Answer:
15n
Step-by-step explanation:
Amal has a bookcase with n shelves. There are 15 books on each shelf. Using n, write an expression for the total number of books.
The expression for the total number of books is given as:
Number of shelves × Number of books in each shelf
= n × 15 books
= 15n
Which place value are trying to round the number?
Answer:
4/76 or simplified as 1/19
Step-by-step explanation:
5/20 is for the probability of the first balloon
4/19 is for the probability of the second balloon
5/20 can be simplified to 1/4 so 1/4 x 4/19 = 4/76
4/76 can also be simplified to 1/19
Answer:
Center = (4, -5)
radius = 6
======================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
Rewrite the given equation into this form
(x-4)^2 + (y- (-5))^2 = 6^2
We can see that (h,k) = (4,-5) is the center and r = 6 is the radius.
