Answer:
15 questions he missed
Step-by-step explanation:
We apply the Law of Sines
<span>a/sin A</span> = <span>b/sin B</span> = <span>c/<span>sin C</span></span>
We have that b = 12, B = 15 degrees
<span><span>C = 90 degrees</span></span>
....> c/sin(90) = 12/sin(15)..............> c = 12/0.258 = 46.3644
I believe it’s c.
Hope this helps
There were 10 small boxes shipped and 12 large boxes shipped.
Step-by-step explanation:
Given,
Weight of each small box = 35 pounds
Weight of each large box = 85 pounds
Total boxes = 22
Total weight of shipment = 1370 pounds
Let,
Number of small boxes = x
Number of large boxes = y
According to given statement;
x+y=22 Eqn 1
35x+85y=1370 Eqn 2
Multiplying Eqn 1 by 35
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 50
Putting y=12 in Eqn 1
There were 10 small boxes shipped and 12 large boxes shipped.
