Answer:
Net A
Step-by-step explanation:
Net A fits best because the other options make an open prism or a prism who's sides overlap.
1 cm : 15 yd
Multiply this proportion by 5
5 cm : 75 yd
Multiply the original proportion by 8
8 cm : 120 yd
a) The dimensions of the field are 75 yd by 120 yd.
b) The area is (75 yd)*(120 yd) = 9000 yd^2.
<span><span><span>Angle A = </span>62°
</span><span><span>Angle B = </span>90°
</span><span><span>Side a = </span><span>45
The length of the board is side b
</span></span></span><span><span>Use the Law of Sines to find side b.</span><span>
b / sin(B) = a / sin(A)</span><span>
b / sin(90°) = 45 / sin(62°)</span><span>
b = (sin(90°) x 45) / sin(62°)</span><span>
b = 50.966
Rounded to the nearest inch is 51 inches.

Let x represent the # of 2-hour days and y the # of 3-hour days. Jimmy's study was spread over 10 days. Thus, x + y must sum up to 10. Also, 2x + 3y must sum up to 22 hours.Our system now looks like this:
x + y = 10
2x + 3y = 22
Multiply the first equation by -2: -2x - 2y = -20 Add the 2nd equation to this:
-2x - 2y = -20
2x + 3y = 22
------------------ y = 2 So Jimmy had 2 3-hour study days and 8 2-hour study days.
Note how these figures add up to 22: 6 + 16 = 22
Hope that help!
