Answer:
Step-by-step explanation:
These are logically difficult, so it makes sense to me you're asking about this.
so A = 1/2 (big arc - small arc)
and 360 = big arc + small arc
then
360 - small arc = big arc
so rewrite the top equation
A = 1/2(360-small arc -small arc)
63 = 1/2( 360 - 2 small arc)
2* 63 = 360 - 2 small arc
126 = 360 - 2 small arc
2 small arc = 360-126
2small arc = 234
small arc = 234/2
small arc = 117
x = 117°
Answer:the mean is greater than the median
Step-by-step explanation:
To answer this question, you must first understand what a fourth is. 1/4 is simply when a one is split into four parts, and you take one of those parts. Imagine you have a pie, and you cut it into four equal pieces. If you take one of those four pieces, you have one fourth of the pie. So if you have three fourths of the pie, you have three pieces out of the four total. This question is basically asking: "If you have three pieces out of four, how many pieces do you need to make one whole pie?"
Therefore, the problem looks like this:
3/4 + ?/4 = 1
and therefore the answer is 1/4 because you only need one fourth to make a whole number.
Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
