Assume that the dimensions of the room in the plan are a (width ) by b (length),
such that a*b=30.
Since the scale is 1:100, a represents 100a, and b represents 100b.
So the actual dimensions are 100a by 100b.
The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)
Answer: 300,000 (square units)
Answer:

Step-by-step explanation:
Given two points are (-1,7) and (7,7).
We are told to find a point which is in between them at a ratio of 6:5.
Formula for calculating a point at distance of ratio m:n is given by

where
are the inital and final points.

also m:n=6:5 ,
by substituting all the values we get,


Answer:
y=2/7x-4
Step-by-step explanation:
Write in Slope intercept form
y=mx+b
m = slope
b = y intercept
x = x intercept
y = (0,-4)
So,
y = 2/7x+(-4) substitute
y = 2/7x-4
Answer:
9
Step-by-step explanation:
x+1/3x=12
(3x+1x)/3=12
4x/3=12
4x=12×3
4x=36
x=36/4
x=9
