If the zoo had 6 dolphins how many penguins would there be?
Answers
The number of penguins is 15.
What is a ratio?
The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of dolphins to penguins = 2:5
This means,
For every 2 dolphins, there are 5 penguins.
Now,
For 6 dolphins,
2 dolphins = 5 penguins
Multiply 3 on both sides.
6 dolphins = 15 penguins
Thus,
There will be 15 penguins.

A major concern with Social Security is the possibility that funds will not be available when today’s tax-payers retire to become beneficiaries. According to the Social Security Trustee’s report, an increase of 1.89% in the Social Security payroll tax would keep the account full for the next 75 years. To achieve similar results, benefits would have to be decreased from the current 42% of the ending salary to 29% of the salary.Cindy is relatively new to the workforce.

Answer: Hello mate!
Ok, the 6 sides cubes can be thinked as two normal dice.
A fair game is that game where both players have the same chance to win, first, let's calculate the situations where you friend win:
this are, if the cubes have numers between 1 and 6:
1 + 6
6 + 1
2 + 5
5 + 2
3 + 4
4 + 3
where 1 + 6 is different to 6 + 1 because in the first one you rolled a 1 and your friend a 6, and in the second one you rolled a 6 and your friend a 1, so are different events.
Then you can see that you friend has 6 combinations where he wins.
So we need to find two numbers that between them, have the same number of combinations.
I can think, for example in 4 and 10:
the combinations for 4 are:
2 + 2
3 + 1
1 + 3
a total of 3 combinations:
for 10 are:
5 + 5
4 + 6
6+ 4
also 3 combinations.
So if you win a point if the sum is 4 or 10, you also have 6 combinations where you win, then the game is fair
Now, suppose the first number is 5, let's find the second:
the combinatios for 5 are:
4 + 1
1+ 4
2 + 3
3 + 2
a total of 4 combinations, this means that we need to find another number that only has two combinations, wich can be, for example, 3
the combinations for 3 are:
1 + 2
2 + 1
2 combinations, then if your numbers are 3 and 5, you have 6 combinations where you win, and the game is fair.
There are 6 ways to get a sum of 7 using a pair of dice:
1+6
6+1 You might be asking why 2+5 isn't the same as 5+2
2+5 Imagine the dice are different colors. Is a red 2 and green 5 the
5+2 same as a green 2 and red 5? (No, it's not)
3+4
4+3
You need two numbers that also provide 6 ways to win. One pair that would work is 11 and 9 There are two ways to make 11 (5+6) and (6+5) and there are four ways to make 9 (3+6), (6+3) (4+5) and (5+4) - that's a total of six ways. So to balance your friend's 7 - you could go for sums of 11's and 9's. Check the choices you were given and find the numbers (it could be three numbers like 2,3, and 12) that give you 6 ways to win.
Here are the numbers and their ways

y < 5x + 2
y >=1/2(x) + 1

Plug in the ordered pair (x,y) in each inequality
2 < 5(-3) + 2 -----> false
(–1, 3)
3< 5(-1) + 2 --------> false
(0, 2)
2 < 5(0) + 2 -------> false
(1, 2)
2 < 5(1) + 2 ---------> True
2 >=(1/2)1 + 1 ----------->True
