We have 12 liters of 8% acid solution to which we add an unknown amount of liters (x) of 20% acid solution to make a 16% acid solution.
.08 * 12 +.20x = .16 * (12 +x)
.96 + .20x = 1.92 + .16x
.04x = .96
x = 24 liters of 20% acid solution must be added

Mademuasel [1]
Since we are already given with the total gross pay of the 6 employees, the amount that Mr. Jones should withhold from them for the social security tax that needs to pay will just be the product when $3,060 is multiplied by 7.05%. The answer should be $215.73.

Molly bought 12.5 yards of fabric for 4.50 dollars a yard to make dog beds.she uses2.5 yards of fabric for each dog bed.she sell
Mekhanik [1.2K]
12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric

she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds

each dog bed sells for 17.50.....5 * 17.50 = 87.50

87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==

Determine whether f(x) = 5x+1/x and g(x)= x/ 5x+1 are inverse functions explain how you know. please explain in steps or worded
Len [333]

Hello from MrBillDoesMath!

Answer:

No


Discussion:

If the functions are inverses, then f(g(x)) = x  for appropriate x. Consider x = 1.

g(1) = 1/ (5(1) + 1) = 1/6

f(g(1)) = f (1/6) =  5(1/6) + 1/ (1/6) = 5/6 + 6 = 6 5/6   <> 1

Conclusion: f(g(1)) <> 1 so the functions are not inverses


Thank you,

MrB

4960/3=1653.3
J=1657.3
K=1653.3
L=1649.3
