A home has a living room that is 14 ft. wide, 22 ft. long, and a height of 9ft. Bob needs to paint

aleksandrvk [35]

Answer:

Step-by-step explanation:

Let's find the volume of the room in ft³ and that will give

14×22×9=2772ft³

There are deductions. Hence we subtract them from this value

3×5=15, but there are two, hence 15×2=30ft²

And 4×7=28ft²

Hence 2772-(30+28)=2714

Dividing this value by 320 gives

8.4(to 2s.f)

Answer:

$\frac{64}{49}$

Step-by-step explanation:

As we can see the given expression as three complex parts and all are being multiplied.

Lets simplify each part separately and then multiply all of them in the end

Part1

$(\frac{8.4.2}{8.7})^{2}$

Cancelling 8 in numerator with 8 in denominator

$(\frac{4.2}{7})^{2}$

$(\frac{8}{7})^{2}$

$\frac{64}{49}$

Part2

$(\frac{8^{0} }{7^{-3} })^{3}$

simpliying

$(\frac{1}{7^{-3} })^{3}$

$({7^{3} })^{3}$

$7^{9}$

Part3

Third part is $7^{-9}$ , and it does not need to be further simplified

Now multiplying all the three parts

$\frac{64}{49}.7^{9}.7^{-9}$

$\frac{64}{49}.7^{9-9}$

$\frac{64}{49}.7^{0}$

$\frac{64}{49}.1$

$\frac{64}{49}$

So our final answer is $\frac{64}{49}$
