You can use the proportion:     degrees / 180  =  radians / π

     --->     degrees  =  radians · 180 / π

     --->     radians  =  degrees · π / 180

You can set up a proportion:    75% / 100%  =  15 / 

    --->     .75 / 1.00  =  15 / x

    --->     .75 · x  =  15                (multiply both sides by x)

    --->     x  =  15 / .75                (divide both sides by .75)

    --->     x  =  20 questions   

The distance is just 4 - (-2)  = 6

(a + 4)^2 - (a - 4)(a + 4)    expanding, we have

a^2 + 8a + 16 - [a^2 - 16]  =

8a + 32

"is" means "="    48% = .48   "of" means "multiply    let the number  = "N"     so we have

7800 = .48N     divide both sides by .48

7800 / .48 = N = 16,250

We have

7000(1 + .062/4)^(4 * 8)  = about $11451.32

So, let the integers be n, n+1 and n+2......and we have

3(n+2)  = n + n + 1

3n + 6  = 2n + 1   subtract 2n, 6 from both sides

n = -5

n+ 1 = -4

n + 2  = -3

Check

3(-3)  = -5 + -4

-9 = -9

To find the percent.......divide 25 by 60........you will get a decimal answer.......move the decimal two places to the right and add a "%" sign....that's it...

log5+3logx+logy .......using log.... a + log b = log(ab)

We have

log5+logx³+logy =

log (5x³y)

"Of" means multiply  ....   65% = .65

So

.65 * 7200 = 4680

2x-x^3+5=0    the easiest way to solve this is by graphing

l x + 4 l  > 0     take the expression out of the absolute value 

We have

x + 4 > 0      subtract 4 from both sides

x > -4

We also have

x + 4 < 0     subtract 4 from both sides

x < -4

So the solution is  (-∞, -4) U (-4, ∞ )

My understanding is that 'div' gives the quotient for integer division and 'mod' gives the remainder.

So, when 15 is divided by 6, the integer quotient (div) is 2 and the remainder (mod) is 3.

15 div 6 = 2

3 div 6 = 0     (integer quotient is 0, remainder is 3)

If I'm correct, then 20 mod 0 is undefined because division by zero is not allowed.

For me 'minint', or 'min int', is the smallest (therefore, usually negative) integer for a particular computer configuration. This value depends upon whether you have an 8-bit, 16-bit, 32-bit, 256-bit, etc. system.

Additions or corrections, anybody?

24 • 3 = 72

24 • 4 = 96

800 + 16x = 720 + 21x

800 - 720 + 16x = 720 - 720 + 21x

80 + 16x = 21x

80 + 16x - 16x = 21x - 16x

80 = 5x

16 = x

What a hash they must make of the formula vol of sphere = 4/3𝞹R³ 

Don't worry, Anonymous......parentheses and brackets seem optional, too!!!

 I'm slowly coming to the conclusion that there must be a whole generation of junior HS mathematics teachers in the US who have taken it upon themselves to simplify mathematics where they think it is unnecessarily fastidious, and their first target has been the / division operator.

Thanks, Melody.....!!!!
