Jennifer has a string attached to the end of a buoy with extra string coiled on the bottom of the tank. She measures the length

of the string from where it is attached to the buoy to the bottom of the tank as he adds more water to the tank. The length changes linearly as water is added. The table shows the collected data. What is the slope of the line that models the data?

I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.

Because of the commutative property of multiplication, it is true that
rewona [7]

Answer:

It is Commutative

Step-by-step explanation:

An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.

Given the operation ∆ defined by:

a∆b=a X b

a=\frac{3}{4}, b=4

a∆b=\frac{3}{4}X4

=\frac{3X4}{4}=3

Similarly, for the right hand side.

(\frac{4}{3})^{-1}=\frac{3}{4}

Therefore:

b∆a=4X \frac{3}{4}

=\frac{4X3}{4}=3

These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:

a∆b=b∆a=3

How to find the circumference of a circle​
Romashka [77]
  1. C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7.
  2. The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle. Again, you can plug π into your calculator to get its numeral value, which is a closer approximation of 3.14.
