Professor Harrington is grading papers in the teachers' lounge. She has already finished grading 10 assignments, and is grading 5 more assignments per hour. Her teaching assistant just came in to help her. She can grade at a rate of 10 assignments every hour. At some point, they will be finished and will have graded the same number of papers. How many assignments will they each have graded? How long will that take?

Answer bp

pzz, entre las tareas y el tiempo no especifica mucho pero si en tiempo refieres alas hora tardada para que los 2 profesores tengan las misma candatidad de tareas serian de 2 horas

Step-by-step explanation:

Since subject 1 scores 5 tasks per hour and subject 2 10 tasks per hour taking into account subject one, it takes 4 hours to reach 20 tasks and subject 2.2 hours to have 20

answer: -2+√x,-2-√x

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
