Step-by-step explanation:

Answer:

a. 482

b. 9.0

Step-by-step explanation:

The speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Flight speed in air stream = Flight speed in still air + effect of air stream

If the flight is going opposit, then:

If the flight is going along with flight, then:

For this case, we're specified that:

Speed of flight along the stream is:

[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8} = 491.25 \: \rm mph[/tex]

Speed of flight against the stream is:

[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8.3} \approx 473.49 \: \rm mph[/tex]

Let the speed of air stream be y, and that of the flight in still air be x miles per hour, then we get:

Along air stream:

[tex]x + y =491.25\\[/tex] (in miles per hour)

and Against the stream:

[tex]x - y =473.49\\[/tex] (in miles per hour)

Adding both the equations side by side, we get:

[tex]2x + y - y = 491.25 + 473.49\\\\x = \dfrac{964.74}{2} =482.37 \: \rm mph[/tex]

Using this value, we get the value of y as:

[tex]x + y =491.25\\y = 491.25 - x = 491.25 - 482.37 = 8.88 \: \rm mph[/tex]

Rounding to the nearest whole numbers, we get:

x = 482 mph, and y = 9 mph

Thus, the speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Answer:

Slope=-1.8, X=-0.5, y=1.9

Equation is y^2-y^1=m(x^2-x^1).

Y-1.9=-1.8(X-(-0.5))

Y-1.9=-1.8x+0.90

Add 1.9 on both sides.

Y= -1.8x+1.

Answer:

5

Step-by-step explanation:

The given two triangles are similar , therefore ,

⇒ 5x /20 = 45/36

⇒ x/4 = 5/4

⇒ x = 5/4 × 4

⇒ x = 5

Hence the value of x is 5.

1028.5 is the mean

Answer:

481.75

Step-by-step explanation:

To find the mean add up all the numbers in the data set :

8 + 445 + 276 + 1198 = 1927

divide the numbers by how many numbers are in the data set :

1927 ÷ 4 = 481.75

Therefore, the mean in the data set 481.75

Answer:

The total cost of the new carpeting is $ 1,055.43.

Step-by-step explanation:

Since I decide that I want new carpeting in my bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long, and the price of the carpet and the underlying pad is $ 3.49 per square foot, and I decide to upgrade to the deluxe underlying pad that costs an additional $ 0.62 per square foot, and the fee for installation is a flat fee of $ 180, to determine what is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation, the following calculations must be performed:

1 inch = 0.08333 feet

6 inches = 0.08333 x 6 = 0.5

9 inches = 0.08333 x 9 = 0.75

12.5 x 15.75 = Bedroom area

196,875 square feet = Bedroom area

((196.875 x (3.49 + 0.62)) + 180) x 1.067 = Total cost

((196,875 x 4.11) + 180) x 1,067 = Total cost

(809.15625 + 180) x 1.067 = Total cost

989.15625 x 1.067 = Total cost

1,055,429 = Total cost

Therefore, the total cost of the new carpeting is $ 1,055.43.

Answer:

50-50 on both because there 3 even and 3 odd numbers

Answer:

50% chance of either or 1/2

Step-by-step explanation:

50% of either

Look a die has 12 sides

6 numbers are odd and the other 6 even

If you randomly roll a die you will have 6/12 chances of landing on a even number and a 6/12 chance of landing on a odd number

now 6/12 can be simplified to 1/2 which is 50%

Hope that helps!

Step-by-step explanation:

1. -10b+b=-9

It is like you are doing this:

-10+1=-9

5. 5k+7k=12k

5+7=12

3. 1+5v+v= 1+6v

Like: 5+1

2.-x-3x=-4x

Like:-3-1=4 (both are negative numbers and you just add the second one)

4.-7n-7-8+10n=3n-15

You are doing this with n:

10-7=3 and this with numbers:

-7-8=-15 (both negative again)

6.a-2+1+4a= 5a-1

Like this: 4+1=5 and -2+1=-1

7. 8(x+10)= 8*x+8*10= 8x +80

8. 8(1+6p)= 8*1+8*6p= 8+48p

9.-5(-7+7n)= 35-35n ( when you * negative and positive numbers you get negative result and when you * negative and negative numbers you get positive result)

10.-(9m+7)= -9m-7 ( when you have - before () every number changes its sign).

Sorry for messy writing... Hope this helps.
