There are a lot of things that are equivalent to 16/81.
16/81 = 0.197530864
Or we can keep multiplying 2 to the numerator and denominator:
16/81 = 32/162 = 64/324 = 128/648
The median is the number in the middle when all of the numbers are placed in order (from lowest to highest).
15; 17; 19; 42; 78; 85; 93
The answer in this case would be 42.
Answer:
Numbers are 14 and 8
Step-by-step explanation:
Let the 2 numbers be x and y.
Write 2 equations:
x + y = 22
x - y = 6
Solve by substitution:
x - y = 6
x = y + 6
Plug into the other equation:
(y + 6) + y = 22
2y + 6 = 22
2y = 16
y = 8
Plug into either equation:
x + 8 = 22
x = 14
Numbers are 14 and 8
Part (a)
<h3>Answer: 12.1</h3>
-----------------------
Work Shown:
We'll apply the sine rule since we have a known opposite side of AB = 10 and an unknown hypotenuse we want to find BD.
Focus on triangle ABD
sin(angle) = opposite/hypotenuse
sin(D) = AB/BD
sin(56) = 10/x
x*sin(56) = 10
x = 10/sin(56)
x = 12.062179
x = 12.1
Make sure your calculator is in degree mode.

Part (b)
<h3>
Answer: 15.1</h3>
-----------------------
Work Shown:
Draw an xy coordinate grid.
Place point A at the origin (0,0).
Point B is 10 units above this, so B is at (0,10).
Point C is at (18,10) since we move 18 units to the right of B.
Point D is at approximately (6.745085, 0). The 6.745085 is from solving tan(56) = 10/x for x.
Refer to the diagram below.
Apply the distance formula for the points C and D.


Segment CD is roughly 15.1 cm long.
0.035 is 35/1000, which is 7/200 when you take out a 5 from both sides.
