Answer:

<h3>D.  p2 + 27p > 770</h3>

Step-by-step explanation:

Ms. Winter wants to have 27 more rows than people in each row.

The number of people in each row is represented by p.

The number of rows is represented by p + 27.

Ms. Winter wants to have more than 770 people in the march.

To find the total number of people in the march, find the product of the rows and the people in each row.

Set up an inequality to represent the situation.

p(p + 27) > 770

p2 + 27p > 770

Suppose that m∠MKN = 55°. What is m∠MCN?<br> !please no absurd answers!
Elena L [17]

Answer:

angle M and N are right angles

we can draw a line joining M and N  

so we’d have a triangle MNC AND KMN

both MNC AND KMN BECOME ISOSCELES TRIANGLES

so since we have 55 degrees for angle MKN. We have to find the other 2

180-55=125

now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN

now to find the sides of triangle MNC

90-62.5= 27.5

27.5*2= 55

180-55=125=angle C

(sorry, it’s complex)

Simplification of polynomials.

Polynomials <em>are</em> mathematical expressions made up of many terms.<em>To</em> simplify a polynomial <em>the most, you must collect all</em><em> </em>like terms <em>and rearrange them from highest to lowest power.</em>

A FEW MATH QUESTIONS ! PLEASE EXPLAIN ANSWERS ! (:
7nadin3 [17]

answers

1) 70

2) 3,840

3) 24

4) 72


<u>Explanation</u>

Q1

The surface area of a cone is given by;

S.A = 2Πrl + Πr²

Where r is the radius of the base and l is the lateral height.

Πr² = area of the base = 20 in²

2Πrl = Area of the lateral surface

         = 2.5 × 20

          = 50

Area of the cone = 50 + 20

                            = 70 in²

Q2

The sides of the Pythagorean triangle with legs of 12 and 16.

The 3rd side will be;

c = √(12² + 16²)

  = √400 = 20

Volume = 12 × 16 × 20

              = 3,840

Q3

The volume of a cone is given by;

volume = 1/3 Π r² h

This shows that the volume of a cone is a third the volume of the cylinder.

∴ Volume of the cylinder = 12 × 3

                                            = 24 ft³

Q4

The volume of any regular figure is;

Volume = base area × height

When the dimensions area usually 3. Let these dimensions be x, y and z.

∴ volume  = x × y × z = 9

  Doubling the dimensions;

Volume = 2x × 2y × 2z = 2 × 2 × 2 × 9

             = 8 × xyz = 8 × 9

             = 72 ft²
