Recall that division by zero is undefined. That is, we cannot have zero in the denominator of a fraction. Therefore, while we could write 0 as 0 / 1, we could not "flip" this fraction since that would cause division by zero. Zero has no reciprocal.

The reciprocal of 0 is undefined. 0 is a whole number and as a fraction is 0/1

the reciprocal of a fraction is the flip of the fraction. So the reciprocal of 0/1 is 1/0.

This is called division of zero and the answer is undefined.

Christina wants to compute the cost of tiling the floor in her bathroom. The floor measures 7 feet 6 inches by 8 feet 10 inches.
ArbitrLikvidat [17]

Answer:

Two boxes will cost \$35.95\cdot 2=\$71.9. The cost of one tile is approximately \dfrac{\$71.9}{67}\approx \$1.08.

Step-by-step explanation:

Note that 1 ft = 12 in, then

7\ ft\ 6\ in=7\cdot 12+6\ in =90\ in,\\ \\8\ ft\ 10\ in=8\cdot 12+10\ in=106\ in.

The area of the floor is

90\cdot 106=9540\ in^2.

Now

1\ ft^2=144\ in^2,

then

144 sq. in - 1 tile,

9540 sq. in - x tiles.

Mathematically,

\dfrac{144}{9540}=\dfrac{1}{x},\\ \\x=\dfrac{9540}{144}=66.25

tiles is needed to cover the floor (67 full tiles).

Each box of tiles contains 45 tiles, so Cristina has to buy 2 boxes. These two boxes will cost \$35.95\cdot 2=\$71.9. The cost of one tile is approximately \dfrac{\$71.9}{67}\approx \$1.08.

Given that f(x) = 2x + 1 and g(x) = the quantity of 3x minus 1, divided by 2 , solve for g(f(3)).
Andrew [12]

Answer:

10

Step-by-step explanation:

Firstly, find the value of f(3)

⇒ f(3) = 2(3) + 1   [sub in 3]

⇒ f(3) = 7   [multiply by 2 and add 1]

Now, find g(f(3))

⇒ g(f(3)) = \frac{3(7) - 1}{2}   [sub in 7]

⇒ g(f(3)) = \frac{20}{2}   [multiply by 3 and subtract 1]

⇒ g(f(3)) = 10   [divide by 2]
