Answer:
the Larger poster is 9ft long by 6ft wide
Step-by-step explanation:
In order to find the length and width values of the large poster we first need to find the width of the smaller poster since we are already given the length. Since we are also provided with the perimeter we can add the length twice and subtract it from the perimeter which would give us the value of both width sides of the rectangle, then we simply divide by 2 to get the value of the individual width.
10ft = 3ft + 3ft + w + w
10ft = 6ft + 2w
4ft = 2w
2ft = w
Since the larger poster is 3 times as big for the length and the width we simply multiply the smaller poster's length and width by 3...
L = 3 * 3 = 9ft
W = 2 * 3 = 6ft
Finally, we can see that the Larger poster is 9ft long by 6ft wide

By the way, Google has a built in calculator. You can just type in "321.5 kmph in mph" and it will come up with this answer.
You could also use the fact that

,
According to the properties of equality, if you have two equal expressions and you change them in the same way, the results wil also be equal.
So that means we can multiply each side by 321.5 and get our answer above.
You just take the number of the color of interest (green) and divide by total marbles
9/35 = 0.257 ~~ 25.7%

Answer:
The slinky situation
Step-by-step explanation:
To make a rate, divide one value by the other.
For the short bungee,
6 inches ÷ 3 pound = 2 inches per pound
While the slinky,
36 inches (remember to convert feet to inches) ÷ 1 pound = 36 inches per pound
As you can tell by the numbers, 36 inches per pound is way better than the 2 inches per pound.
