In a recent year, 19.4% of all registered doctors were female. If there were 52,500 female registered doctors that year, what wa
sukhopar [10]

Answer: 10,185 registered female doctors.

Step-by-step explanation: We basically want to find how many females were doctors, if 19.4% of the 52,500 females were registered doctors. Basically we want to find 19.4% of 52,500. We will write an equation that works to solve this problem.

19.4/100 = x/52,500 (This equation represents that 19.4% out of 100% is x out of the 52,500 registered doctors.) Solve for x.

19.4/100 x 52,500 = x/52,500 x 52,500.

(19.4 x 52,500 = 1,018,500/100 = 10,185. And, x/52,500 x 52,500 = x.

10,185 = x.

So, 19.4% of all registered doctors would be 10,185 females out of 52,500 females.

If one pound of cement cost r dollars, what is the price of z pounds in cents
slavikrds [6]

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)
