Answer:
The number of students who liked the book was 64.
Step-by-step explanation:
After reading a book for English class, 100 students were asked whether or not they enjoyed it.
Now, given that nine twenty-fifths of the class did not like the book.
So, of the whole class did not like the book.
Then, the fraction of the class who did like the book was .
Therefore, the number of students who liked the book was . (Answer)
Step-by-step explanation:
Let x = m² and y = 4n.
Then m⁶ - 64n³ = x³ - y³
= (x - y)(x² + xy + y²)
= (m² - 4n)(m⁴ + 4m²n + 16n²).
Answer:
Step-by-step explanation:
it should be (x+3)2=5
xx2=2x+5=5
5-5=0
x=2
Answer:40 in
Step-by-step explanation:
The formula for calculating the circumference of a circle is given as
C = 2πr
Let r be the radius of the smaller circle and R be the radius of the bigger circle, the ratio of their circumference is given as 2 : 5 , this implies that
2πr : 2πR = 2 : 5
Which could be written as =
r = 16 , the the equation becomes:
=
Cross multiply
2R = 16 x 5
2R = 80
R = 80/2
R = 40 in
