The double number line shows that in 3 seconds an ostrich can run 63 meters . based on the ratio shown in the double number line how far can the ostrich run in 5 seconds

Ostrich can run in 5 second = 105 meter .

Step-by-step explanation:

Given  : The double number line shows that in 3 seconds an ostrich can run 63 meters .

To find : Based on the ratio shown in the double number line how far can the ostrich run in 5 seconds.

Solution : We have given

ostrich can run in 3 second = 63 meter .

Let ostrich can run in 5 second = x meter .

By the Ratio : 63 : 3 :: x : 5

On cross multiplication

63 * 5 = 3 * x

315 = 3 x

On dividing both sides by 3

x = 105 meter .

Therefore, ostrich can run in 5 second = 105 meter .

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
