a tin mine is estimated to have tin reserves worth two million ringgit. if the monthly extraction is 5% of the value of the rese
rve the month before, find the value of the tin reserves after two years.
1 answer:
Month_1 Value = Month_0 Value * 0.95
Month_2 Value = Month_1 Value * 0.95 = Moth_0 Value * 0.95*0.95 = Month_0 Value * 0.95^2
Month _n Value = Month_0 Value * (0.95)^n
After 2 years ==> n = 24
Month_24 Value = Month_0 Value * (0.95)^24 = 2,000,000 *(0.95)^24 = 583,978.05

Answer:
Try 250 = 70x + 50, or y = 70x + 50.
Step-by-step explanation:
He made 250 total. The variable is how many cars he washes. The y-intercept is 50. Therefore, either 250 = 70x + 50, or y = 70x + 50.
I think you doubled them
ratio of dogs to cats=3:2
30 animals total
3+2=5 units
30=5unit
divide by 5
6=1unit
dogs=3 unit
6=1unit
times 3
18=3unit=dogs
18 dogs
Change 15/20 to 3/4
Now we have
multiply 6 to 3= 18 ÷ 4 = 4.5
x = 4.5
