Mrs Lim bought a number of plates at an average price of $6. She decided to buy another plate which cost $18. The average price
soldi70 [24.7K]

Answer:  6

<u>Step-by-step explanation:</u>

Let x represent the number of plates bought for $6

Let y represent the Total number of plates bought = x + 1

<em>Remember that Mrs. Lim bought another plate for $18</em>

Total cost ÷ Total plates = Average Cost

\dfrac{6x+18}{x+1}=8\\

6x + 18 = 8(x + 1)

6x + 18 = 8x + 8

       18 = 2x + 8

       10 = 2x

        5 = x

y = x + 1

  = 5 + 1

  = 6

If r = 6 units and h = 13 units, what is the volume of the cylinder
Andrews [41]

Answer:

v=1460.26536188 units^3

Step-by-step explanation:

Volume for a cylinder is:

V=πr^2h

Substitute 6 in for r and 13 in for h

V=π(6^2)(13)

V=π(36)(13)

V=π468

v=1460.26536188 units^3

Hope this helps! :)

an empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute. At the same time another 1200 gallon
ser-zykov [4K]

Answer: 80 minutes

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each tank:

An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.  

So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)

  • Tank 1 =0 (empty )+ 6m  =6m

The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.

  • Tank 2 = 1200-9m

So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)

Since both tanks will have the same amount of water:

6m = 1200-9m

Solving for m  (minutes):

6m+9m= 1200

15m = 1200

m= 1200/15

m= 80 minutes

Feel free to ask for more if needed or if you did not understand something.
