Adrienne invested a total of $2900.00 in two simple-interest money market accounts. Account A paid 3% annual interest and accoun

Butoxors [25]

Solving the system of equations, it is found that Adrienne invested $1,366.67 in account A and $1,533.33 in account B.

<h3>System of equations:</h3>

The variables are:

Variable A: Amount invested in account A.

Variable B: Amount invested in account B.

The equations are:

$a + b = 2900$

$0.03a + 0.05b = 133$

From the first equation:

$a = 2900 - b$

Replacing on the second:

$0.03a + 0.05b = 133$

$0.03(2900 - b) + 0.05b = 133$

$0.03b = 46$

$b = \frac{46}{0.03}$

$b = 1533.33$

Then, on the <em>first </em>equation:

$a = 2900 - b = 2900 - 1533.33 = 1366.67
$

Hence, Adrienne invested $1,366.67 in account A and $1,533.33 in account B.

dangina [55]

Answer:

The probability is 1/3, or in percent form, 33.3%.

Step-by-step explanation:

First, add up all the marbles. 3 plus 2 plus 1 equals 6 total marbles.

There are 2 yellow marbles out of 6 total marbles. Make it a fraction: 2/6.

Simplify the fraction by dividing by 2, to get 1/3, which is 33.3%.

Answer:

Option 4

Step-by-step explanation:

Coordinances for a three-dimensional coordinate system are (x, y, z).

The letter labeling each axis is always on the positive side.

The fourth option is correct because you move 3 units away from the 'x', 1 unit away from the 'y', then 2 units toward the 'z'.

Lin's goal is to drink 8 cups of water every day.She drank 37 ounces before lunch today.How much more water does Lin need to dri

Ahat [919]

Answer:

Lin needs to drink 27 ounces of water to reach her goal.

Step-by-step explanation:

1 cup = 8 fluid ounces.

8 cups = $8\times8=64$ ounces.

As of now Lin has drank 37 ounces of water. So, this means till now she has drank $\frac{37}{8}= 4.625$ cups of water.

In terms of ounces, she needs to drink 64-37=27 ounces of water to reach her goal.

Hence, the answer is 27 ounces or 8-4.625=3.375 cups.
