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

Solve the inequality: l 2x + 5 l > 15
graph the line with the slope 3 passing through the point (2,-1)
Answer:
I can't draw at the moment but I'll try to teach how as best as I could.
Draw the Cartesian plane (x and y-axis)Locate the point (2, -1). To do this, go to x=2 then go down by 1 unit. Plot it or mark this point by a dot.Then from this dot, go 3 units to the right. After that, go up by 1 unit and mark that with a dot. By this time, you now have 2 dots.Connect them and that's it.Need help I’m very confused

The scale used on a map is 5 millimeters represents 32 kilometers. How many millimeters represent 160 kilometers?
160 mm
25 mm
1 mm
800 mm
Answer:
25 mm
Step-by-step explanation:
Set up a proportion where x is the number of millimeters for 160 kilometers
[tex]\frac{5}{32}[/tex] = [tex]\frac{x}{160}[/tex]
Cross multiply and solve for x:
32x = 800
x = 25
So, 25 millimeters represent 160 kilometers
Answer:
25 mm
Step-by-step explanation:
I hope I helped :)
Find the slope of 8y-2x=10
Answer:
1/4
Step-by-step explanation:
8y=+2x+10
Divide by 8

Y=1/4x+10
y=mx+b
M= slope
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

Hey there!
The answer to your question is 3480
There are two ways we can do this. I will show you both, so you know how to do it in the future:
The First Way ~ Parantheses First:
Step 1.) Add [tex]86[/tex] and [tex]34[/tex]
[tex]29(120)[/tex]
Step 2.) Multiply
[tex]3480[/tex]
The Second Way ~ Distribute First
Step 1.) Multiply [tex]29[/tex] and [tex]86[/tex]
[tex]29(34)+2494[/tex]
Step 2.) Multiply [tex]29[/tex] and [tex]34[/tex]
[tex]986+2494[/tex]
Step 3.) Add [tex]986[/tex] and [tex]2494[/tex]
[tex]3480[/tex]
