I hope this helps you



1.k^2+5k-6=0


a=1


b=5


c= -6


disctirminant =b^2-4ac


disctirminant =5^2-4.1. (-6)


disctirminant =49


x1= -(5)+ square root of 49/2.1



x1=-5+7/2


x1=1



x2= -5- square root of 49/2.1


x2= -5-7/2


x2= -6

cluponka [151]

Answer:

V = 211.56 mm

Step-by-step explanation:

The volume of a pyramid :

V = 1/3(Lenght * width * height)

Length = 9mm

Width = 8.2 mm

Height = 8.6 mm

Hence, we have ;

V = 1/3(9 * 8.2 * 8.6)

V = 1/3 * 634.68

V = 211.56 mm

Percentage of the area shaded = 55%

Solution:

Perimeter of the square = 40 cm

Each side of the square = \frac{40}{4} = 10 cm

Area of the square = \text{side}^2

                               = 10²

                               = 100

Total area of the square = 100 cm²

The unshaded portion is two triangles.

Base of the smaller triangle = 10 cm – 7 cm = 3 cm

Height of the smaller triangle = 10 cm

Area of the smaller triangle = \frac{1}{2}\times \text{base}\times \text{height}

                                              $=\frac{1}{2}\times 3\times 10

Area of the smaller triangle = 15 cm²

Base of the larger triangle = 10 cm – 4 cm = 6 cm

Height of the larger triangle = 10 cm

Area of the larger triangle = \frac{1}{2}\times \text{base}\times \text{height}

                                              $=\frac{1}{2}\times 6\times 10

Area of the larger triangle = 30 cm²

Area of the shaded portion = Area of the square – Area of the smaller

                                                   triangle – Area of the larger triangle

                                              = 100 cm² – 15 cm² – 30 cm²

Area of the shaded portion = 55 cm²

Percentage of the area shaded = \frac{\text{Area of the shaded portion}}{\text{Total area of the square}}\times100\%

                                                    $=\frac{55}{100}\times100\%

Percentage of the area shaded = 55%
