The altitude is the mean proportional between the left and right parts of the hyptenuse
20/m = m/8
m² = 20 · 8
m² = 160
m = √160
m = 4√10
14 over 4509 would be an equvilent fraction
To find liters from meters, multiply the meters by 1000. 1 meter equals 1000 liters. So, the answer would be 375000 from 3,750.
P.S. IF you meant 750, then it's 750000
If the question is asking if only one isnt insured, the chances are 1/12.
If the question is asking if at least one isnt insured, the chances are 1/4.
X+ 3y = 1 -----(first equation)
-2x+7 = -23 ---(second equation)
-2x = -23-7
x = 30/2
x = 15
Now, Substitute the value of x in first equation,
15 + 3y = 1
3y = 1 - 15
y = -14/3
In short, Final Answers are: x = 15 & y = -14/3
Hope this helps!
