Answer:
Step-by-step explanation:
the area of the circle A= 3.14*r^2
diameter is 6, radius is 6/2=3
it is choice 2
A=3.14*3^2
Let's just work through this one using logic. Here's what we know:* it costs $7 for first 3 pages* it costs $3 for each additional page* $100 total was spent$100 - $7 leaves us with $93 remaining. Divide that $93 by $3 to get 31 pages. Add that 31 pages to the initial 3 you spent $7 on and get a total of 34 pages for $100.
Answer:
<h2>$33.46</h2>
Step-by-step explanation:
To find the cost after a 6% tax and a 15% tip, we need to multiply the amount by these two percents. Add the percents together to make the math easier.
$27.65 x 0.21 = $5.81
Now, add that number to the original cost to get the answer
$27.65 + $5.81 = $33.46
The cost of a $27.65 bill after a 6% and 15% tip is $33.46
I'm always happy to help :)

chairs in the nth row
an = 4 + 23*5 = 119
and the sum is
sn = (4 + 119) * 24/2 = 1476</span>
