There are (49)5 • 40 books at the library. What is the total number of books at the library? (4 points)

It looks here that you have a normal math problem; the (49)5 parentheses just mean multiply. 49*5=245. Once that's done, multiply 245*40, and you get 9800. Thus, there are 9,800 books in the library.

5 times 40 times 49 equals 9800 because you do 5 time 4 and that's 20 and you add a 0 and you multiply by 49 to get 9800.

Answer:

$b)\,\frac{dW}{dt}=kt\sqrt{W}, \,W(0)=10$

Step-by-step explanation:

Initial number of sick wolves = W(0) = 10

At time t, no. of sick wolves = W(t)

Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:

$\frac{dW}{dt}=kt\sqrt{W}$

Mathematical model of above case is:

$\frac{dW}{dt}=kt\sqrt{W}, \,W(0)=10$

What is the base of the expression 11^12? A. 3 B. 11 C. 12 D. 21

lisov135 [29]

<h3>Answer: B. 11</h3>

An exponential has the base at the bottom, or the lower portion. Think of "basement" to help remember this. The exponent is the number up top, so 12 is the exponent.
