Bill wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 28 feet and its width is 25 feet. Suppose each pack of seed covers 14 square feet. How many packs of seed will he need to cover the backyard?
The area of the backyard is the product of its length and width: 28 feet * 25 feet = <<28*25=700>>700 square feet.
Thus, Bill will need 700 square feet / 14 square feet/pack = <<700/14=50>>50 packs of seed. Answer: \boxed{50}.
what is 30%of 82
To find 30% of 82, you can multiply 82 by 0.30, which represents 30% as a decimal.
30% = 30/100 = 0.30
Therefore, 30% of 82 is 82 * 0.30 = 24.6.
So, 30% of 82 is equal to 24.6. Answer: \boxed{24.6}.
To find out how many packs of seed Bill will need to cover his backyard, we need to calculate the total area of the backyard and then divide it by the area covered by each pack of seed.
Step 1: Calculate the area of the backyard.
The area of a rectangle can be found by multiplying its length by its width.
Area = Length x Width
Length = 28 feet
Width = 25 feet
Area of the backyard = 28 feet x 25 feet
Step 2: Calculate the total area covered by each pack of seed.
Each pack of seed covers 14 square feet.
Step 3: Divide the total area of the backyard by the area covered by each pack of seed.
Number of packs of seed needed = Area of the backyard / Area covered by each pack of seed
Let's do the calculations:
Area of the backyard = 28 feet x 25 feet
Area of the backyard = 700 square feet
Number of packs of seed needed = 700 square feet / 14 square feet
Number of packs of seed needed = 50 packs
Therefore, Bill will need 50 packs of seed to cover his backyard.
