If I mix 5 gallons of p% boric acid with 5 gallons of water, what is the concentration of the mixture?

Trava [24]

Answer: The concentration of the mixture is 0.5 p % .

Step-by-step explanation:

Given: 5 gallons of p% boric acid is mixed with 5 gallons of water.

Amount of boric acid = p% of 5 gallons

$=\dfrac{p}{100}\times5\text{ gallons}= 0.05p\text{ gallons}$

Total solution : 5 +5 = 10 gallons

then, the concentration of the mixture = $\dfrac{\text{Amount of boric acid in solution}}{\text{Total solution}}\times100$

$=\dfrac{0.05p}{10}\times100\\\\=0.5p$

Hence, the concentration of the mixture is 0.5 p % .

Evaluate and match each expression on the left to its value on the right, when x=8 and y=3.

Crank

Answer:

12-y------------> 9

3x-y------------>21

4y-10----------->2

1/4 xy-----------> 6

Solution,

Given,

X=8

y=3

Now,

$1. \: \: 12 - y \\ \: \: \: = 12 - 3 \\ \: \: = 9 \\ 2. \: \: 3x - y \\ \: \: = 3 \times 8 - 3 \\ \: \: = 21 \\ 3. \: \: 4y - 10 \\ \: \: = 4 \times 3 - 10 \\ \: = 12 - 10 \\ \: \: = 2 \\ 4. \: \: \frac{1}{4} xy \\ \: \: = \frac{1}{4} \times 8 \times 3 \\ = 6$

hope this helps...

How do you figure out if one fraction is more/larger than another fraction?

SOVA2 [1]

There are several ways,
One, which is easiest, is to divide them, if the result is greater than 1, then the fraction at the numerator is larger. If the answer is less than 1, then the fraction at the denominator is larger.
Another way, is to try making both fractions have the same denominator and compare; the one with greater numerator is the larger fraction.

Hope this helps!
