Answer:
=19.81 in²
Step-by-step explanation:
We use the sine formula to find the area of the triangle in question.
In this formula we find the product of two adjoined sides with the sine of the angle between them.
The sides b and c are bound by the angle A.
Therefore area=1/2bcSin A
A=1/2×13.2 in×5.3 in× Sin 34.5
=19.81 in²
18. 1 3/4, 7/5, 1 3/10, 11/20, 1/4
19. 3 1/3, 2 1/5, 9/5, 9/10, 2/15
Answer:
The sum of heats gained is zero.
Step-by-step explanation:
K • 60 = 54
54 : 60 = 0.9
0.9 • 60 = 54
So the value of k is 0.9
<u>Answer: </u>
If they worked together it would take 4 hours for the machines to produce 100 widgets
<u>Step-by-step explanation:</u>
w = widgets hr = hour ph = per hour
Old machine - 50w = 5hr = 10ph
New machine - 30w = 2hr = 15ph
Old machine - 20w = 2hr
New machine - 30w = 2hr
<h3>Together - 50w = 2hr x 2 </h3><h3> Final: 100w = 4hr</h3>
I hope this helped!
