A game involves rolling a fair six-sided die. If the number facing upward on the die is a whole number multiple of three, the pl
BaLLatris [955]
There is only two multiples of three on a six-sided die, the 3 side, and the 6 side.

3 x 20 = 60
6 x 20 = 120
120 + 60 = 180

$180.00 is your possible winnings total, but the question asks for your expected value on EACH roll, so you divide 180 by 6(sides on a die) to get your final answer

180/6 = 30

ANSWER: D. $30.00

What is 5/14+1/6 I really need help
-Dominant- [34]
First thing to do, when you have to add 2 fractions, you have to make both denominators equal. 14/6 = 0.84, so can't multiply or divide any fraction by a whole number to get the other denominator.
So, you multiply each fraction by the denominator of the other fraction. Which means that you multiply 5/14 by the denominator of 1/6 which is 6, and you multiply 1/6 by the denominator of 5/14 which is 14.
5/14 + 1/6 = 30/84 + 14/84
Then you join both fractions to make them under one denominator, since both denominators are equal.
30/84 + 14/84 = (30+14)/84 = 44/84.
Now, you need to simplify the fraction: you divide both numerator and denominator by 4:
44/84 = 11/21

So 5/14 + 1/6 = 11/21

Hope this Helps! :)

<u>Answer</u>

√7 × √5

√3 × √2


<u>Explanation</u>

√9*√16   = 3 × 4

              = 12

             = 12/1      ⇒ It is a rational answer.

√7*√5  = √(7×5)

            = √35

           = 5.916079783.... ⇒ Irrational

√3*√2  = √(3×2)

           = √6

            = 2.449489743...  ⇒  Irrational

4√2*√2 = 4 × √(2×2)

              = 4 × √4

              = 4 × 2

              = 8

              = 8/1   ⇒  It is rational

The expressions that would give irrational answers are: √7*√5  and√3*√2

Calcule o saldo de salário, o funcionário foi admitido em 10 de janeiro como mensalista, salário R$ 1400,00?
Sholpan [36]

Responda:

$ 980

Explicação passo a passo:

Dado que:

Salário mensal = $ 1400

Data de emprego = 10 de janeiro

Usando o sistema de mês de 30 dias:

Taxa diária =. $ 1400/30 = $ 46.66666

Dias não trabalhados = janeiro - 9 de janeiro = 9 dias

Subtraia o salário de 9 dias do total:

Salário total - (9 * taxa diária)

$ 1400 - (9 * $ 46,66666)

$ 1400 - $ 420

= $ 980

Portanto, o saldo do salário é de $ 980
