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.

Enter and solve a polynomial equation for the situation described.
klasskru [66]

Height = x (This is given)

Length = 5x

Width = 6x

Volume = length × width × height

The equation will be: (5x)(6x)(x) = 1920

simplify:

30x² × (x) = 1920

30x³ = 1920

Divide both sides by 30

x³= 64

x = ∛64

x= 4

If x = height, then, the height is 4cm

5x = length

20cm = length

6x = width

24cm = width

Between July 28 and 30 of last year over 41.2 cm​ (about 16 ​inches) of rain fell in a city. The normal total monthly rainfall i
ZanzabumX [31]

The amount more of rain that fell in those three days than normally falls in July and August combined was 31.19 cm.

<h3>How much more rain fell in those three days?</h3>

The amount of rain in those three days was 41.2 cm.

The combined normal rain July and August is:

= 6.36 + 3.65

= 10.01 cm

The difference is therefore:

= 41.2 - 10.01

= 31.19 cm
