The answer is 216 cubic feet. How? All you have to do is multiply every number then divide it by 2. Like this: 2*12*18=432. 432/2= 216 cubic feet.
When the dept of the water is 3/5 of the height of the cone, the radius of the water's surface is 3/5 of the radius of the cone: 1.2 ft. The rate of change of depth is equal to the rate of change of volume divided by the area of the surface:
dh/dt = (dV/dt)/A = (dV/dt)/(π·r²)
= (3/2 ft³/s)/(π·(1.2 ft)²)
= 25/(24π) ft/s ≈ 0.3316 ft/s
Answer:
Debbie's opportunity cost of attending college for the year is $42,000.
Step-by-step explanation:
Debbie quits her job, which pays $30,000 a year, to finish her college degree.
Her annual college expenses are $10,000 for tuition, $2,000 for books, and $700 for food.
So, her opportunity cost will include the amount of salary she could have earned if she continued working plus the cost of tuition plus the cost of books:
dollars
Therefore, Debbie's opportunity cost of attending college for the year is $42,000.
You didn't clarify what the angle is needed for, but still, I'd say never.
If you know two sides of a right triangle you can always find the third using the pythagorean theorem.
Once all sides are known, you can find the three angles: one is surely right, since you have a right triangle. The other two can be found using the sine law.
