Answer: 0.122449
Step-by-step explanation:
If one side is 1/7, first convert that into a decimal, which is 0.14286. Than square that 0.14286 x 0.14286= 0.020408. That’s the area of one square. Now multiply that by 6 (the number of sides in a cube) and you get 0.122449.
Step-by-step explanation:
A = A₀ ½^(t / T)
where A is the amount left, A₀ is the original amount, t is time, and T is the half life.
4 days is 96 hours, so the amount left is:
A = 600 ½^(96 / 15)
Answer:
X = 5 3/8 (5 and 3 eighths)
Step-by-step explanation:
4/5x = 5 1/5 - 9/10
4/5x = 43/10
x=43/8
x= 5 3/8
Answer:
A. x = 6
Step-by-step explanation:
I know this can look intimidating. But don't let that stop you. First the little 2 above the x means 'squared' or 'to the power of'.
And all this is asking for is 'what squared = 36?' And square is really just a number times itself. For example 3 squared is 9, or 3 x 3 = 9. A really simple way to do this if you don't know the answer by looking at it is to just square root of 36. And you can do that on your calculator. (It is this little symbol, √) and you just click 36 and then √ and it should give you 36. And then to check if you are right, just do 6 squared, or 6 x 6.
Good luck!
