Answer:
768 tiles would be required to tile the floor.
Step-by-step explanation:
Let's first calculate the number of square meters that the rectangular floor represents, by using the formula for the area of a rectangle (length x width):
Floor area = 8 m x 6 m = 48
Next, let's convert the side of the square tiles into meters in order to keep the same units in both (floor area an tile area):
25 cm = 0.25 m
Then the are of a square tile can be obtained by the formula 0.25 m x 0.25 m = 0.0625
Now to find the number of tiles needed, we perform the division of the total floor area to be covered divided by the area covered by a single tile:
Number of tiles needed: 48 / 0.0625 = 768 tiles
Answer:
y=5x+50
Step-by-step explanation:
Y= how much money in your account.
you use the formula y=mx+b to show a steady slope.
B is the Y-intercept or where your data starts.
In this case it would be $50.
You then add or deposit 5 dollars each week.
X=# of weeks.
Y = 5x + 50
You have $50, and for x amount of weeks you deposit $5

Answer:
13.09 in²
Step-by-step explanation:
<u>Formula to find the Area of Segment:</u>
- <em>A= (θ × π/360° − sin(θ)/2) × r², where θ = arc in degrees, r = radius of circle</em>
<em>We need to find the radius of the circle for our calculation of area of the segment.</em>
<em>Refer to picture.</em>
<u>The right triangle ΔOBC has:</u>
- BC= 1/2 of chord AB = 8 in/2 = 4 in
- ∠COB = 1/2 θ= 1/2*120° = 60°
<u>Since ΔOBC is 30-60-90 triangle:</u>
<u>Then the area of segment:</u>
- A= (θ × π/360° − sin(θ)/2) × r² =
- (120° × π/360° − sin(120°)/2) × (8√3/3)² =
- (3.14/3 - √3/4)× 64/3 =
- 13.09 in²
<u>Answer:</u> 13.09 in²
