A department store buys 300 shirts at a cost of $1,800 and sell them for $10 each. Find the percent markup rounded to the nearest percent.
The percent markup of the department store is given as follows:
67%.
How to obtain the percent markup?The percent markup is obtained applying the proportions in the context of this problem.
A department store buys 300 shirts at a cost of $1,800, hence the cost per shirt is given as follows:
1800/300 = $6.
The shirts are sold by $10, hence the markup is given as follows:
10 - 6 = $4.
The percent markup is given by the division of the markup by the initial price and multiplied by 100%, hence:
4/6 x 100% = 67%.
(rounded to the nearest percent).

3x*2 -10x +7/ x +4 which of the following shows the division problem in synthetic division form?
We can write the given expression (3x² - 10x + 7/ x + 4) in synthetic form as :
- 4 |3 -10 7
What is Synthetic Division?In algebra, the synthetic division is one of the methods used to manually perform the Euclidean division of polynomials. The division of polynomials can also be done using the long division method. But, in comparison to the long division method of polynomials, the synthetic division requires lesser writing and fewer calculations. That means the synthetic division is the shorter method of the traditional long-division of a polynomial for the special cases when dividing by a linear factor.Given is the expression as -
(3x² - 10x + 7/ x + 4)
We can write the given expression in synthetic form as -
- 4 |3 -10 7
Therefore, we can write the given expression (3x² - 10x + 7/ x + 4) in synthetic form as :
- 4 |3 -10 7

On solving the provided question, we can say that sum of all angles of a triangle is 180, angle 1 = 103, angle 2 = 47 and angle 3 = 22
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

Where is 0 latitude and 0 longitude?
0 degree latitude and 0 degree longitude is at equator
Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.
Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.
What is the uses of latitude?
Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.
The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude.

∆ABC and ∆EFD are congruent by the ASA criterion as segment AC and segment DE has single tick mark, angle A and angle E has single tick marks on arc and angle C and angle D has double tick marks on arc.
The ASA (Angle-Side-Angle) criterion states that if two triangles have two angles and the included side congruent (identical), then the two triangles are congruent.
In this case, both triangles ABC and DEF have two angles congruent (angle A and angle E, and angle C and angle D), and the included side (segment AC and segment DE) congruent. Therefore, by the ASA criterion, the two triangles ABC and DEF are congruent.
To be more precise Angle A and angle E has single tick marks on arc which means both angles are congruent and angle C and angle D has double tick marks on arc which means both angles are congruent. As we know, if two triangles have corresponding parts congruent, the two triangles are congruent.
If segment BC equals to segment FD we can prove that the triangles, ∆ABC and ∆EFD are congruent by the SAS criterion.

The loan that offers the best effective annual rate is loan N (option c)
What loan that offers the best effective annual rate?The effective annual rate is the actual interest rate that is earned on an investment after accounting for the number of compounding.
Effective annual rate = (1 + APR / m ) ^m - 1

Effective annual rate for loan L = (1 + 0.08254/365)^365 - 1=0.08603 = 8.603%
Effective annual rate for loan M = (1 + 0.08474/52)^52 - 1= 0.08836 = 8.836%
Effective annual rate for loan N = (1 + 0.08533/12)^12 - 1= 0.08875 = 8.875%
