Answer:
the answer is 15
Step-by-step explanation:
Given data:
Volume V = 45 π and radius
r = 3 units The formula for the volume of the cylinder is V = B · H
Base of the cylinder is:
B = r² π = 3² π = 9 πFrom the formula V = B · H we get H:H = V / B = 45 π / 9 π = 5 units
H = 5 units
To find how many seats in the 80th row, you need to figure out the pattern from the 8th row to the 20th row.
To do this, you can create a table showing possibilities from the 8th to the 20th.
I started with 32 at the 8th and added 2 each time. This was only 56 by the 20th.
Then I added 3, and this got me to 68 by the 20th row.
Then you can work backwards to find how many seats in the 1st row. I got 11.
From here you can create an equation that you could use to solve for the 80th row.
11 + 3(r - 1), where r is the number of rows.
Substitute in 80 for r.
11 + 3(80 - 1)
11 + 237
248 seats
There are 248 seats in the 80th row.
Answer:
Christmas lights are price based shopping products
Step-by-step explanation:
From the question we understand that, Beth bought as many cheapest lights as possible. This means that she places value over quantity than quality.
The above is an illustration of price based shopping products where customers (in this case, Beth) see all products (in this case, Christmas lights) as similar products, irrespective of their different qualities (after all, they all light Christmas trees).
Because of this, the customer will opt for least expensive items, leaving the more expensive items.
