Answer:
15 kg
Step-by-step explanation:
Radius of a solid sphere : mass of a solid sphere
3 cm : 9 kg
Find the mass of a sphere of the same material of radius 5 cm
Radius of a solid sphere : mass of a solid sphere
5 cm : x kg
Equate both ratios to find x
3 cm : 9 kg = 5 cm : x kg
3/9 = 5/x
3 * x = 9 * 5
3x = 45
x = 45/3
x = 15 kg
The mass of a sphere of the same material of radius 5 cm is 15 kg
I'm going to assume you mean 3 to the power negative 5.
3^-5
Use rule [ x^-y = 1/x^y ]
3^-5 = 1/3^5 = 1/243
Best of Luck!
Answer:
2
Step-by-step explanation:
2/3÷1/3
Changing the divide sign into multiply will invert the term after it
So we get
(2/3)*3
(2*3)/3
We get
2
