For this case, the first thing we must do is define variables.
We have then:
x: length of the bookshelf
y: thickness of each book
The equation for the number of books is:
Substituting values we have:
Doing the calculation we have:
Answer:
200 copies of this book will fit on the bookshelf
Well, f 80% is 60 marks, you'll need 20% more to make it full, so it would be 15 more marks, which would be 75 total marks = 100% =)
I hope I helped! =D
Answer:
312 miles
Step-by-step explanation:
Shannon’s motorcycle gets 26 miles per gallon.
We need to find m, the number of miles she can travel on 12 gallons of gas.
It means,
In 1 gallon = 26 miles
In 12 gallon = (26 × 12) miles
= 312 miles
Hence, it will travel 312 miles on 12 gallon of gas.
The frequency stays the same and the wavelength decreases.
