Given :
Ruth wants to buy a skateboard for $44.
She has $100 in her account. She spent $11.36 to buy stationary.
She also wants to buy some comic books for $3.72 each.
To Find :
The maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard.
Solution :
Money left after buying skateboard and stationary is :
Money left = $(100 - 11.36 - 44)
Money left = $44.64
Number of comic she can buy is :
Therefore, she can buy a maximum of 12 books.
Hence, this is the required solution.
Answer: 256 units squared
Step-by-step explanation:
So basically you times 4*4*2*8.
Answer:
The expression provided by the area (square meters) is given by: 
.
Step-by-step explanation:
The area of the algae colony is a function of the radius r (meters), so 
.
The radius of the circle formed by the algae colony is a function of time t (in minutes), so 
. So,
[Substituting the expression for radius]
Then the expression provided by the area (square meters) is given by: .
No graph, so cannot be precise.
But you can apply rotation 270 CCW = rotation -90 CCW
r_[90] : (x,y) -> (y,-x)
