Live Fund receive [tex]\bold{\$2500 N}[/tex] it they sold half thier holding in Marks Brothers.

Solution:

Given: Sale price of Live Fund holding is 5000 dollar

To find: Amount that Live Fund will get if they sell half of their holding in Marks Brothers.

Assume the total holdings held by Live Fund in Marks Brothers as N

Therfore, half the number of shares or (half the holdings) of Live Fund will be [tex]\frac{N}{2}[/tex].

Thus, if each share is valued at [tex]\$5000[/tex], then the total value of the number of shares sold will be as follows,

[tex]\Rightarrow5000\times\frac{N}{2}\text{ dollars }\rightarrow\frac{5000\times N}{2}\text{ dollars }[/tex]

Answer: 40,320

Step-by-step explanation: Let's say that there is person A,B,C,D,E,F,G,H. and 8 chairs. For the first chair, 8 different people could potentially sit in it, making 8 different possibilities. No matter who sits there, the logic follows the next table. However, since one person is sitting in the first chair, there are 7 different possibilities about who would be sitting in the second chair. If you multiply the two together, there are 56 different possibilities just for the first and second chair. For the third chair, there are 6 different possibilities about whom could sit. Multiply 56*6 and you get 336 possibilities. Keep multiplying out and you get a grand total of 40,320 different arrangements!

Answer:

X-Intercept: (1.2,0)

Y-Intercept (0,.75)

Step-by-step explanation:

If you want fraction form then the

X-Intercept: (6/5,0)

Y-Intercept (0,3/4)

To find the x intercepts, you have to plug y=0 into the equation. After you plug in y=0, you get the equation 5x-9=-3 and once you solve that, you find that the x intercept = 1.2

Likewise, to find the y intercepts, you would plug x=0 into the equation. Once you do that, you get the equation -9=-8y-3 and when you solve for y you get an intercept of 3/4

Answer:

a) $19,023.63

b) $19,046.02

c) $19,061.13

d) $19,068.74

Step-by-step explanation:

P = 15000

t = 6

r = 0.04

a) Compounded semiannually means 2 times per year, so n = 2.

A = 15000 (1 + 0.04/2)^(2×6)

A = 19023.63

b) Compounded quarterly means 4 times per year, so n = 4.

A = 15000 (1 + 0.04/4)^(4×6)

A = 19046.02

c) Compounded monthly means 12 times per year, so n = 12.

A = 15000 (1 + 0.04/12)^(12×6)

A = 19061.13

d) Compounded continuously means we use the continuous equation:

A = 15000 e^(0.04×6)

A = 19068.74

Tim ran a total of 3000 meters, which is three times the distance that Eric ran. By dividing Tim's distance by three, we find that Eric ran 1000 meters.

To solve for the distance Eric ran, we need to first determine the total distance Tim ran and then divide that by three as Tim's distance is three times longer than Eric's.

Tim's speed is 300 meters per minute, and he ran for 8 minutes before having 600 meters left to run. To calculate the distance Tim ran:

Therefore, the distance that Eric ran was 1000 meters.

Answer:

Total savings  = $63  +  12 ( m)  

: m  = number of driveways shoveled

Step-by-step explanation:

Here, the money earned for each road David shovels = $15

The number of driveway shoveled by David = 12

The total money saved  David has after he is done with his work = $243

Now, The number of money saved by shoving 12 driveways  

= 12 x ( Money earned by shoveling 1 driveway)

= 12 x ( $15) = $ 180

Total savings  = His previous savings  + Money earned from Shovel work

⇒  $243  =   His previous savings + $ 180

⇒ His previous savings = $243  - $180 = $63

Now, we can write his total savings as:

Total savings  = $63  + 12 ( m)  

: m  = number of driveways shoveled

Answer:

The amount of time it takes to ride 26 miles is 2.89 hours.

Step-by-step explanation:

Given : You ride your bike at 9 miles per hour.

To find : How long it will take you to ride 26 miles ?

Solution :

The equation given is [tex]9\times t=26[/tex]

Using distance formula,

[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]

According to formula t represent the time taken to cover the distance.

