Answer:

Part A : Area = Xft . X ft

Part B: A= 6ft . 4ft

Part C: P = xft +x ft + xft +x ft

Step-by-step explanation:

Hi, for part A and part B we have to apply the area formula (for a rectangle)

Area = L . W

Where:

L: Lenght

W: Width

Replacing with the values given:

Part A= Area of the painting (grey area)

A = Xft . X ft

Part B = Area of the frame (white section)

A= 6ft . 4ft

For part C we have to apply the perimeter formula:

Perimeter = 2 L + 2 W

Replacing with the values given:

P = 2xft +2xft

or

P = xft +x ft + xft +x ft (sum of all sides)

A well mixed tank with a capacity of 1500 gals originally contains 1000 gallons of freshwater. One pipe containing 1/2 lb of sal
Illusion [34]

Answer:

400 lb of salt

Step-by-step explanation:

Let us assume the water flows into the rank for x minutes.

There is an initial of 1000 gallons of water in the tank and water flows in through one pipe at 4 gal/min and through another pipe at 6 gal/min. In x minute, the amount of water in the tank = 1000 + 4x + 6x = 1000 + 10x

Water flows out at 5 gal/min, therefore in x minute the amount of water in the tank = 1000 + 10x - 5x = 1000 + 5x

The tank begins to overflow when it is full (has reached 1500 gallons). Therefore:

1500 = 1000 + 5x

5x = 1500 - 1000

5x = 500

x = 100 minutes.

1/2 lb salt per gallon flows into the tank at 4 gal/min and 1/3 lb of salt is flowing in at 6 gal/min, in 100 min the amount of salt that entered the tank = 4 gal/min × 100 min × 1/2 lb/gal + 6 gal/min × 100 min × 1/3 lb/gal= 400 lb

Therefore the amount of salt is in the tank when it is about to overflow = 400 lb of salt
