Answer:
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 can't see it rn.
*Added explanation for the 1st one*
1st one
so we know that the perimeter is 24.
What I do is just check out all the possibilities
i started off with making an even square
24/4=6
6*6=36
then I tried again
but with 1 as my width
1*2 sides=2
24-2=22
22/2=11
11*1=11 which is the smallest
It's kinda hard to explain since it really just is taking some time to find the smallest area combination.
brainliest?
