1. Ebony's right eye....opposite of -1.50 = 1.50
2. the rational numbers are : -1.50, 1.50, -1.00, and 0.25....these are all rational because they can be turned into fractions.
3. least to greatest : -1.50, -1.00, 0.25, 1.50
4. not sure how to answer this...negatives are always less then positives....however, with negatives,unlike positives, the larger the number, the smaller it is.
1. A
I hope this helped! This is because the division of numbers and factors are equal to this.

Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
The discounted clock would be 6 dollars. I found this by creating a table with 3/3, 2/3, and 1/3 on one side and the 18 across from 3/3 since it is the regular price. To find 2/3 I think we should find 1/3 first. To find that we simply divide 18 by 3 since we are finding one third of 18. Luckily 3 evenly goes into 18 6 times. Now we aren’t done, that is 1/3 so we double the 1/3 which is 2/3 and we double the 6 which is 12. Now that we know how much those cost, it says 2/3 off. The regular price was 18 and 2/3 was 12 so 18-2/3 is 18-12 which equals 6. The discounted alarm clock is $6.00.
