Answer:

Rational

Step-by-step explanation:

Irrational numbers are numbers that cannot be written as a fraction (denominator of 1 does not count). 2.99 can easily be written as a fraction (e.g.  \frac{299}{100}) and therefore is rational.

pashok25 [27]
On the added picture is given a table of all possible die rolls, for example, under a pair (2,3) you mean that Bo rolls 2 on a die and Amaya rolls 3.

All red shaded cells responds to those choices, when Amaya rolls more than Bo.

Let's count: all possible rolls make up 36 choices and red shaded rolls make up 15 choices, then the probabiliry is

\dfrac{15}{36} = \dfrac{5}{12}.

Answer: \dfrac{5}{12}.

Troyanec [42]

Answer:

The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.

Step-by-step explanation:

Given;

distance measured by odometer in kilometer, = 810 km

distance measured by odometer in miles, = 510 miles

The  ratio of a unit rate of kilometers to miles of the distance measured by the odometer is calculated as;

d = \frac{810 \ km}{510 \ miles} \\\\d = \frac{810 \ km \ \times \ \frac{1}{810 \ km} }{510 \ miles \ \times \frac{1}{810 \ km} } \\\\d = \frac{1 \ km}{\frac{510}{810} \ miles } \\\\d = \frac{1 \ km}{\frac{17}{27} \ miles} \\\\d = 1 \ km : \frac{17}{27} \ miles\\\\d = 1 \ km : 0.63 \ miles

Therefore, the ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.
