In the stock market an amazon stock share rose 4 and 1/2 points on Wednesday rose 3 and 3/8 points on Thursday and fell 2 and 1/

Vika [28.1K]

Answer:

In the three days the Amazon stock share rose by $5\frac{5}{8}$

Step-by-step explanation:

Given:

Amazon stock share

rose 4 and 1/2 points on Wednesday

rose 3 and 3/8 points on Thursday

fell 2 and 1/4 points on Friday

To find the overall change.

Solution:

The change in share on Wednesday is given as = $+4\frac{1}{2}$

The change in share on Thursday is given as = $+3\frac{3}{8}$

The change in share on Friday is given as = $-2\frac{1}{4}$

Thus, the over all change is given by:

$4\frac{1}{2}+3\frac{3}{8}-2\frac{1}{4}$

In order to combine mixed numbers, we will work the whole numbers and the fractions separately.

⇒ $(4+3-2)+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

⇒ $5+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

To combine fractions, we will take least common denominator.

The L.C.D. 2,4 and 8 = 8 as it is the least common multiple for all the denominators

So, we multiply the numerators with the corresponding numbers to make the denominators common.

⇒ $5+(\frac{1\times 4}{2\times 4}+\frac{3}{8}-\frac{1\times 2}{4\times 2})$

⇒ $5+(\frac{4}{8}+\frac{3}{8}-\frac{2}{8})$

Combining the numerators.

⇒ $5+\frac{4+3-2}{8}$

⇒ $5+\frac{5}{8}$

⇒ $5\frac{5}{8}$

The overall change for the three days can be given as : $+5\frac{5}{8}$

This means the share rose by $5\frac{5}{8}$

Hi!! I need some help with those exercises can anybody help me please !! Thanks you

elena55 [62]

Answer:

Step-by-step explanation:

(a+b)^2=a^(2)+2ab+b^(2)

(a-b)^2=a^(2)-2ab+b^(2)

13)

(x+2)^(2)-(x-1)^2

x^(2)+4x+4-(x^(2)-2x+1)

x^(2)+4x+4-x^(2)+2x-1

6x+3

15)

(x+5)^(2)-(x+1)^2

x^(2)+10x+25-(x^(2)+2x+1)

x^(2)+10x+25-x^(2)-2x-1

8x+24

What is the slope of the line that passes through the pair of points (-2.5,6.1) and (-2.5,3.1)

podryga [215]

(-2.5,6.1)(-2.5,3.1).....notice how ur x values are the same. This means that u have a vertical line which has an undefined slope.

IF ur y values would have been the same, u would have had a horizontal line which has a 0 slope.
