Now the question becomes.
Does any squared number contain the digit 7 ?
If so what is the first squared number that contains the digit 7 ?
what four digits do not appear in the first twenty square numbers?
1,4,9,16,25,36,49,64,81,100
121,144,169,196,225,256,289,324,361,400
There is the first 20 squared numbers
7 is the only digit not there.
Yes maybe my lemonade is lite. :)
The key word here is WATER
1mL WATER weighs 1gram. Also 1mL of anything has a volume of 1cm^3
1mL Lead weighs approximately 11 grams

How much the amount will be after three years if deposited $500 per month for three years @4%per annuam. kindly show me the calculation formula also.
This is if you put the money in at the end of each month.
C=500
i= 0.04/12=0.00333333333333333
n=3*12=36
You can do the substitution yourself.
how much would your monthly mortgage be if you owe 180,000 @ 3% amortized over 25 years.
Just use
C is what you are looking for
i is 0.03/12 = 0.0025
PV=180000
n= 25*12 = 300
\(180000=C*\left(\frac{1-1.0025^{-300}}{0.0025}\right)\\\\ 180000=C*210.87645\\\\ C=180000\div 210.87645\\\\ C=853.58 \)

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
-------------------------------------------------------
If the radius is 17.6 feet then the circumference would be 2*pi*17.6 = 110.6 feet
and the diameter would be 35.2 foot so your numbers still don't make sense.
Lets say your radius is 17.6 feet
the area is pi*17.6*17.6 = 973feet^2
Each tarp is 5.6*7.6 = 42.56 feet^2 and you have 10 of them so that is 425.6feet^2
So no there will not be enough tarps.
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 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%
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! :))
