Answer:
Step-by-step explanation:
The given series is
The first term is
The last term is
To find the number of terms in the sequence, solve,
The sum of the first i-terms of an arithmetic sequence is:
We substitute the values to get;
There are 540 fuses in total and the original price of the internet is $55.91
<h3>
How to work with percentages?</h3>
a) We know that 5% of the fuses are faulty, and there are 27 faulty fusses, then we can write:
5% = 27
100% = x
We want to find x, to do that, we can write:
x = 27*(100%/5%) = 27*20 = 540
There are 540 fuses in total.
b) Now we know that the original price is P, and when we decrease it by 7%, then new price is $52.00
Then we can write:
$52.00 = P*(1 - 7%/100%)
$52.00 = P*(0.93)
$52.00/0.93 = P = $55.91
The original price is $55.91

If the smaller number is n, then the next odd integer can be expressed as n+2. The sum of these is
n + n + 2
or
2n + 2
Answer:
the point of interception is (8,3)
Step-by-step explanation:
The x variable represents the number of three point shots made and the y variable represents the number of two point shots made. Since the lines intersect at the point (8,3) we can say:
Nicole made 8 three point shots and 3 two point shots.
