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)
Using the slope-intercept form, the slope is 4
Answer:
y=40
Step-by-step explanation:
A direct variation is a relationship between two numbers where the output equals the input times a constant.
The equation for a direct variation can be written as
y=kx
We can figure out the y value of the second coordinate by finding out what the constant (k) is. We can do that by plugging in the first coordinates into the equation.
y = kx
10 = 6k
10/6 = k
We can solve for y by plugging this constant, and the second coordinate into the equation.
y=kx
y=10/6(24)
y=40
