Which pair of slopes represent perpendicular lines?

1 answer:

3 0

The correct answer is C.

Perpendicular lines have opposite reciprocal slopes. This mean you will flip the original number upside down, and change its sign (negative to positive and vice versa). So, the opposite of -1/4 will be 4.

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per ho

Delicious77 [7]

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v= $9\frac{9}{10}km/h$

Speed of object, v= $9+0.9=9.9km/h$

Distance travel by object, s= $5\frac{1}{10}km$

Distance travel by object, s= $5+0.1=5.1km$

We have to find the time taken by object to travel 5 1/10 km.

We know that

$Time=\frac{Distance}{speed}$

Using the formula

Time taken by object to travel 5.1 km = $\frac{5.1}{9.9} hr$

Time taken by object to travel 5.1 km=0.52 hr
