Let b the book :
it is proportion
6/11=b/13543
b=(6/11)(13543)
b=7307 books
73707-3500 = 3887 book is remaining.
Answer:
V = 84.78 ft^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = 3.14 ( 3)^2 (3)
V = 3.14 *9(3)
V = 84.78 ft^2
The answer is (a) 2x^4 y^8
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Let r and s represent the number of times Caleb can ride the roller coaster and watch a show, respectively. The time Caleb needs to allow for each roller coaster ride is (wait time) + (ride time) = (30 +5) min = 35 min. Then we can write the equations
r - s = 3
35r +25s ≤ 345
Adding 25 times the first equation to the second, we get
25(r -s) +(35r +25s) ≤ 25(3) +(345)
60r ≤ 420 . . . . . . collect terms
r ≤ 7 . . . . . . . . . . . divide by 60
Caleb can ride a maximum of 7 roller coasters and watch 4 shows in 345 minutes.

The problem can obviously be worked using two equations instead of one equation and an inequality. It isn't clear until the final answer that the number of minutes comes out exactly the amount needed, which is why we chose an inequality.