Your speed in miles per hour is 9 miles per hour.

The number of miles you've traveled so far is 26 miles.

Solving the equation,

[tex]9\times t=26[/tex]

[tex]t=\frac{26}{9}[/tex]

[tex]t=2.89[/tex] hours

The amount of time it takes to ride 26 miles is 2.89 hours.

Answer:

Personal emails = 274 emails.

Step-by-step explanation:

Given,

Business and personal emails = 578

Therefore, there are two types of emails. Again, there are 30 fewer emails in personal emails.

The total number of emails after deducting the fewer personal emails = (578 - 30) = 548 emails.

Therefore, each type of email, according to the question = (548/2) = 274 emails

So, personal emails are 274. Business emails = (274 + 30) = 304 emails.

The problem involves setting up and solving an equation based on the information given: that the number of personal emails is 30 fewer than the number of business emails, and the total is 578. By doing this, we deduce that there are 274 personal emails.

The problem tells us that there is a total of 578 emails, both business and personal combined. Furthermore, we know that there are 30 fewer personal emails than business emails. We can use this information to create an equation and solve for the number of personal emails.

First, we can represent the number of business emails as 'x'. So, the number of personal emails would be 'x - 30'. The sum of the business and personal emails is 578, so our equation is x + (x - 30) = 578.

Solving this equation gives us: 2x - 30 = 578, 2x = 608 and finally x = 304. This is the number of business emails. To get the number of personal emails, you subtract 30 from the total business emails (as the question states). So, there are 304 - 30 = 274 personal emails.

Answer:

For the given function, Slope is [tex]\frac{7}{9}[/tex] and y-intercept is -2.

Step-by-step explanation:

The given function in x is :

    [tex]k(x)=\frac{7}{9}x-2[/tex]              .....1

Since, we know that the general form of equation of a line is :

     [tex]y=mx+c[/tex]                             .....2

where, y is the dependent variable, x is independent variable, m is the slope and c is the y intercept of the line.

On comparing equation 1 and 2, we get :

[tex]k(x) = y[/tex];

[tex]m = \frac{7}{9}[/tex]; and

[tex]c=-2[/tex];

Thus, we can conclude that

slope of function is [tex]\frac{7}{9}[/tex] and y-intercept is -2.

Step-by-step explanation:

4x+(x-y/8)=17

2y+x-(5y+2/4)=2

-----------------------

4x+x-y/8=17

5x-y/8=17

40x-y=136

y=40x-136

------------------

2y+x-5y-2/4=2

2y-5y+x-1/2=2

-3y+x=2+1/2

-3y+x=4/2+1/2

-3y+x=5/2

-3(40x-136)+x=5/2

-120x+408+x=5/2

-119x=5/2-408

-119x=5/2-816/2

-119x=-811/2

119x=811/2

x=(811/2)/119

x=(811/2)(1/119)=811/238

y=40(811/238)-136

y=16220/119-136

y=36/119

x=811/238, y=36/119.

Dimension of rectangular parking lot is width = 112.882 feet and length = 132.882 feet

Given that  

Area of rectangular parking lot = 15000 square feet

Length is 20 feet more than the width.

Need to find the dimensions of rectangular parking lot.

Let assume width of the rectangular parking lot in feet be represented by variable "x"

As Length is 20 feet more than the width,

so length of rectangular parking plot = 20 + width of the rectangular parking plot

=> length of rectangular parking plot = 20 + x = x + 20

The area of rectangle is given as:

[tex]\text {Area of rectangle }=length \times width[/tex]

Area of rectangular parking lot = length of rectangular parking plot [tex]\times[/tex] width of the rectangular parking

[tex]\begin{array}{l}{=(x+20) \times (x)} \\\\ {\Rightarrow \text { Area of rectangular parking lot }=x^{2}+20 x}\end{array}[/tex]

But it is given that Area of rectangular parking lot = 15000 square feet

[tex]\begin{array}{l}{=>x^{2}+20 x=15000} \\\\ {=>x^{2}+20 x-15000=0}\end{array}[/tex]

