By rotating the picture counterclockwise, it is clear that it is a square.

Calculate the length of one side of the picture by using coordinates (1, -3) and (2,1).
a = [(2-1)^2 + (1+3)^2]^0.5 = (1 + 8)^0.5 = 3
The area of the picture is 3^2 = 9.

Calculate the area of the red paper.
Area = 8*8 = 64

Calculate the area of the red paper after the photograph has been cut.
Area = 64 - 9 = 55

Answer: 55

Answer:

301.44 cubic units

Step-by-step explanation:

$volume \: of \: cone \\ \\ = \frac{1}{3}\pi {r}^{2} h \\ \\ = \frac{1}{3} \times 3.14 \times {(6)}^{2} \times 8 \\ \\ = \frac{1}{3} \times 3.14 \times 36 \times 8 \\ \\ = 3.14 \times 12 \times 8 \\ \\ = 301.44 \: {units}^{3} \\ \\ \red{ \bold{volume \: of \: cone = 301.44 \: {units}^{3}}}$

Allegra has a cell-phone plan that charges $65 per month and $0.10 for every minute that she uses the phone beyond what her plan

Bond [772]

It seems confusing, but it's just breaking down the steps for you. It's done the same as any other word problem.
a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
   The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
   8.40 = 0.10m
   84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.
