The length of each side = sqrt 200 m
By the pythagoras theorem
D^2 = sqrt(200)^2 + sqrt(200^2) = 200 + 200 = 400 (where D = diagonal)
D= sqrt400 = 20 m
The answer is B
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda <em>still</em> have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer:
The answer should be 18.
Step-by-step explanation:
Divide the numerator by the denominator: 23 ÷ 23 = 1
Add the number you got to the whole number: 17 + 1 = 18.
Therefore: 18 is your answer.
We have l = 20 * 20 * 20 = 8000 cm3
One cube will have l = 5 * 5 * 5 = 125 cm3
-> The maximum number of cubes that need to use to fill the container with water is 8000 / 125 = 64
