Answer: 16

Step-by-step explanation:

The cargo plane's speed is 576.7 km /hour.

Given, the cargo plane flew away 9 hours before an air force plane.

The air force plane is in the opposite direction.

speed of the air force plane is : 260 km/hr

time = 3 hours

distance for which plane's are apart = 5970 km

therefore, 9x + 3(260) = 5970

9x + 780 = 5970

9x = 5970 - 780

9x = 5190

x = 5190/9

x = 576.7 km

hence the speed of the cargo plane is 576.7 km.

Let x be a rational number and y be an irrational number. This is the correct choice.

Allow xy=a.

Suppose an is a rational being.

A can be stated as q p since it is rational, where p and q are both integers.

Let x = n m, where n and m are both integers.

Then, xy=a

n \smy \s​ \s = \sq \sp \s​ \s .

When we cross multiply, we obtain,

⇒y= qm \spn \s​ \s .

Pn and qm are currently integers.

Consequently, qm pn is a rational number.

Y, however, is illogical.

Consequently, our assumption is unfounded.

Therefore, an irrational number is always the result of adding a non-zero rational number to an irrational number.

Answer:

slope = - 3

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (5, - 6 )

m = [tex]\frac{-6-3}{5-2}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3

the coefficient "b" (the one with the linear term) is 12.

The general quadratic equation is:

a*x^2 + b*x + c = 0

I guess that you want to find the coefficient "b" on the given equation.

Then we can just expand the given quadratic equation:

(2x + 3)^2 = 0

(2x + 3)*(2x + 3) = 0

Expanding that we get:

4x^2 + 6x + 6x + 9 = 0

4x^2 + 12x + 9 = 0

So the coefficient "b" (the one with the linear term) is 12.

Answer:

n ≤ -1

Step-by-step explanation:

Inequality is a concept that refers to the unequal distribution of resources, opportunities, or status among individuals or groups. It can be measured in a number of ways, including income inequality, wealth inequality, and educational inequality.

For the Question:

Let's solve for 'n':

Given inequality:

[tex]\sf 9 + 8n \leq 1[/tex]

Subtract 9 from both sides:

[tex]\sf 9 + 8n -9 \leq 1 -9[/tex]

[tex]\sf 8n \leq -8[/tex]

Divide both sides by 8 (remember, since you're dividing by a negative number, the inequality sign flips):

[tex]\sf \dfrac{8n}{8} \leq \dfrac{-8}{8}[/tex]

n ≤ -1

So, the solution for 'n' that satisfies the inequality is n ≤ -1.

With the help of basic Arithematic Operations it is concluded that the store lose $7.25 by giving away the free tubes of paint.

A formula that depicts grouping objects into a bigger collection. The plus sign (+) serves as a symbol for it.

A calculation that symbolizes the process of determining a difference between two numbers or units. The negative sign serves as a symbol for it (-).

The cost of a paint tube = $7.25

The cost of 2 paint tubes = $7.25 + $7.25 = $14.50

Therefore, subtracting the cost of one free paint tube from the total cost of two paint tubes

$14.5 - $7.25 = $7.25

Hence, the store lose $7.25 per sale by giving away the free tubes.

Step-by-step explanation:

The probability that all the 4 cards are

1) hearts = 0.0026

2) face cards = 0.0018

3) even cards = 0.0179

In a standard deck of cards, we have:

Total number of cards= 52

1) The probability that all the cards are hearts.

In a standard deck of cards, we have:

the number of Hearts = 13

When a card is selected, the number of cards reduces by 1.

So, the probability that all the 4 cards are hearts is:

P1 = 13/52 × 12/51 × 11/50 × 10/49

P1 = 0.25 × 0.2353 × 0.22 × 0.2041

P1 = 0.0026

2) The probability that all the cards are face cards.

In a standard deck of cards, we have:

Face card = 12

When a card is selected, the number of cards reduces by 1.

So, the probability that all the 4 cards are face cards.

P2 = 12/52 × 11/51 × 10/50 × 9/49

P2 = 0.2308 × 0.2157 × 0.2 × 0.1837

P2 = 0.0018

3) The probability that all the cards are even.

In a standard deck of cards, we have:

Even cards = 20

When a card is selected, the number of cards reduces by 1.

So, the probability that all the 4 cards are even.is:

P3 = 20/52 × 19/51 × 18/50 × 17/49

P3 = 0.3846 × 0.3725 × 0.36 × 0.3469

P3 = 0.0179

Hence, the probability that all the 4 cards are even is 0.0179

Therefore, the probability that all the 4 cards are

1) hearts = 0.0026

2) face cards = 0.0018

3) even cards = 0.0179

Step-by-step explanation:

The algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.

Using the weights on each side of the scale, we can create an algebraic equation that describes it.

Assume each weigh on the scale represents each side of an algebraic equation.

On left side, we can express the weights as: 2y + 3

On the right side, we can express the weight as: 4y + 2

Thus, expressing the relationship of the weights, we would have:

2y + 3 = 4y + 2

Thus, the algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.

Yes, it is possible to draw a plane that contains a line and a point not in the line.

A plane is a flat two-dimensional surface that extends to infinity. Planes are points (0-dimensional), lines (1-dimensional), and the 2-dimensional analogue of 3-dimensional space. The plane has zero thickness, zero curvature, infinite width, and infinite length. It's actually difficult to imagine an airplane in real life. All the flat surfaces of a cube or cuboid, the flat surface of paper are all practical examples of geometric planes.

In any dimensional Euclidean space, a plane is uniquely defined by either: Use three non-collinear points. Use points and lines that are not on this line. Use two different lines that intersect.
