Answer:the total number of registered doctors is 250463
Step-by-step explanation:
Let x represent the total number of registered doctors
In a recent year 21.6% of all registered doctors were female. It means that the number of registered female doctors would be
21.6 /100 × x = 0.216 × x = 0.216x
if there were 54,100 female registered doctors that year, it means that
0.216x = 54100
x = 54100/0.216 = 250463
Answer:
146 miles
Step-by-step explanation:
hope this is correct
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
Ok let us assume x= the width of the table top
the length is 4 times the width meaning we are multiplying 4 and the width
which is x
length = 4x
your first equation would be the following:
4x+4x+x+x= whatever the perimeter is
if you drew a rectangle it would help you understand the above.
this represents the perimeter of the tabletop because we know the width is x. if you drew the rectangle there wouldn't be 1 width. opposite to the width is another line. same with the length. the length is 4x again there are 2 because in a rectangle there are 2 sets of parallel lines. that is why your equation would be 4x+4x+x+x= whatever the perimeter is- you could simplify this equation and write:
10x= whatever the perimeter is
x basically means 1x but in math we generally don't write that because we tend to write most things in simplest for.
hope this helps :)

The graph is C, or the graph down left.
This is because the other graphs lack the same vertex.
