Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction
21.192 can be written as 21 192/1000 so yes its rational
i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.
Hope this helps :P
We have 4 people in our home
so total bought 360 pounds of hamburger
each ate 2/3 pound every day
so 360-(amount eaten per day) times (number of days)=0 (0 because we want it to be gone)
number of days=x unknown
amount eaten per day=(number of people) times (amount eaten per person per day)
amount eaten per day=4 times 2/3 lb=8/3
360-8/3 times x=0
360-8/3x=0
add 8/3x to both sides
360=8/3x
multiply both sides by 3/8
1080/8=x
135=x
it would take 135 days or about 4 months or 1/3 year, assuming that my family doesn't get tired of it and that my reletives don't visit and take a whole bunch to bring home.
4 people takes 135 days
Answer:
10%
Step-by-step explanation:
We have procent:
520 —-> 100%
572 ——> x%
So, it is:
520*x=572*100
X=57200/520=110%
110%-100%=10%
Answer:
Step-by-step explanation:
Assuming we are doing an arithmetic sequence
It depends on where you start
If the first term is a₁ and the term number is n
each subsequent term is
aₙ = a₁ + 4(n - 1)
a₁₀ = a₁ + 4(10 - 1) = a₁ + 36
a₅₃ = a₁ + 4(53 - 1) = a₁ + 208
a₂₀₀ = a₁ + 4(200 - 1) = a₁ + 796
7 over 4x-3 you just flip the fraction to get the inverse
