hope that helps ;)
To find the width of the park, we need to divide the area by the length.
Area = 1.36×10^8 ft^2
Length = 1.6×10^4 ft
Width = Area / Length
Width = 1.36×10^8 ft^2 ÷ 1.6×10^4 ft
To divide the numbers in scientific notation, we subtract the exponents of 10 and divide the coefficients:
Width = (1.36 ÷ 1.6) × 10^(8-4)
Width = 0.85 × 10^4
Therefore, the width of the park is 8.5×10^3 ft or 8,500 ft.

To divide 3.3×10^4 by 5.5×10^7, we can divide their coefficients and subtract their exponents of 10:
(3.3×10^4) ÷ (5.5×10^7) = (3.3 ÷ 5.5) × 10^(4-7) = 0.6 × 10^(-3)
Therefore, the answer is 6×10^(-3), which means 6 times 10 to the negative 3 power.
A city lunch program for seniors received a grant of 1.925×106 dollars. Divide that figure by the cost of $2.75 per lunch to find out how many senior lunches the grant can provide. Write the answer in scientific notation.(1 point)

To find out how many senior lunches the grant can provide, we need to divide the grant amount by the cost per lunch.
Grant amount = 1.925×10^6 dollars
Cost per lunch = $2.75
Number of senior lunches = Grant amount / Cost per lunch
Number of senior lunches = 1.925×10^6 dollars / $2.75
To divide the grant amount by the cost per lunch, we divide the coefficients and subtract the exponents of 10:
Number of senior lunches = (1.925 ÷ 2.75) × 10^(6-0) = 0.7 × 10^6
Therefore, the grant can provide 0.7×10^6 senior lunches.

To find out how much perfume will be in each container, we need to divide the total amount of perfume by the number of containers.
Amount of perfume = 10.5 gallons
Number of containers = 3.5×10^2
Amount of perfume per container = Amount of perfume / Number of containers
Amount of perfume per container = 10.5 gallons / 3.5×10^2
To divide the amount of perfume by the number of containers, we divide the coefficients and subtract the exponents of 10:
Amount of perfume per container = (10.5 ÷ 3.5) × 10^(0-2) = 3 × 10^(-2)
Therefore, each container will have 3×10^(-2) gallons of perfume.
