Answer
Let t be number of minutes since tap is opened
water is increased by 20 gallons of water per minute.
sugar increase rate of 3 pounds per minute
water :- W(t) = 350 + 10 t
sugar :- S(t) = 10 + 3 t
concentration
C(t) = 
at t = 15 minutes
C(15) = 
C(15) = 
C(15) = 0.11
at beginning t = 0 minutes
C(0) = 
C(0) = 
C(0) = 0.0286
C(15) > C(0)
hence, concentration is increasing as time is passing.
<span>In order to subtract larger numbers, such as these three digit numbers, it is beneficial to write the numbers in a single column in two rows. Place the larger number in the first row and the smaller one in the second row. After that, start subtracting the numbers starting from the right-most number; you may need to carry over numbers if the number on top is smaller than that at the bottom. The answer of this subtraction is 232.</span>
Answer:
n = 6
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
6n = 36 ( divide both sides by 6 )
n = 6
