Sandra bought 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each side of t

BARSIC [14]

Answer:
length of each side of the room is 2√30 which is approximately 10.9545 ft

Explanation:
The area of the square can be computed as follows:
Area = l²
where l is the length of the side

We are given that:
area = 120 ft²

Substitute with the area in the above equation and solve for l as follows:
area = l²
120 = l²
l = √120
l = 2√30 ft
This is approximately equal to 10.9545 ft

Hope this helps :)

A central angle measuring 120° intercepts an arc in a circle whose radius is 3.

Kisachek [45]

Answer:

6.28

Step-by-step explanation:

The length of arc which subtends an angle $\alpha$ at the center of a circle is given by $\alpha r$ where r is the radius of circle.

______________________________

given

the central angle of arc is 120°

$\pi = 180\\120 = (\pi /180)* 120\\120 = 2/3\pi$

we will use value of $\pi$ as 3.14

r = 3

Length of this arc is

$2/3( \pi *3) = 2\pi \\=2*3.14 = 6.28$

The length of the arc to the nearest hundredth of unit is 6.28

Help quickly plz!!

<h2>Explanation:</h2><h2 /><h3><u>PART 1. Using an algorithm:</u></h3>

<u>First expression:</u>

$3 \times \frac{3}{4}$

Step 1: Multiply numerators and denominators.

$3 \times \frac{3}{4}=\frac{9}{4}$

<u>Second expression:</u>

$\frac{1}{4} \times \frac{2}{3}=\frac{2}{12}$

Step 1: Multiply numerators and denominators.

$3 \times \frac{3}{4}=\frac{9}{4}$

<u>Third expression:</u>

$1\frac{1}{3} \times 2$

Step 1: Convert mixed fraction into improper fraction:

$1\frac{1}{3} \\ \\ \\ Add \ whole \ and \ fractional \ part: \\ \\ 1+\frac{1}{3}=\frac{4}{3}$

Step 2: Replace the improper form into the expression

$\frac{4}{3}\times 2$

Step 2: Multiply numerators and denominators.

$\frac{4}{3}\times 2=\frac{8}{3}$

<h3><u>PART 2. Using diagram:</u></h3><h3 />

The diagram is shown below. Basically the steps we follow are the same as if it were using algorithms.
