A lawn company advertises that they can spread 7,500 square feet of grass In 2 1/2 hours find the number of square feet of grass

Svetradugi [14.3K]

Ok in one hour the company can spread 3,000 square feet or sqft.

First we need to see which numbers make sense out of 7,500. First we remove the 500 and have 7,000, then we separate 3,000 and for each hour and we are left with 1,000 from here and the 500 we took out before. Now we have a total of 1,500 for the half hour which makes sense because if you add 1,500 for half an hour an 1,500 for another half an hour you get a total of 3,000 which is what we got for the hours above and if you add 3,000 which is for one hour and add 3,000 for the other hour or multiple 3,000 *2 which is the same thing as adding it twice and then add 1,500 for the half hour we get 7,500 total which means 3,000 I'd how much the company can spread in one hour.

A cylindrical milk storage tank needs to be built to hold 84.78 cubic feet of milk. The foundation for the tank has already been

Romashka [77]

Answer:

3 or 2.999 (probably 3)

Step-by-step explanation:

So the volume of a cylinder = πr^2 * h

h = height

r = radius

now we know the radius. Leaving us with a simple equation which is:

π*9*h = 9π*h = 84.78 =

π*h = 9.42

h = 9.42 / π = 2.99847912785......

but we can round this to 2.999 or just 3. if you use 2.999 the volume is 84.79 which is as close as I'm gonna try to get. And you might ask why we're rounding to 2.999 and not 2.998? This is because that huge number is the minimum. And 2.998 is smaller than that huge number, meaning it would technically be less than 84.78 cubic ft. But this doesn't really matter because the answer your teacher is probably looking for is 3.

Reference my work if you're are confused, however, it's really messy so sorry about that.
