La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
Answer:
We can note that this part of the graph is a linear function. This means that is has a general form: y = mx + c where m is the slop and c is the y-intercept (value of y at x=0). For the slope, we will use the points (0,2) and (3,5) to calculate it as follows: m = (y2-y1)/(x2-x1) = (5-2)/(3-0) = 1 For the y-intercept, we can note that at x=0, the value of y is 2. This means that the equation of the first part of the graph is: y = x + 2

Answer:
25
Step-by-step explanation:
Expression: <em>(2⁸ ⋅ 5⁻⁵ ⋅ 19⁰)⁻² ⋅ (5⁻²/2³)⁴ ⋅ 2²⁸</em>
Inner-most powers: 2⁻¹⁶ • 5¹⁰ • 1 • 5⁻⁸/2¹² • 2²⁸
Combine like terms: 2¹² • 5²/2¹²
Cancel out: 5²
Solve: 25
<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>
=============================================
Explanation:
If you save 65%, then you pay the remaining 35%
0.35x is the final price when x is the original price
0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35
57.14 goes in the first box
--------------
This must mean 80 goes in the other box.
Here's the steps on how to get 80
If you save 75% then you pay the remaining 25%
0.25x = 20
x = 20/0.25
x = 80
80 goes in the second box
