Use photomath it'll solve it for you easily and it's always correct work for any kind of math
8/x^4
I multiply to get everything out of the Parentheses.
Then a lot more steps
But the answers is 8 over x to the power of 4
Ok what do we know.
when the kettle is full its 2900g
when its half full is 2050g
that means that half the weight of water in the kettle was 850g so the other remaining half has to be 850g
850+850=1700
1700g is the weight of the water
but we want to know the weight of the kettle when its empty so you had 2900g when the kettle was full lets say you poured all 1700g of the water out you would be left with...
2900-1700= 1200g
this means the kettle when empty weighs 1200g
Compound Interest Formula: A = P(1 + r/n)^(n·t)
A = final amount r = rate, as a decimal (.021) t = number of years (17)
P = initial amount (2914.72) n = number of times compounded per year (365)
A = 2914.72(1 + .021/365)^(365·17) = $4165.20
Interest earned: $4165.20 - $2914.72 = $1250.48 <----- Answer
You might want to recalculate this, attempting to handle leap years, by replacing the number of times compounded per year with 365.25 and see if that has an effect
In 6,289,002 the 6 is located in the millions place and 2 is next to it. Since 2 isn't bigger than 5, the 6 stays the same and the rest of the numbers to the right turn to zeros. So, 6,289,002 rounded to the nearest million is 6,000,000.
