Answer:
1.49283
Step-by-step explanation:
8.1% as a decimal is 0.081
The product of that and 18.43 is ...
0.081 × 18.43 = 1.49283
__
If this is a monetary value, it would round to 1.49.
Well, we have linear terms (the heights and radii of the two cylinders) and cubic terms (the volume of the two cylinders). So, we need to cube the given ratio respective of their order.
2 -> to the power of 3 -> 2×2×2=8
3 -> to the power of 3 -> 3×3×3=27
Therefore, the ratio of the volumes of the two cylinders is 8:27. Your answer is D.
Answer:
1.90 hours
Step-by-step explanation:
We need to first find the unit rate, the number of minutes taken to fill 1 gallon.
It is given, 2.87 gallons per 1 minute, to get "how long" it will take to fill up 1 gallon, we have to divide the number of minutes (1) by the number of gallons (2.87).
So,
1/2.87 = 0.3484 minutes per gallon
Now, we need the time it will take to fill 328 gallons. We simply multiply 328 by the unit rate found (0.3484). We have:
328 * 0.3484 = 114.2857 minutes
We need the answer in hours, so we divide by 60:
114.2857/60 = 1.90 hours
