Q. A customer wants to re-carpet a living room andhallway. You charge $5.99 per square yard toremove old carpet and $4.50 per sq

Tanzania [10]

Living Room Area = 17.5 x 20 = 350 sq ft

Hall Area = 4 x 12 = 48 sq. ft.

Total area of carpeting: 340 + 48 = 398 sq. ft.

We need to convert total area in sq ft to sq yd. The conversion ratio is

1 sq ft = 0.11 sq yd

So, 398 sq ft would be:

398 * 0.11 = 44.22 sq yd.

Carpet removing rate is 5.99 per sq yd.

Removing rate would be:

44.22 * 5.99 = $264.88

Assuming you gotta install both carpet and pad,

Carpet + pad = 16.99 + 3 = 19.99 per sq yd.

You gotta buy for 44.22 sq yd.

So, it will cost (carpet):

44.22 * 19.99 = $883.96

Installing rate 4.50 per sq yrd, so to carpet 44.22 sq yd, would need:

4.50*44.22 = $198.99

Assuming carpet is provided by installation guys, total charge:

20 men decided to complete a work in 30 days. but after 6 days 8 men left now in how many day the work will be completed

Serga [27]

First, we convert it into a unit like this

20 workers × 30 days = 600 units work

After leaving the 5 workers, we have 35 days to complete the work.

In 35 days only 15 workers will do the work.

So the work completed in 35 days by 15 workers = 35 ×15 =525 units

Remaining unit = 600 -525 =75 units

This unit would do by 5 workers in (75/5) = 15 days.

So after 15 days, 5 workers should leave the job.

Answer:

Net Change in Geno's Field Position = 22 yards

Step-by-step explanation:

Assuming Geno initial position before change is 0

Geno Gained 4 yards three times = 4*3 = 12yards

Geno lose 1 yard twice = 1*(-2) = -2yards

Geno Gained 6 yards twice = 6*2 = 12yards

Net Change in Geno's Field Position = 12 + (-2) + 12 yards

= 22 yards

Draw a model of square root of 12 using perfect squares

Shkiper50 [21]

Answer:

The answer is " $\sqrt{12}$ is not a perfect square".

Step-by-step explanation:

12 is not a perfect square because it is the natural number, and no other natural number would square the number 12, that's why it is not a perfect square.

If we calculate the square root of $\sqrt{12}$ . so, it is will give $2\sqrt{3}$ that is not a perfect square root which can be described as follows:

$\Rightarrow \sqrt{12}= \sqrt{2\times 2\times 3}$

$= \sqrt{2^2\times 3}\\\\= 2\sqrt{3}\\\\$

$\bold{\sqrt{12}}$ is not a perfect square root.
