Answer: The quick way is to square the half of it.
Step-by-step explanation: You divide your main number by 2 and figure out that half. If it is still too big, divide by 2 again. If you need to keep repeating that is fine. Thank you multiply your answer by however many times you divided by 2.
Answer:
4.06 = 4
Step-by-step explanation:
The total amount of little cubes on the surface is 600, since there is 100 cubes on one face and there are 6 faces (6 times 100). But, there is overlap because the cubes on the edges are painted on more than one edge. There are 12 edges, and every edge has 10 that need to be subtracted. So that’s a total of 120 that need subtracting, and 600-120 is 480.
Answer: 12/13....Remember the shortcut SOH CAH TOA ——> sin = opposite/hypotenuse, cos = adjacent/hypotenuse, and tan = opposite/adjacent...know that for this problem tells you that cos = 5/13 and tan = 12/5 so thus sin = 12/13 (opposite = numerator of tan, hypotenuse = denominator of cos)
4/10 is equal to 2/5 because if you reduce 4/10 you get 2/5 which shows that they are equal.
