A rectangular park has an area of 1.36 x 10^8 ft^2
. The length of the park is 1.6 x 10^4 ft. Divide the area by the length to
find the width of the park. (1 point)
• 8.5 × 10^4 ft.
• 8.5 × 10^3 ft.
• 8.5 × 10^2 ft.
• 8.5 x 10^5 ft.
To find the width of the park, we need to divide the area by the length.
Area = 1.36 x 10^8 ft^2
Length = 1.6 x 10^4 ft
Width = Area / Length
Width = (1.36 x 10^8 ft^2) / (1.6 x 10^4 ft)
We can simplify this expression by dividing the coefficients and subtracting the exponents:
Width = 1.36 / 1.6 x 10^(8-4) ft
Width = 0.85 x 10^4 ft
0.85 x 10^4 ft can be written in scientific notation as 8.5 x 10^3 ft.
Therefore, the width of the park is 8.5 x 10^3 ft, which corresponds to the option: 8.5 × 10^3 ft.
To find the width of the park, we need to divide the area by the length.
Given:
Area = 1.36 x 10^8 ft^2
Length = 1.6 x 10^4 ft
To find the width, we divide the area by the length:
Width = Area / Length
Width = (1.36 x 10^8 ft^2) / (1.6 x 10^4 ft)
To divide the numbers in scientific notation, we subtract the exponents:
Width = (1.36 / 1.6) x (10^8 / 10^4) ft
Width = 0.85 x 10^(8-4) ft
Width = 0.85 x 10^4 ft
Writing it in scientific notation:
Width = 8.5 x 10^3 ft
So, the width of the park is 8.5 x 10^3 ft. Therefore, the correct option is:
• 8.5 × 10^3 ft.
To find the width of the park, we need to divide the area of the park by its length.
Area = 1.36 x 10^8 ft^2
Length = 1.6 x 10^4 ft
To divide these values, we can use the formula:
Width = Area / Length
Substituting the given values, we have:
Width = (1.36 x 10^8 ft^2) / (1.6 x 10^4 ft)
To divide numbers written in scientific notation, we can divide the coefficients (1.36 / 1.6) and subtract the exponents (10^8 / 10^4).
Let's calculate it step by step:
Coefficient: 1.36 / 1.6 = 0.85
Exponent: 10^8 / 10^4 = 10^(8 - 4) = 10^4
Therefore, Width = 0.85 x 10^4 ft
In standard form, this can be written as:
Width = 8.5 x 10^3 ft
So the correct answer is: 8.5 × 10^3 ft.
