A rectangular park has an area of 1.36 × 10⁸ sq ft. The length of the park is 1.6 × 10⁴ ft. Divide the area by the length to find the width of the park. Choose the correct answer from below:
8.5 × 10²
8.5 × 10⁴
8.5 × 10⁵
8.5 × 10³
To find the width of the park, we need to divide the area of the park by its length.
Area of the park = 1.36 × 10⁸ sq ft
Length of the park = 1.6 × 10⁴ ft
Width = Area / Length = (1.36 × 10⁸ sq ft) / (1.6 × 10⁴ ft) = (1.36/1.6) × (10⁸/10⁴) = (0.85) × (10⁴) = 8.5 × 10⁴ ft
Therefore, the width of the park is 8.5 × 10⁴ ft.
The correct answer is 8.5 × 10⁴.
is it right
Apologies for the mistake in my previous response.
To find the width of the park, we need to divide the area of the park by its length.
Area of the park = 1.36 × 10⁸ sq ft
Length of the park = 1.6 × 10⁴ ft
Width = Area / Length = (1.36 × 10⁸ sq ft) / (1.6 × 10⁴ ft) = (1.36/1.6) × (10⁸/10⁴) = 0.85 × 10⁴ = 8.5 × 10³ ft
Therefore, the width of the park is 8.5 × 10³ ft.
The correct answer is 8.5 × 10³.
Divide 3.3 × 10⁴ by 5.5 × 10⁷. Choose the correct answer from below.
6 × 10⁻⁵
6 × 10⁻⁶
6 × 10⁻³
6 × 10⁻⁴
To divide 3.3 × 10⁴ by 5.5 × 10⁷, we divide the numbers and subtract the exponents:
(3.3 / 5.5) × (10⁴ / 10⁷) = 0.6 × 10⁻³
Therefore, the correct answer is 6 × 10⁻³.
that's correct?
I apologize for the mistake in my previous response. Let's correct it:
To divide 3.3 × 10⁴ by 5.5 × 10⁷, we divide the numbers and subtract the exponents:
(3.3 / 5.5) × (10⁴ / 10⁷) = 0.6 × 10⁻³ = 6 × 10⁻⁴
Therefore, the correct answer is 6 × 10⁻⁴.
