x^2 + y^2 - 4y = 21

x^2 + y^2 - 4y + 4 = 25

x^2 + (y - 2)^2 = 5^2

Write 4 feet to 15 inches as a ratio. Compare in inches. Write the ratio in lowest terms.

Alja [10]

1 ft = 12 inches....so 4 ft = (4 * 12) = 48 inches

ratio is : 48 to 15...or 48/15 or 48:15......which reduces to 16/5 in lowest terms

The net of a square pyramid is shown

Wewaii [24]

Answer:

Option (D)

Step-by-step explanation:

Surface area of a square pyramid is determined from the formula,

Surface area = Area of the square base + 4(Area of one lateral triangular side)

Area of the base = (Side)²

= 8²

= 64 cm²

Area of one lateral triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(8)(8)$

= 32 cm²

Therefore, surface area of the square pyramid = 64 + 4(32)

= 64 + 128

= 192 cm²

Therefore, Option (D) will be the correct option.
