The speed of the plane is 900 km/h, and the speed of the wind is 100 km/h.

Let's denote the speed of the plane as P and the speed of the wind as W.

When the airplane is flying with the wind, the effective speed of the plane is increased by the speed of the wind. Conversely, when the airplane is flying against the wind, the effective speed of the plane is decreased by the speed of the wind.

We can set up two equations based on the given information:

With the wind:

The speed of the plane with the wind is P + W, and the time taken to cover the 8000 km distance is 8 hours. Therefore, we have the equation:

(P + W) * 8 = 8000

Against the wind:

The speed of the plane against the wind is P - W, and the time taken to cover the same 8000 km distance is 10 hours. Therefore, we have the equation:

(P - W) * 10 = 8000

We can solve this system of equations to find the values of P (speed of the plane) and W (speed of the wind).

Let's start by simplifying the equations:

(P + W) * 8 = 8000

8P + 8W = 8000

(P - W) * 10 = 8000

10P - 10W = 8000

Now, we can solve these equations simultaneously. One way to do this is by using the method of elimination:

Multiply the first equation by 10 and the second equation by 8 to eliminate W:

80P + 80W = 80000

80P - 80W = 64000

Add these two equations together:

160P = 144000

Divide both sides by 160:

P = 900

Now, substitute the value of P back into either of the original equations (let's use the first equation):

(900 + W) * 8 = 8000

7200 + 8W = 8000

8W = 8000 - 7200

8W = 800

W = 100

Therefore, the speed of the plane is 900 km/h, and the speed of the wind is 100 km/h.

The value of x is ,

When a variable's value is put into an equation, it produces a true declaration, which is known as the solution. The action of determining an equation's solution is referred to as solving the problem. Determining the equation's solution helps to determine the value of the variable that renders the equation true.

The set of values used to substitute the unknowns in an equation to make it true is known as the solution. Two fundamental algebraic laws, the additive property and the multiplicative property, are used to find the solutions to equations with a single unknown raised to a single power.

Answer:

y = -4x-34

Step-by-step explanation:

From the line to which the line is parallel, we can get the slope

The general form of a linear model is;

y = mx + b

where m

is the slope and b is the y-intercept

From the question, using the given line,

we have the slope of that line as -4

Now, we want to write the equation of a line that passes through (-7,-6) and has a slope of -4

we can use the point-slope form

for this

That would be;

y-y1 = m(x-x1)

y + 6 = -4(x+ 7)

y + 6 = -4x -28

y = -4x -28-6

y = -4x - 34

The fewest possible number of green marbles in the bag is 5.

As per the stated question.

Since there is a 35% possibility of obtaining a red, the same percentage must apply to getting a white.

35+35=70%

You have a 100% probability of selecting a marble,

70+30=100

The probability that you will select a blue or green stone must thus be 30%.

And if there are B blue marbles, then there will be 5 green marbles.

B+5B=30%

6B=30%

Blue=5%

Green = 30-5=25%

Thus, the ratio becomes.

Red: White: Green : blue

35  : 35     :       25:    5

Dive each by 5.

Answer:

43.75

Step-by-step explanation:

lol look it up bruh

The 1400 divided by 32 is equal to 43 with a remainder of 16.

To calculate 1400 divided by 32, we perform the division operation step by step.

Step 1: Divide the first two digits of 1400 (14) by 32:

14 ÷ 32 = 0 with a remainder of 14

Step 2: Bring down the next digit of 1400 (0) and combine it with the remainder from Step 1 (14) to form 140:

140 ÷ 32 = 4 with a remainder of 12

Step 3: Bring down the next digit of 1400 (0) and combine it with the remainder from Step 2 (12) to form 120:

120 ÷ 32 = 3 with a remainder of 24

Step 4: Bring down the last digit of 1400 (0) and combine it with the remainder from Step 3 (24) to form 240:

240 ÷ 32 = 7 with a remainder of 16

Step 5: There are no more digits left to bring down, so the final result is 7 with a remainder of 16.

Therefore, 1400 divided by 32 is equal to 43 with a remainder of 16.

Answer:

∠ WXY = 20°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ XYZ is an exterior angle of the triangle, thus

10x - 5 = 3x + 17 + 3x + 2

10x - 5 = 6x + 19 ( subtract 6x from both sides )

4x - 5 = 19 ( add 5 to both sides )

4x = 24 ( divide both sides by 4 )

x = 6

Thus

∠ WXY = 3x + 2 = 3(6) + 2 = 18 + 2 = 20°

Complete Question:

Luke, Kira, and Ali each served 2/3 of their own cake. Each cake was the same size, but Luke served 4 slices, Kira served 6 slices, and Ali served 8 slices. How is this possible? Enter your answers in the boxes to complete the solution.

