Reggie invests $12,000, part at 7% annual interest and part at 8.5% annual interest. how much is invested at each rate if reggie
Vika [28.1K]

Let us say that:

x = invested at 7%

y = invested at 8.5%

and that:

<span>x + y  = 12,000</span>

We can also say that:

0.07 x + 0.085 y = 900

 

Therefore:

0.07 x + 0.085 (12000 – x) = 900

0.07 x + 1020 – 0.085 x = 900

- 0.015 x = -120

x = $8000

 

so y is:

y = 12000 – 8000

y = $4,000


$8000 is invested at 7% annual interest while $4000 is invested at 8.5%

Tara has two bags of marbles the first bag contains 8 red marbles four blue marbles three green marbles the second bag contains
Lesechka [4]

Answer:

2/27

Explanation:

The two events, drawing a blue marble out of each bag, are independent. This means to find the probability of both occurring, we multiply them.

In the first bag, there are 5 blue marbles out of 15 total. This makes the probability 5/15, or 1/3.

In the second bag, there are 2 blue marbles out of 9 total. This makes the probability 2/9.

Together, the probability of both events happening are:

1/3(2/9) = 2/27
