Answer:
You did not send a picture, so here is how you generally do it.
12 inches is 1 foot, and if you want to scale to be 1 inch to 10 feet it should be 10 times that, so 12 * 10 = 120. The scale is 120. Multiply the dimensions of the deck by 120 for your answer.

Answer: C) -48x^7y^3 </h3>
Explanation:
The coefficients are -8 and 6, which are to the left of the variable expressions. The coefficients multiply to -48. Based on this alone, the answer is between choice C or choice D.
For the variables, we add the exponents. The x terms multiply to x^5*x^2 = x^(5+2) = x^7
The y terms multiply to y^2*y = y^2*y^1 = y^(2+1) = y^3
Putting everything together, we end up with -48x^7y^3
5d<32+13
5d<45
D<9
Just simplify as much as you can.
Answer:
a) If the diameter is 400 feet wide, then the radius is half that, which is 200 feet wide.
b) The circumfernce is π times the diameter, which is 400 feet. 400×π≈1256.64
c) She is not correct. She squared 400, which is 160000, when she should have squared 200, which is 40000. Then, multiply by π.
40000 × π ≈ 125663.7
