Answer:
The Answer is: 6 inches by 5 inches.
Step-by-step explanation:
Given: A structure that is 30 ft by 25 ft.
Scale: 3 in to 15 ft.
Or - Scale: 1 in to 5 ft.
Divide the sides by 5 to get how many 1" sections:
30 ft / 5 = 6 inches
25 ft / 5 = 5 inches
The sides of the drawing are 6 inches by 5 inches. This represents the 30 ft by 25 ft rectangle.
Hope this helps! Have an Awesome Day!! :-)
Answer:
x^2/100 + y^2/256 = 1
Step-by-step explanation:
The standard form of an ellipse is (x-h)^2/a^2+(y-k)^2/b^2=1
a is the horizontal radius
b is the vertical radius
h is the shift to the right
k is the shift upward
h and k will be shifts left and downward respectively if they are negative. Since the question doesn't mention any shifting we can just let them be 0 so everything is easier. The problem states the vertical axis is 16 and the horizontal axis is 10 so that means a = 10 and b = 16. Now we just plug in.
(x-h)^2/a^2+(y-k)^2/b^2=1
a = 10
b = 16
h = 0
k = 0
x^2/10^2+y^2/16^2=1
x^2/100 + y^2/256 = 1
