how to find constant of proportionality
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
A radioactive substance decays at a rate of 3.4% per day. If it starts at 200 grams, how
many days will it take for the substance to decay to less than 150 grams?
Answer: 9
Step-by-step explanation:
Since the percent is decaying, you subtract 3.4 from 100, which gets you 96.6
200(0.966)^9 gets you 146.5 which is less than 150

What is the length of segment C'D'?
units
Answer: 2 units
Step-by-step explanation:
The length of segment C'D' is 1 unit.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A'B'C'D' E' is the image of pentagon ABCDE under a dilation with a scale factor of 1/2.
We need to find the length of C'D'.
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.
The Length of segment CD is units.
Length of segment A'E' = 5/2 × Length of segment AE
Therefore;
Length of segment C'D' = 1/2 ×2 = 1 units.
Hence, the length of segment C'D' is 1 unit.

Simplify the inequality:
-12.4x+8x > -0.4x-5.2-2.7
Answer:
x < 1.975Explanation:
-12.4x + 8x > -0.4x - 5.2 - 2.7
Add similar elements: -12.4x + 8x = -4.4x
-4.4x > -0.4x - 5.2 - 2.7
Subtract -5.2 - 2.7: -7.9
-4.4x > -0.4x - 7.9
Multiply both sides by 10
-4.4x · 10 > -0.4x - 7.9 · 10
Refine
-44x > -4x - 79
Add 4x to both sides
-44x + 4x > -4x - 79 + 4x
Simplify
-40x > -79
Multiply both sides by -1 (Reverse the inequality)
-40x (-1) > -79 (-1)
Simplify
40x < 79
Divide both sides by 40
40x / 40 < 79 / 40
Simplify
x < ⁷⁹⁄₄₀
Turn the fraction into a decimal
x < 1.975
