solve n mod 32 = 30
n mod 54 = 44 for n

n = 864C + 638 =1,502 when C=1

n = 864C + 638 =2,366 when C=2 

Both of these solutions are valid.

what is the area of a circle with a radius of 5

\(A=\pi r^2\)

\(r=5\)

\(A=\pi \times 5^2\)

\(A=78.5398\)

Two sides of an obtuse triangle are 16 and 21. How many possible integer lengths are there for the third side?

a = 16

b = 21

\(\sqrt{16^2+21^2}< c < (16+21)\)

\(26.4 < c < 37\)

\(\mathbb L= \ c\in \left \{27,28,29,30,31,32,33,34,35,36 \right \}\)

\(10 \ possible \ integer \ lengths \ are \ there \ for \ the \ third \ side.\)

Let n be the number that each student donates

Then  

z * n  = 300    →  n  = 300/z

So....the number of books she will have left is....

127 - n  = 

127 - 300/z

how do i work this equation into a parabola/straight line? y=x+2 ; f(x)=x^2

Huh?

The first on IS a straight line  AND the second one IS a parabola.

What is 81\(blank/4)=9? I can't figure out blank!

I assume that you mean

 81/(blank/4)=9?

\(81 \div \frac{x}{4}=9\\ 81 \div \frac{x}{4}\times \frac{x}{4}=9\times \frac{x}{4}\\ 81= \frac{x}{4}\times 9\\ 81= \frac{9x}{4}\\ 81\times \frac{4}{9}= \frac{9x}{4}\times \frac{4}{9}\\ 9\times4= x\\ x=36 \)

OR

I could have just said

81/9=9

so

blank/4=9

so

36/4 = 9 so the number must be 36

what is the answer 5 5/8 * 8 4/9?

\(\large 5\frac{5}{8}\times8\frac{4}{9}=\frac{45}{8}\times\frac{76}{9}=\frac{5\times19 }{2}=\frac{95}{2}=47\frac{1}{2}\)

c^2 = 5c      divide both sides by  'c'

c = 5

x^2 + 13x +42 = 0   Use Quadratic formula ...or factor it to

(x+7)(x+6) = 0     so x+7 = 0     means x= -7     x+6 = 0  means x can also = -6

x^2-4x-21   = 0    factors to  (x-7)(x+3) = 0     so x =  7 or -3

Its obviously 87/100

Let  x = 3.2272727272.....

100x = 322.72727272....

10000 x = 32272.72727272...

10000x - 100 x  = 9900x   =  32272.72727272...  - 322,727272...  =  31950

x = 31950/9900   = 3  2250/9900=    3  5/22

FV = P ((1+i)^n-1) / i       where i = 3%/12 = .0025  n = 12

3000 = P ((1+.0025)^12 -1) / .0025      

P =$ 246.58 each month for 12 months

Not everyone sir I don't see why a baby would be teaching themselves calculus.…3+10 = 13

Distance from the origin for point (x,y) is    sqrt(x^2 + y^2)    (like pythagorean theorem)

59 /  8835        59 is prime and doesn't evenly divide 8835...so...this is simplest form ≈ 0.006678

No we're not....some of us are 4......

Let the boat rate in still water [ in kph]  = B  and with the current  = B + 3

Let the boat rate against the current  = B - 3

And    Distance / Rate  = Time......but it takes twice as long against the current as  with the current

So

2 [ D / (B + 3)]  = D / ( B - 3)   cancel the D's

2 / ( B + 3)  = 1 / ( B - 3)      cross-multiply

2 ( B - 3)  = B + 3

2B - 6  = B + 3   rearrange

B  = 9 kph
