Present Tense Conjugation Help

[Jessica]

1) ¿Quién ______ (cortar) el césped?
What do you put in the blank? Which subject is it?
Is it....
yo- corto
tú- cortas
ella--V
él -corta
Ud.---^
nosotros-cortamos
nosotras--^
ellas--V
ellos-cortan
Uds.--^

2) Translate this: ¿Hace Ud. la cama todos los días?
Does it mean "Do you make your bed everyday?

3) Is this right? ¿Lavas (lavar) tú los platos?
Do you conjugate "lavar" into lavas because of the tú? I'm sure this is right, but I want to make sure.

4) Is this right? Yo paso (pasar) la aspiradora a veces.
I know that you conjugate pasar into paso because of the yo. Is that the right spelling? Or is pasar an irregular verb? I don't think it is, though.

1) ¿Quién ______ (cortar) el césped?

Fist thing popped ¿Quien va a cortar
Also ¿Quien corta el cesped (hoy)?

2) ok, fine

Is this right? ¿Lavas (lavar) tú los platos?
Again, first solution was ¿Vas a lavar...?

Lavas is right, sure. It's a bit more pushy

4) Is this right? Yo paso (pasar) la aspiradora a veces.

Right, good student. A veces, yo paso la aspiradora. sounds more natural to me, dunno why. This sentence appears in portorican spanglish in the NY area:
vacunar la carpeta-pasar la aspiradora-vacuum the carpet (spanglish-spanish-english).

All the sentences take the present tense, Jessica. You made correct choices on them all (but didn't provide a guess for the first).