A. Luke cut his cake into how many slices?

B. Kira cut her cake into how many slices?

C. Ali cut her cake into how many slices.

Answer:

A. 6 slices.

B. 9 slices.

C. 12 slices.

Step-by-step explanation:

Given the following data;

Number served by Luke = 4 slices

Number served by Kira = 6 slices

Number served by Ali = 8 slices

We would solve for the number of slices each of them divided their cakes into.

For Luke, serving 2/3;

\( \frac {4}{\frac{2}{3}} = \frac {4 * 3}{2} \)

\( \frac {4}{\frac{2}{3}} = \frac {12}{2} \)

\( \frac {4}{\frac{2}{3}} = 6 \; slices \)

For Kira, serving 2/3;

\( \frac {6}{\frac{2}{3}} = \frac {6 * 3}{2} \)

\( \frac {6}{\frac{2}{3}} = \frac {18}{2} \)

\( \frac {6}{\frac{2}{3}} = 9 \; slices \)

For Ali, serving 2/3;

\( \frac {8}{\frac{2}{3}} = \frac {8 * 3}{2} \)

\( \frac {8}{\frac{2}{3}} = \frac {24}{2} \)

\( \frac {8}{\frac{2}{3}} = 12 \; slices \)

Therefore, it is possible because;

A. Luke cut his cake into 6 slices.

B. Kira cut her cake into 9 slices.

C. Ali cut her cake into 12 slices.

The area between the curve f(x)=√x and g(x) = x³ is  -5/12 square units.

The area between the curve f(x)=√x and g(x) = x³ is given by the definite integral as shown below:∫(0 to 1) [g(x) - f(x)] dx

To evaluate the definite integral, we need to calculate the indefinite integral of g(x) and f(x) respectively as follows:

Indefinite integral of g(x) = ∫x³ dx = (x⁴/4) + C

Indefinite integral of f(x) = ∫√x dx = (2/3)x^(3/2) + C

Where C is the constant of integration.

We can substitute the limits of integration in the expression of the definite integral to get the following result:

Area between the curves = ∫(0 to 1) [g(x) - f(x)] dx

= ∫(0 to 1) [x³ - √x] dx

= [(x⁴/4) - (2/3)x^(3/2)]

evaluated from 0 to 1= [(1/4) - (2/3)] - [(0/4) - (0/3)]= [(-5/12)] square units

Therefore, the area between the curve f(x)=√x and g(x) = x³ is equal to -5/12 square units.

To get r, you need to isolate the variable

Subtract the 4.4 from both sides

-7.8 - 4.4 = 4.4 + 2r - 4.4

The y-coordinate for the solution to the system of equations is -3.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.

Given system of equations are,

6x + 11y = -3

4x + y = 17

To solve these equations, we must first remove x or y terms.

To do this we must make the removing term's coefficients the same.

In this case, let's remove y.

We are multiplying the second equation by 11. Then,

6x + 11y = -3

44x + 11y = 187

Now we will subtract the second equation from the first.

- 38x  = -190

x = 5

Now to find y, substitute x in any one of the equations.

6 * 5 + 11y = -3

11y = -33

y = -3

Hence the y-coordinate for the solution to the system of equations is -3.

The domain restrictions of the expression q²−7q−8/q²+3q−4 are q ≠ -4 and q ≠ 1. (option c)

The denominator of the expression is q²+3q−4. To determine the values that would make the denominator equal to zero, we can set it equal to zero and solve for q:

q² + 3q - 4 = 0

Now, we can factorize the quadratic equation:

(q + 4)(q - 1) = 0

To find the values of q, we set each factor equal to zero and solve for q:

q + 4 = 0 or q - 1 = 0

Solving these equations, we get:

q = -4 or q = 1

So, the values of q that would make the denominator equal to zero are q = -4 and q = 1. These are the values we need to exclude from the domain of the expression to avoid division by zero.

Therefore, the correct answer is option c) q ≠ 1 and q ≠ -4.

To the nearest whole number, the probability of rolling a 2 and a 4 is 2.8%.

A 2 rolling up on the first throw has a 1/6 chance of happening. Given that a 2 was rolled on the first throw, the likelihood of rolling a 4 on the second throw is equally 1/6. We will have to multiply the probabilities to get the probability of both the events happening,
