A plan flies 495 miles with the wind and 440 miles against the wind in the same length of time. If the speed of the wind is 10 mph, find the speed of the plain in still air

Answers

Answer 1

Let's assume the speed of the plane in still air is represented by 'p' (in mph).

When the plane is flying with the wind, its effective speed increases by the speed of the wind. So the speed of the plane with the wind is 'p + 10' (in mph).

When the plane is flying against the wind, its effective speed decreases by the speed of the wind. So the speed of the plane against the wind is 'p - 10' (in mph).

The time taken to travel a certain distance is given by the formula: Time = Distance / Speed.

Given that the length of time is the same for both situations, we can set up the following equation:

495 / (p + 10) = 440 / (p - 10)

We can cross-multiply to solve for 'p':

495(p - 10) = 440(p + 10)

495p - 4950 = 440p + 4400

495p - 440p = 4400 + 4950

55p = 9350

p = 9350 / 55

p ≈ 170

Therefore, the speed of the plane in still air is approximately 170 mph.

Answer:

We have to find the product of ,

(a+3)(a-2)

We will use the identity

(x+a)(x+b)=x² + (a+b)x+ab

So, (a+3)(a-2)=a²+(3-2)a+ (3)×(-2)

       = a²+1 × a -6

       = a²+a-6

Or , you can use the following method, to find the product.

a×(a-2)+3×(a-2)

=a² -2 a + 3 a-3×2

=a²+a-6

Answer: x=-4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

You would begin by dividing 6 from each side to get x alone so it'll look like this:

x = [tex]\frac{-24}{6}[/tex]

When you divide, you get -4 because a negative divided by a positive is still negative.

(x% of 60 is 3.006, 10% of 111 is y)

Answers

Answer:

x = 5.01%

y = 11.1

Step-by-step explanation:

[tex]\frac{percent}{base} = \frac{rate}{100}[/tex]

Model:

50% of 120 is 60

   Rate (%) = 50

   Base (of) = 120

   Percent (is, part) = 60

Thus, x in the first problem is the rate.

[tex]\frac{3.006}{60} =\frac{x}{100}[/tex]. Cross multiply, and we get:

x = 5.01

To check, multiply 5.01% × 60 = 3.006

For the second problem, multiply 10% with 111 to get the percent, which is 11.1
