Answer:
C. The equation x = 50y represents this situation.
Step-by-step explanation:
Let's examine each statement given and determine if it is correct or not correct based in the information given to in the graph.
Statement A: "The point (2, 100) means that there are 100 pounds of wild rice in 2 bags."
✅This is CORRECT because from the graph, on the x-axis (number of bags), when x = 2, y on the y-axis (pounds of wild rice) is 100.
Statement B: "The data represents a proportional relationship".
✅This is CORRECT because a graph that shows a proportional relationship between x and y, has a line that cuts through the point of origin (0, 0).
Statement C: "The equation x = 50y represents this situation".
❌This is NOT CORRECT. The equation does not represent a proportional relationship between x and y. The correct equation should be y = 50x. Where 50 is the constant of proportionality. That is y/x.
Statement D: "The constant of proportionality is 50."
✅this is CORRECT because constant of proportionality = y/x = 100/2 = 50.
You will need to give at least 2 values to plug in to solve the equation.
However, to solve for a single variable, you need to isolate it.
See picture taken as in how to solve for one variable.
Answer: $1125
Step-by-step explanation: 7500 x 3%= 225 Then multiply 225 by the 5 years. You will then get 1125. Marsha earned $1,125 in interest.
I hoped this helped, have a great rest of your day!
Answer:
The area of one slice of pizza is 18 in²
Step-by-step explanation:
First we have to know that the 360 ° representing the circle expressed in radians are expressed as 2π
Now we must calculate the area of the circle
a = π * r²
a = π * (12in)²
a = 144π in²
Now that we have the area of the circumference we multiply it by (π/4) / (2π)
144π in² * (π/4) / (2π) =
144 in² * 1/8 =
18 in²
The area of one slice of pizza is 18 in²
