8people paint 4 walls in 40 min. how long will it take for 10 people to paint 7 walls

Hey!

Hope this helps...

Assuming that the each person from the group of 10 people will take as long as each person from the group of 8 people took (which is 1.25 minutes per person), it is estimated around  87.5 minutes the group of 10 people will take to paint 7 walls?

P.S. If this is a multiple choice question, can you please state the possible answers?  But if this is a short answer question, I'm pretty sure this is correct...

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
