Answer:

r= ^7√2-1

Step-by-step explanation:

2=(1+r)^7

2=1^7 +r^7 ( 1 to the power anything is 1)

2=1+r^7

1+r^7=2

r^7=2-1

7^√r^7= ^7√2-1

r= ^7√2-1

What is the approximate volume of a cone with a height of 6 mm and radius of 18 mm?
Rudik [331]

Answer:

v = 2034.72 mm³

Step-by-step explanation:

radius = 18mm

height = 6mm

pi = 3.14

v = πr²h/3

v = 3.14 * (18mm)² x 6mm/3

v = 3.14 * 324mm²  x 2mm

v = 2034.72 mm³

The design for a mural is 16 in. Wide and 9 in. High. What are the dimensions of the largest possible complete mural that can be
Alexandra [31]

Answer:

Largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.

Step-by-step explanation:

Design of a mural is 16 in. wide and 9 in. high.

Dimensions of the wall are 24 ft by 14 ft.

If we enlarge the size of the design along the width the wall, scale factor to be used,

Scale factor = \frac{\text{Width of the wall}}{\text{Width of the design}}

                    = \frac{24}{16}

                    = \frac{3}{2}

With the same scale factor, height of the design will be,

\frac{3}{2}=\frac{\text{Height of the wall used}}{\text{Height of the design}}

\frac{3}{2}=\frac{\text{Height of the wall used}}{9}

Width of the wall used = \frac{3\times 9}{2}

                                     = 13.5 ft

Therefore, largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.
