Answer:

1.) 120 mph

2.) 30 mph

Step-by-step explanation:

Given that a  man flies a small airplane from Fargo to Bismarck, North Dakota- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.2 hours. What is the planes speed in still air, and how fast is the wind blowing?

Let the wind speed = w

and the plane speed = p

From the first sentence,

P - w = 180/ 2

P - w = 90 ....... ( 1 )

From the second statement,

P + w = 180/1.2

P+ w = 150 ...... ( 2 )

Solve equation 1 and 2 simultaneously

P + w = 150

P - w = 90

Add the two equations

2P = 240

P = 120 mph

Substitute p in equation 1

W = 150 - 120

W = 30

Therefore, the wind speed is 30 mph and the plane speed is 120 mph

Algebra I

Step-by-step explanation:

According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

Answer:

The surface area is 972 square cm

Step-by-step explanation:

Numeric Value of Functions

Given the function:

A = 252 + 4sh

Where A is the surface area of a square prism , s is edge length of the base  h is the height.

A square prism has a base with edges s=12 cm long and height of h=15 cm.

Substituting these values, we get:

A = 252 + 4(12)(15)

A = 252 + 720 = 972

A = 972

The surface area is 972 square cm

The surface area of the square prism is 1008 cm².

Surface area of a square prism:

where

s = edge side

h = height

Therefore,

s = 12 cm

h = 15 cm

surface area = 2 × 12² + 4 × 12 × 15

surface area = 2 × 144 + 48 × 15

surface area = 288 + 720

surface area = 1008

surface area = 1008 cm²

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, Today, the Ninth Amendment is used mainly to stop the government from expanding their power rather than just limiting their power.

The 9th amendment means that even if a right is not specifically mentioned in the Constitution, it still belongs to the people.

For example, in this case, the right to privacy. It's not specifically mentioned in the Constitution, but it is still a right that the government cannot take away.

Answer:

5⁰

Step-by-step explanation:

Angle on A STRAIGHT line sums up to 180⁰

angle PQR and angle RQS are both on a straight line therefore they sum up to 180⁰

4x+129+5x+6=180

then here you group like terms

4x+5x=150-129-6

9x=45

divide both sides by 9

9 dividing 45 is 5

Answer:

It’s (-9,-4)

Step-by-step explanation:

Edge

The focus of the graph of the function is located at (−9,−4).

Given that, the graph of y²+ 8y – 4x – 24 = 0 is a parabola. We need to find where is the focus located.

The vertex form of an equation is an alternate way of writing out the equation of a parabola. Normally, you'll see a quadratic equation written as ax²+bx+c, which, when graphed, will be a parabola.

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Right

Vertex: (−10, -4)

Focus: (-9, -4)

Axis of Symmetry: y=−4

Directrix: x=−11

Therefore, the focus of the graph of the function is located at (−9,−4).

y = - 1.5x - 15

Step-by-step explanation:

Step 1:

- 3x - 2y = 30         Equation

Step 2:

- 2y = 3x + 30        Add 3x on both sides

Step 3:

y = - 1.5x - 15      Divide 2 on both sides

Answer:

y = - 1.5x - 15

Hope This Helps :)

Answer:   y = - 1.5x - 15

Step-by-step explanation:

First, we will add 3x to both sides of the equation.

-2y = 3x + 30

Next, we will divide 2 on both sides of the equation.

y = -1.5x - 15

Answer -  y = -1.5x - 15

The value of x for the given geometry will be 20°.

The angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Given that AE is a bisector of ∠BAE and ∠EAC

so,

∠BAE = ∠EAC

x + 30 = 3x - 10

x = 20°

Hence 20° will be the answer to the given question.

Answer:

The car will travel between 250 and 300 miles with a consumption of between 10 and 12 gallons of gasoline.

Step-by-step explanation:

If a car travels 25 miles on a gallon of gasoline, when using between 10 and 12 gallons of gasoline, the miles it will travel are derived from the following calculation:

1 = 25

10 = X

((25 x 10) / 1) = X

250 = X

So if you use 10 gallons of gasoline, the car will travel about 250 miles. Now if you use 12 gallons, it will go about 300 miles.

Therefore, the car will travel between 250 and 300 miles with a consumption of between 10 and 12 gallons of gasoline.
