Answer:
Step-by-step explanation:
The constant of proportionality 'k' between two variables ( one independent and one dependent ) is given by :-
![k=\dfrac{\text{Value of dependent variable}}{\text{Value of independent variable}}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B%5Ctext%7BValue%20of%20dependent%20variable%7D%7D%7B%5Ctext%7BValue%20of%20independent%20variable%7D%7D)
In the given table, independent variable = Days
Dependent variable = Total Miles
From first row, Days = 3
Total Miles = ![1\dfrac{1}{5}=\dfrac{6}{5}](https://tex.z-dn.net/?f=1%5Cdfrac%7B1%7D%7B5%7D%3D%5Cdfrac%7B6%7D%7B5%7D)
Then, the constant of proportionality in the table
![k=\dfrac{\dfrac{6}{5}}{3}=\dfrac{6}{5\times3}=\dfrac{2}{5}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B%5Cdfrac%7B6%7D%7B5%7D%7D%7B3%7D%3D%5Cdfrac%7B6%7D%7B5%5Ctimes3%7D%3D%5Cdfrac%7B2%7D%7B5%7D)
Hence, the constant of proportionality in the table is
.
Volume= Length*Width*Height
V=(4)(3)(6)
V=72 yards cubed
The answer is A.
Which part do you need help on?
Answer:
1.6
Step-by-step explanation:
Since y = 8
And x = 5,
You divide both values by the X Value
8 divided by 5 = 1.6
5 divided by 5 = 1
the ratio is 1:1.6
So the constant is 1.6
It's important that you share the complete question. What is your goal here? Double check to ensure that you have copied the entire problem correctly.
The general equation of a circle is x^2 + y^2 = r^2. Here we know that the circle passes thru two points: (-3,2) and (1,5). Given that a third point on the circle is (-7, ? ), find the y-coordinate of this third point.
Subst. the known values (of the first point) into this equation: (-3)^2 + (2)^2 = r^2. Then 9 + 4 = 13 = r^2.
Let's check this. Assuming that the equation of this specific circle is
x^2 + y^2 = r^2 = 13, the point (1,5) must satisfy it.
(1)^2 + (5)^2 = 13 is not true, unfortunately.
(1)^2 + (5)^2 = 1 + 25 = 26 (very different from 13).
Check the original problem. If it's different from that which you have shared, share the correct version and come back here for further help.
