Most likely centimetres, because metres are too big and millimetres are too small :)

Answer:

centimeter.

Step-by-step explanation:

Tennis balls are the balls which are usually designed top play the sport of tennis. They are usually of fluorescent yellow in color but it can be of any color.

The certain criteria is set for tennis balls for their weight, size, bounce and deformation and the regulation play approved this criteria. The official diameter of the tennis ball is 6.54–6.86 cm which set by the International Tennis Federation. And the mass of these tennis balls ranges from 56 g- 59.6 g.

Therefore, the radius of tennis balls is measured in centimeters.

scoundrel [369]

Answer:

The volume of the gas is $145.45\ cm^{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

$p*v=k$

we have

$v=16\ cm^{3}, p=20\ l/cm^{2}$

substitute and solve for k

$k=16*20=320$

The equation is $p*v=320$

<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>

For $p=2.2\ l/cm^{2}$ Find the value of v

substitute in the equation

$(2.2)*v=320$

$v=320/2.2=145.45\ cm^{3}$

Suppose the inside bottom of a box is painted with three colors: one-third of the bottom area is blue, one-sixth is red, and one

miss Akunina [59]

Answer:

The probability that the pebble will NOT land on color blue is 0.67.

Step-by-step explanation:

We attribute the box area as the probability of the events.

So the probability of landing in the Red Area is 1/6, the probability of landing in the Blue Area is 1/3 and the probability of landing in the Yellow Area is 1/2.

P(Red)= $\frac{1}{6}$

P(Yellow)= $\frac{1}{2}$

P(Blue)= $\frac{1}{3}$

The probability of landing in NOT Blue area is given by:

P(Not Blue)=1-P(Blue)= $1-\frac{1}{3}=\frac{2}{3} =0.67$
