katovenus [111]

Answer:

maximum 5 CDs

Step-by-step explanation:

Let Mitchell can order a maximum of x CDs

It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.

Thus, we have the total cost for x CDs

15.99x+9.99

Now, Mitchell has no more than $100 to spend. It means

15.99x+9.99

Subtract 9.99 to both sides

15.99x

Divide both sides by 15.99

x

Hence, Mitchell can order maximum 5 CDs

Draw a line between the points representing wicket 3 and wicket 9 on the diagram. Then, find the
zalisa [80]

Based on the calculations, the area of a rectangle to the nearest hundredth is equal to 1143.92 ft².

<h3>How to calculate the area of a triangle?</h3>

Mathematically, the area of a triangle can be calculated by using this formula:

Area = 1/2 × b × h

<u>Where:</u>

  • b represents the base area.
  • h represents the height.

By drawing a line between the points representing wicket 3 and wicket 9, we can logically deduce that wicket 2 forms a perpendicular bisector. Thus, the distance between the points representing wicket 3 and wicket 9 is given by:

Distance = 1/2 × 36.77

Distance = 36.77/2

Distance = 18.39 ft.

For the height of this triangle, we would apply Pythagorean's theorem:

h² = 25.02² - 18.39²

h² = 626.0004 - 338.1921

h² = 287.8083

h = √287.8083

h = 16.97 ft.

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × 36.77 × 16.97

Area of triangle = 311.99 ft².

For area of the rectangle, we have:

Mathematically, the area of a rectangle can be calculated by using this formula;

Area = LW

Area = 36.77 × 31.11

Area = 1143.92 ft².

Use expressions for odd integers to confirm the conjecture that the product for two odd integers is an odd integer.
Mandarinka [93]

k, n - integers  

2k+1  - an odd integer

2n+1  - another odd integer

The product of them:

  (2k + 1)(2n + 1) =

= 4kn + 2k + 2n + 1 =

= 2(2kn + k + n) + 1

The product of integers (2kn) is integer

and the sum of them (2kn+k+n) also is integer

So  (2k + 1)(2n + 1)  = 2(2kn + k + n) + 1  is an odd integer
