Answer:
61.6 dollars
Step-by-step explanation:
So, lets go over what we know:
The shows orginally cost 88 dollars.
They are 30% less than that.
This basically means that the shoes will cost 70 percent of their orginal price.
We can basically find the new cost by multiplying the 88 dollars by the 70 percent.
Or, multiplying 88 by 0.7, which is the decimal form of 70%.
88*0.7=61.6
How did I get this?
Multiply 80 by 0.7:
7*8=56
We have 0.7 so it = 5.6
However, it's tens place is 80, not 8, so it will be = 56
It is the same thing in the ones place, however it is 8 not 80, so it will be 0.7*8
= 5.6
56+5.6=61.6
So 61.6 is our answer.
Hope this helps!
Answer:
50.24
Step-by-step explanation:
The formula for the area using diameter is A=1/4πd^2. So just plug the 8 into the formula, A=1/4π8^2, and solve. The answer will come out to be 50.27 which is the closest to 50.24.
Since this is an arithmetic sequence, the first thing to note is that n is both a variable within the definition of the sequence, and it also is the index value too. As an index value, it has to be an integer as there is no such thing as a fractional index. Next, all indexes start from the number 0, because the 0th term is the initial value of the sequence. Therefore, n must also start with 0. All subsequent terms in the sequence are then terms with higher index values, so n will always be greater than or equal to 0. A quick check on the equation will also show that there is no other limiting factor on n. Thus, the correct answer is "All integers where n<span>≥</span>0".
