La suma de dos enteros consecutivos es 25

1 answer:

5 0

X = el entero más pequeño

Entonces, el otro entero = x+1

Y podemos poner estos numeros en la equacion dado:

x + x+ 1 = 25

2x + 1 = 25

2x = 24

x = 12

x+ 1 = 13

Entonces, los enteros son 12 & 13.

An element with mass 730 grams decays by 27.6% per minute. How much of the element is remaining after 12 minutes, to the nearest

Korolek [52]

$\bf \qquad \textit{Amount for Exponential Decay}\\\\
A=I(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &730\\
r=rate\to 27.6\%\to \frac{27.6}{100}\to &0.276\\
t=\textit{elapsed time}\to &12\\
\end{cases}
\\\\\\
A=730(1-0.276)^{12}\implies A=730(0.724)^{12}$

A compressive uniform stress distributed on a rectangular areas of sides. located on the two opposite vertical/radial faces of s

postnew [5]

Answer:

Area = 0.019 m²

Step-by-step explanation:

stess = applied Force over Area

since stress = 0.987 MPa

and the force = 1.87 Kn

then Area = h * t

Q = F / (h * t)

0.987 mPa = 1.87 kN / (h* t)

since h * t = Area then 1.87 / 0.987

Area = 1.89 x 0.01 =

Area = 0.019 m²
