Answer:

Zero does not have a positive or negative value. However, zero is considered a whole number, which in turn makes it an integer, but not necessarily a natural number

Question 1
Alexxx [7]

Answer:

Water needed for pool = 486 cubic feet

Plastic liner required for the pool = 298.3 feet

Step-by-step explanation:

Top view of the pool is a composite figure, having one rectangle and a trapezoid.

1). Water needed for the pool = volume of the pool

Volume of the pool = Area of the base × Depth

                               = (Area of the rectangle + Area of the trapezoid)× depth  

Area of the trapezoid = \frac{1}{2}(b_{1}+b_{2})\times h

                                    = \frac{1}{2}(11+9)\times (12-1.5)

                                    = 105 ft²

Area of the rectangle = Length × width

                                    = 11 × 1.5

                                    = 16.5 ft²

Now, volume of the pool = (105 + 16.5) × 4

                                          = 121.5 × 4

                                          = 486 cubic feet

b). Liner required = surface area of the pool excluding top

                             = Surface area of the walls + Area of the pool base

                             = (Perimeter of the pool) × depth + area of the base

                             = (12 + 11 + 1.5 + 10.7 + 9)×4 + 121.5

                             = 176.8 + 121.5

                             = 298.3 square feet

Therefore, amount of water required = 486 cubic feet

liner needed = 298.3 square feet

Anthony grew 64 plants with 32 seed packets.How many seed packets does Anthony need to have a total of 90 plants in his backyard
adelina 88 [10]
Let the total seed packets needed Anthony to have 90 plants be x.

then,
64:32 :: 90:x
2:1 :: 90:x
90 = 2x
x = 45 seed packets.

________________________

64 plants = 32 seed packets.
1 plant = \frac{32}{64} = \frac{1}{2} seed packets.

90 plants = \frac{1}{2} \times 90 = 45 seed packets.

Anthony need 45 seed packets to have 90 plants.

!! Hope It Helps !!
