Isaac and Juanita are collecting apple to make an apple pie. Isaac picks up 3 apples every minute and Juanita picks up 5 apples every two minutes. If they need 40 apples for a pie, about how long will it take both of them to collect enough apples?

about 7 minutes (7.27 minutes to be exact)

Step-by-step explanation:

Since they are working as a team, we can combine the two rates to see how many apples they collect together per minute. Isaac collects 3 p/min while Juanita collects 2.5 p/min equaling 5.5 apples p/min. 40 apples divided by 5.5 equals 7.27 minutes.

Hope that helped!!

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

i think it is c, not positive though
