Phyllis invested $10,500 a portion earning a simple interest rate of 9(1/5)% per year and the rest earning a rate of 9% per year
Alenkinab [10]
Total investment  = $10,500

Let x = amount of first investment, and y the amount of the second investment.

First investment:
Interest rate = 9 (1/5)% = 0.092
Earned interest = 0.092x

Second investment:
Interest rate = 9% = 0.09
Earned interest = 0.09y

Total interest after one year is $957.00, therefore
0.092x + 0.09y = 957       
 or
1.0222x + y = 10633.33   (1)

Also,
x + y = 10500               (2)

Subtract (2) from (1).
0.0222x = 133.33
x = 6000
y = 10500 - x = 4500

Answer:
The first investment is $6,000 at 9 (1/5)% rate;
The second investment is $4,500 at 9% rate.

The Ferris wheel rotates 18° between successive cars being at the bottom.

 Angle inside a circle = 360°

 No of cars in a Ferris wheel = 20

 When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.

  Angle between two consecutive cars of Ferris wheel = 360/20 = 18°

 The Ferris wheel rotates 18° between successive cars being at the bottom.
