The scale of a map is 4 cm: 15 km. if the distance on the map between two cities is 7 cm, what is the actual distance?

26.25 km

Step-by-step explanation:

Step up a portion.  Here, 4 cm is to 7 cm as 15km is to x km

4/7 = 15/x

Now solve for x by cross multiplying

4x = 105

  x = 105/4    (divide by 4 on both sides)

  x = 26.25 km    (simplify)

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
