36:21 in simplest form is 12:7, because 3 goes into both 36 and 21. Simplifying ratios is essentially the same thing as simplifying fractions. Once we have 12:7, we can't reduce any further, because 7 is prime.
Hope this helps!
Answer:the amount that the bookstore pay the publisher for the book is $64.4
Step-by-step explanation:
Let x represent the amount that the bookstore pay the publisher for the book.
The college bookstore marks up the price that it pays the publisher for a book by 35%. This means that the value of the mark up would be
35/100 × x = 0.35 × x = 0.35x
Therefore, the amount that the bookstore is selling the book would be
x + 0.35x = 1.35x
If the selling price of a book is $ 87.00, then it means that
1.35x = 87
x = 87/1.35 = 64.4

Answer:
2160 cm³/hour
Step-by-step explanation:
By default, we know that the volume of a cube is given as s³
Thus, the Volume function, V = s³
When we differentiate with respect to time we have
dV/dt = 3s² (ds/dt), where ds/dt = 0.2
Then we go ahead and substitute all the given parameters
dV/dt = 3 x 60 x 60 x 0.2
dV/dt = 10800 * 0.2
dV/dt = 2160 cm³/hour
This means that the volume decreases by a rate of 2160 cm³/hour at the instant its edge is 60 cm
