Step-by-step explanation:
Answer:
5:7
Step-by-step explanation:
Let the radius of first hemisphere be 'r' units
Let the radius of second hemisphere be 'R' units
2 x \piπ x r^2 / 2 x \piπ x R^2 = 25 / 49
r^2 / R^2 = 25 / 49
r / R = 5 / 7
the ratio of radii is 5:7.

Answer:
G-7×17=119
Step-by-step explanation:
A prime number is a number which has only two factors, 1 and itself.
A composite number on the other hand is any number that has more than two factors.
In the options
In F-5×15=75, 15 can still be decomposed into 5X3
In H-9×19=171, 9 can still be decomposed into 3X3
In J-11×21=231, 21 can still be written as 7X3.
So option G is the only equation which could show Brodricks work.
