x+3x+3x=21
7x=21
x=3
3, 9, 9=21
the answers are 3, 9, and 9
 
        
             
        
        
        
Answer:
5.3
Step-by-step explanation:
a² + b² =² c²               the Pythagorean theorem
RQ² + RS² = QS²            Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28                  28 is slightly > 25   and since  √25 =5
RS = 5.3                    actually 5.2915  to a few more significant digits
 
        
             
        
        
        
Answer:
24 times
Step-by-step explanation:
cone is used to fill cylinder
conevolume times x=cylindervolume
so
x=cylinderv/conev
cylinderv=hpir^2
conevolume=1/3hpir^2
cylinder:
v=hpir^2
r=10
h=20
v=20*pi*10^2=2000π
cone=1/3hπr²
r=5
h=10
v=1/3(10)π5²=250π/3
volume of cylinder ÷ volume of cone
= 2000π ÷ (250π÷3)
= 6000π ÷ 250π 
= 600÷25
= 24
