Answer: 5/66 (I'm so sorry if this is wrong)

Step-by-step explanation: First you divide 10 and 3 3/4. 10 ÷ 3 3/4 = 0.0757575757575.

To turn that back into to a fraction, let X equal the decimal number

Equation 1:

X = 0.0757575757575 (1)

With 12 digits in the repeating decimal group,

create a second equation by multiplying

both sides by 1012 = 1000000000000

Equation 2:

1000000000000X = 75757575757.5757575757575 (2)

Subtract equation (1) from equation (2)

1000000000000X = 75757575757.5757575757575...

X = 0.0757575757575...

999999999999X = 75757575757.5

We get

999999999999X = 75757575757.5

Solve for X

X = 75757575757.5/999999999999

Multiply to eliminate 1 decimal places.

Here you multiply top and bottom by 1 10's

= 101 = 10

75757575757.5/999999999999 × 10/10 = 757575757575/9999999999990

Find the Greatest Common Factor (GCF) of 757575757575 and 9999999999990, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 151515151515,

757575757575/9999999999990 ÷ 151515151515/151515151515 = 5/66

Therefore

X = 5/66

In conclusion,

0.0757575757575 = 5/66

a fishing boat accidentally spills 15 barrels of diesel oil into the ocean. each barrel contains 42 gallons. if the oil film on

bezimeni [28]

The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².

<h3>What is meant by volume?</h3>

Volume is defined as the amount of three-dimensional space enclosed by a closed surface.

The liter (L) is the metric system's base volume unit, with several extended volume units also available.
There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.

Now, as per the given question;

First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:

15×42 gal = 630 gal

This volume must be converted to square meters:

V = 630 gal × (0.00379 m³/ gal

V = 2.4 m³

The thickness (height) of a oil film in meters is required:

h = 250 nm × (m/10⁻⁹nm)

h = 2.5 × 10⁻⁷m

The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.

A = V/h

A = 2.4 m³/2.5 × 10⁻⁷m

A = 9.6 × 10⁶ m²

Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².
