A skier is trying to decide whether or not to buy a season ski pass. a daily pass is $75. A season ski pass is $350. The skier w

pishuonlain [190]

Since the skier has to rent skis for 30 dollars per day with both passes, we can ignore it while solving the question.

A season pass is 350, while a daily pass is 75.

$\frac{350}{75} = \frac{25\times 14}{25\times 3} = \frac{14}{3} = 4 \frac{2}{3}$

So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.

So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.

A sphere with a radius of 4.8 centimeters is carved out of a right cone with a base radius of 8 centimeters and a height of 15 c

emmainna [20.7K]

Volume of the cone = 1/3 pi r^2 h = 1005.31 cm^3

Volume of the sphere = 4/3 pi r^3 = 463.25 cm^3

Volume of remaining portion of the cone = 1005.31 - 463.25

= 542.1 cm^3 to nearest tenth

What is the solution to this system of equations?<br>x-2y=15<br>2x + 4y=-18

jeyben [28]

Answer:

x = 3; y = -6

Step-by-step explanation:

x - 2y = 15

2x + 4y = -18

Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.

2x - 4y = 30

(+) 2x + 4y = -18

---------------------------

4x = 12

4x/4 = 12/4

x = 3

Now we substitute 3 for x in the first equation and solve for y.

x - 2y = 15

3 - 2y = 15

-2y = 12

y = -6

Answer: x = 3; y = -6

Determine the vertical asymptote for the rational function f of x equals quantity x minus 4 end quantity divided by quantity 3 t

Anastasy [175]

Answer:

vertical asymotote at $x=\frac{-2}{3}$

Step-by-step explanation:

$f(x)= \frac{x-4}{3x+2}$

vertical asymptote is the line where the graph goes close to the line but does not cross it.

To find vertical asymptote, we set the denominator =0 and solve for x

denominator is 3x+2

set 3x+2=0

Subtract 2 on both sides

$3x=-2$

divide both sides by 3

$x=\frac{-2}{3}$

vertical asymotote at $x=\frac{-2}{3}$
