2/3 = 0.6666666666666667 = 0.67

0.67 * 0.67 = 0.4489

10 * 0 = 0, as you can't multiply by 0. Then +1 = +1.

Answer: 1.

I got 1.375301942 just from plugging the whole thing ito my calculator.

(110-90)/[(110+90)/2]/(12-8)/[(12+8)/2]

= (20)/[(200)/2]/(4)/[(20)/2]

= 20/[100]/4/[10]

= 0.2/4/10

= 0.05/10

= 0.005

Oh boy I can do this problem! =D

y = x² + 8x - 9

We need to take the derivative of this. That will tell us the slope of the graph of this function at any point. Take the derivative using the power rule.

y' = 2x + 8

Set y' = 0 to find all the places where the slope of x² + 8x - 9 is zero.

0 = 2x + 8

-8 = 2x

-4 = x

So when x is -4, the slope of x² + 8x - 9 is zero. That means it is either a maximum, minimum, or inflection point. To figure out which one, take the second derivative.

y''= 2

Since y'' is positive when x is -4, that means the graph is concave up, which means x = -4 is the minimum.

Haha, I don't know how to do this problem but I thought it was funny that her name is Ima Vain and she is applying makeup hourly, lol. (Sorry I'm no help)

Let's work through it again....I assume you want the interest rate ??

Assuming yearly compounding, we're using

4000 = 2000(1 + r)^4      where r is the interest rate in decimal form

Divide both sides by 2000

4000/2000 =   2  =  (1 + r)^4

2  = (1 + r)^4       take the 4th root of both sides

2^(1/4)  = [ ( 1 + r)^4]  ^ (1/4)      the right side simplifies to   1 + r

2^(1/4)  = 1 + r      subtract 1 from both sides

2^(1/4)  - 1 =  r   

1.1892  - 1  = r

.1892  = r  ≈ 18.92%   interest rate

That's OK, DR........maybe MysticalJaycat can provide us with a less "math-intensive" story next time.........

Good job chris

i just read and ignored math 😆

We need to solve this for "N"

1337(1/2)^(N - 1) = 1

(1/2)^(N - 1)  = 1/1337

log (1/2)^(N - 1) = log (1/1337)

(N - 1) log(1/2)  = log(1/1337)

N - 1  =  log (1/1337)/ log (1/2)

N  = log (1/1337)/ log (1/2) + 1 ≈ 11.384

So....the 11th term  is 1337(-1/2)^(10)  ≈ 1.305

And the 12th term is 1337(-1/2)^11  =  -.653

And.....the odd terms from 1 - 11  inclusively  will be positive and > 1....and there are six of these

If you keep on mltiplying by -.5, you will eventually get to 6 POSITIVE ones that actually count.

-2 - 4 + -8

= -2 - 4 - 8

= -6 - 8

= -14

HAHAHA!!!!....good one, Guest.......

Add the sides....subtract this sum from the perimeter

[3x - 4] + [2x + 5[   =

5x + 1

So

[9x + 6]  - [ 5x + 1]  =

4x + 5   =  length of the remaining side

=1/(9.779234309486079*10^78)

= a very tiny number

hi there,

the answer to that is 9702.

note: ?>0

 I turn off the higher power by saying,  "Amen."

Here's how I do it :

Position the cursor one space after the power you entered......click on the T_x symbol next to the x² symbol.....then, hit the space bar.....

No,die please

7500/3 = 2500

So 2500 of the shippings are peanut free.

7500 - 2500 = 5000

So 5000 of the shippings are mints/store brand.

If I understand your question correctly, you are saying that the company makes money on 60% of peanut free chocolates and 50% of mint/store brand chocolates. But we want to know how much the store makes, not the company. That means the store makes money on the remaining 40% of peanut free chocolates and the remaining 50% of mint/store brand chocolates.

40% of 2500 = (0.4)(2500) = 1000

50% of 5000 = (0.5)(5000) = 2500

1000 + 2500 = 3500

So the store makes money on 3500 shippings every day.

43A + 22 =101B + 64 =211C + 30, solve for A,B,C.
A=1,065,  B=453,    C=217, so that:
43 x 1,065 + 22 =45,817 The smallest positive number.
LCM {43, 101, 211} =916,373. So, the general form is:
916,373D + 45,817. And for D=0, 1, 2......etc. We have:
45,817 The smallest positive number.
962,190
1,878,563.......etc.

If you have to explain to us what to do, or how to solve the problem, why don't try it and let us know what you get!. Then, will be able to judge if you understand the problem or not. Good luck.

I'm not sure what you mean by "2 widths and 2 lengths." A rectangular prism should have three dimensions—length, width, and height. And by "cm(2)" do you mean "cm²" ?

\(x = \sqrt{100}(6051)\)

x = (10)(6051)

x = 60510
