Resuelve los problemas de una bodega que exporta tomates al extranjero

Dovator [93]

Answer:

1. 34.42 Toneladas

2. 28.640 toneladas

3. 38 toneladas

4. $\frac{15}{10}$ o $1\frac{5}{10}$

5. $\frac{16}{6}$ o $2\frac{4}{6}$

6. $\frac{8}{4}$ o $2$

1.1 Solucioné el problema convirtiendo el .25 en fracción.

2.1 Conviertes el denominador en el mismo buscando el minimo comun multiplo

3.1 0.099

$\frac{1}{4}$

$\frac{1}{3}$

$\frac{2}{3}$

0.7

0.75

1.1

$\frac{3}{2}$

Step-by-step explanation:

Acuerdate que para solucionar las fracciones mixtas solo tienes que dividir el denominador al nominador, por ejemplo en si tienes $\frac{10}{3}$ entonces el 3 cabe 3 veces en el 10, y sobra 1, entonces quedamos que en mixta la fracción sería $3\frac{1}{3}$

Entonces una vez que recordamos eso, podemos resolver los problemas de fracciones sin ningún problema vamos a resolver la número 4:

$\frac{8}{10} +\frac{7}{10}$

Como el denominador es igual, sólo sumamos el nominador:

$\frac{8+7}{10}$

$\frac{15}{10}$

Cómo el 10 cabe 1 vez en el 15, tenemos un entero y sobran 5:

$1\frac{5}{10}$

[25 POINTS] The approximate change in the value of f(x) = sqrt(2(x-1)) at x = 3 using differentials with dx = 0.01 is

otez555 [7]

Answer:

$\frac{1}{200}$

Step-by-step explanation:

<u>Find the derivative of the function when x=3</u>

<u /> $y=\sqrt{2(x-1)}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(x-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(3-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(2)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{4}}$

$\frac{dy}{dx}=\frac{1}{2}$

Since the change in the value of the function is $dy$ and we know that the change in x is $dx=0.01$ , then we have:

$\frac{dy}{dx}=\frac{1}{2}$

$dy=\frac{1}{2}dx$

$dy=\frac{1}{2}(0.01)$

$dy=\frac{1}{200}$

Therefore, the 2nd option is correct

Can someone tell me the answer to this plz

Tpy6a [65]

M8 =43.
Reason:
134+ M8 =180(degrees). This is because angles on a straight line =180 (degrees)

180-134=M8
Therefore:
M<8 =180-134= 43 (degrees)

Hope this helps and makes sense.

Please mark as a brainliest (crowns)
