I think 20% srry just woke up
D) People per hour, because the dependent quantity is the people
The dependent quantity is the quantity that relies on other variables of the situation. Therefore, the hours it takes relies on the amount of people that come into the theme park. People will continuously come into the park, they do not depend on anything. This is why it can not be C.
Answer: C & E
40% is equal to 0.4 as a decimal. As a fraction it is equal to 2/5 in simplest form.
In order to find the present you would have to multiple one of the numbers above by the initial value 84.
If you would like further explanation let me know. :)
Dont you have to have the beginning amount of water?
<span>Fuel consumed by Car A = 20 gallons
Fuel consumed by Car B = 30 gallons
Total distance = 950 miles
Let, distance covered by Car A = X miles
As the total distance covered is 950 miles,
Distance covered by Car B = 950 - X miles
Efficiency is calculated as total distance travelled divided by total fuel consumed.
Efficiency of Car A = X/20 miles/gallon
Efficiency of Car B = (950 - X)/30 miles/gallon
It is given that sum of efficiencies is 40. So,
(X/20) + (950 - X)/30 = 40
X/20 can be represented as 3X/60 and (950 - X)/30 can be represented as (2*(950-X)/60) to make the denominator same.
(3X/60) + (2*(950-X)/60) = 40
Simplifying, we get
(3X + 1900 - 2X)/60 = 40
Simpifying further, we get
X + 1900 = 2400
X = 2400 - 1900
X = 500
So, distance covered by Car A = 500 miles
Distance covered by Car B = 950 - 500 = 450 miles
To calculate fuel efficiencies,
Efficiency of Car A = 500/20 = 25 miles/gallon
Efficiency of Car B = 450/30 = 15 miles/gallon</span>
