You find out by multiplying the denominator: 20 * 5 = 100

Then, you do the same to the numerator which is: 16 * 5 = x

So, x = 80%

Hope this helps! :D

If Rahul walks 9km in a week and Vansh walks 900 m daily, which of these is true about the distances they cover in a week?

Answer: Rahul walks 2.7 km more than Vansh.

Step-by-step explanation:

The options include:

a. Vansh walks 7.2 km more than Rahul.

b. Vansh walks 2 km more than Rahul.

c. Rahul and Vansh both cover the same distance.

d. Rahul walks 2.7 km more than Vansh.

Distance covered by Rahul weekly = 9km

Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km

From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.

Note: 1000 meters = 1 kilometers

Step-by-step explanation:

The arc length is very different from the arc measure, so make sure you know the difference. Arc length is measures in feet or inches or meters or cm, etc., while arc measure is measured in degrees, like angles. The formula we need for arc length includes the circumference of a circle formula, since the arc is part of the circumference. The formula includes the angle that cuts off that arc:

$AL=\frac{\theta}{360}*2\pi r$ where theta is the central angle that cuts off the arc we are finding the length of. That angle is 100 degrees; the radius if 12. Filling in the formula with those values and using 3.14 for pi:
