Answer:
$14.93
Step-by-step explanation:
If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.
Total cost=circumference* cost per inch
Circumference of a circle is given by
Where r is radius. Substituting 4.75 inch for r then
Cost=29.86*0.50=$14.93
Answer:
x > 9/10 is the answer to the equation.
Step-by-step explanation:
3x -2(x -1) > 11-9x
3x -2x +2 > 11-9x
x+2> 11-9x
x+9x > 11-2
10x > 9
x > 9/10
Answer:
There are three more square chocolates left
Step-by-step explanation:
We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)
To determine whether they used the same number of tiles, set the two expressions equal to each other and solve for x. Is there a solution for x? Why or why not? If there is a solution, what is it?
5x +2 = 5x + 5 (subtract 5x and 2 on both sides)
0 = 3 No solution
How could you change the equation so it has infinitely many solutions?
Have 2 or 5 change because they need to be equal to each other. Its fine what you put as long as the equal sign is the same as the other side like 3 = 3 for example or 5 = 5, something like that. Once they have the same end then you can substitute the number to x.
What would infinitely many solutions mean in terms of the situation?
x represents the number of tiles they used
