warehouse location (24,-32)
airport location (-24,32)
distance = sqrt((x2-x1)^2 +(y2-y1)^2)=
Sqrt(24--24)62 +(32--32)^2) =
sqrt(48^2 +64^2) =80
then distance from airport to the factory = -24 to 24 = 48
80+48 = 128 miles total
Step-by-step explanation:
Answer:
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Step-by-step explanation:
we know that
The area of the rectangle (movie screen) is equal to
where
L is the length
W is the width
we have
so
----> equation A
The screen is 20 feet longer than it is wide.
so
---> equation B
substitute equation B in equation A
solve for W
solve the quadratic equation by graphing
the solution is W=82 ft
see the attached figure
Find the value of L
therefore
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Zara has paper rectangles. Length and width of any rectangle is directly proportional.
<u>SOLUTION:
</u>
Given, Zara has paper rectangles of different sizes
Every rectangle is 5 cm longer than it is wide
We have to find that is there a proportional relationship between the length and width of these rectangles.
From the given information, length is 5 cm longer than width for any rectangle.
Then, length of rectangle = 5 + width of rectangle.
When we increase width of rectangle length also increases. From above equation.
Hence, length and width of any rectangle is directly proportional.
Greater=19
Smaller=3
Just use substitution
