You must be buying the Lite lemonade, Melody!

The PV of the annuity as of today is=$3,815.40

In 5 years time its value will be        =$5,953.96

5+5=10

I have a 33 foot round pool, with a radius of 17.6 feet from the center to the edge.  Not the dameter as stated.  Sorry for the mistake.  I purchased 10 tarps of square size of 5.6 feet x 7.6 feet.  Will the 10 tarps tied together cover the pool or will more tarps be needed?  Thank you all for your help

Did you make a mistake somewhere? If the circumference is 33, then the diameter would have to be 33/Pi=10.50 inches. If the diameter is 17.6, then the circumference must be: 17.6 X Pi=55.29.

Check to see where the mistake is before we can help you answer the question.

33' circumference with a 17.6 dameter need to fit a number of 5.6 x 7.6 square tarps upon this circle.  How many tarps will be needed for this project?

Your question makes no sense.

If the circumference is 33' then the diameter is not 17.6'

And

How can a tarp be square if the sides have different lengths?

Even if the numbers did makes sense, can the tarps be chopped up or what?

The answer is 1345000000000 :P

Don't know what???

prime factors of 66=2 X 3 X 11

The number y is 125% OF another number. What percent of 8y is 5x?

I assume that you mean y=125% of x

so  y=1.25x

The question becomes What percentage of 8*1.25x is  5x

(5x) / (8*1.25x) *100 %  =  (5 / 10) *100%  =  50%

(4/11)x 55 are nickels  = 20 are nickes  =          $1.00

(2/11) x 55 are dimes =  10 are dimes =            $1.00

(5/11) x 55 are quartes  = 25 are quarters =      $6.25

                                                                          --------

                                                                           $8.25  

                                                              =  total value of all the coins

Alice, Bernice, Celine, Devi had a total of 156 stamps. Alice lost 22 stamps and Bernice bought 16 stamps. If Devi had 3 times the number of stamps she originally had, then all of them would have an equal number of stamps. How many stamps did Celine have at first?

Let w = Alice's original number of stamps, x =  Bernice's  original number of stamps, y = Celine's original number of stamps and z = Devi's original number of stamps

And we have this system :

w + x + y + z = 156    (1)

y = 3z   (2)

w - 22  = 3z   → w = 3z+ 22  (3)

x  + 16 = 3z  →  x = 3z - 16    (2)

And substituting (2), (3) and (4) into (1), we have :

[3z + 22] + [ 3z - 16] + 3z + z = 156      simplify

10z  + 6  = 156

10z = 150

z = 15

Celine had/has 3(15)  = 45 stamps 

Check

67 +  29 + 45  + 15  = 156

i believe  its 9 because 9x2=18 or

1/2x9/1

=18/1

=18

The pouch contains $8.25 worth of coins.

Since each ml of water weights 1 g, 0.1 liters of water = 100 grams. As well, "kilo" means "thousand". So 1 kilogram (kg) = 1000 grams.

(4 + 2 + 5)k = 55

11k = 55

k =5

4x5 = 20 nickels = $1

2x5 = 10 dimes = $1

5x5 = 25 quarters = $6.25

total value = $8.25

1000 grams

0 is an integer and thus it is a rational number.

\(0=\dfrac 0 1\)

is the ratio of two integers

This comes from this fact: Density=Mass/Volume. Density of water is 1 Kg/L, or 1 gm/cubic cm.

Buy cubic cm=1 ml, therefore Density of water=1=1Kg/1L=1000grams/1000milliliters:

Therefore: 1 milliliter=1 gram.

therte is not an answer for this

Let T be the total number of seats before the additional number were added

And let R be the revenue collected before the additonal seats were added

So we have this system

.75T(40) + .25T(75)  = R   (1)

.75T(40) + (1460 - .75T)(75) = R + 21900  (2)

Substituting (1) into (2), we have

.75T(40) + (1460 - .75T)(75) = .75T(40) + .25T(75) + 21900   simplify

 109500 - 56.25T  = 18.75T + 21900

75T =  87600

T = 1168

And after the seats were added, the number of VIP seats = (1460 -  .75*1168)  =   584

And the % of VIP seats after the seats were added = 584/1460  = 40%

Hi CierDreaj

You were on for hours after I posted this. I am wondering why you did not comment? 

Was it enough? Did you need more help? Or what?

We like feedback around here you know, interactive teaching and learning is the best kind there is!  :))

Are our guests telling us that 100ml of molten lead weighs the same as 100ml of lemonade?

That does not sound right ://

9y2+8x=12

y = -2/3 sqrt(3-2x) and y = 2/3 sqrt(3-2x)

2x+3y=4

y = -2/3(x-2)

18/24 (1-0.7)^3

=0.02025=81/4000
