You need to add 225mL of the 75% alcohol solution to obtain the desired 30% alcohol solution.

To find the amount of 75% alcohol solution needed to obtain a 30% alcohol solution, we must use the formula for dilution:

M1V1 = M2V2

Where M1 is the concentration of the initial solution, V1 is the volume of the initial solution, M2 is the desired concentration, and V2 is the desired volume.

In this case, M1 is 5%, V1 is 675mL, M2 is 30%, and V2 is unknown.

We can rearrange the equation to solve for V2, which is the volume of the 75% alcohol solution needed:

V2 = (M1V1) / M2

V2 = (5% x 675mL) / 30%

V2 = 225mL

From the given information provided, she has 14.50 dollars money left to spend on gift C.

To find out how much money is left for gift C, we first need to add up the amounts spent on gift A and gift B:

8 9/10 dollars + 6 3/5 dollars = (8 + 6) + (9/10 + 3/5) dollars

= 14 + (9/10 + 6/10) dollars

= 14 + 15/10 dollars

= 15 5/10 dollars

= 15.50 dollars

So the total amount spent on gift A and gift B is 15.50 dollars. To find out how much money is left for gift C, we need to subtract this amount from the total amount she has to spend:

Answer:

[tex]P = 56\sqrt2[/tex]

Step-by-step explanation:

We can find the perimeter of a square given its diagonal by modeling the square as two congruent right triangles and using the Pythagorean Theorem to solve for the square's side lengths.

The Pythagorean Theorem states that...

[tex]a^2+b^2=c^2[/tex], where [tex]a[/tex] and [tex]b[/tex] are the right triangles legs, and [tex]c[/tex] is its hypotenuse.

However, since we are working with a square, we know that the right triangles' legs are congruent. Thus, the theorem becomes:

[tex]a^2 + a^2 = c^2[/tex]

[tex]2 \cdot a^2 = c^2[/tex]

Using this formula, we can solve for the square's side lengths, inputting the given hypotenuse length of 28.

[tex]2 \cdot a^2 = 28^2[/tex]

↓ simplify the exponent

[tex]2 \cdot a^2 = 784[/tex]

↓ divide both sides by 2

[tex]a^2 = 392[/tex]

↓ take the square root of both sides

[tex]a = \sqrt{392}[/tex]

↓ simplify the square root

[tex]a = \sqrt{2^3 \cdot 7^2}[/tex]

[tex]a = (2\cdot 7)\sqrt{2}[/tex]

[tex]a=14\sqrt2[/tex]

Finally, we can multiply the side length by 4 to get the square's perimeter (since a square has 4 sides).

[tex]P = 4 \cdot a[/tex]

[tex]P = 4 \cdot 14\sqrt2[/tex]

[tex]\boxed{P = 56\sqrt2}[/tex]

[tex]\boxed{P \approx 79.2}[/tex]

so it shrunk by 19.3 - 18.1 = 1.2.

so if we take 19.3(origin amount) as the 100%, what's 1.2 off of it in percentage.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 19.3 & 100\\ 1.2& x \end{array} \implies \cfrac{19.3}{1.2}~~=~~\cfrac{100}{x} \\\\\\ 19.3x=120\implies x=\cfrac{120}{19.3}\implies x\approx 6.22[/tex]

The APR on the loan, given the amount you are to pay in interest every day, can be found to be 190. 54 %

To calculate the APR (Annual Percentage Rate) for this loan, we need to know the total interest paid over the course of a year, as a percentage of the loan amount.

First, we need to determine the total interest paid over the course of one year. Since the interest rate is $3.98 per day, we can multiply that by the number of days in a year (365) to get the total interest paid per year:

$3.98 x 365 = $1, 452.70

The APR would therefore be :

= ( 1, 452. 70 - 500 ) / 500

= 1. 9054

= 190. 54 %

For any real number x, x > 5 implies that x ≥ 5 is the true statement.

For any real number x, x > 5 implies that x ≥ 5 is the true statement. This can be expressed with the following inequality:

x > 5 implies x ≥ 5

This means that if x is greater than 5, then x must be greater than or equal to 5. We can demonstrate this with an example calculation. Let x = 6.

6 > 5

We can see that 6 is greater than 5, so the inequality is true.

6 ≥ 5

We can see that 6 is also greater than or equal to 5, so the inequality is also true. Therefore, for any real number x, x > 5 implies that x ≥ 5.

The probability of event Upper B 1 given event A is approximately 0.0134.

