Answer:
B. x = 2√11
Step-by-step explanation:
The square of the length of the diagonal is ...
d² = 6² + 8² = 36 +64 = 100
Then the length of x is found from ...
d² +x² = 12²
x² = 144 -100 = 44 . . . . . subtract d²
x = √44 . . . . . . take the square root
x = 2√11
38.75 to one decimal place is 38.8
Answer:
3.5 years
Step-by-step explanation:
Each year, Louis earned
$1500×0.035 = $52.50
in interest.
The amount of interest that had been credited to his account at the time of withdrawal was ...
$1683.75 -1500.00 = $183.75
Then the length of time the money had been in the account was ...
$183.75/($52.50/yr) = 3.5 yr
_____
<em>Comment on the problem</em>
We have assumed the account earned simple interest. Given the neatness of the answer, we believe that to be a correct assumption.
Elemantary school so
area=legnth times width
to get greatest area, make legnth as close to width as possible in measure
to get least area, make legnth as far away from width as possible in measure
perimiter=2 times legnth+2 times width=2 times (legnth+width)
18=2 times (legnth+width)
divide 2
9=legnth+width
find closest and farthest
1+9 is farthest
4+5 is closest
areas=legnth times with
1 times 9=9
4 times 5=20
differnce is subtract
20-9=11
answe is 11
(note I didn't use decimals since the user is supposedly in elemenatry school)
