Is 7/8 or 11/10 closer to 1 whole and why

Answers


11/10 is closer because the bigger the denamorator  is the smaller the pieces are, and 10 is bigger than 8 also 11/10 might be over 1 but it is still closer.

Answer:

(7x + 7)/((x-3)(x+4))

Excluded values are 3 and -4

Step-by-step explanation:

To simplify the expression multiply to create a common denominator.

Multiply the first fraction by (x-3) and the second fraction by (x+4).

(3)/(x+4) + (4)/(x-3)\n\n(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4))

(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4)) \n\n(3(x-3) + 4(x+4))/((x-3)(x+4))\n\n(3x - 9 + 4x + 16)/((x-3)(x+4))\n\n(7x + 7)/((x-3)(x+4))

Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.

What is the approximate volume of a cone with a height of 6 mm and radius of 18 mm? Use 3.14 to approximate pi, and express your final answer to the nearest tenth.

Answers

Given:
radius = 18mm
height = 6mm
pi = 3.14

volume of a cone is computed by multiplying pi, radius raised to the 2nd power, and height, which has been divided by 3.

v = πr²h/3

v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm²  x 2mm
v = 2034.72 mm³

volume rounded to the nearest tenth would be 2034.70 mm³

Answer

V = 2034.72 mm³
