Answer:
189 tickets sold on Saturday.
Step-by-step explanation:
Your ratio of 8:1 is children's tickets to adult tickets.
There are 8 times as many children tickets sold as adult tickets.
Let c = # children's tickets
Let a = # adult tickets
8a = a + 147
subtract a from both sides
7a = 147
divide on both sides by 7
a = 147/7
find number of adult tickets
a = 21 adult tickets
multiply the number of adult tickets by 8 to find children's tickets 21*8=168
168+21=189 tickets sold on Saturday.
Answer:
Step-by-step explanation:
Let the integer be 6 for even and 7 for odd (say)
For 6, we divide by 2, now get 3. Now we multiply by 3 and add 1 to get 10. Now since 10 is even divide by 5, now multiply by 3 and add 1 to get 16. Now divide by 2 again by 2 again by 2 again by 2 till we get rid of even numbers.
The result is 1, so multiply by 3 and add 1 we get 4 now divide 2 times by 2 to get 1, thus this result now again repeats after 2 times.
Say if we select off number 3, multiply by 3 and add 1 to get 10 now divide by 5, now repeat the same process as above for 5 until we get 1 and it gets repeated every third time.
Thus whether odd or even after some processes, we get 1 and the process again and again returns to 1.
Answer:

Explanation:
Since the <em>bases</em> must not be painted, their areas are <em>not included</em> in the calculation.
The <em>surface</em> to paint, of each pillar, is equal to the lateral area of a<em> cylinder </em>with he dimensions given.
The formula for the laeral area of a cylinder is:

Substitute including the conversion factor to convert inches to feet:

<span>88 stamps -------------------- > $15.56
A------------------------------>number of </span>stamps ------------ ><span>25 cent
B----------------------------- > </span>number of stamps ------------ >2 cent
A+B=88------------------ > A=88-B
0.25A+.02B=15.56
resolving
0.25(88-B)+0.02B=15.56
22-0.25B+0.02B=15.56
-0.23B=-6.44----------------------- > B=28 stamps of 2 cent
A=88-B-- >88-28=60------------- > A=60 stamps of 25 cent
