Answer:

$1.69\times 10^3$ feet/million year

Step-by-step explanation:

We are given that

Elevation of top of basalt in valley =4100 feet

Elevation of bottom of basalt in valley =2100 feet

Age of top of basalt in valley=15000 years

Age of bottom of basalt in valley=1.2 million years= $1.2\times 10^6 years=1200000 years$

We have to find the rate of basalt filling in the valley in feet per million yeas

Rate of basalt filling in the valley= $\frac{Elevation\;of\;top\;of\;basalt\;in\;valley-elevation\;of\;bottom\;of\;basalt\;in\;valley}{age\;of\;bottom\;of\;basalt\;in\;valley-age\;of\;top\;of\;basalt\;in\;valley}$

Rate of basalt filling in the valley= $\frac{4100-2100}{1200000-15000}=\frac{2000}{1185000}=1.69\times 10^{-3} feet/year$

Rate of basalt filling in the valley= $1.69\times 10^{-3}\times 10^{6}=1.69\times 10^3$ feet/million year

Since you paid $3,625,you are paying $4323 in four years.
The easy way to do this is 4343(1+0.122)^4
you're paying 1212.6 per year which means you're paying $4850.4 so the total cost is $8475.4

Answer:

3(60/10)

Step-by-step explanation:

10 students require 3 cookies, which you already know. So, since you need to find for 60, you can divide 60 by 10 into 6. Then, 6x3 will equal 18. Or, you can say:

10=3

20=6

30=9

40=12

50=15

60=18

10x2=3x2 and so forth....
