s-c)
where a, b, and c are 18, 14, and 12 respectively
Plugging in the values, we obtain;
A = √22(22-18)(22-14)(22-12)
A = √(22 * 4 * 8 * 10)
A = √(7,040)
A = 83.905 cm^3
