Answer:

52.8%

Step-by-step explanation:

The amount of alcohol is:

0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints

So the concentration is:

5.28 pints / 10 pints × 100% = 52.8%.

Novosadov [1.4K]

Answer:

  210

Step-by-step explanation:

We can write the ratio as ...

  bagels : scones = 2 : 3

Then bagels are 2/(2+3) = 2/5 of the total.

  # bagels = (2/5)(525)

  # bagels = 210

2 1/4 ⋅ 1 2/3<br> as a mixed number
Gemiola [76]

Answer:

3\frac{3}{4}

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

\frac{9*5}{4*3}

\frac{45}{12}

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

3\frac{3}{4}

30 pts! solve the following equation. (x - 18)^2 = 1
melamori03 [73]

Answer:

D - x = 19 x = -17

Step-by-step explanation:

Factor the equation to make the problem easier - you should have this:

(x - 18) (x + 18) = 1

Set each binomial to 1:

x - 18 = 1

x + 18 = 1

This should give you x = 19 and x = -17
