Mr. Tomas ereated a 2-foot wide garden path around a circular garden. The radius of the garden is 7 feet. He wants to cover the path in stones. If Mr. Tomas
needs 1 bag of stones for every 6 square feet of path, how many bags of stones
will he need to cover his garden path?

17 bags.

Step-by-step explanation:

We can think of the area of the path, as the difference between the area of a circle with a radius of 9ft (the 7 ft of the circular garden plus the 2ft of the path) and the area of a circle with a radius of 7ft.

Remember that the area of a circle with radius R is:

R = pi*R^2

Where pi = 3.14

Then the area of the path will be:

A = 3.14*(9ft)^2 - 3.14*(7ft)^2 = 100.48 ft^2

Now, we know that Mr. Tomas needs 1 bag of stones for every 6 square feet of path.

Then let's see how many times we have 6ft^2 in the 100.48 ft^2 of the area, this is equal to the quotient between  100.48 ft^2 and 6ft^2

N = (100.48 ft^2)/( 6ft^2) = 16.75

This means that we will need 16.75 bags of stones, but we can not have a 0.75 of a bag, then we should round up our number to 17.

Then Mr. Tomas will need 17 bags of stones to cover his garden path.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
