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
Answer: 11/3 as a mixed number is 3 2/3
<u><em>Answer: x<-6 *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract 5 both sides of an equation.
5-2x-5>17-5
simplify.
-2x>12
multiply by -1 both sides of an equation.
(-2x)(-1)<12(-1)
simplify.
2x<-12
divide by 2 both sides of an equation.
2x/2<-12/2
-12/2=-6
12/2=6
6*2=12
12/6=2
x<-6
Hope this helps!
Thanks!
Have a great day!
