Grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height. how high

bezimeni [28]

Given that grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height.

So if D is the diameter and h is the height of the conical pile then we can write:

D=3h

We know that diameter = 2r, where r is the radius

2r=3h

$r=\frac{3h}{2}$

Volume of conical pile is given by formula

$V=\frac{1}{3}\pi r^2h$

Given that volume is 1110 cubic feet.

Now plug the values of Volume and r into equation of volume

$1110=\frac{1}{3}\pi (\frac{3h}{2})^2h$

$1110=\frac{1}{3}\pi\cdot\frac{9h^2}{4}\cdot h$

$1110=\pi\cdot\frac{3h^3}{4}$

$1110\cdot\frac{4}{3\pi}=h^3$

$471.098631552=h^3$

take cube root of both sides

7.78103342467=h

Hence height is approx 7.78 feet.

Find the range from 4 to -2 A. 2 B. 4 C. 6 D.-2

Scilla [17]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ The range is the highest value minus the smallest value

Therefore, you just need to subtract the two values to find the values:

-2 - 4 = -6

The difference is just 6, so your answer is C. 6

The sales tax for an item was $23.40 and it cost $390 before tax.<br> Find the sales tax rate.

tatyana61 [14]

$\huge \bf༆ Answer ༄$

Sales tax on the item is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \$23.40$

Cost of the item is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \$390$

sale tax rate is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{ \$23.40}{ \$390} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: 0.06 \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: 6 \%$

Therefore, the sales tax rate is 6 %
