What is 3640 rounded to the nearest hundred

The number of visits for which they will earn the same money is: 20 visits

How to solve Algebra word problems?

We are told to denote the number of visits by v.

Now, we are told that:

Fitness center A charges $50 plus $2 per visit. Thus, the equation to find the amount for v number of visits is:

2v + 50

Now, we are told that another fitness center B charges $30 plus $3 per visit. Thus, the equation to find the amount for v number of visits is:

3v + 30

Thus, the number of visits for which they will earn the same money is:

2v + 50 = 3v + 30

3v - 2v = 50 - 30

v = 20 visits

Answer:

• concave quadrilateral
• kite

Step-by-step explanation:

The attached figure shows several kinds of quadrilaterals. The sum of angles of a quadrilateral is 360°. A pair of sides will be parallel if the sum of consecutive angles between them is 180°.

Choices

Trapezium/Trapezoid

By definition, a trapezium/trapezoid has exactly one pair of parallel sides.

Concave quadrilateral

This is a quadrilateral with a reflex angle (one that measures more than 180°). Such an angle demands that no consecutive pair of internal angles have a total of 180°. Hence no two sides can be parallel.

Convex quadrilateral

If a simple quadrilateral is not concave, it is convex. Since the sum of angles is 360°, there exists the possibility for at least one adjacent pair of angles to total 180°. That would make at least one pair of sides be parallel.

In the attached figure, all of the quadrilaterals shown, except the "dart" at upper left, are convex quadrilaterals. Most of them, except the "kite" at lower left, have at least one pair of parallel sides.

There is no assurance that a convex quadrilateral will have no parallel sides.

Kite

A kite has two pairs of congruent adjacent sides. It cannot have any parallel sides.

Rhombus

A rhombus has all four sides of equal length. It is a parallelogram with two pairs of parallel sides.

No Parallel Sides

The two figures on the list that have no pairs of parallel sides are ...

• concave quadrilateral
• kite

These are shown in the left column of the attached figure.

Answer:

3, 1.03, 0.9, 6, 0, 15/4, -1 1/2, 0.01, 7, -2 (because also satisfies equal), 2, 9/10, 3.01, 2.97, -1, 0.0001, 2 1/5, 5/2, 4, -4/3, 5, 7/3, 1

Step-by-step explanation:

The inequality means that x is greater than or equal to -2. So, we can select all of the values that satisfy that.

Answer:

3, 1,03, 0,9, 6, 0, 15-4, -1 1-2, 0,01, 7, -2, 2, 9-10, 3,01, 2,97, -1, 0.0001, 2 1-5, 4, -4-3, 5, 7-3, 1
