There are 100 cm in a meter so 16 cm is equal to 1600/48
Answer:
-1/4
Step-by-step explanation:
Hello!
The rate of change is also known as the slope.
Standard equation of a line: y = mx + b
- y: output
- m: slope
- x: input
- b: y-intercept
So, if we match the standard form to the given function:
-1/4 is m, or the rate of change.
Answer:
A. x = 4
B. ∠C = 80°
Step-by-step explanation:
<h3>A.</h3>
The sum of interior angles in a pentagon is 540°. We can write an equation for the sum of angles using this fact. Clockwise from lower left, we have ...
140° +(20x)° +100° +(16x +16)° +(160 -5x)° = 540°
31x +416° = 540° . . . . . . collect terms
31x = 124° . . . . . . . . . . subtract 416°
x = 4
__
<h3>B.</h3>
The measure of angle C is found by substituting the value of x into the given expression for angle C.
(16x +16)° = (16(4) +16)° = 80°
Angle C is 80°.

<em>Additional comment</em>
It can be useful to remember that the sum of <em>interior</em> angles of an n-gon is ...
(180°)(n -2)
This can be derived from the fact that the sum of <em>exterior</em> angles is always 360°.
These relations apply to <em>convex</em> <em>polygons</em>. YMMV when there are reflex angles or when sides cross each other.
They both weigh the same because it says a pound of feathers and a pound of pennies
So both the pennies and the feathers weigh 1 pound!
Hah I didn’t fall for it this time :))
