Mathematics
1 answer:
Ainat [17]2 years ago
7 0

Answer:

Step-by-step explanation:

This is a Pythagorean Theorem Question

c^2 = a^2 + b^2

c= sqrt(5)

a = x

b = x            This is an isosceles right triangle. The vertical side and the horizontal side are equal.

x^2 + x^2  =  sqrt(5)^2

2x^2 = 5                           Divide both sides by 2

x^2 = 5/2                          Take the sqrt of both sides.

√x^2 = √5 / √2                Multiply right side by √2 on both top and bottom

x = √5*√2 / √2*√2

x = √10 /2

The local train heading for Westford at 60km/h and the express train heading for Eastford at 80 km/h pass each other at Centervi
Wewaii [24]

Answer:

The maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.

Step-by-step explanation:

Local train stats:

Rate = 60 km/h

Distance = x km

Time = x/60 hours

Express train stats:

Rate = 80 km/h

Distance = (195-x) km

Time = (195-x)/80 hours

Now we will equate both the times.

x/60 =(195-x)/80

x/3= (195-x)/4

4x= 585-3x

7x= 585

x = 83.57 km

195-x=195-83.57= 111.43 km

Hence, the maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.

Solve 5x÷6=20.<br><br> The solution is x=
puteri [66]
We want to get x by itself
First we will multiply both sides by 6 to cancel out the 6 on the left
5x = 120
We then divide by 5 on both sides to get x by itself
x = 24
