(0,0) , (1,4) , ( 2,8) are the ordered pairs
Step-by-step explanation:
because because that would be subtracting positive 10 by -10. not adding -10 + -10 which would be 20
Both base and height of the sail is 40 1/2 feet.
A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.
A = 1/2 bh
Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft

Answer:
360 cents or $ 3.6
Step-by-step explanation:
Let x be the original cost ( in cents ) of each note book,
After reducing the price by 30 cents,
New cost of each book = x - 30,
According to the question,
3x = 4(x-30) ( ∵ total cost = number of books × cost of each book ),
3x = 4x - 120
3x - 4x = -120
-x = -120
x = 120
Hence, the cost of three books = 3 × 120 = 360 cents or $ 3.6
