A dance studio is purchasing tutus for an annual performance. The table represents the number of tutus available for different prices. The director wants to place an order for the LEAST EXPENSIVE DEAL and the MOST EXPENSIVE DEAL. Calculate the average unit price for each tutu the director orders. A) $25 B) $28 C) $30 D) $33

Answers

Answer:

30$ C

Step-by-step explanation:

Final answer:

To calculate the average unit price of the tutus, you would normally divide the total cost by the quantity. This would give you the cost per tutu. However, without information on quantities, we can't compute averages. The director should examine the table for the deals with the lowest and highest average unit costs.

Explanation:

From the given problem, it seems more information is needed. Normally, a table would offer pairs of information with the cost per tutu at different quantities. If we had a total cost and a quantity, we could calculate an average by dividing the total cost by the quantity. For example, if the director orders 10 tutus at a total cost of $250, the average unit price for each tutu would be $250/10 = $25 per tutu. Similarly, if 10 tutus cost $330, we would calculate $330/10 to get $33 per tutu. However, without the quantities, we can't make these calculations. The director should carefully examine the table listing unit prices and quantities and choose the deal with the lowest average unit cost for the least expensive deal and the deal with the highest average unit cost for the most expensive deal.

Two cones are similar. The volume of the larger cone is 27 cm' and the volume of the smallercone is 8 cm". The height of the smaller cone is 2 cm.
What is the height of the larger cone?

Answers

Answer:

Step-by-step explanation:

Let V and v be volumes of two similar cones.

so R/r=H/h

V=1/3π R²H

v=1/3πr²h

$(V)/(v) =(\pi R^2H )/(\pi r^2h ) =((R)/(r) )^2((H)/(h) )=((H)/(h) )^3\n(27)/(8) =((H)/(2) )^3\n(3^3)/(2^3) =((H)/(2) )^3\n((3)/(2) )^3=((H)/(2) )^3\n(H)/(2) =(3)/(2) \nH=(3)/(2) * 2=3$
