scoundrel [369]

Answer:

let w = amt of water required

:

An equation based on the the percent water, an 80% solution is 20% water.

 

.20(320-w) + w = .50(320)

64 - .2w + w = 160

.8w = 160 - 64

w = 96%2F.8

w = 120 gal of water to produce 320 gal of 50% antifreeze

:

320 - 120 = 200 gal of 80% solution

Water: _120___ gallons

Which of the following is equivalent to log408 rounded to three decimal places?
il63 [147K]

The answer is: 0.564

The explanation is shown below:

1. To solve this problem you must apply the following proccedure:

2. You have the logarithm expression:

log40(8)=x

3. First, you must apply the following property:

a^{loga(x)} =x

4. Therefore, you have:

40^{log40(8)}=40^{x} \\ 8=40^{x}

5. By applying logarithm on both sides, you have:

log(8)=log(40^{x} )

6. By applying the property log(a)^{b} =blog(a):

log(8)=xlog(40)

7. Solve for x:

x=log(8)/log(40)\\ x=0.564
