We are given the ratio of 1/2 inch: 18 miles
Multiply both sides of the ratio by 2. I'm doing this so that the "1/2" turns into "1"
So we go from this ratio
1/2 inch: 18 miles
to this ratio
1 inch: 36 miles
which means that every inch on paper represents 36 miles in real life
----------------------------------------------------------------
The question is now: if two towns are 2.5 inches apart on paper, then how far are they in real life? (note: 2.5 is the decimal form of 2 and a half)
To find out, multiply both sides by 2.5
1 inch: 36 miles
2.5*(1 inch): 2.5*(36 miles)
2.5 inches: 90 miles
--------------------------------------------------------------------------
Answer: The two towns are 90 miles apart in real life
As we know that volume is three dimensional so we will multiply width, length and depth
Now as we have to find the depth of the pool so
Volume= length*width*depth
depth=Volume/(length*width)
d=2500/(40*22)
d= 2500/880
depth=2.841ft
The slope intercept form is y=mx+b notice y's coefficient is 1
7y+5x=-15
subtracting 5x
7y=-5x-15
dividing by 7
y=(-5/7)x-(15/7)
To a higher number the six changes value in this number above