To find P(Upper B 1|A) using Bayes' rule, we need to use the formula:

P(Upper B 1|A) = P(A|Upper B 1) × P(Upper B 1) / P(A)

To find P(A), we can use the law of total probability:

P(A) = P(A|Upper B 1) × P(Upper B 1) + P(A|Upper B 2) × P(Upper B 2) + P(A|Upper B 3) × P(Upper B 3)

Substituting the given values, we get:

P(A) = 0.6 × 0.05 + 0.5 × 0.4 + 0.4 × 0.55

P(A) = 0.029 + 0.2 + 0.22

P(A) = 0.449

Now, substituting the values of P(A|Upper B 1), P(Upper B 1), and P(A) into the Bayes' rule formula, we get:

P(Upper B 1|A) = (0.6 × 0.05) / 0.449

P(Upper B 1|A) = 0.006 / 0.449

P(Upper B 1|A) ≈ 0.0134

Step-by-step explanation:

The picture in this question can be a little deceiving. Each rectangular glass pane is 3 by 10 inches. This means that the picture of the 4 panes overlapping, leaves the center square open. The open area has your inner edges. The question asks for the sum of the inner and outer edges.

Every pane is 10 inches long, so the out perimeter of the figure is 40 inches because the figure has four sides. The rectangles overlap, creating 3 by 3 inch square. 3 inches off either side of a pane leaves 4 inches as the length for the edge of the inner square. Therefore, the perimeter of the inner square is 16 inches.

Outer Perimeter + Inner Perimeter = 40 + 16 = 56 inches

The probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.

To find the percentage of students scoring 84 or more, first we need to calculate the z-score using the formula:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Using a standard normal table or a calculator, we can find the percentage of students scoring 84 or more as:percentage = 1 - P(Z < 0.7895)percentage ≈ 21.4%Therefore, approximately 21.4% of students will score 84 or more on the test.b) To find the probability of a random student scoring 84 or more if the maximum score is 95, we need to first calculate the z-score using the same formula as before:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Then, we need to convert this z-score to a new z-score based on the maximum score of 95. Using the formula:z = (X - μ) / (max score - μ)σwhere X = 84, μ = 72, σ = 15.2, and max score = 95z = (84 - 72) / (95 - 72)z ≈ 1.19Using a standard normal table or a calculator, we can find the probability of a student scoring 84 or more as:P(Z > 1.19)P(Z > 1.19) ≈ 0.1179Therefore, the probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.

Answer:

Part A:

To find the total length of sides 1 and 2 of the triangle, we need to add the lengths of these sides:

Side 1 + Side 2 = (3x^2 - 4x - 1) + (-x^2 + 4x + 5)

Simplifying the expression by combining like terms, we get:

Side 1 + Side 2 = 2x^2 + 1

Therefore, the total length of sides 1 and 2 of the triangle is 2x^2 + 1.

Part B:

To find the length of the 3rd side of the triangle, we can subtract the sum of sides 1 and 2 from the perimeter of the triangle:

5x^3 - 2x^2 + 3x - 8 - [(3x^2 - 4x - 1) + (-x^2 + 4x + 5)]

Simplifying the expression by distributing the negative sign, and then combining like terms, we get:

5x^3 - 2x^2 + 3x - 8 - 2x^2 + 8x + 4

Simplifying further by combining like terms, we get:

5x^3 - 4x^2 + 11x - 4

Therefore, the length of the 3rd side of the triangle is 5x^3 - 4x^2 + 11x - 4.

(√122 - √10)/112.

Step-by-step explanation:

The average rate of change of a function f(x) over an interval [a, b] is given by:

average rate of change = (f(b) - f(a))/(b - a)

Here, we have f(x) = √x - 1, a = 10, and b = 122. So, the average rate of change of f(x) from x = 10 to x = 122 is:

(f(122) - f(10))/(122 - 10)

= (√122 - 1 - √10 + 1)/(112)

= (√122 - √10)/112

Therefore, the exact, fully simplified answer for the average rate of change of f(x) from x = 10 to x = 122 is (√122 - √10)/112.

45% of the burgers served were well-done.

What is percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

To find the percentage of well-done burgers, we need to divide the number of well-done burgers by the total number of burgers served and then multiply by 100 to get the percentage.

Total number of burgers served = 9 well-done + 11 medium = 20

Percentage of well-done burgers = (9/20) x 100% = 45%

Therefore, 45% of the burgers served were well-done.
