The Smiths have a​ rectangular, above-ground swimming pool. The manufacturer says that the pool holds​ 14,040 gallons of water when filled to capacity. After it is​ filled, Mr. Smith follows the​ manufacturer's recommendation of adding 1 ounce of chlorine for every​ 2,700 gallons of​ water, every other day. About how many pounds of chlorine will Mr. Smith add to the pool in 3​ weeks?

Answers

Answer:

54.6 ounces

Step-by-step explanation:

14,040/2,700=5.2

3 weeks is 21 days

21 days divided by 2 because every other day is 10.5 days

5.2 times 10.5 is 54.6

54.6 ounces because 14,040 divided by 2,700 you will get 3 week and the 21 days so you would do is 21 days divided by 2 because every other day is 10.5 days. So, than 5.2 *10.5 is 54.6.

Answer:

60 units²

Step-by-step explanation:

Area of triangle is [tex]\frac{1}{2}[/tex]×b×h

b is the length of the base of the triangle

h is the height/altitude of the triangle

considering, you are given the base and height, inserting it into the formula will solve the problem.

Answer:

432 ft^2

Step-by-step explanation:

The formula for the area of a circle is A=pi*r^2. In this case, because 3 is pi, it's A=3*r^2. We have the diameter of the circle, but we need the radius. The radius is 1/2 the diameter, so it's 12. 12^2=144, and 144*3 is 432, so that's our answer.

Hope this helps!

Answer:

432 ft to the power of 2

Step-by-step explanation:

Step-by-step explanation:

Finding the Surface Area :

Area (2 triangles) + Base rectangle + Left rectangle + Right rectangle2 x 1/2 x 4 x 5 + 9 x 5 + 6 x 9 + 5 x 920 + 45 + 54 + 4565 + 99164 cm²

Step-by-step explanation:

just take a deep breath, shake your limbs, and then focus on it again.

the surface consists of 5 areas :

front and back triangles (2)

left rectangle

right rectangle

floor rectangle

the area of a rectangle is simple :

length × width

the area of a triangle is

baseline × height / 2

each of the front and back triangles has an area of

5 × 4 / 2 = 5×2 = 10 cm²

both of them have then 10×2 = 20 cm²

the left rectangle is

9×6 = 54 cm²

the right rectangle is

9×5 = 45 cm²

the floor rectangle is also

9×5 = 45 cm²

so, the total surface area is

20 + 54 + 45 + 45 = 164 cm²
