Answer:
100rz cents.
Step-by-step explanation:
The price of cement with respect to its weight is proportional.
So, we can write p ∝ w
where p is the price in dollars and w is the weight of the cement in pounds.
⇒ p = kw ............... (1) {Where, k = proportionality constant}
Given that, one pound of cement cost r dollars.
So, from equation (1), we can write
r = k(1)
⇒ k = r
So, the equation becomes p = rw .............. (2)
Now, for w = z pounds, the price will be p = rz dollars. {From equation (2)}
Therefore, the price of z pounds in cents will be 100rz cents. (Answer)

Answer:
<h2>The distance between points A and B is 8.5 units, approximately.</h2>
Step-by-step explanation:
In the image attached you can observe a representation of the problem.
We have to find the distance between points A and B, which have coordinates (6,0) and (0,6), respectively.
The definition of distance between to given points is

Using points A and B, the distance between is

Therefore, the distance between points A and B is 8.5 units, approximately.
