liraira [26]

Answer: 2285.71

Step-by-step explanation:

Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.

r = R/100 = 5%/100 = 0.05 per year.

Solving the equation:

P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143

If DF = 170, find the value of x. Then find DE and EF.<br> DE=3x + 20<br> EF=2x + 40
Julli [10]

9514 1404 393

Answer:

  DE = 86

  EF = 84

Step-by-step explanation:

We assume that point E lies on segment DF, so that ...

  DE + EF = DF

  (3x +20) +(2x +40) = 170

  5x = 110 . . . . . . . . . . . . . . . collect terms, subtract 60

  x = 22 . . . . . . . . . . . . divide by 5

  DE = 3×22 +20 = 66 +20 = 86

  EF = 2×22 +40 = 44 +40 = 84

There were 567 people at a concert when a band started playing. After each song, only one-third of the people stayed to hear the
emmasim [6.3K]
To write the function correctly, it is important to assign variables correctly and understand the situation of the problem clearly. For this, we let y the number of people and x as the number of songs played.

At x = 0   y = 567
at x = 1   y = 567 - 567(1/3)
at x = 2   y = 567 - 567(1/3)(1/3)
at x = 3   y = 567 - 567(1/3)(1/3)(1/3)

Therefore, the number of people left after x songs would be represented by the equation:

y = 567 - 567(1/3)x
y = 567 ( 1- x/3 )
