There are a few questions that I need help with. any answers would be a great.

1. 11 cm sq

2. $48

3. 2,697,986

4. (can't see the whole thing)

Step-by-step explanation:

1st one

I just tested out all the possibilities and that is the smallest it can get

2nd one

First, we add up 1/4 and 1/3

1/4 = 3/12

1/3 = 4/12

3/12+4/12 is 7/12 this is how much money she spent in total

5/12 is remaining which we know is $20 so if we find what 1/12 is we can multiply to find the original. 20/5=4. 1/12 = 4 now we do 4*12 which is 48 so she had $48 originally.

3rd one

This one the wording is weird, so they are just asking what minus 2 700 000 is 2014. We can just do 2,700,000-2014 which is 2,697,986

4th one

I cant see the whole problem, ill be glad to help but I cant see it rn.

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
