A. The ratio of soccer balls to all balls are 4:25
All the balls combined are 50 balls
8 of the balls are soccer balls so that makes the ration 8:50
In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
Answer:
answer is b
Step-by-step explanation:
Answer:
D. 13
Step-by-step explanation:
You can do the product in the straight-forward way ...
... (3 -2i)(3 +2i) = 3·3 +3·2i -3i·3 -(2i)(2i)
... = 9 +6i -6i -4i² . . . . . note the middle two terms cancel
Recognize that i = √-1, so i² = -1. Then the sum is
... = 9 -4(-1) = 9+4 = 13

Your graphing calculator can do this product, too.
100%+5 1/2%= 105.5%
105.5/100=1.055
20*1.055=21.1

Hope this helps :)
18 - 25 = -7
11 - 18 = -7
4 - 11 = -7
The common difference is -7.
