A floor of a room is in the shape of square. It is to be covered with rectangular tiles that each have an area of 192 square inches.If the length of the floor is 14 feet, how many tiles are needed to cover the floor?

Answers

Answer 1

Answer: find area of room
aera=legnth wtimes width
in a square, legnth=width
aera=legnth^2
legnth=14 feet
convert o inches
14*12=168 inches
area=168^2=28224 square inches

how many tiles will cover all of floor?
aka
how many 192 in^2 is at least 28224 (at least, because we need to cover the whole floor without gaps)
192x>28224
divide both sides by 192
x>147

147 is the number of tiles we need

Answer 2

Answer: the answer is 147 first convert 14 ft. into inches 14×12=168 168×168=28225 28225÷192=147

A large multiplex movie house has many theaters. The largest theater has 44 rows. There are 20 seats in the first row. Each row has four seats more than the previous row. How many total seats are there in this theater?

Answers

Final answer:

The total number of seats in this movie theater is 4224. This is calculated using the sum of an arithmetic series formula.

Explanation:

The question describes an arithmetic sequence where each row in the theater has four more seats than the previous row. The first row has 20 seats and the last row (44th row) has $20 + 4*(44-1) = 172$ seats. The total number of seats in this theater is therefore the sum of an arithmetic series formula, which is given by:

$S = n/2 * (a + l)$

Where:

S is the sum of the sequence
n is the number of terms
a is the first term
l is the last term

So for the number of seats, we have:

$S = 44/2 * (20 + 172) = 22 * 192 = 4224.$

So, the total number of seats in the theater is 4224.
