I think the two datas have somewhat similar distribution.
31/20, or turned into a mixed fraction, is 1 11/20kg. Hope this helps!
Answer:2.5
Step-by-step explanation:
Answer:
If the battery starts completely charged then after one hour it will be at 80% so at two hours it will be at 60. and there is 60 minutes in one hour so it goes down 10% in 30 minutes so it goes down 5% in 15 so it goes down 2.5% in 7.5
We know: length of a rectangle is 7m less than three times the width.
So let's set the length to l, width to w.
And we can get that l = 3w-7.
We also know that the area of the rectangle is 66 m^2.
Thus, l*w= 66.
So we have:
function 1: l=3w-7
function 2: l*w=66
plug function 1 to 2.
(3w-7)*w=66
3w^2-7w-66=0
w=6 and -11/3.
And the width of a rectangle can not be negative.
So: w=6.
Plug w=6 back to function 1 or 2, either way is correct and can give you the length. In this case, I will plug it back to function 1.
l=3*6-7=11.
So: the width of the rectangle is 6, and the length of the rectangle is 11.
