Answer:
Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values). Arrange the numbers in order, find the middle number. (The middle value when the values are ranked).
I think the answer is 7 if i am not mistaking
The number is 5 and the factor is 1
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.

Answer:
No the ratio 3:4 is not equal to 4:5
Step-by-step explanation:
3:4 = 3/4 and 4:5 = 4/5
3/4 is equal to 0.75 and 4/5 is equal to 0.8
0.75 
0.8
therefore, 3:4 4:5
Hope this helps!
