Answer:

Area of one face of a cube = 81 sq cm.

Hence, each side of the cube = 81^0.5 = 9 cm.

So volume of the cube = 9^3 = 729 cm^3

Step-by-step explanation:

Step-by-step explanation:

Area of face of a cube = 81 cm squared

So area of face = a x a = 81

A^2 = 81

A= 9

So side = 9cm

So volume of a cube = side x side x side = side ^3

= 9x 9 x9 = 729

So Volume = 729 cm^3

STATISTICS The most familiar statistical measure is the arithmetic mean, or average. A second important statistical measure is t
NISA [10]

The absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

The minimum score that is within one standard deviation of the mean is of 15.6.

<h3>What is the absolute value function?</h3>

The absolute value function is defined by:

  • |x| = x, x >= 0.
  • |x| = x, x < 0.

It measures the distance of a point x to the origin of x = 0.

One standard deviation is of 5.3, while the mean is of 20.9, hence the absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

Which means that the minimum score is:

x - 20.9 = -5.3

x = 15.6.

In the diagram, the radius is 7 and tangent AB has length of 24. Determine the length of OA rounded to the nearest whole number
katen-ka-za [31]

Given the radius r and the tangent line AB, the length of the line OA is 24 units

<h3>How to determine the length OA?</h3>

The radius r and the tangent line AB meet at a right angle.

By Pythagoras theorem, we have:

AB² = OA² + r²

So, we have:

24² = OA² + 7²

Rewrite as:

OA² = 24² - 7²

Evaluate

OA² = 527

Take the square root of both sides

OA = 23

Hence, the length of OA is 24 units
