Answer:y=9
Step-by-step explanation:
Answer:
Approximately 54°
Step-by-step explanation:
So we know Angle A, the side opposite to Angle A, and the side opposite to Angle B (the angle we want to find). Given these circumstances, we can use the Law of Sines.
The Law of Sines states that:
The variables do not really matter. Instead, it's more important that the angle corresponding to the side lines up with each other.
Anyways, since we know Side A, Angle A, and Side B, let's use the first and second ratios:
Plug in 80° for A, 11 for a, and 9 for b:
Cross multiply to solve for B:
Divide both sides by 11:
Use the inverse sine function. And finally, use a calculator to solve:
The least common multiple of the three denominators is 16 because:
Change the fractions so that each fraction has a denominator of 16.

Answer:
12.)-5
13.)-16
14)-20
15)6
16)-13
17)1
18)-13
19)15
20)-10
Step-by-step explanation:
12.)-x=2+3
x=5/-1
so,x=-5
13.)-4=(-2×8+x)/8
-4×8=-16+x
-32+16=x
so,x=-16
14)(7×4+m)/4=2
28+m=8
so,m=-20
15)4n=34-10
n=24/4
so,n=6
16)-2a=22+4
a=26/-2
so,a=-13
17)a+3=2×2
a=4-3
so,a=1
18)-133+3=10x
-130=10x
so,x=-13
19)4+1=v/3
5*3=v
so,v=15
20)1=3+r/5
now,
Take LCM,
We get,
1=(3*5+r*1)/5
now,
by moving 5 into LHS
We get,
1*5=15+r
5=15+r
by moving 15 into left hand side,
We get ,
5-15=r
so,r=-10 because when we subtract smaller from bigger we have to take the sign of bigger.
Biweekly can either mean twice a week or every two weeks. We'll try both and see which one matches the answer choices:
If he gets paid every two weeks, that means he gets paid 26 weeks, since there are 52 weeks in a year. So we multiply $,3985 by 26 , which gives us $103,610.00. Since this is one of the answer choices, we can take this as our answer So the answer is the last one. Have a great day plz mark as brainliest!
