Svetllana [295]

Answer:

Cost of 12 pencils = 37 4/5 = 189/5

Cost of 1 pencil = 189/5 ÷ 12

= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20

So required answer is 3 3/20

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x −

zloy xaker [14]

Answer:

Only one solution
(x, y) = (-0.8, -3.6)

Step-by-step explanation:

You know there is only one solution because the ratio of x- and y-coefficients is different in the two equations. That means the lines will have different slopes, so must intersect in exactly one point.

The y-coefficients are opposites, so you can eliminate the y-variable by adding the equations:

(2x -y) + (3x +y) = (2) + (-6)

5x = -4

x = -4/5 = -0.8

Substituting this into the second equation, we have ...

3(-0.8) +y = -6

y = -3.6 . . . . . . . add 2.4 to both sides

The solution is (x, y) = (-0.8, -3.6).

You can also find the solution by graphing (or using a graphing calculator).

A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decr

Elena L [17]

Answer:

$0.0727 cm\: per\: second$

Step-by-step explanation:

The Volume of the cylinder is constant

Volume of a cylinder, $V=\pi r^2h$

Given:

$\frac{dh}{dt}=0.8 cm/sec\\ r=2cm\\h=11cm\\\frac{dr}{dt}=?$

$\frac{dV}{dt}=\pi r^2 \frac{dh}{dt} + 2\pi r h\frac{dr}{dt}$

$0=\pi* 2^2*0.8 + 2\pi*2*11\frac{dr}{dt}\\0=3.2\pi+44\pi\frac{dr}{dt}\\44\pi\frac{dr}{dt}=-3.2\pi\\\frac{dr}{dt}=\frac{-3.2\pi}{44\pi} \\\frac{dr}{dt}=-0.0727 cm\: per\: second$

The radius is decreasing at a rate of $0.0727 cm\: per\: second$
