Formula for length (distance) between two points is
d=√(x2-x1)∧2+(y2-y1)∧2
In our case the y coordinates is the same which means that this line is parallel with x axis.
You can get length if just subtract l=7-(-3)=7+3=10 units
Good luck!!!
Answer:
62°
Step-by-step explanation:
Complementary angles by definition are two or more angles that add up to 90°. So we must do 90°-62° to get the missing angle which is 62°.
Hope that helped.
Answer:
minutes
Step-by-step explanation:
We have been given that the average wait time at a hospital increased by 70%.
Initially average wait time was <em>m </em>minutes. But later it increased by 70%.
Let there are <em>n </em>number of patients and it takes <em>t </em> minutes to examine each patient.
So the initial average waiting time is:
minutes
After the outbreak the waiting time increased by 70%. So the new waiting time should be the sum of initial waiting time and additional waiting time that is:
New waiting time = 70% 
+ 
184 - 124 = 60
so it has grown by 60 in 18 months. That is 3 1/3 per month.
so Number of citizens depending on month is 124 + (1 1/3)n
or 124 + 4n/3:
At population 1000:-
124 + 4n/3 = 1000
4n/3 = 1000-124
n = (1000-124) * 3/4 = 657 months
