A marching band is performing in a rectangular arrangement, with a width of $w$ people. The length consists of seven less people

Norma-Jean [14]

Answer:

There are 120 people in the marching band.

Step-by-step explanation:

Let no. of people in the band be x.

In the first rectangular arrangement,

Width of rectangle ( $w_{1}$ ) = w people.

Length of rectangle ( $l_{1}$ ) = (w-7) people

Therefore,

no. of people in the band(x) = Area of the rectangle = Product of width and Length

x = width $\times$ length

x = $w\times (w-7)$ (equation 1);

In the second rectangular arrangement,

Width of rectangle ( $w_{2}$ ) = (w-3) people.

Length of rectangle ( $l_{2}$ ) = (w-5) people

Therefore,

no. of people in the band(x) = Area of the rectangle = Product of width and Length

x = width $\times$ length

x = $(w-3)\times(w-5)$ (equation 2);

Therefore, from equation 1 and equation 2 , we get,

$w\times(w-7)=(w-3)\times(w-5)$

$w^{2}-7w=w^{2} - 8w + 15$

Therefore,

w = 15 (equation 3)

From equation 1 and equation 3, we get

x = $15\times(15-7)$

x = 120.

Therefore,

no. of people in the marching band = 120 people

The typical full-time employee in a particular hotel works a 40-hour week. Last month, the hotel's 80 employees worked a total o

Mila [183]

Answer: There are 25 FTEs.

Step-by-step explanation:

Since we have given that

Number of hour week for full time employee = 40 hours

In a month we know that

Number of weeks = 4

Total number of hours in a month would be

$40\times 4\\\\=160\ hours$

If in last month, the hotel's 80 employees worked a total of 4000 hours,

So, Full time equivalent workers were employed by the hotel last month would be

$\dfrac{4000}{160}\\\\=25$

Hence, there are 25 FTEs.
