Assuming the figure has identifiable bases and sides, the total surface area is the sum of the areas of those:

... B. Base area + lateral area

The surface area of any object is the sum of all areas on the object itself, and thus it cannot be D. This would include both the base area and the lateral areas. And thus the correct answer would be B.

How many 4' x 8' sheets of plywood are required to cover a floor that is 9 m by 16 m?

Xelga [282]

Assuming no border or waste, 9m by 16 m translates to 29.52' x 52.49'.
use 32/8=4 sheets of plywood to cover the width on the 8' side.
For the length, use 52/4=13 pieces on the 4' side.
This gives a total of 4*13=52 sheets.
The extra 0.49' x 29.52 can be covered using the extra from the last four sheets for the width.

Check:
Area to be covered: 29.52*52.49=1550 sq. ft.
Area of plywood supplied = 52*4'x8'= 1664 sq. ft, > 1550 sq.ft.

Techwiz electronics makes a profit of $35 for each MP3 player sold and $18 for each DVD player sold. Last week, Techwiz sold a c

kicyunya [14]

The combined total profit is (17x + 2502) dollars

Solution:

Profit for each Mp3 player = $ 35

Profit for each DVD player = $ 18

Let x be the number of MP3 players sold last week

Number of MP3 players = x

Last week, Techwiz sold a combined total of 139 MPS and DVD players

Total number of mp3 and dvd sold = 139

Number of DVD player = 139 - x

Write an expression for the combined total profit (in dollars) Techwiz made from MP3 and DVD players last week.

Combined total profit = Number of MP3 players x Profit for each Mp3 player + Number of DVD player x Profit for each DVD player

$combined\ total\ profit = x \times 35 + (139-x) \times 18\\\\combined\ total\ profit = 35x + 2502-18x\\\\combined\ total\ profit = 17x + 2502$

Thus the combined total profit is (17x + 2502) dollars
