Thanx, Dr101....!!!!!

Note that this is a right triangle  because

3.3^2 + 5.6^2  = 6.5^2

10.89 + 31.36  = 42.25

So....the hypotenuse [6.5 cm] is the diameter....so....the radius is (1/2)  of this  = 3.25 cm

Here's a pic :

Which rat is unrelated to rat A

\(Rat \ B \ and \ rat \ D\)

@Melody

These all could be possible, but I was leaning towards a wooden dock

8 legs, sometimes less, sometimes more.(The wooden posts)

I sit still until I rot(Wood hint)

I cannot walk(Another hint towards the answer)

But all of those could be correct if there was more than one answer!

Move the .--> two places.

Am I one of them Jacob??

There is NO equation!. Find out the "Exchange Rate" between the "Pound" and the "Peso". As of today, 1 Pound = 25.90 Pesos. If you have 1,000 Pesos, then: 1,000/25.90 =~38.61 Pounds.

b^2 - 5b - 6  =

(b - 6 ) ( b + 1)

1/8  = 3/24

5/6 = 20/24     ...so....

1/8 + 5/6  =

3/24 + 20/24  =

23 / 24

40-(x*20)=7 This is NOT an inequality but an equation!.

40 - 20x = 7

-20x = 7 - 40

-20x = -33 divide both sides by -20

x = -33/-20

x= 3 + 13/20 =3 13/20

Your sequence should read:

2, -4, 8, -16, 32, -64, 128, -256, 512......etc. The common ratio being -2.

Thank you

2x^2  - 5x - 12  = 0   factor out 2

2 [x ^2 - (5/2)x - 6]  = 0           divide by 2

x^2 - (5/2)x - 6  = 0        add 6 to both sides

x^2  - (5/2)x  = 6 

Take (1/2) of (5/2) = (5/4)  ....square this   =  25/16....add to both sides

x^2 - (5/2)x + 25/16  = 6 + 25/16         mutliply back by 2

2x^2 - 5x + 25/8  = 12  + 25/8

In mathematics, a conjecture is a mathematical statement which appears to be true, but has not been formally proven. A conjecture can be thought of as the mathematicians way of saying “I believe that this is true, but I have no proof yet”. A conjecture is a good guess or an idea about a pattern.

Many thanks for your input here - but the question is based on annual, not monthly interest, and to include the principal (£5000) as well as the monthly payments.  Also, how do work this out using a scientific calculator? - your help on this would be much appreciated.

C = 2 * pi * r    →     200  = 2 * pi * r  →     200 / [2 * pi ]  = r  →

100/pi  = r ≈ 31.83  units

what up !!!

2−15(−x+1) = 3+2(5−x)     .....simplify......

2 + 15x - 15  = 3 + 10 - 2x

15x - 13  =  13 - 2x       add 13, 2x to both sides

17x  = 26         divide both sides by 17

x = 26 / 17
