Answer: 50 Books
Step-by-step explanation:
B = number of books in Ruben's collection BEFORE he bought new ones.
So 6 books were bought which increased his collection by 12%.
12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.
So then we know 0.12=6
*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.
Hope this helps! :)
1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25
2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24
For 3 and 4, is there a diagram?
A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
1.225 in.
2.360 in.
3.(450 in.)
4.900 in.
<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2
