[tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex]

Step-by-step explanation:

We need to find the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex]

We can solve it as follows :

[tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))\\\\=(\dfrac{x+3x-2x}{4})+1-\dfrac{2}{3}\\\\=\dfrac{2x}{4}+\dfrac{1}{3}\\\\=\dfrac{x}{2}+\dfrac{1}{3}[/tex]

Hence, the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex] is equal to [tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex].

Answer:

CROSS JOIN  (/^\s*symmetric\s*difference\s*$/)

Step-by-step explanation:

Remember, in SQL (Structured Query Language) operations, we can use the CROSS JOIN function to take data from one row of a table in the database and join it with each row of another table.

In other words, the result of FULL OUTER JOIN minus the INNER JOIN of the data set would require a CROSS JOIN operation which would the two different rows into one row.

Answer:

-6

Step-by-step explanation:

Let the first, second and third number be x, y and z respectively.

We are told that the second number is subtracted from the sum of the first number and 3 times the third number, the result is 2.

Thus;

(x + 3z) - y = 2 - - - (eq 1)

The third number plus 3 times the first number is -1.

Thus;

z + 3x = -1 - - - (eq 2)

The first number plus 3 times the second number plus the third number is -16.

Thus;

x + 3y + z = -16 - - - (eq 3)

From eq 2, we can rearrange to get;

z = -1 - 3x

Putting -1 - 3x for z in eq(1) and (eq 3),we have;

(x + 3(-1 - 3x)) - y = 2

x -3 - 9x - y = 2

-8x - y = 2 + 3

-8x - y = 5

y = -5 - 8x

Putting y = -5 - 8x and z = -1 - 3x into eq(3), we have;

x + 3(-5 - 8x) + (-1 - 3x) = -16

x - 15 - 24x - 1 - 3x = -16

-26x - 16 = -16

-26x = 16 + 16

x = 0

Since y = -5 - 8x, then y = -5 - 8(0)

y = - 5

Also, since z = -1 - 3x, then;

z = -1 - 3(0)

z = -1

The sum of the three numbers are;

x + y + z = 0 + (-5) + (-1) = -6

Answer:

Jenny cycles the grand distance of 29 and one third of a mile.

Step-by-step explanation:

I want to answer this using fractions and without multiplying by an awkward recurring decimal.

Cycling 11 miles in 45 minutes and continuing at the same speed means she will go 22 miles in 90 minutes

To scale up 90 mins to the required 120 mins (2 hours) multiply by 4/3.

22 x (4/3) = 88/3

Jenny will travel 88/3 miles in 2 hours.

Not happy with top heavy fractions?

Let's round up 88/3 to 90/3 by adding 2/3.

90/3 = 30 and to get back to the answer we just take away the two thirds we added when rounding up.

Jenny cycles the grand distance of 29 and one third of a mile.

I think that is the correct answer.

Answer:

The expected value is -$0.17

Since it gives a negative expected value, the game is not favorable and should not be played

Step-by-step explanation:

Here, we want to calculate the expected game value and decide if the game is worth playing

Probability of rolling a six is 1/6

Probability of rolling a 5 is 1/6

Probability of rolling a number less than 5 is 4/6 = 2/3

So the only way to win is rolling a six

The expected value is thus;

1/6(3) - 0(1/6) - 2/3(1)

= 1/2 - 2/3

= -$0.17

Since the game gives a negative expected value, it is not favorable and should not be played

In this exercise we want to use probability to calculate the value we will have in total after the event occurs, like this:

The value is -$0.17, with thw negative value, the game should not be played.

Let's organize the information given in the statement, in this way, we will have to:

With this combination of values, we find that the probability will be calculated as:

[tex]1/6(3) - 0(1/6) - 2/3(1)= 1/2 - 2/3\\= -$0.17[/tex]

Answer:

All lines with zero slope is a horizontal line.

y=mx+c slope is m. If m were zero, any x value substituted in would make y=(0)x+c, y=c.

Sub in the values 5=(0)(-3)+c, c would then be 5. So the equation would be y=5.

n(x) = -3x + 7

n(0) = -3(0) + 7

n(0) = 0 + 7

Grams

Step-by-step explanation:

Mass is the amount of matter present inside a solid. Kilograms and grams are the units to measure mass of an object.

For pencil, the unit to measure its mass is grams. As its mass is less, we can use smaller unit.

Hence, the correct option is (c) "grams"

Answer:

After 30 years 204 g of the substance will be left.

Option C is correct option.

Step-by-step explanation:

The function given is: [tex]A=600e^{-0.036t}[/tex]

where t is time in years.

We need to find how much of the  substance will be left in the sample after 30 years?

So, we have t= 30

Putting value of t and find value of A

[tex]A=600e^{-0.036t}\\A=600(\frac{1}{e^{0.036*30}})\\A=\frac{600}{e^{1.08}} \\A=\frac{600}{2.94467}\\A=203.75 \approx 204[/tex]

So, After 30 years 204 g of the substance will be left.

Answer:

The dimensions that will give the largest printed area of 132.1669 in^2 are

= Length x Width

= 15.20829 * 8.69045

Step-by-step explanation:

a) Data and Calculations:

Total poster area = 200 in^2

Side margins = 1 inch each

Top and bottom margins = 2 inches each

Let x = length of the full poster

then 200/x = width of the full poster

Therefore, the length of the printed area = x - 3.5

and the width of the printed area = (200/x)-2

Therefore, the Area of the Printed space = (x-3.5)((200/x)-2)

Solving for the Area (A) of the printed space, we have

A = (x-3.5)(-200/x2) + ((200/x)-2)

A = 700 -2x2

If the derivative is set to 0, we have:

0 = 700 -2x2

700 = 2x2

350 = x2

x = 18.70829  The original length

width = 10.69045

Therefore, the area of space available for printing is

15.20829  *  8.69045

= 132.1669 in^2

Answer:

x is 11

Step-by-step explanation:

We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1)

Substitute the numbers into the equation

y--4=3/4(x-3)

simplify

y+4=3/4(x-3)

do the distributive property

y+4=3/4x-9/4

subtract 4 from both sides

y=3/4x-25/4

this is the equation of the line.

Since it says that (x,2) is a point in the equation, we can substitute it into the equation

2=3/4x-25/4

add 25/4 to both sides

33/4=3/4x

multiply by 4/3

11=x

we can double check by plugging (11,2) into the equation of the line.

2=3/4(11)-25/4

2=33/4-25/4

2=2

it works! :)
