Answer:
Step-by-step explanation:
after one year= 4/100 times 2000
= 80 people
after 15 years= 80 times 15=1200 people
2000+1200=3200 people
Henry needs to sale 14 rings for his revenue to equal his expenses.
Step-by-step explanation:
Given,
Selling price of ring = $8
Expense on one ring = $1.50
Cost of supplies = $91
Let,
x represent the number of rings.
Expenses = 91+1.50x
Revenue = 8x
Equal expenses means;
Revenue = Expenses
Dividing both sides by 6.5
Henry needs to sale 14 rings for his revenue to equal his expenses.

Answer:
The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm
Step-by-step explanation:
The lengths of side of the triangle are in ratio 8:9:10
Perimeter of triangle = 108 cm
We need to find length of sides of triangles.
The formula used is:
The length of side of triangle can be expressed as:
First side= 8x
Second Side =9x
Third Side=10x
So, finding x and then calculate length of each side
So, value of x = 4
The length of sides of triangle will be found by putting value of x at each side.
First side= 8x = 8*4 = 32 cm
Second Side =9x= 9*4= 36 cm
Third Side=10x = 10*4=40 cm
So, The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
