25 * $250M  = $ 6.25B    .....that's some expensive real estate  !!!!!

Hit the "2nd" button on the calculator and find the "atan'  key  [ tangent inverse ]

Very nice, Alan  !!!!

I like this one  !!!

The first four terms are :   9, 12, 15, 18

a )  GC =  8/srt(2)

And triangle CFD  has the same area as the square EFCG =  (8 sqrt(2) )^2 =  128 units^2

b)  The area of the unshaded part   =  2.5 times the area of square EFCG = 2.5 (128)  = 320 units^2

Since PS = PT, then angles PST and PTS are equal

And the measure of either  one =  [180 - 16] / 2 = 164 / 2 = 82°

And

m<RSQ + m<PST +  m<SPT +  m<QPT   = 180°     .....    by substitution, we have  ....

43°    +     82°   +  16°  + m<QPT   = 180°     simplify

141° +  m<QPT =  180°      subtract 141 from each side

m<QPT  = 39°  =  " y"

m<ADB = 48

And by the Exterior Angle Theorem :

110 = m<BAC + m<CAD + m< ADB   .........and we have

110 = m<BAC  +  27  + 48    simplify

110 = m<BAC + 75     subtract 75 from both sides

110 - 75 = M<BAC  =  35°

:

The volume of water in Tank A = (3/4)(12)(25)(20) = 4500cm^3

And the base area of  Tank A -= 12 * 25  =  300 cm^3

And since the base area of Tank B is twice that of Tank A, its capacity is (600)cm^3

And we want to know this :

300h + 600h = 4500     where h is the equal height of water in both tanks

900h = 4500    divide by 800 on both sides

h = 5cm

Do this as follows:

i am not sure but i think it is an imposible equation because no matter what you do you will end up with t=xt wich unless x = 1 is impossible , in wich case x does not equal to 1 . it can also work if x=0 and t = 0 .then it solves for any x though . Not quite sure, hope i helped a little ...

No.  2^1 = 2.  However, 2^0 = 1

I, too, was puzzled at first.  I wondered if it was a coincidence due to the choice of numbers used or if it was more generally true.  A little analysis shows it is generally true - see below:

So, what would you like calculated? The monthly payment, its FV?

1-If you want the monthly then it is:$532.35

2-If you want the FV then it is:$26,809.18

13939.43 ( 1 + .22/12)³⁶   =  $ 26809.18

A = pi * radius²

O + M + Q + M = 37 AND O + Q + Q + M = 41 AND M + O + Q + O = 46 WHAT IS Q + O +M + Q

We have the following system :

2M + Q + O   = 37

M  + 2Q + O =   41

M + Q   + 2O  = 46

Subtracting the second equation form the first, we have

M - Q   =  -4    →   Q = M + 4  

Subtracting the third equation from the first, we have

M - O  = - 9  → O  = M + 9   

Substituting into the first equation, we have

2M + [ M + 4] + [ M + 9 ]  = 37   simplify

4M = 24   →    M = 6

And Q = 6 + 4 = 10

And O = 6 + 9   = 15

If we are only talking about a triangle in the first quadrant bounded by the tangent line and the two axis.....an isosceles triangle can be formed when :

3/a^2 = 3a / 2    cross-multiply

6 = 3a^3

2 = a^3

a = (2)^(1/3)

See the graph, here :  https://www.desmos.com/calculator/rmr2qlx29k

Two sides of the triangle wil lbe about 1.89 units in length......these sides will fall on both of the coordinate axis

If there's one number by which you can multiply both the "top" and "bottom" of a given fraction to successfully turn it into another given fraction, then those two fractions must be equivalent.

To turn 2/7 into 6/21 we simply multiply BOTH the top AND bottom of that first fraction by 3. So the pair of fractions are equivalent fractions.

To turn 3/5 into 6/25 we would need to multiply the numerator by 2, but the denominator by 5. Because this would need different numbers for multiplying the top and bottom, we have to conclude that 3/5 and 6/25 are NOT equivalent fractions.
