Answer:

She can paint <u>6 rooms</u>.

Step-by-step explanation:

Given:

Maya decided to paint some of the rooms in her hotel. She found out that a room required 3/2 cans of paint.

If Maya buys 9 cans of paint.

Now, to find the rooms she can paint.

So, we use unitary method to get the number of rooms:

If, $\frac{3}{2}$ cans of paint is needed to paint 1 room.

Then, 1 can of paint is needed to paint = $\frac{1}{\frac{3}{2}} =\frac{2}{3}$ room.

Thus, 9 cans of paint is needed to paint = $\frac{2}{3} \times 9$

$=\frac{18}{3} \\\\=6\ rooms.$

Therefore, she can paint 6 rooms.

Step-by-step explanation:

<u>Step 1: Define</u>

(4x² - 2x - 3) + (-3x² + x + 7)

<u>Step 2: Simplify</u>

Combine like terms (x²): x² - 2x - 3 + x + 7
Combine like terms (x): x² - x - 3 + 7

A rectangular garden is divided into two sections as shown.

azamat

Step-by-step explanation:

Pythagoras (for right-angled triangles) :

c² = a² + b²

c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.

c = diagonal = 10 ft

therefore, the width of the rectangle is 10/2 = 5 ft

10² = 5² + b²

100 = 25 + b²

b² = 75

b = length = sqrt(75) = 8.660254038... ft

A dartboard is divided into 20 sectors. Each sector is worth a point value from 1 to 20 and has shaded regions that double or

Nikitich [7]

The area of each sector is the amount of space on the sector

The area of the entire region is 6.89
The area of the double region is 0.75
The area of the triple region is 0.46

<h3>The area of the entire sector</h3>

The area of a sector is calculated as:

A = (1/2) × r^2θ

For the entire sector, we have:

θ = π/10

r = 6.625

So, we have:

A = (1/2) × 6.625^2 × π/10

Evaluate the product

A = 6.89

<h3>The area of the double region </h3>

For the double region, we have:

θ = π/10

r = 6.25

So, we have:

A = Complete sector - (1/2) × r^2θ

A = 6.89 - (1/2) × 6.25^2 × π/10

Evaluate the difference

A = 0.75

<h3>The area of the triple region </h3>

For the triple region, we have:

θ = π/10

R = 4.125

r = 3.75

So, we have:

A = (1/2) × R^2θ - (1/2) × r^2θ

A = (1/2) × 4.125^2 × π/10 - (1/2) × 3.75^2 × π/10

Evaluate the difference

A = 0.46

Hence, the area of the triple region is 0.46
