The distance between the school and the airport on a map is 7.25 cm. The scale of the map is 1 cm : 12 m. What is the actual dis
Ann [662]
This problem can be solved via a simple ratio and proportion approach. The concept is, the ratio of the actual length to the model length is constant. The solution is as follows:

Actual/Model = 12 m/ 1 cm = x/7.25 cm
Solve for x,
x = 87 m

<em>So, the actual distance is 87 m.</em>

ohaa [14]

Answer:

Im pretty sure its 1,000 miles (dont forget the unit)

Step-by-step explanation:

Determine if this problem is a inverse variation or direct variation problem! This means that:

equation would be:

1=40

25=x

cross multiply*

x=25*40

x=1,000 miles apart! (dont forget the unit)

If this doesnt work then try this equation!

1=40

25=x

Multiply 1*40 and 25 *x

40=25x......    

40/25= 1.6

x=1.6! (Extra step)

Cheers!

John thinks that any two lines must have a point of intersection. Is he correct? If so how do you know. If not, produce a counte
bekas [8.4K]
This isn't necessarily true. When two lines have equivalent slopes, then they are parallel and will never intersect. 

y=1/2x + 12
y=1/2x + -2
These lines can't intersect because there are equal slopes.
