The value of angle Y is -120° because you know that angle S is half of angle Y and -60*2 equals -120°. Hope that helps!
You can model a percent many ways. Compare fractions, decimals and percents using area models. You can also use a pi chart, bar graph, and so many other graphs when using percentages. Hope this helps you.
Answer:
light blue
Step-by-step explanation:
Step-by-step explanation:
A(t)=P(e^(rt))
Insert the values as follows:
The equation for "continual" growth (or decay) is A = Pe^(rt), where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).
34820=P(e^((.78)(5)))
34830=P(49.4024)
704.82335
Hope that helps :)
You started out as if it was going to be a probability problem, but it turned out to be a simple binary counting problem.
It really doesn't matter how many of each color are in the bag, or how many marbles there are in the bag all together. I think you're just asking how many ways there are to pull out two white ones and two black ones. That's exactly the same question as "How many 4-bit binary numbers can be written with two 1's and two 0's ?"
It's easy to draw up that list. You start out like this:
0011, 0101, 1001, 0110, 1010, 1100 .
Gosh. I just wanted to start out doing the list, but I think that's all of them.
There are six (6) ways.
WWBB, WBWB, BWWB, WBBW, BWBW, and BBWW .
