Answer:
53
Step-by-step explanation:
72 = x + 3x - 4
72 = 4x - 4
72 + 4 = 4x - 4 + 4
76 = 4x
76/4 = 4x/4
x = 19
3(19) - 4 = 53

Arc length = angle*radius
Degrees to radians: multiply by pi/180
Arc length = (pi/180*6)*6 = 36/180*pi = pi/5.
The answer is D.
The order of these numbers from smallest to largest is:
(-1)2, -1 2/5, -1.4, (1/2)2
-1 2/5 and -1.4 are technically the same, though.
Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
The answer to this question is 10. The working out is shown in the image attached.
*** Sorry instead of writing 170 I wrote 270 for the big angle.. other than that it's correct
or another way to solve this is....
we know that a straight line is 180 degrees and the angle APD is 170 all we need to do is subtract 170 from 180 to get the answer of DPB
Hope this helped
