So what you would do in this equation is since it is 10 pennies in each stack and she has 50 stacks all you have to do 10 times 50 which equals 500 and since there are 100 pennies in a dollar you divide 500 by 100 which would get you five.
Answer:
Five dollars
And 500 pennies
3r + 3s = 3(r + s) answer
You get 0.4 cups per dollar at the farm.

Answer:
10 meters
Step-by-step explanation:
You recognize that the ratio of leg lengths of the right triangle involved is ...
6 : 8 = 3 : 4
You know that any right triangle with leg lengths 3 and 4 has a hypotenuse of 5. The ladder will need to be in the same ratio:
3 : 4 : 5 = 6 : 8 : 10
The ladder needs to be 10 meters long.
_____
In case you don't remember that (3, 4, 5) is a "Pythagorean triple," you can figure the length using the Pythagorean theorem.
6^2 +8^2 = hypotenuse^2
36 +64 = 100 = hypotenuse^2
hypotenuse = √100 = 10 . . . . required ladder length in meters
