Answer:
The center of circle is 
Step-by-step explanation:
We need to find the center of the circle of the equation 
Since, the general equation of circle is 
Where (h,k) is center of circle and r is radius.
Re-write the circle equation is as,
Compare with
so, 
Hence, the center of circle is
Answer:
PR = 24.5
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, that is
= 
( cross- multiply )
18PR = 28 × 15.75 = 441 ( divide both sides by 18 )
PR = 24. 5
Answer: 6 inches
Explanation:
12 = 1(2)h
12 = 2h
12 ÷ 2 = 2h ÷ 2 (isolating the H term)
6 = h
3x - 246 = 76 - 11x
-3x. subtract. -3x
-246 = 76-14x. subtract 76 both sides
-76= -76-14x
-322=-14x
divide both sides by -14
x= 23
Feet are smaller than yards, so the numerical value would be higher.
