Answer:
0.25 feet per minute
Step-by-step explanation:
Gravel is being dumped from a conveyor belt at a rate of 20 ft3/min. Since we are told that the shape formed is a cone, the rate of change of the volume of the cone.


Since base diameter = Height of the Cone
Radius of the Cone = h/2
Therefore,


Therefore: 
We want to determine how fast is the height of the pile is increasing when the pile is 10 feet high.

When the pile is 10 feet high, the height of the pile is increasing at a rate of 0.25 feet per minute
Answer: he will be able to make 19 full pieces
Step-by-step explanation:
1. Start off by making 7 feet into 84 inches so the measurements can match.
2. Add 4/14 inches and the 1/8 a inch together so you know how much is being taken off 84 inches. The amount will be 35/8 inches.
3. Divide 84 inches by 35/8 inches = 19 1/5
4. The whole number of the answer will be how many boards you can make from the board.
Multiply both sides by 2200/1760 * 2200/1760 and you get 1.25
Answer:
hello there,
the answer for this equation is:
The value of Start Fraction 6 Over x End Fraction + 2x2, when x = 3 is 20.
Step-by-step explanation:
:
Split the second term 7x^2 - 8x - 12 into two terms
7x^2 + 6x - 14x - 12
Factor out common terms in the first two terms, then in the last two terms
x(7x + 6) - 2(7x + 6)
Factor out the common term; 7x + 6
<u>(7x + 6)(x - 2) </u>
