56/28 = 122/x
56x = 122(28)
56x = 3416
56x/56 = 3416/56
x = 61

Answer:

56 : 28 as 122 : 61

Step-by-step explanation:

Proportion says that two ratios or fractions are equal.

As per the statement:

56 : 28 :: 122 : ?

Let x be the fourth proportion.

then;

56 : 28 :: 122 : x

by definition of proportion:

\frac{56}{28}=\frac{122}{x}

by cross multiply we have;

56x = 3,416

Divide both sides by 56 we have;

x = 61

Therefore, 56 : 28 as 122 : 61

There are 1493 men and 1438 women in the audience at a concert. What is the percentage of the audience that are men
Advocard [28]
To calculate this answer you have to sum up the amount of women and amount of men at the concert: 1493 + 1438 = 2931.

Now you have the total amount of people. To get the precentage of the audience that are men, you do this: 1493/2931. (you divide the amount of men with the amount of every person present). 

1493/2931 = 0.5093

you multiply 0.5093 by 100

and you get 50.93%. And that is the final answer.

What is the smallest integer greater than the square root of 68?
Talja [164]
This question is essentially just determining whether you understand the definition of integers and square roots. The square root of a quantity is a number that when multiplied with itself gives that quantity. The square root of 68 is expressed as:

√68 = 8.25

The square root of 68 is roughly 8.25. Now, an integer is simply a whole number, which is a number that is not a fraction. Therefore, the smallest integer that is greater than 8.25 is simply the next whole number, which is 9.

The smallest integer greater than the square root of 68 is 9.

Solve the simultaneous equation
Sunny_sXe [5.5K]
Here are the original equations:
2x + 2y = 14
x + 2y = 11
We immediately note that these two equations form a system. So, we can use substitution to solve the second equation for x. To do this, all that needs to be done is to subtract 2y from both sides, to get x = 11 - 2y. Next, we substitute the derived expression for x into the first equation to get 2(11-2y) + 2y = 14. We can use the distribute property to get 22 - 4y + 2y = 14. Then, we can combine like terms to get 22 - 2y = 14. After that, we subtract 22 from both sides to get -2y = -8. Finally, we divide -2 from both sides to get y = 4. 

Now that we have the value for y, we can substitute our derived value into the second equation, since it will be much faster. After doing this, we get x + 2(4) = 11. We can simplify the left side of the equation and subtract the product from both sides, which gives us x = 4. Therefore, the answer to your query is x = 4, y = 4. Hope this helps and happy Halloween!
