Answer:
$43.20
Step-by-step explanation:
We use the formula for the final cost of the item:
where r is the percent tax rate in decimal form (8% therefore translates as 0.08 for our case)
Therefore the final cost of the item is $43.20
Answer:
-2 and 21/50
Step-by-step explanation:
PEMDAS says that paranthases go first, so we solve 2 and 1/5 minus 33/12. 2 and 1/5 simplifies to the improper fraction, 11/5. Then we find a common denominater between 11/5 and 33/12 to get 60. 11/5=132/60, and 33/12=165/60. (132/60)-(165/60)=-33/60. Then we multipl that by 4 and 2/5, which can simplify to the improper fraction, 22/5. (22/5)*(-33/60) is -726/300, and simplifies to -2 and 21/50. Hope this helps!
Answer:
K=-2.5
Step-by-step explanation:
because the line is in the middle of 2 and 3 and is below which means that it is negative
This is an arithmetic sequence because each term is 9 more than the previous term, called the common difference. The equation for an arithmetic sequence is:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number...
In this case a=9 and d=9 so
a(n)=9+9(n-1)
a(n)=9+9n-9
a(n)=9n
So for any term n, a(n)=9n
...
a(16)=9*16=144
