Marissa owns 135 shares of stock. Her dividend is $0.50 per share. How many shares can she buy of a different stock selling for

belka [17]

Answer:

- If the new stock is selling for $11 per share, Marissa can buy 6 shares.

- If the new stock is selling for 11 cents per share, Marissa can buy 613 shares.

Step-by-step explanation:

The question is not totally clear with the last statement.

- How many shares can she now buy of a different stock, selling for $11 per share?

- How many shares can she now buy of a different stock, selling for 11 cents per share?

Marissa has 135 shares of stock

Each share has a dividend of $0.50 per share,

The dividend from her 135 shares of stock would be 135 × $0.5 = $67.5

How many shares can she now buy of a different stock, selling for $11 per share?

= ($67.5/$11) = 6.14 ≈ 6 shares

If the new stock is selling for 11 cents per share, the number of shares she can buy = (67.5/0.11) = 613.6 ≈ 613 shares

Hope this Helps!!!

To find the slope, you use the slope formula (m):

$m=\frac{y_2-y_1}{x_2-x_1}$ and plug in the two points

(-3, 4) = (x₁, y₁)

(2, -1) = (x₂, y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-1-4}{2-(-3)}$ [two negatives cancel each other out and become positive]

$m=\frac{-1-4}{2+3}$

$m=\frac{-5}{5}$

m = -1 The slope is -1

Beakers X and Y contain some water. If 50 ml of water is transferred from Beaker X

eduard

Answer:

140 ml

Step-by-step explanation:

Let x be the amount of water in Beaker X and y be the amount of water in Beaker Y.

Then we get following equations:

First part

x - 50 = 3/7(y + 50)
7x -350 = 3y + 150
7x = 3y + 500

Second part

x + 100 = 4(y - 100)
x + 100 = 4y - 400
x = 4y - 500

Substitute x in first equation:

7(4y - 500) = 3y + 500
28y - 3500 = 3y + 500
28y - 3y = 500 + 3500
25y = 4000
y = 4000/25
y = 160 ml

Then finding x:

x = 4*160 - 500
x = 640 - 500
x = 140 ml

Initial amount of water in Beaker X is 140 ml, in Beaker Y is 160 ml
