In the sentence given, the "personal a" is:

Not necessary

So the complete sentence is:

¿Entiendes las palabras de tu profesora?

<h3>What is the "personal a"?</h3>

This is Spanish grammar exercise. The "personal a" is an "a" that precedes a specific person or a person that is used as a direct object.

In the sentence given, the "a" is not used because the direct object is "las palabras" which means "the words" and it is not a person.

For example:

Adoro a mi mamá.
Le llegó una carta a mi vecina.

Alla [95]

The total equivalent units in the weighted-average method used will be 316800 and 304200 respectively.

<h3>What is weighted-average method?</h3>

The weighted-average method simply uses the weighted average to determine the cost of goods sold.

From the complete question, the total equivalent units for material cost will be:

= $300000 + $16800

= $316800

The total equivalent units for conversion will be:

= $300000 + $4200

= $304200

two objects, x and y, accelerate from rest with the same constant acceleration. object x accelerates for twice the time as objec

Nana76 [90]

Answer:

X has travelled 4 times as far as Y

X is moving 2 times as fast as Y

Explanation:

Because x=1/2at²(get rid of the first portion of x=vt+1/2at² because initial v is 0 which multiplies to 0). If the acceleration is set to for example 10 (keep this constant for both X and Y) and we use t=1 and t=2 for time (as the time travelled of X is twice that of Y). Plugging this into the equation, at t=1, x=4. At t=2, x=20. 20 is four times greater than 5, so X has travelled 4 times as far as Y.

To find the difference in speed between the two objects, use the equation $v_{f}=v_{0} +at$ . Since the initial velocity is 0, that part can just be removed from the equation. With v=at, it is easy to see that if the time plugged in is twice for one than the other (and the acceleration is the same for both), the final result will be twice of the other as well. For example: If the acceleration is 10 again for both, then v=10t. If t is 1, the velocity is 10. If t is 2, the velocity is 20.
