Value of p for given inequality of three fourths times p plus 8 is greater than or equal to 3 is p is greater than or equal to negative twenty over three.

As given in the question,

Given inequality:

Three fourths times p plus 8 is greater than or equal to 3 is written as

(3/4)p + 8 ≥ 3

Simplify inequality to get the value of p

  (3p + 32)/4 ≥ 3

⇒ 3p + 32 ≥ 12

⇒ 3p ≥ 12 -32

⇒ 3p ≥ -20

⇒ p ≥ -20 /3

Therefore, value of p for given inequality of three fourths times p plus 8 is greater than or equal to 3 is p is greater than or equal to negative twenty over three.

From the figure of triangles, scale factor of A and B, the value of x = 3

According to the question, given that

when two triangle are same, then we easily get missing value x

From the figure, two triangle are similar in it thus,

[tex]\frac{x}{1}[/tex] = [tex]\frac{9}{3}[/tex]       {property of triangles which are similar}

x = [tex]\frac{9}{3}[/tex] .

x = 3

Therefore, we get scale factor of triangle A and B, the missing value of missing x = 3.

Scale factor is the proportion of an original object's scale to a new one that is a representation of it but is a different size (bigger or smaller).

For example, if we have a rectangle of sides 4 cm and 6 cm, we can enlarge it by multiplying each side by a number, say 4. The new figure we get will be similar to the original figure, but all its dimensions will be twice that of the original rectangle.

In order to find what factors could represent the length and the width, we need to factor the polynomial that represents the area.

To do so, first let's find the zeros a1 and a2, then we can factor as follows:

Where k is the coefficient of the quadratic term (so k = 12).

Using the quadratic formula, we have:

Then, we have:

Therefore the factors are 2a-1 and 6a+5.

Using proportions, the amounts are given as follows:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.

One example of application is for percentage problems, as the equivalent amount can be found multiplying the equivalent decimal by the total amount.

The amount of Federal Income Tax Withholding each month is given by:

0.2 x 3500 = $700.

The amount of State Income Tax Withholding each month is given by:

0.12 x 3500 = $420.

The amount of Social Security Tax Withholding each month is given by:

0.0825 x 3500 = $288.75.

The amount contributed to the 401k each month is:

0.04 x 3500 = $140.

The take-home pay for the month is the $3,5500 subtracted by all the with holdings, hence:

3500 - (700 + 420 + 288.75 + 140) = $1,951.25.

A year has 12 months, hence the take-home pay for the year is given by:

Step-by-step explanation: find the reciprocal of g to the -7th power which would be 1 over g to the 7th power

g(x) is a dilation of scale factor 1/2 of f(x), and the rule is:

g(x) = 2x + 3

Here we have the function f(x) = 4x + 6 and the function g(x) that is defined as:

g(x) = (1/2)*f(x)

So g(x) is a vertical dilation of scale factor k = 1/2 of f(x).

Replacing f(x) in there we get:

g(x) = (1/2)*(4x + 6) = (4/2)*x + 6/2 = 2x + 3

The rule for g is:

g(x) = 2x + 3

The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.

This is a question of percentages.

Given that:-

Price of bouquet of flowers = $ 55

Sales tax % = 6.5 %

Tip % = 15 %

Delivery fee= $10

We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.

Sales tax = (6.5/100)*55 = $3.575

$55 + $3.575 = $58.575

Tip = (15/100)*58.575 = $ 8.78625

Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4

Hence,

Change received by Grant = 100 - 67.4 = $ 32.6

Answer:

[tex]y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

Step-by-step explanation:

The genera slope-intercept equation of a line is

y = mx + 8 where m is the slope and b the y-interecept

A perpendicular line will have a slope = -1/m ie the negative of reciprocal of the first line such that m x (-1/m ) = -1

The equation of the tangent line is

3x + 2y = 28.

1. Convert to slope-intercept form:

So slope = -3/2

Reciprocal of -3/2 = -2/3
Negative of reciprocal = +2/3

Slope of a perpendicular line should be -1/3 and the resultant equation of the line(the support arm) should be:

y = (2/3)x + b

To calculate b for the complete line equation plug in the point B(4, 8) and solve for B

y = 8 when x = 4

=> 8 = (2/3)(4) + b

Switch sides: (does not change any signs)
8/3 + b = 8

Subtract  8/3 on both sides
b =  8 - 8/3

b = 24/3 -  8/3

b = 16/3

So equation of the support arm is

[tex]\boxed{y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

The total volume taken by the coins is 88.47 cubic inches, so the correct option is D.

The coins are cylinders with a radius of 1.4 inches and a height of 0.0625 inches.

Remember that the volume of a cylinder is given by:

volume = (height)*pi*(radius)^2

Where pi = 3.14

Then here the volume of each coin is:

V = (0.0625 in)*3.14*(1.4 in)^2 = 0.384 in³

And there are 230 coins, so the total volume is:

V = 230*0.384 in³ = 88.47 in³

So the correct option is D.

Answer: D: 88.47 in³​

Step-by-step explanation: So what you want to do is first find the individual volume of the coins. Use the volume formula: V = πr^2h

Take 1.4 and times it by itself

1.4 x 1.4 = 1.96

Now multiply 1.96 by 0.0625

1.96 x 0.0625 = 0.1225

And times 0.1225 by pi, or in this case, 3.14

0.1225 x 3.14 = 0.38465

Now you have found the individual volume of each coin. You are trying to find how much space all of the coins take up together. The question says that there is 230 coins in total. So times 0.38465 by 230 to find how much space all the coins take up.

0.38465 x 230 = 88.4695 in³
Now round it to the nearest hundredth: 88.47 in³

That is your answer.

The given quadrilateral RSTV is a kite.

The following characteristics apply to quadrilaterals, which are polygons.

To classify the quadrilateral calculate the length of its sides using the distance formula given as follows:

[tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

In the given quadrilateral RSTV,

RS = [tex]\sqrt{(2 - (-5))^{2} + (6 - 7)^{2} }[/tex] = [tex]\sqrt{50 }[/tex]

RV = [tex]\sqrt{(-4 - (-5))^{2} + (0- 7)^{2} }[/tex] = [tex]\sqrt{50}[/tex]

ST = [tex]\sqrt{(5 - 2)^{2} + (-3- 6)^{2} } = \sqrt{90}[/tex]

VT = [tex]\sqrt{(-3 - 0)^{2} + (5- (-4))^{2} } = \sqrt{90}[/tex]

The equation to determine the number of players the team can bring is $842.50 + $21.50y = $1,186.50

The team can bring 16 players to the tournament.

To go to a tournament, softball team members raised $1186.50 and rented a bus for $842.50, and the cost of meals of each player is $21.50.

Let y represent the number of players.

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50y = $1,186.50

Subtracting $842.50 from each side.

$21.50y =  $1,186.50 - $842.50

$21.50y =  $344

Divide both side of the equation by $21.50.

x = $344 / $21.50

x = 16 players

Using a system of equations, a possible set of values for a, b and c such that it results in an integer number is given by:

a = 6, b = 3, c = 2.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.

In the context of this problem, the variables are the given ones of:

a, b and c.

An integer number is a number that has no decimal part, hence the easiest way to solve this is making the sum of 1.

Attributing a = 6, we have that:

[tex]\frac{1}{6} + \frac{1}{b} + \frac{1}{c} = 1[/tex]

[tex]\frac{1}{b} + \frac{1}{c} = \frac{5}{6}[/tex]

This is possible with these two fractions:

[tex]\frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6}[/tex]
