You need a 35% alcohol solution. On hand, you have a 715 mL of a 20% alcohol mixture. You also have 90% alcohol mixture. How muc

asambeis [7]

Answer:

90% Solution

Step-by-step explanation:

5% of 90 + 90% of x = 75% of (90 + x)

5×90/100 + 90x/100 = 75×90/100 + 75x/100

Or 90x/100 - 75x/100 = 75×90/100 - 5×90/100

Or 15x/100 = 90×70/100

Or X = 420ml

You Will Need ML Of The 90% Solution To Obtain ML Of The Desired 75% Solution.

Write down in terms of n an expression for the nth term of the following sequence. A) 25,20,15,10,5

ExtremeBDS [4]

Answer:

(30-5n)

Step-by-step explanation:

The given sequence is :

25,20,15,10,5

Here,

First term, a = 25

Common difference = 20-25 = -5

We need to find the nth term of the given sequence. The formula for the nth term is given by :

$a_n=a+(n-1)d\\\\a_n=25+(n-1)(-5)\\\\=25-5n+5\\\\=30-5n$

So, the nth term of the above sequence is (30-5n).
