Answer:
341
Step-by-step explanation:
- Plug the value of b in:
- 3(25) = 3 × 25 = 75
- Plug 75 in:
- = 75 ÷ 5 = 15
- Plug 15 in: 356 - 15
- 356 - 15 = 341
I hope this helps!
Answer:
Present value of contributions is $24,106.15
Step-by-step explanation:
Weekly rate=9%/52weeks= 0.173%
Weekly contributions $50
Number of weeks=20years×52weeks=1040
Present value of contribution=$50(1-[(1+9%/52)^-1040 /(9%/52)
Present value of contribution= $24,106.15
Given: 195 blueberries = 27 pounds
To find: How much Emily picked for her friends
Solve: Since 1 pound of blueberry is 195, Multiply 195 by 27
195 * 27 = 5265
Hence, Emily picked 5265 blueberries for her and her friends
First insight that is useful here is the fact that you can make a side of the fence any multiple of 2 feet, as long as it's at least 4. By taking 4 foot pieces, you can make 4,8,12, and so on. If you start with 6, then take 4 foot pieces, you can make 6,10,14 and so on. You don't need the 8 foot pieces, they're only a convenience.
So, suppose one side is the smallest possible, ie., 4 foot, what must the other side be to satisfy the constraint?
It must be greater than 216/4=54, so at least 56 (remember, only even sizes), and smaller than 480/4=120, so at most 118.
I've plotted all the possible widths and lengths, but there are a lot of them! (See picture, green area).
Selecting which fence sizes you need is possible using the fact that you can create any multiple of 2 starting at 4. I hope this gives you some pointers!
