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
I saw this same type of question and page but with different numbers just 5 minutes ago...
Anyway here’s the answers:
1) Complementary
3x+1+44=90
3x+45=90
3x=45
x=5
2) Vertical
Ignore everything about the work. The answer is 120 degrees because they’re vertical angles.
3) Supplementary
15x-5+110=180
15x+105=180
15x=75
x=5
And I can’t see the last question clearly
