Briana bought a lot of snacks from Dollar General last night for $193.84, not including tax. If the tax rate was 9%, how much was her total? Pls explain I will make brainliest

Answers

I believe the total is $211.27.

After doing multiple searches on the internet, I believe that tax rate is a percentage of the product that is added to the total cost.

9 percent of 193.84 is 17.4456, which rounds up to 17.44, and 17.44 added to 193.84 is 211.27.

Please, if something isn't correct here, don't refrain to tell me, and I will correct my mistake. Thank you.

The answer is 211.27 Hope it helps!!!!

What is the approximate area of the trapezoid?

A. 27 square units
B. 29 square units
C. 30 square units
D. 36 square units

Answers

D.36. You count the squares inside

Approximate area of the given trapezoid is equals to 36 square units.

What is trapezium ?

"Trapezium is defined as the quadrilateral whose one pair of opposite sides are parallel to each other."

Formula used

Area of the trapezium = [tex]\frac{1}{2} (a +b) h[/tex]

[tex](a + b)[/tex] = Sum of the parallel sides

[tex]h =[/tex] perpendicular distance between the parallel sides

According to the question,

From the given diagram,

1 grid in the graph represent 1 unit

Length of parallel sides of given trapezium

Approximate length of Upper side of the trapezium = 3units

Approximate length of lower side of the trapezium = 9units

Approximate height of the trapezium = 6units

Substitute the value in the formula to get the area of the trapezium,

Area of the trapezium [tex]= \frac{1}{2} (3 + 9) (6)[/tex]

[tex]= 36[/tex] square units

Hence, Option(D) is the correct answer.

Answer:

A unique triangle means there is ONLY ONE WAY to create the triangle. All unique triangles are congruent (the same) even though you may have to “flip” or “turn” them to line up. Criteria For A Unique Triangle.

Once you find the value of your angle, subtract it from 180° to find the possible second angle. Add the new angle to the original angle. If their sum is less than 180°, you have two valid answers. If the sum is over 180°, then the second angle is not valid.

if they dont add up to 180 then they are no triangle

The height is the hardest to find for each, so to find which goes where youd need to find what's straighter.

Like the triangle, to find the height youd need to flip it around to see what measurement is the straightest.
