IM GIVING BRAINLIEST AND 100 POINTS NO JOKE. PLEASE HELP
Sav [38]

Answer:

i hope this helps

Step-by-step explanation:

if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast

70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.

Then it also says, "of those 70% of people, 25% eat cereal"

That means 25% of those 70 people eat cereal, or 1/4 of that population does.

0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)

and of the 17.5 people, 30% of them eats it with extra sugar.

so 30% of 17.5 people is 5.25.

that means that there are 5.25 people who eat cereal with extra sugar.

i hope this helps, it took a while for me to try to help with this

i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)

(0.25x 0.7) = 0.175

A computer scans every 2.75 days and another scans every 3.5 days
Brut [27]

Answer:

Alright, so we have to find the LCM of 2.75 and 3.5.

A good start would be to multiply them together to get 9.625, but we want a whole day!

This would be every 77 days :)
