A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$70. A season ski pass costs ​$300. The
MatroZZZ [7]

The number of days when the season pass would be less expensive than the daily pass is 5 days.

<h3>How many days would the season pass be less expensive?</h3>

The equation that represents the total cost of skiing with the daily pass : (daily pass x number of days) + (cost of renting skis x number of days)

$70d + $20d = $90d

The equation that represents the total cost of skiing with the seasonal pass : cost of season pass + (cost of renting skis x number of days)

$300 + $20d

When the season pass becomes less expensive, the inequality equation is:

Daily pass > season pass

$90d > $300 + $20d

In order to determine the value of d, take the following steps:

Combine and add similar terms: $90d - $20d > $300

70d > $300

Divide both sides by 70 d > $300 / 70

d > 4.3 days

Approximately 5 days.

∠1 and ∠2 form a straight angle. ∠1 has a measure of 28°.<br> What is the measure of ∠2? PLZ HELP
Natalka [10]

Answer:

∠2 = 152

Step-by-step explanation:

A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.

That means that 180-28, will give us our other angle.

Amayo943,

Remember that with exponents you have to multiply the number of exponets by the same number it's in for example: 1^2 = 1 \times 1 In this case you need to know that:

  • 15^2 = 15 \times 15
  • 15 \times 15 = 225
  • =225

Therefore your answer is "225."

Hope this helps!
