Answer:

It passes through the point (3,4). Given that the center of the circle is the point (0,0). We know that the equation of the circle is given by : (x-a)^2 + (y-b)^2 = r^2 where (a,b) is the center and r is the radius.

Austin takes 1 minute and 45 seconds to run three-quarters of a circular track. His rate of motion is /
castortr0y [4]
Length of circular track is:

L = 2*r*pi

He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi

To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds

v = L'/t = 3*r*pi/2*105

v = r* pi/70

If we take that r = 1

Nostrana [21]

Answer:

5/24

Step-by-step explanation:

The question in English is

A tank is filled with water daily to give water to the animals on a farm. As required, 3/8 of the water was taken from the tank to give to the horses and 1/3 of what was left in the tank was given to the pigs. The remainder of the tank was distributed in two equal amounts to give water to the birds and pets. What is the fraction of the water that pets receive to drink?

1) 3/8 of the water was taken from the tank to give to the horses

At this point in the tank there are 1-3/8=5/8 of the water of the tank

2) 1/3 of what was left in the tank was given to the pigs

At this point in the tank there are

(1-1/3)*5/8

(2/3)(5/8)=10/24 of the water of the tank

3) The remainder of the tank was distributed in two equal amounts to give water to the birds and pets

The remainder is equal to 10/24

divided by 2

(10/24)/2=10/48

4) The fraction of the water that pets receive to drink is 10/48

simplify

10/48=5/24
