Rational numbers are positive and negative numbers that can be said or seen fully (ex. 5 or 2.391); unlike irrational numbers that go on forever like pi.

Integers are negative and positive whole numbers, that do not include fractions or decimals. (ex. -1, 0, 50, -230)

10. Suppose you earn $7.25 per hour working part-time for a florist. What is the minimum number of hours you must work to earn a
UNO [17]
To make it like a simple, I'll make an equation. Let x be the number of hours because x represents unknown and we don't know the hours. Then your per hour is $7.25 right? so it would be x7.25. You want to know how many hours you will work so you can earn $125. The equation is simple as this x7.25 = 125.
All you have to do is divide the equation by 7.25 because that's your per hour.
It will look like this, <u>x7.25</u> = <u>125</u>   then the answer would be 17.24 hours. 
                                   7.25   7.25

Find all of the points of the form (x, −x) which are 7 units from the origin.
Morgarella [4.7K]

Answer:

  • (-7, 0) and (7, 0)

Step-by-step explanation:

<u>All the points that are 7 units from the origin are on the circle:</u>

  • x² + y² = 7²

<u>The maximum and minimum values of x obtained when y = 0:</u>

  • x² = 7²
  • √x² = √7²
  • x = ± 7

So

  • min x = -7 and
  • max x = 7

<u>The points are:</u>

  • (-7, 0) and (7, 0)

How would I go about solving this?
garik1379 [7]
If you draw more of those triangles, there will be 6 that can fit, so find area of 1 triangle and multiply it by 6. Write that number down and then do Pi r squared to find the area of the circle, then do circle area minus triangles area when you get that, divide it by 6. That is the area of the white region so then do Pi R squared again and then subtract the white area from that
