Answer:

23 children and 9 adults

p <= 70/9

Step-by-step explanation:

Let x = # of adults and y = # of children. The number of children is 5 more than twice the number of adults, so x = 2y + 5. The total cost of entrance is $6525, so 225x + 150y = 6525.

x = 2y + 5

225x + 150y = 6525

x - 2y = 5

225x + 150y = 6525

75x - 150y = 375

225x + 150y = 6525

300x = 6900

x = 23

x = 2y + 5

23 = 2y + 5

18 = 2y

y = 9

225p + 3750 <= 5500

225p <= 1750

p <= 70/9

Explain how you would name a sorting rule for square, rectangle, and triangle

Lapatulllka [165]

A closed convex polygon with 3 sides is called a triangle.

A closed convex polygon with 4 sides is called a quadrilateral.

If in a quadrilateral, two pairs of opposite sides are parallel, then it is a parallelogram.

If in a parallelogram, one of the angles is 90°, then it is a rectangle.

If in a parallelogram, all the four sides are equal, then it is called a rhombus.

If in a rhombus, the two diagonals are equal, then it is called a square.

We can frame the sorting rule as follows:

Polygon with 4 equal sides - Square, Rhombus

Polygon with 4 unequal sides - Parallelogram, Rectangle, Kite, Trapezium, Quadrilateral

Polygon with 3 equal sides - Equilateral triangle

Polygon with 3 unequal sides - Skalene triangle

etc.

frozen [14]

Answer:

The yield of this new bond is approx 3.8%.

Step-by-step explanation:

Given : Claribel has a $500 bond with a 4% coupon. Claribel purchased this bond for $525.

To find : What is the yield of this new bond?

Solution :

As coupon is 4 % , a $ 500 bond earns is given by,

$4\% \text{ of } 500= 0.04\times 500= $20$

A $ 500 bond earns $ 20 in a year.

Now as market price of bond is $ 525 , but it earns $ 20

The rate of interest earned is

$\frac{20\times 100}{525}= \frac{80}{21}=3.81\%$

Therefore, the yield of this new bond is approx 3.8%.
