Answer:
In five years, the enrollment would have been 10,724 students
Step-by-step explanation:
The general depreciation formula is given as;
P = I( 1 - r)^t
where P is the present population
I is the initial
r is the rate of depreciation = 4.5% = 4.5/100 = 0.045
t is 5 years
substituting these values;
P = 13,500 (1- 0.045)^5
P = 10,723.84
Let the two numbers be x and y where x is greater than y.
So;
x + y = 3.1 ... (i)
2x - 3y = 7 ... (ii)
This forms a set of simultaneous equations (i) and (ii)
Solving the simultaneous equations by elimination;
We multiply (i) by 2 and (ii) by 1 to get:
2x + 2y = 6.2 ... (i)
2x - 3y = 7 ... (ii)
Subtracting (i) - (ii) we get;
5y = -0.8
y = -0.8/5 = -0.16
x = 3.1 - -0.16 = 3.26
The numbers are 3.26 and -0.16.
Answer:
2= 95 degrees
3= 25 degrees
1= 60 degrees
5= 25 degrees
4= 95 degrees
Step-by-step explanation:
2) Straight line is 180 degrees so
180-85=95 degrees
3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.
1) A triangle is always 180 degrees, 95+25=120 180-120=60
5) Its another corresponding angle to 25
4) Straight line is 180 degrees 60+25=85 180-85=95
Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4
