Durante un frente frío, la temperatura Canadá bajó de 7°C a -5°C ¿Cuántos grados bajo la temperatura
Anton [14]

Answer:

Durante el frente frío mencionado en el ejercicio, la temperatura de Canadá bajó:

  • <u>12°C</u>.

Step-by-step explanation:

Para obtener la cantidad de grados que bajó la temperatura en el caso mencionado, debes primero identificar la disminución en los grados positivos, es decir, cuando los grados Celsius llegaron a 0°C:

  • Diferencia entre 7°C y 0°C = <u>7°C</u>

En la operación matemática, solo restante la cantidad de grados necesarios a la temperatura inicial (7°C) para que la temperatura quedara en 0°C, donde obtenemos una diferencia de 7°C, ahora identificas la cantidad de grados que se necesitan para que la temperatura pase de 0°C a -5°C:

  • Diferencia entre 0°C y -5°C = <u>5°C</u>

Recuerda que como ya estamos hablando de diferencia, no necesitas señalar si los grados son negativos, solo identificamos el número de grados Celsius entre esas temperaturas mencionadas, por lo tanto, al final sumas las dos diferencias halladas y esa será la diferencia total entre las dos temperaturas dadas:

  • Diferencia entre 7°C y -5°C = 7°C + 5°C
  • <u>Diferencia entre 7°C y -5°C = 12°C</u>

Por lo tanto, durante el frente frío mencionado, <em><u>la temperatura en Canadá bajó 12°C</u></em>.

Finding the roots by completing the square
Andrej [43]
For y=x^2-6x-11

complete the square

so roots
set y=0
0=x^2-6x-11

group x terms
0=(x^2-6x)-11
take 1/2 of linear coefient (-6) and square it
-6/2=-3, (-3)^2=9
add positive and neative to inside of parenthasees
0=(x^2-6x+9-9)-11
complete square
0=((x-3)^2-9)-11
expand
0=(x-3)^2-9-11
0=(x-3)^2-20
add 20 to both sides
20=(x-3)^2
sqrt both sides
remember positive and negative roots

+/-2√5=x-3
add 3 to both sides
3+/-2√5=x

so
x=3+2√5 and 3-2√5

Karen is typing a report.she typed 3/8of the pages in the report in the morning and 2/5 of the pages in the afternoon.what fract
Karolina [17]
Simple...

you have \frac{3}{8} and \frac{2}{5}

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

\frac{3}{8} * \frac{5}{5} = \frac{15}{40}
and
\frac{2}{5} * \frac{8}{8} = \frac{16}{40}

So, subtract,

\frac{15}{40}&#10;-&#10; \frac{16}{40}

=- \frac{1}{40}

Thus, your answer.
