the area of a circle is
pi×r²
that is for the whole circle, which is the same as 360 degree arc.
now that we have only 254 out of the total of 360 degrees, the sector area is
pi×r² × 254/360
pi×9² × 254/360 = pi×9 × 254/40 = pi×57.15 =

Given JAM and segment PB such that PB JM, what is the missing justification in the proof that JP/PA = MB/BA
Answer: AA similarity posulate
Step-by-step explanation:
In ΔAJM and ΔAPB,
∠PAB = ∠JAM,
Also, since PB || JM, the corresponding angles formed by these two parallel lines with the line AJ are equal i.e.
∠AJM = ∠APB
So, using the AA similarity postulate, we can say that ΔAJM is similar to ΔAPB

What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?
Answer:
The distance is 1.41 to nearest hundredth.
Step-by-step explanation:
The line y = x + 3 passes through the point (0, 3) on the yaxis.
Find the perpendicular line passing through this point:
y - 3 = -1(x + 0)
y = -x + 3
Now find the point where this line intersects the line y = x + 1:
y = -x + 3
y = x + 1
-x + 3 = x + 1
3 -1 = x + x
2x = 2
x = 1
and y = 2
So this point is (1, 2)
We require the distance between this point and (0, 3)

Identify a pattern in the given list of numbers. Then use this pattern to find the next number. 17,7,-3,-13,-23
Answer:
-33
Step-by-step explanation:
The sequence is descending so the nth term would be -10n and the 0 term would be 27 so the nth term for the sequence would be -10n +27.
The question asks you to find the 6th term so (-10 x 6) + 27 = -60 + 27 = -33
whats the next term of arithmetic sequence 24,16,8,0
Explanation:
The jump from 24 to 16 is -8
The jump from 16 to 8 is also -8
Each time we need a new term, we add on -8 which is the common difference. So we'll add -8 to 0 to get 0 + (-8) = 0 - 8 = -8 as the next term.
If you wanted another term after that, then it would be -8 + (-8) = -8-8 = -16
Then the next term after that is -16+(-8) = -16-8 = -24, and so on.
Answer:
-8
Step-by-step explanation:
each time its going down by 8 meaning it would be -8

Given = 3(x - 4) + 5x = 9x - 36
Step 1 = 3x - 12 + 5x = 9x - 36
Step 2 = 3x + 5x - 12 = 9x - 36
Step 3 =› 8x - 12 = 9x - 36
Step 4 => 8x - 8x - 12 = 9x - 8x - 36

(e) The 9 of hearts or a jack
Answer:
3/44/137/262/135.52Step-by-step explanation:
(a)
Probability (A heart or a black card) = 13 + 26 / 52Probability (A heart or a black card) = 39/52Probability (A heart or a black card) = 3/4(b)
Probability (A heart or a jack) = 13 + 3 / 52Probability (A heart or a jack) = 16/52Probability (A heart or a jack) = 4/13(c)
Probability (A heart and the ace of clubs) = 13 + 1 / 52Probability (A heart and the ace of clubs) = 14/52Probability (A heart and the ace of clubs) = 7/26(d)
Probability (A 9 or a jack) = 4 + 4 / 52Probability (A 9 or a jack) = 8/52Probability (A 9 or a jack) = 2/13(e)
