Answer:

The answer is 60/100 = 45/x !

Step-by-step explanation:

60 percent is the part; 100 percent is the whole. 45 is the part and x, the unknown, is the whole. These numbers make a proportion: 60 is to 100 as 45 is to x.

A service station will be built on the highway, and a road will connect it with cray. How long will the new road be?
maxonik [38]

Answer:

46.2 mi is the right answer.

Step-by-step explanation:

In this question we will follow the property of congruence of two triangles.

Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.

The distance between Alba and Blare = 130 mi

The distance between Alba and Cray = 120 mi

As we know in the congruent triangles all sides are in the same ratio.

Now we apply the property of the theorem

\frac{Distance(Alba-Cray)}{Distance(Alba-Blare)}= \frac{Distance(Cray-Service station)}{Distance(Cray-Blare)}

\frac{120}{130}=\frac{x}{50}

x=50\frac{120}{130}

x = 46.2 mi
