1/5 of the tank is filled in 1/4 of a minute.
There are 4 periods of 1/4 minute in a minute, because 4(1/4) = 1.
That means that 4(1/5) = the rate, so the rate is 4/5 of a gallon per minute.
Amount of dresses you could make with material and how many marbles can fit into a container.
Answer: 9/4a^2|b^3|c^4
Step-by-step explanation:
81/16
Square root(81) = 9
Square root(16) = 4
9/4
Since 4 is the index of the radical, all of the exponents divide by 4
(index 4)a^8 = a^2
(index 4)b^12 = b^3
(index 4)c^16 = c^4
Now put the variables together to get the answer:
9/4a^2|b^3|c^4
