How to set the equations
Arisa [49]

Answer: a = Rectangular, b = 46.4 feet, c = 7 ft or 117 ft above ground level

<u>Step-by-step explanation:</u>

a) Use the rectangular coordinate system (x, y) and set the origin at the center of the ferris wheel.

b) The origin is at 62 feet from the ground.  The rider is 100 feet from the ground. So, the y-coordinate of the rider is 100 - 62 = 38.  Need to find the x-coordinate.

x² + y² = r²

x² + (38)² = (60)²

x² = 60² - 38²

x = 46.4 feet

c) The x-coordinate is given (24 ft) .  Need to find the y-coordinate.

x² + y² = r²

(24)² + y² = (60)²

y = 60² - 24²

y = +/- 55

Convert that to ground level:

62 + 55 = 117 feet above ground level

62 - 55 = 7 feet above ground level

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards
ICE Princess25 [194]

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

Initial = 150

<em />Additional = 10<em> (weekly)</em>

Sarah:

Initial = 233

Additional = 5 (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

Initial + Additional * w

So,

For Ryan, the expression is:

150 + 10 * w

150 + 10w

For Sarah, the expression is:

233 + 5 * w

233 + 5 w

To determine the number of weeks, we have to equate both equations:

150 + 10w= 233 + 5 w

Collect Like Terms

10w - 5w = 233 - 150

5w = 83

Solve for w

w = 83/5

w = 16.6

16.6 implies about 17 weeks, because 16.6 approximates to 17

<em>Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks</em>