Solving the above quadratic equation using quadratic formula

General form of quadratic equation is  

[tex]{ax^{2}+\mathrm{b} x+\mathrm{c}=0[/tex]

And quadratic formula for getting roots of quadratic equation is

[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

In our case b = 20, a = 1 and c = -15000

Calculating roots of the equation we get

[tex]\begin{array}{l}{x=\frac{-(20) \pm \sqrt{(20)^{2}-4(1)(-15000)}}{2 \times 1}} \\\\ {x=\frac{-(20) \pm \sqrt{400+60000}}{2 \times 1}} \\\\ {x=\frac{-(20) \pm \sqrt{60400}}{2}} \\\\ {x=\frac{-(20) \pm 245.764}{2 \times 1}}\end{array}[/tex]

[tex]\begin{array}{l}{=>x=\frac{-(20)+245.764}{2 \times 1} \text { or } x=\frac{-(20)-245.764}{2 \times 1}} \\\\ {=>x=\frac{225.764}{2} \text { or } x=\frac{-265.764}{2}} \\\\ {=>x=112.882 \text { or } x=-132.882}\end{array}[/tex]

As variable x represents width of the rectangular parking lot, it cannot be negative.

=> Width of the rectangular parking lot "x" = 112.882 feet  

=> Length of the rectangular parking lot = x + 20 = 112.882 + 20 = 132.882

Hence can conclude that dimension of rectangular parking lot is width = 112.882 feet and length = 132.882 feet.

The first plant produces 5x + 26 more items daily than the second​ plant

Given that , A company has two manufacturing plants  

The daily production levels of one company is 7x + 19 items  

And daily production levels of another company is 2 x - 7 items

To find the number of items first plant produce more than the second plant, wed need to subtract the number of items produced by second plant from the the number of items produced by first plant.

Extra items produced by 1st plant = daily production of 1st plant - daily production of 2nd plant

Extra items produced count = 7x + 19 – (2x – 7)

The slope intercept  of the given line equation AB is [tex]y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]

Step-by-step explanation:

Here,the two given point s are A ( -9,-2) and B (1,3).

Now, the slope m of the line AB  =  [tex]= \frac{y_2 - y_1}{x_2 -x_1}[/tex]

[tex]\implies m = \frac{3 - (-2)}{1 - (-9)}  = \frac{3+2}{1+9}  = \frac{5}{10}  = \frac{1}{2}[/tex]

or, the slope of line AB = 1/2

Now, the POINT SLOPE FORM of any equation with point (x0,y0) and slope m is given as :

y - y0 = m (x -x0)

So, the line equation of AB is given as :

[tex]y - 3 = \frac{1}{2}  ( x-1)\\\implies y  =3 +  \frac{1}{2}  ( x-1)\\or, y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]

SLOPE INTERCEPT form is y = mx + c

Hence, the slope intercept  of the given line equation AB is [tex]y  = \frac{1}{2}  ( x)- \frac{5}{2}[/tex]

Procedures must be made simpler in order to attain uniformity in efforts, expenses, and time. Variety and variation that is unnecessary, damaging, and unproductive are eliminated.

Given an equation  [tex](-xy^{4} b^{2} )^{4}[/tex]  in this, we need to find a monomial in standard form which can be optimized after putting the power back at every variable. hence,

[tex](-xy^{4} b^{2} )^{4}[/tex]  =  (-x)⁴(y⁴)⁴ (b²)⁴

=   x⁴y¹⁶b⁸

Therefore,  a monomial in the standard form  [tex](-xy^{4} b^{2} )^{4}[/tex] is   x⁴y¹⁶b⁸.

The student is asking about the calculation of odds against a rugby team winning its next match given a certain probability of winning. First, we need to understand the probability of the team not winning (losing or drawing) because the odds against the team winning would be the ratio of it losing to it winning. Since the probability of winning is given as 3/8, the probability of not winning is 1 - 3/8 = 5/8. The odds against the team winning are therefore expressed as the ratio of the probability of not winning to the probability of winning, which is 5/8 to 3/8, or simply 5:3 when converted into odds format.
