if an airplane travels 660 mph how long will it take an airplane to travel to a distance of 2970 miles?
vazorg [7]

Answer:

4 hours and 30 minutes.

Step-by-step explanation:

660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours

There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.

So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.

Hope this helps!

Can someone please do this for me?
san4es73 [151]

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

\frac{3}{2}x = 174

x = 116

<em>Plug it back in:</em>

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

<em>To check:</em>

116 + 64 = 180 ✓

Find the slope of a line parallel to the line that crosses ( 3 , − 2 ) and the y -intercept is ( 0 , − 3 ) . I finally figured o
mamaluj [8]

Answer:

y = 1/3x - 3

Step-by-step explanation:

We can find the equation of the line, by finding the slope and combine with our y-intercept (-3).

We need to use the slope formula to find the slope.

Thus, we have (-3 - (-2)) / 0 - 3 = -1/-3 = 1/3

So our equation is y = -1/3x - 3
