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)
Multiply 7 times 50 and 7 times 6 then add them
ex: [(7 X 50) + (7 X 6)]
If written as a decimal, 9 x 1/10 would be 9 x 0.1,
6 x 1/100 would be 6 x 0.01, and 4 x 1/1000 would be 4 x 0.001.
