Answer:
5.1
Step-by-step explanation:
I'm guessing you wanted me to divide these to find the quotient.
If you divide these using long divison, you should get the answer of
5.1
Answer:
3/40
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 9 and 120 is 3
Divide both the numerator and denominator by the GCD
9 ÷ 3
120 ÷ 3
Reduced fraction:
3/40
Answer:
A is the only number that falls between 3 and 4
Step-by-step explanation:
1n-12
Step-by-step explanation:
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
