Answer:
80
Step-by-step explanation:
<u><em>A = Area of First Rectangle </em></u>
<u><em>B = Area of Second Rectangle </em></u>
<u><em>w = Width</em></u>
<u></u>
12(w)=320+B (1st Equation)
8(w) = B (2nd Equation)
w=B/8 <em><u>(Plug this value of w into the first equation)</u></em>
12B/8 = 320 +B <u><em>(you get this)</em></u>
12B= 2560 + 8B <u><em>(Simplify)</em></u>
4B = 2560
B =640 <em><u>plug this value into the 2nd equation</u></em>
8(w) = 640
w = 80
<em>To Test This</em>
12x80 = 960
8x80 = 640
<h3>960 - 640 = 320
<u><em>Therefore the answer is correct the width is 80</em></u></h3>

Answer:
see below
Step-by-step explanation:
You can use the law of sines to choose the correct answer:
b/c = sin(B)/sin(C) ≈ 0.8
For the first answer choice,
sin(44.3)/sin(60.7) ≈ 0.8009 . . . . . . as close as you expect to get
____
The second answer choice has the wrong ratio of sines.
The third answer choice has B > C, which it cannot be since b < c.
_____
The law of cosines can be used to find "a":
a^2 = b^2 + c^2 -2bc·cos(A) = 102500-100000cos(75°) ≈ 76,618
a ≈ √76618 ≈ 276.8 . . . . . . matches the first answer choice
Answer:
each bottle of juice costs $2.44
Step-by-step explanation:
x=bottle of juice
2.13+3x=9.45
subtract 2.13 from each side and get 3x=7.32
divide both sides by 3
and get x=2.44
The percentage would be 55.9% girls overall in the class because 19/34 as a percentage is 55.882352941177% but to round it would be 55.9%.
