Oh. But it's automatically on degrees.

They may be refering to the calculator on this site.

I might be wrong but its usually in the shift -> mode section

Its usually shift -> mode -> 3 in casio calculators :)

There should be a little switch indicating Rad (radians) and Deg (degrees)

Degrees are obsolete in later maths...

lf you have a school with grades 1st - 8th you have 8 grades.

Just divide 4,800 students by 8 grade levels to get the quotient...

600 students per grade level.

Yep. Anything to the power of two cannot be negative UNLESS you stated it this way.

-(n)^2

That implies you multiply by neagtive one after you use the exponent.

The ORIGINAL price was  499.95 +30 = 529.95

30 dollars   is what percent of 529.95?

30/529.95 x 100% = 5.66% discount

Side length of the cube is given as   3 * w = 3w

Volume of the cube is 3w x 3w x 3w  = (3w)^3

Simplified = 27 w^3

Thank you.

Just input that into the calculator you'll get a fraction and a decimal form.

16 new players over 80 original   16/80 x 100% = 20% increase

Volume of a square pyramid = b^2 h/3

now increase b by 50%

New volume =  (1.5b)^2 h/3

                     = 2.25b^2  h/3

                   =  .75 b^2 h

Thank You So Much!

No, but she has stood here the longest.

3 x 3^8 = 3^9 ft

there is no solution.

x^2-6x+5

You must look for two numbers that multiply to +5

SO they will have to be BOTH negative or BOTH positive (becausee they multiply to a positive)

They also have to add to -6     SO they both must be negative.

The only posibility is  -5 and -1

S0

x^2-6x+5 = (x-5)(x-1)

12 + 12 + 36 + 36 + 24  =  120   in

15. I learned that before I even enrolled in school
