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:

<em>The change in share on Wednesday is given as = +4\frac{1}{2}</em>

<em>The change in share on Thursday is given as = +3\frac{3}{8}</em>

<em>The change in share on Friday is given as = -2\frac{1}{4}</em>

Thus, the over all change is given by:

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

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

⇒ (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.

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

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}

Suppose you have 13 tubes of paint. How many distinct color groupings can you make with your paint?
anzhelika [568]

Answer:

32767 distinct color grouping

Step-by-step explanation:

Given data:

Total tube is 13

for distinct color, group can be 1,2,3,4,.... 15

For total number of ways we have following relation

^nC_0 +^nC_1 +^nC_2 + .......^nC_n = 2^n

here n = 13 so we have

^15C_0 +^15C_1 +^15C_2 + .......^15C_{15} = 2^15

for at least one

= 2^{15} - 1

= 32768 -1

= 32767 distinct color grouping

After a storm, two street lights with the same length are leaning against each
Ray Of Light [21]

Answer:

c = 4.79 feet

Step-by-step explanation:

Given question is incomplete without a picture; find the question with the attachment.

Two poles AD and DB of same length are leaning against each other.

Distance between the poles (AB) = 45 feet

m(∠ADB) = 180°- (60 + 50)°

               = 70°

By sine rule,

\frac{sin50}{AD}=\frac{sin70}{45}=\frac{sin60}{DB}

AD=\frac{45\times (sin50)}{sin70}

      = 36.68 ft

Similarly,

DB = \frac{45\times sin60}{sin70}

     = 41.47 ft

Now c = DB - AD

           = 41.47 - 36.68

           = 4.79 feet
