Gennadij [26K]3 years ago

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

Serggg [28]

Answer:

12.60

Step-by-step explanation:

Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.
