A brand of clay brick tiles has the dimensions 3 5 8 by 7 5 8 by 1 2 inch. These thin bricks are commonly used for floors. Estim

raketka [301]

Answer: The cost to tile the floor is $318.24.

Step-by-step explanation:

Since we have given that

Dimensions of floor is 12 by 17 foot.

So, Area of floor would be

$12\times 17\\\\=204\ sq.\ foot$

As we know that 1 foot = 12 inch

So, Area of floor would be

$204\times (12)^2\\\\=204\times 144\\\\=29376\ sq.\ foot$

Dimension of brick tiles is given by

$3\dfrac{5}{8}\ by\ 7\dfrac{5}{8}\ by\ \dfrac{1}{2}$

So, Area of brick tiles is given by

$2(lb+bh+lh)\\\\=2(\dfrac{29}{8}\times \dfrac{61}{8}+\dfrac{61}{8}\times \dfrac{1}{2}+\dfrac{29}{8}\times \dfrac{1}{2})\\\\=2(\dfrac{1769}{64}+\dfrac{61}{16}+\dfrac{29}{16})\\\\=2\times \dfrac{1769+244+116}{64}\\\\=\dfrac{2129}{32}$

So, Number of clay brick would be

$29376\div \dfrac{2129}{32}\\\\=29376\times \dfrac{32}{2129}\\\\=\dfrac{29376\times 32}{2129}\\\\=441.53\\\\\approx 442$

cost of each clay brick = $0.72

So, Total cost of flooring would be

$442\times 0.72\\\\=\$318.24$

Hence, The cost to tile the floor is $318.24.

Find the difference!!!!!!!!!!!!!!!!!!11

pav-90 [236]

Answer:

-4

Step-by-step explanation:

-10 - (-6)

Remove the brackets:

-10 - - 6

Remember that all negative and negative values are always positive because they are the same; if they are different, for instance, a positive value and a negative value, then that value will be a negative value.

Continue solving:

-10 - - 6

- and - are positive values

- 10 + 6

= - 4

Therefore the answer is 4

Which value of c would make the following express completely factored? 8x+cy

Artist 52 [7]

The answer is B, 7.

$\sf 8x+2y$

We can factor a 2 out of this: $\sf 2(4x+y)$

$\boxed{\sf 8x+7y}$

We can't factor anything.

$\sf 8x+12y$

We can factor a 4 out of this: $\sf 4(2x+3y)$

$\sf 8x+16y$

We can factor an 8 out of this: $\sf 8(x+2y)$

So your answer is B, 7.
