Answer:
I think it was Distributive
Step-by-step explanation:
Answer:
323.11 ft
Step-by-step explanation:
The ellipse has two different axes which are the major and the minor axes. The major axis is longer than the minor axis. Therefore,
Major axis length = 2*a = 380; a = 380/2 = 190 ft
Minor axis length = 2*b = 200; b = 200/2 = 100 ft
To calculate the distance between Walter and Barbara (2*c), we consider the lengths a, b, and c as a right-angle triangle. If we use the Pythagoras theorem, we have:
c^2 = a^2 - b^2 = 190^2 - 100^2 = 26100
c = sqrt(26100) = 161.55 ft
Therefore, the distance between Walter and Barbara = 2*161.55 = 323.11 ft
<h3><u>
The length is equal to 7.</u></h3><h3><u>
The width is equal to 3.</u></h3>
l = 1 + 2w
2l + 2w = 20
Since we have a value for l, we can plug it into the second equation.
2(1 + 2w) + 2w = 20
Distributive property.
2 + 4w + 2w = 20
Combine like terms.
2 + 6w = 20
Subtract 2 from both sides.
6w = 18
Divide both sides by 6.
w = 3
Now that we have a value of w, we can plug it into the original equation to find the exact value of l.
l = 1 + 2(3)
l = 7
