Answer:
a+b
Step-by-step explanation:
Answer:
26 5/12
Step-by-step explanation:
n − 2/3 = 25 3/4 Add 2/3 to both sides
n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine
n = 25 3/4 + 2/3
Work with the fractions
3/4 + 2/3 The lowest common denominator is 12
(3*3)/(3*4) = 9 / 12
(2*4)/(3*4) = 8/ 12
9/12 + 8/12 = 17/12 = 1 5/12
Now you need to add 1 to 25
1 + 25 = 26
And add the fraction 5/12
The answer is 26 5/12
Because X is opposite of the 38° angle and 35 is adjacent to the 38° angle, you would use tan. To set up the equation you would put X over 35 and set an equal to 38(tan). Then you would multiply both sides by 35 to cancel out the 35 on the bottom of the X. When you multiply 38(tan) by 35, you get X equals 27.
Answer:
tan (a+b) = 2.27 or (345/152)
Step-by-step explanation:
a and b are in the fourth quadrant
sin a = -12/13 tan a = - 12/5 = - 2.4
cos b = 20/29 tan b = - 21/20 =.1.05
tan (a+b) = (tan a + tan b) / (1 - tan a * tan b)
= (-2.4 + - 1.05) / ( 1 - (-2.4)*(-1.05))
= (-3.45) / (-1.52)
= 2.27
Answer:
720 (If you are counting 10% of 820, not 10% of 100)
Y = 800(1 - 0.1)
Y = 800(0.9)
Y = 720
