Seismometers measure: Body and surface waves
Do most damage above ground: surface waves
Can travel through liquids solids and gases: S waves
Only travel through solids: P-waves
X = No. of professors
x + 14x = 37,500
(No. of professors + 14 times the no. of professors = total)
Add.
15x = 37,500
Isolate x by eliminating 15.
15x/15 = 37,500/15
x = 2,500
There are 2,500 professors in the college.
37,500 - 2,500
(Total - no. of professors = no. of students)
= 35,000
There are 35,000 students in the college.

Answer:
5.67
Step-by-step explanation:
- 68.0052 divided by 12 = 5.6671
- The hundredth place is two digits to the right of the decimal point.
- To round this look at the third number to determine whether the 6 in 5.6<u>6</u>71 is rounded to 7.
- The third digit to the right of the decimal is greater than 5 so the number is rounded to 5.67
Ok, so the discount is given in a percentage, in this case 10%. The sale price is going to reflect 10% of the original price minus the discount, so...
Sale $ = original$ - original $ x .10
If we use some algebra, we can reorganize the equation to solve for the original price...
Sale $ = original$ - original $ x .10
Sale $ = original$ (1 - .10)
Sale $ = original$ x .90
original$ = sale$/.90
So now we can plug in our values
original price = 50/.90
original price = 55.55555 = $55.55 to the nearest nickel
Remember
(x^n)^m=x^(mn)
(x^4)^2=x^(4*2)=x^8
