Answer:

  x = 8 1/3

Step-by-step explanation:

Put the known values into the equation and solve for x.

  f(x) = 3x -1

  24 = 3x -1 . . . . . use 24 for f(x)

  25 = 3x . . . . . . . add 1 to both sides

  25/3 = x . . . . . . divide both sides by 3

The input is x = 8 1/3.

Max bought 4 liters of fruit punch for a party.he will serve the punch in glasses that will hold 200 milliliters.how many full g
ss7ja [257]
Hello!
.
1 liter is equal to 1000 milliliter.
So,
4 L = 4000 mL
.
Max bought 4 liter or 4000 mL of fruit punch. To know how many glasses full of fruit punch can he serve, you just need to divide the amount of fruit punch he bought by the amount of fruit punch a glass can hold.
4 L / 200 mL
The dividend and the divisor have different unit so we must make them have the same unit.
4000 mL / 200 mL
= 20
.
Therefore, Max can make 20 full glasses of fruit punch for the party.

Molly Invests $8,600 into her son's college fund, which earns 3% annual interest
8_murik_8 [283]

Answer:

n= 13.8 years

Step-by-step explanation:

<u>First, we need to determine the daily interest rate:</u>

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

<u>Now, using the following formula we can determine the number of days and years:</u>

n= ln(FV/PV) / ln(1+i)  

n= ln(13,000 / 8,600) / ln(1.000082)

n= 5,039 days

<u>In years:</u>

n= 5,039/365

n= 13.8 years
