40 inches because a rectangle has 2 sets of parallel lines and if the width and length are 10 then you just have to add up all the sides.
Answer:
A: 244 pounds
B: 122 pounds
C: 274 pounds
Step-by-step explanation:
We have A+B+C = 640; A=2B; C=A+30. Substituting the last into the first gives ...
A + B + (A +30) = 640
2A +B = 610 . . . . . . . . . . . . subtract 30
Substituting the second into this equation gives ...
2(2B) +B = 610
B = 610/5 = 122 . . . . . divide by 5
A = 2B = 244 . . . . . . . .find A from B
C = A+30 = 274 . . . . . find C from A
Box A weighs 244 pounds; box B weighs 122 pounds; box C weighs 274 pounds.

Answer:
A number
Step-by-step explanation:
By graphing the given equation
<span>r = 4 - 3 sin θ
We find that </span><span>the graph is symmetric about the y-axis
The graph of the given equation is attached below

Some information about the given equation:
the given equation is like the form of the </span>
Cardioid
A curve that is somewhat heart shaped. A cardioid can
be drawn by tracing the path of a point on
a circle as the circle
rolls around a fixed circle of the
same radius.
The equation is usually written in polar
coordinates.
Equations of Cardioid:
r = a ± a cos θ (horizontal)
or <span>r = a ± a sin θ (vertical)</span>
