Answer: A = 21 units2
Step-by-step explanation: Please look at the picture below!
1 kilogram=1000 grams
divide both sides by 1000
1/1000 kilograms=1gram
5 grams=5 times 1/1000kilograms
5grams=5/1000kilograms=1/200kilograms
5grams= 5/1000kg=0.005kg
the answer is 0.005kg or 1/200kg

Answer:
9108
Step-by-step explanation:
23^3+(-12)^3+(-11)^3 remove parentheses
= 23^3-12^3-11^3 group difference of two cubes
= (23-12)(23^2+23*12+12^2) + 11^3 factor difference of two cubes
= 11 (23^2+23*12+12^2-11^2) factor ou 11
= 11(23(23+12) + (12+11)(12-11)) apply difference of two squares
= 11 (23*35+23*1) factor out 23
= 11(23*(35+1)) simplify
= 11*23*36 convert 11*23 into difference of 2 squares
= (17^2-6^2)*6^2 expand parentheses
= 102^2-36^2 evaluate squares
= 10404 - 1296 subtraction
= 9108

Answer: 18
Step-by-step explanation:
The probability of this event is 424=1/4. Then the probability of 5th toss is head is 1/2. Hence, in the end the answer is 14⋅12=18.
