Answer:

30 liters of 50% acid solution!

Step-by-step explanation:

x-liters of 50% acid solution

We need a total of 60*0.6 liters of acid

    *36 liters of acid

0.5x+0.7(60-x)=36 (liters of acid)

Expand

0.5x+42-0.7x=36

0.2x=6

x=30

(To solve this informally you can think that you need equal amounts of both solutions since 0.6 is the average of 50% and 70% acid solutions)

Solve for x. (have to add extra letters so the question works)
zloy xaker [14]

Answer:

x=11°

Step-by-step explanation:

-Sum of angles of a triangle should alway be 180 degrees

35+110+2+3x=180

-Add all known values

147+3x=180

-Subtract 147 from both sides

3x=33

-Isolate x by divind both sides by 3

x=11°

Find the first term and the explicit formula a12=1/32 and r=1/2
Alexxx [7]

Answer:

see explanation

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

Given a_{12} = \frac{1}{32} and r = \frac{1}{2}, then

a (\frac{1}{2}) ^{11} = \frac{1}{32}, that is

\frac{a}{2^{11} } = \frac{1}{32}

\frac{a}{2048} = \frac{1}{32} ( cross- multiply )

32a = 2048 ( divide both sides by 32 )

a = 64 ← first term

Thus the explicit formula is

a_{n} = 64 (\frac{1}{2}) ^{n-1}
