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)
Simplifying this expression, we divide 1.36 by 1.6 and subtract the exponents:
Width = 8.5×10^4 ft
Therefore, the width of the park is 8.5×10^4 ft.
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)
Simplifying this expression, we divide 1.36 by 1.6 and subtract the exponents:
Width = 8.5×10^4 ft
Therefore, the width of the park is 8.5×10^4 ft.

To divide 3.3×10^4 by 5.5×10^7, we can divide the numbers in decimal form and subtract the exponents:
Dividing 3.3 by 5.5 gives us 0.6.
Subtracting the exponents of 10^4 and 10^7, we get 10^(-3):
So, the result is 0.6 × 10^(-3) or 6 × 10^(-4) in scientific notation.
Therefore, 3.3×10^4 divided by 5.5×10^7 is 6×10^(-4).
Dividing 3.3 by 5.5 gives us 0.6.
Subtracting the exponents of 10^4 and 10^7, we get 10^(-3):
So, the result is 0.6 × 10^(-3) or 6 × 10^(-4) in scientific notation.
Therefore, 3.3×10^4 divided by 5.5×10^7 is 6×10^(-4).

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 lunches = Grant amount / Cost per lunch
Number of lunches = (1.925×10^6 dollars) / ($2.75)
To divide the numbers in decimal form, we divide 1.925 by 2.75:
Number of lunches = 0.7
Now, let's find the exponent of 10. Since there was a division, we need to subtract the exponents:
Exponent of 10 = 10^6 / 10^2 = 10^4
So, the result is 0.7×10^4 or 7×10^3 in scientific notation.
Therefore, the grant can provide 7×10^3 senior lunches.
Grant amount = 1.925×10^6 dollars
Cost per lunch = $2.75
Number of lunches = Grant amount / Cost per lunch
Number of lunches = (1.925×10^6 dollars) / ($2.75)
To divide the numbers in decimal form, we divide 1.925 by 2.75:
Number of lunches = 0.7
Now, let's find the exponent of 10. Since there was a division, we need to subtract the exponents:
Exponent of 10 = 10^6 / 10^2 = 10^4
So, the result is 0.7×10^4 or 7×10^3 in scientific notation.
Therefore, the grant can provide 7×10^3 senior lunches.
