Answer:
A =19.5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin A= opp/ hyp
sin A = 3/9
Take the inverse sin of each side
sin ^-1 sin A = sin ^-1 (3/9)
A =19.47122063
To the nearest tenth of a degree
A =19.5
<em>The range is 6.25 and the interquartile range is 3.25.</em>

Answer: you have $31 at the end of the week
Step-by-step explanation:
First, let's put this problem into an algebraic expression. We started off with $42. We then added $25 and took out $36 during the week. The expression for this problem is
42
+
25
−
36
.
Next, add 42 and 25 together to get
67
. We now have
67
−
36
.
Finally, subtract 36 from 67 to get
31
, our answer.
0.45 x 0.1 = 0.045 is the correct answer. Hope I helped.
