10lb. of jam needs 5lb. apple, or 2lb. of jam needs 1lb. apple.
Now we want 8lb. of jam.
Set up a proportion:
2/1=8/x
Solve for x by cross-multiplying.
2x=8
x=4 lb. of apple
Answer:
314 inches³
Step-by-step explanation:
The area of a cone is πr²h/3. We need to find the height and radius of the cone. The height is 12 inches. radius * 2 = diameter.
Radius * 2 = Diameter
/2 /2
Radius = 1/2* Diameter
Radius = 5 inches
We substitute it in:
3.14 * 5² * 12/3:
3.14*25*4
314 inches³
Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.
