I need answers and explanation with ratios to help my daughter with homework
Leviafan [203]

Using proportions, it is found that:

2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.

3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

For each of Alan and Bree, we have to find the proportions of words typed per second and mistakes per second.

Then, for Alan:

  • Words typed per second: 5/6 = 0.83.
  • Mistakes per second: 2/6 = 0.33.

For Bree:

  • Words typed per second: 9/8 = 1.13.
  • Mistakes per second: 3/8 = 0.375.


Then:

2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.

3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.

Classify the system as independent, dependent, or inconsistent.
Anastasy [175]
1. 4x + 8y = 12....divide by 4
     x + 2y = 3
     2y = -x + 3
     y = -1/2x + 3/2...slope is -1/2, y int is 3/2
 
     x + 2y = -3
     2y = -x - 3
     y = -1/2x - 3/2...slope is -1/2 and y int is -3/2

when the slopes are the same, and the y int are different, then the lines are parallel and never intersect...so they have no solution and are inconsistent
=================
2. y = 2x - 1...slope is 2 and y int is -1
    y = -2x + 5 ...slope is -2 and y int is 5
when the slopes are different and the y int are different, then there is 1 solution making it independent
=================
3. 4x - 12y = 8...divide by 4
     x - 3y = 2
same as other equation meaning the equations are the same line...meaning they have infinite solutions making them dependent
