Answer:

Step-by-step explanation:
We solve the inequality similarly to how we would solve an equalitu.




Multiplying everything by -1

Simplifying by 2


8 divided by 3 is 2 with rest two. So as a improper fraction, the answer is:

 
        
             
        
        
        
Answer:
it is C. Q3- Q1 tell me if it was right or not
OR if it is for a listing order it would be this List in ascending order:-
32 39 45 48 50 57 65 68 70
Q1 = (39+45)/2 = 42
Q2 = 50
Q3 = (65+68)/2 = 66.5
Correct option is the first one if there are choices 
 
        
             
        
        
        
Answer:
(-5,6)
Step-by-step explanation:
G(-5,4)=(x1,y1)
H(-5,8)=(x2, y2)
midpoint=?
now,
(x,y)= x1+x2/2     y1+y2/2
          -5-5/2        4+8/2
            -10/2          12/2
              -5              6
therefore the co ordinates of midpoint are(-5,6)
 
        
             
        
        
        
Answer:
v=2 s=5
Step-by-step explanation:
a) v=volleyball s=soccer
s × v = 7
" the soccer (s) practice lasts 1 hour (1) more than (+) twice as long (2) as the volleyball (v) practice; this simplifies to: s = 1 + 2v 
b) substitute equation for soccer for s 
(1 + 2v) + v = 7
solve for v
1 + 3v = 7   (2v + v = 3v; that's where the 3v comes from)
we subtract 1 from both sides
3v = 6
we divide 3 from both sides
v=2
solve for s
since we know what v equals, we substitute it in
s + 2 =7
subtract 2 from both sides
s = 5
 
        
             
        
        
        
Answer:
The volume of a sphere is 2/3 times the volume of a similar cylinder
Scale factor : 2/3
Step-by-step explanation:
Let us consider a sphere of radius r. The volume of the sphere will be given as 

Similarly, let us consider a cylinder with its height being twice the radius of the sphere. We will have its volume given as:

but h = 2r
Hence we have

We can divide the two volumes to get a constant that links them together

this will give us 2/3
Hence the scale factor for Vol sphere: Vol cylinder is 2/3
