Spanish language Q&A Forum

I've seen both qué and cuánto in exclamatory sentences. I understand when it's clearly the number of something ( ¡Cuántos gatos! ) but when it's something less countable (e.g. "¡Qué orgulloso!" or "¡Cuánto orgulloso!" how do you tell which one to use?

Hi!! I would like to ask a question. So I'm doing a presentation in Spanish and i want to use the present perfect subjunctive in the last sentence. I want to say "I hope you enjoyed my presentation". The dictionary says that it's "espero que les haya gustado mi precentación", but isn't "haya" the verb form for "usted" and not "ustedes"? Several people are going to listen to me, so I want to address them all. What do I say? Is it "espero que les hayán gustado mi precentación" or "espero que les hayáis gustado mi precentación", or is it the sentence I wrote earlier?

Thank you in advance!!

Thank you for clarifying that this expression functions similar to the verb gustar.  I believe that the gustar structure is sometimes used with 3rd person plural, such as "Me gustan las películas."  Is there ever a time that "dar a alguien por algo" is used with 3rd person plural when followed by a plural noun?  For example, if I wanted to say "Now that my friend has retired, she has taken up new hobbies," would I still say, "Ahora que mi amiga se ha jubilado, le ha dado pasatiempos nuevos"?  Thank you!

¿Podría ser correcto usar ambas verbos en el pretérito indefinido para decir algo diferente? 

Por ejemplo "cuando vine a casa, ví el nuevo coche" en vez de "cuando venía a casa, ví el nuevo coche", para decir que lo ví inmediatamente después de que hubiera llegado (una acción cumplida, no interrumpida). 

Eso me parecería lógico y algo similar sí se puede usar en inglés, pero  ¿tiene sentido o es correcto en Español, o hay una forma distinta de decir algo así?

Espero que lo haya explicado suficiente claro... Muchas gracias.

In the quiz the answer was con Uds but I chose what I knew wasn't the right answer ustedes because the Uds would be  capitalized in the middle of the sentence. I'm pretty sure that's not correct either. Anyway, I don't think we need these kind of trick questions. My thought is that is a poorly created test question. That said, I'm interested if one ever capitalizes Uds in the middle of a sentence or if the capitalized Uds is standard for the abbreviation of usted and I am wrong here.

I'm reassured to see that even Mexican reporters sometimes conjugate their verbs incorrectly.
