If the area of the rectangle is 30 sq meters, that means length x width = 30.

So how do we find length and width? Well, they give us the perimeter of 34 which is length×2 + width×2. So if we find 2 factors of 30 that add up to 1/2 of 34, we'll find our length and width.

1/2 of 34 is 17

Let's look at the factors of 30...

1×30
2×15
3×10
5×6

We need the factors that add to 17... 15 + 2 = 17

So we know our rectangle has dimensions

Length 15 meters
Width 2 meters

Let's check the answer...
a = length × width
30 = 15×2
30 = 30 check!

perimeter = 2×L + 2×W
34 = 2×15 + 2×2
34 = 30 + 4
34 = 34. Check!!

A plane flies 720 miles with the wind in 3 hours. The return trip against the wind takes 4 hours. What is the speed of the wind
Mandarinka [93]
Let p and w represent the speed of the plane and the speed of the wind, respectively.
.. speed = distance/time
.. p +w = 720/3 = 240
.. p -w = 720/4 = 180

Add the two equations to eliminate w.
.. 2p = 420
.. p = 210
.. w = p -180 = 30

The speed of the wind is 30 mph.
The speed of the plane in still air is 210 mph.

Can I have help with the question

Answer:

Midpoint = (3.5, 4.5)

Perpendicular bisector = y =  \frac{7}{9} x + \frac{16}{9}

Step-by-step explanation:

[] We can solve this using the midpoint formula:

-> See attached

[] Plug-in our coordinates and solve:

(\frac{7+0}{2} ,\frac{0+9}{2} )=(\frac{7}{2} ,\frac{9}{2} )=(3.5,4.5 )

[] Now we will find the slope to solve for the perpendicular bisector.

-> We will use slope-intercept form, see attached

\frac{9-0}{0-7}=\frac{9}{-7}

-> The slopes of two perpendicular lines are negative reciprocals of each other, so \frac{7}{9} will be the slope of or perpendicular bisector

-> Now we can solve for the equation by using y – y1 = m ( x – x1), were y1 and x1 are the coordinates of our midpoint

y - 4.5 = \frac{7}{9} (x-3.5)

y - 4.5 = \frac{7}{9} x-\frac{49}{18}

y = \frac{7}{9} x-\frac{49}{18} + 4.5

y =  \frac{7}{9} x + \frac{16}{9}

Have a nice day!
