Answer:
160 off 20p coins
Step-by-step explanation:
- 1 p, 20 p, 5 p coins
- 1 p= 3/8 of the bag
- 5 p= 1 p= 3/8 of the bag
20 p coins= 640 - 640*(3/8+3/8)= 640*(1- 6/8)= 640 * 2/8= 640* 1/4= 160
Volume = area of base x height
area of base = volume/height = 210/14 = 15 ft^2
Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
