Scenario:
A stack of n small cups has a height, h, in centimeters of h=1.5n+6.
A stack of n large cups has a height, h, in centimeters of h=1.5n+9.

Using G00gle Draw, or by hand, graph the equations for each cup on the same set of axes. Make sure to label the axes and decide on an appropriate scale.

For what number of cups will the two stacks have the same height?

Answers

Answer:

The lines will never intersect.

Step-by-step explanation:

The slope of the cups is the same, 1.5.  The y-intercept of the small cups is 6

The y-intercept of the big cups is 9.

This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.

There are 15 girls in the class and 8 boys. Lauren says that the ratio of girls to boys is equivalent to 30 : 18. Is Lauren correct?

Answers

Answer:

No

Step-by-step explanation:

If 15 x 2=30 and 8x2=16 not 18 it’s incorrect

Answer:

No, Lauren is not correct because the ratio is actually 15:8 this is because the ratio represents the number of boys to girls. The only way to show this equation in ratio notation would to say 15:8. Therefore Lauren is incorrect.
