To solve this problem we can use the rule of 3 and solve for x. Let's equate it as the following:

28.52/x=36.8/100

Why did I represent it like that?
In the first numerator we have the known quantity (28.52). In the second numerator we'll need the percentage that 28.52 represents (because the second fraction will represent percents). This will be 36.8%
The first denominator is x (the number we want to figure out). That number represents 100%. Hence the 100 as the second denominator.

To solve for x we need to do the following:
x=(28.52*100)/ 36.8
x=2852/36.8
x=77.5

Answer: 28.52 is 36.8% of 77.5

The correct answer is: 36.8% of 77.5 is 28.52

Explanation:

Simply translate "36.8% of what number is 28.52" mathematically as follows:

36.8% * x = 28.52 --- (1)

x represents "what number" in the sentence

= represents "is."

Now, we can write 36.8% as \frac{36.8}{100} when we remove the % symbol. Rewrite equation (1) as follows:

\frac{36.8}{100} * x = 28.52

Now evaluate for x:

\frac{36.8}{100} * x = 28.52 \\ x = \frac{100}{36.8}*28.52 =  77.5 \\

Hence the correct answer is 36.8% of 77.5 is 28.52.

What is the hydronium ion (H3O+) concentration in milk if it has a pH of 8.2?
valkas [14]
The hydronium ion is H₃O⁺ and its concentration is equivalent to the H⁺ ion concentration. The H⁺ ion concentration is given by:

pH = -log[H⁺]
[H⁺] = 10^(-8.2)
[H⁺] = 6.31 x 10⁻⁹ mole/dm³

The hydronium ion concentration is 6.31 x 10⁻⁹ mole/dm³

A service station checks Mr. Gittleboro's radiator and finds it contains only 30% antifreeze. If the radiator holds 10 quarts an
Andrew [12]

Answer:

2.86 quarts ( approx )

Step-by-step explanation:

Given,

The initial quantity of the Mr. Gittleboro's radiator that contains 30% antifreeze = 10 quarts,

Let x quarts of pure antifreeze replaced x quarts of Mr. Gittleboro's radiator to bring it up to a required 50% antifreeze,

So, the quantity of 30% antifreeze radiator after drained off x quarts = (10-x) quarts

Also, the quantity of final antifreeze radiator 50% antifreeze = 10 quarts

Thus, we can write,

30% of (10-x) + 100% of x = 50% of 10

30(10-x) + 100x = 500

300 - 30x + 100x = 500

300 + 70x = 500

70x = 200

x = 2.85714285714 quarts ≈ 2.86 quarts
