A student finds the sum of the angle measures in an octagon by multiplying 7 • 180°. What is the student's error?

Lostsunrise [7]

The student should compute 6*180 = 1080 because of the formula

S = 180(n-2)

We have n = 8 sides which leads the n-2 part to become n-2 = 8-2 = 6

A bag of corn tortilla chips costs 2.89 after a 15% discount. What is the original price?

Montano1993 [528]

Answer:

3.4

Step-by-step explanation:

Let the original price of the bag be = P, the selling price =2.89 after a 15% discount,

Then, Selling price= Original price- Discount on original price

$2.89=P-P(0.15)$

$2.89=P(1-0.15)$

$2.89=0.85P$

$P=\frac{2.89}{0.85}$

$P=3.4$

Thus, the original price was 3.4.

ariel is saving money for a new computer that costs $650. she has $150, which she puts into an account. then she adds $25 each w

Oksanka [162]

20 weeks

The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks

Una persona camina 7 kilómetros hacia el norte, después 3 kilómetros hacia el este y, luego, 3 kilómetros hacia el sur. ¿A qué d

qaws [65]

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

$\vec r_{1} = 7\,\hat{j}\,[km]$

(ii) Después 3 kilómetros hacia el este:

$\vec r_{2} = 3\,\hat{i}\,[km]$

(iii) Y luego, 3 kilómetros hacia el sur:

$\vec r_{3} = -3\,\hat{j}\,[km]$

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

$\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3}$ (1)

$\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km]$

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

$\|\vec R\| = \sqrt{3^{2}+4^{2}}$

$\|\vec R\| = 5\,km$

La persona está a 5 kilómetros con respecto al punto de partida.
