Pamelas age is. 2 times jiris age. The sum of their ages is 30.what is jiris age?

Anettt [7]

Answer: 10

p = Pamela’s age, j = Jiris’ age

2j = p
p + j = 30

Then change things around a bit...
p + j = 30 or
30 - p = j

Then substitute
2(30 - p) = p

And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20

A twelve-sided die with sides labeled through will be rolled once. Each number is equally likely to be rolled. What is the proba

FromTheMoon [43]

<em>Complete Question:</em>

<em>A twelve-sided die with sides labeled 1 through 12 will be rolled once. Each number is equally likely to be rolled, what is the probability of rolling a number greater than 10?</em>

Answer:

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

Step-by-step explanation:

Given

Number of Sides = 12

Required

Probability of obtaining a side greater than 10

We start by listing out the sample space;

$S = \{1,2,3,4,5,6,7,8,9,10,11,12\}$

$n(S) = 12$

Next, we list out digits greater than 10; Represent this with T

$T = \{11,12\}$

$n(T) = 2$

Probability of T is calculated as follows;

$P(T) = \frac{n(T)}{n(S)}$

$P(T) = \frac{2}{12}$

Divide the numerator and denominator by 2

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

<em>Hence, the required probability is </em> $\frac{1}{6}$ <em />

Noah has 5 pieces of bubble gum to share with his 5 teammates. He wants to give each teammate the same number of pieces. How man

Talja [164]

Answer:

1 each

Step-by-step explanation:

Given that Noah has 5 pieces of bubble gum

There are 5 teammates of Noah.Noah wants to share the 5 pieces among 5.

Since there are exactly 5 pieces and there are 5 team mates, the no of piece that can be given to each team mate =1

So if 1 piece is given to teammate, there will be equal distribution of bubble gum pieces to all 5 team mates.

Verify:

If 1 is given to each of 5 teammates, the number of bubble gum pieces required =5

This is equal to the no of pieces Noah has.
