Answer:
30
Step-by-step explanation:
6 choices for the 1st, then 5 choices for the 2nd, so: 6*5=30
or nPk=n!/(n-k)! with n=6 and k=2
Put it simply each letter can be combined with 5 diffrent letters and with 6 total letters 6x5=30
Since those lines are parallel, we know that A + B = 180°
So, we have:
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 180 - 130
10x = 50
x = 5
B = 2x + 56
B = 10+56=66
(To check:
A = 8x + 74
A = 40+74=114
114+66=180)
<h3>Answer:
$186.03</h3>
===================================================
Explanation:
It costs $91.50 for the first 200 copies.
Roger needs 200 more copies to get to 400 total.
He's charged $42 per 100 copies at this point, so he is charged 42*2 = 84 extra dollars to do those extra 200 copies.
Before tax, his total is 91.50+84 = 175.50 dollars.
The sales tax will increase the bill by 6%
To increase by 6%, we use the multiplier 1.06
1.06*175.50 = 186.03
Or you can follow the steps shown in the next section.
-----------------
6% of 175.50 = 0.06*175.50 = 10.53
The sales tax is $10.53
175.50 + 10.53 = 186.03
-----------------
Whichever method you use, you should end up with an after-tax cost of $186.03
so... notice the example there, with 8
so.. you tell us, what is the relationship then?
