Answer: There are 192 horses in the ranch
Step-by-step explanation:
The combined number of cattle and horses = 960.
Ratio of cattle to horses =12 :3
Total ratio =12+3=15
Number of horses on the ranch = ratio of horse / Total ratio x total number of horses and cattle
3/15 x 960 = 192
Therefore there are 192 horses in the ranch

Step-by-step explanation:
Answer:
So the correct option is First one
i.e 
Step-by-step explanation:
Given:
Area of Shaded part = 9 π square feet
To Find :
Area of Circle = ?
Solution:
90 degree center angle is equivalent to an area of 9 Π square feet
So, 360 degree center is equivalent to area A which is the area of the complete circle.
So the Ratio will be
Setting the given statements in proportion:

On solving we get the required

So the correct option is First one
i.e 
Alternate Method:
Shaded part is of 90°
Area of Shaded part = 9 π square feet
And Full Circle is of 360° that is 4 sector of 90°



So the correct option is First one
i.e 
On solving this we get
