Answer:
5% loss
Step-by-step explanation:
2000 is the cost price of the shopkeeper. This is after a 20% discount, so the before-discount price would be:
20% reduced of what number is 2000?
We let that price be x, so we can write an equation and solve:
x - 20% of x = 2000
Note: 20% = 20/100 = 0.2
So,
x - 0.2x = 2000
0.8x = 2000
x = 2000/0.8
x = 2500
Now, if he were to sell for 600 less, that would be:
2500 - 600 = 1900
That would be a 2000 - 1900 = 100 LOSS
To find as a percentage, we use the formula:
Where
New = 1900
Old = 2000 (original cost)
Substituting, we find the percentage:
So, that's a 5% loss
Around the outside of a circle measures 360°. If arc ADB measures 250°, then arc AB measures 360-250 which is 110°. Because point C is the center of the circle, then angle ACB is a central angle. By definition of an arc intercepted by an angle, they are the exact same measure in degrees. So if arc AB = 110, then the measure of the angle ACB also measures 110.
Nearest thousand would be 300,000

The major math strands for a sixth grade curriculum are number sense and operations, algebra, geometry and spatial sense, measurement, and functions and probability. While these math strands might surprise you, they cover the basics of what a sixth grader should learn in math.
Students in 6th grade should already master math facts to help them understand more advanced math concepts. Some of the skills you should ensure mastery on for 6th graders include:
Multiplying 3-digit by 2-digit numbers
Comparing, rounding, and performing basic operations with decimals
Fractions: adding, subtracting, simplifying, comparing, etc.
Data analysis using bar graphs, line graphs, Venn diagrams, etc.
Geometry: using a protractor, sorting and classifying triangles, polygons, quadrilaterals

Math Objectives for 6th Grade
At the beginning of the school year you should define some 6th grade math goals and objectives for your student. Below is a general idea of the 6th grade math objectives your child should be working towards.
Understand pre-algebra concepts such as using variables to simplify expressions
Identify decimal place value; compare and order decimals using a number line
Use frequency tables and identify appropriate intervals
Know how to use ratios and rates to compare data
Locate and plot points on a coordinate graph using ordered pairs
Understand the relationship between fractions, decimals, and percents
Also tell what you need that needs to be simplified. Be specific.
