Answer: 180 gallons needed

Step-by-step explanation:

Zykeith,

Assume x gallons of 50% antifreeze is needed

Final mixture is x + 60 gallons

Amount of antifreeze in mixture is 0.4*(x+60)

Amount of antifreeze added is .5x + .1*60 = .5x + 6

so .5x + 6 = .4(x + 60)

.5x -.4x = 24 -6

.1x = 18

x = 180

Let x be the number of gallons of the 50% antifreeze solution needed. We know that the resulting mixture will be 70 + x gallons. To get a 40% antifreeze mixture, we can set up the following equation:

\({\implies 0.5x + 0.1(70) = 0.4(70 + x)}\)

Simplifying the equation:

\(\qquad\implies 0.5x + 7 = 28 + 0.4x\)

\(\qquad\quad\implies 0.1x = 21\)

\(\qquad\qquad\implies \bold{x = 210}\)

\(\therefore\) We need 210 gallons of the 50% antifreeze solution to mix with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze.

The standard deviation of the sample is approximately 9.15

To find the standard deviation of the sample, we first need to calculate the sample mean. The sample mean is the sum of all the data points divided by the total number of data points. In this case, we are given the frequency distribution of the costs per load of 34 dish-washing detergents.

To calculate the sample mean, we multiply each class midpoint by its corresponding frequency, sum up these products, and divide by the total number of data points (34 in this case).

The class midpoint for each class interval can be calculated by adding the lower class limit to the upper class limit and dividing by 2. For example, the class midpoint for the interval 20-28 is (20 + 28) / 2 = 24.

Using this information, we can calculate the sample mean:

(24 * 13 + 33 * 15 + 42 * 4 + 51 * 2) / 34 = 32.44

Next, we need to calculate the squared deviation of each data point from the sample mean. The squared deviation is obtained by subtracting the sample mean from each data point and squaring the result.

For each class interval, we can calculate the squared deviation by subtracting the class midpoint from the sample mean, squaring the result, and multiplying by the frequency.

The sum of these squared deviations is then divided by the total number of data points minus 1 (n-1) to obtain the variance.

Using the given data, the variance is calculated as follows:

((24 - 32.44)^2 * 13 + (33 - 32.44)^2 * 15 + (42 - 32.44)^2 * 4 + (51 - 32.44)^2 * 2) / (34 - 1) = 83.6

Finally, to find the standard deviation, we take the square root of the variance:

√(83.6) ≈ 9.15

The income tax with the IRA is $6,582 and the income tax without the IRA is $5,774.

Without the IRA, his taxable income would be his gross income minus the standard deduction for a single taxpayer with no dependents, which is $12,550 in 2023:

Taxable income without IRA = $49,000 - $12,550 = $36,450

Using the tax table for single taxpayers, we can find that his income tax would be $5,773.75.

With the IRA, his taxable income would be his gross income minus the amount deposited into the IRA over the course of the year. Since he is depositing $589 each month, the total deposited in a year would be $589 * 12 = $7,068.

Taxable income with IRA = $49,000 - $7,068 = $41,932

On comparing the given expressions we get-

\(9^{-2} < (\frac{1}{9}) ^{-1}\)

\((\frac{1}{9}) ^{-1} < (\frac{1}{9}) ^{-2}\)

\(9^{-1} > 9^{-2}\)

Here, we are given 3 pairs of expression. Let us evaluate them one by one.

\(9^{-2}\) _ \((\frac{1}{9}) ^{-1}\)

The negative exponent means that the base is the reciprocal raised to a positive power. Thus, \(9^{-2}\) can be written as- \((\frac{1}{9}) ^{2}\) = 1/81

similarly, \((\frac{1}{9}) ^{-1}\) can be written as- \((9}) ^{1}\) = 9

Thus, the expression becomes-

1/81 _ 9

clearly we can see that 1/81 < 9

Now, we have \((\frac{1}{9}) ^{-1}\) _ \((\frac{1}{9}) ^{-2}\)

As shown above, the expression can be simplified as-

\((9) ^{1}\) _ \((9) ^{2}\)

9 _ 81

clearly we can see that 9 < 81

Next, we have- \(9^{-1}\) _ \(9^{-2}\)

we can write this as-

Step-by-step explanation:

The reflection of point (-6, -5) across the x-axis will give (-6, 5)

A reflection point occurs when a figure is constructed around a single point, known as the point of reflection or center of the figure.

Given is a point (-6, -5), we need to find the coordinates of the point when it is reflected across the x-axis,

The rule for a reflection across the x-axis -:

The rule for reflecting over the x-axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

i.e, (x, y) → (x, -y)

Therefore,

Candy spends £2.65, has 2/3 left and Candy has £7.95 money to start with.

Given that Candy spends £2.65 and has 2/3 of the initial amount left, we are required to find how much money Candy has to start with.

Solution:Let the initial amount of money Candy has be x.

Then, the amount of money spent by Candy = £2.65

Amount of money left with Candy = 2/3 of the initial amount

∴ Money left = 2/3 × x

Amount of money spent + money left = initial amount of money

Candy spends £2.65:2/3 of the initial amount left

= £ (x - 2.65)∴ 2/3 × x

= x - 2.65⇒ 2x/3

= x - 2.65⇒ 2x

= 3x - 7.95⇒ 3x - 2x

= 7.95⇒ x = 7.95

$7500 is the  amount invested in the 5% bonds

Let's call the principals (pre-profit amounts) of the 5% profit bonds F and the 12% profit bonds T.

The profit from the 5% bonds would thus be 0.05 * F, and the profit from the 12% bonds 0.12 * T

Then we have two equations, for two unknowns:

0.12 * T = 0.05 * F + 885  

T + F = 18000 (as the total amount invested into both those bonds is 18000)

Then T = (0.05 * F + 885) / 0.12 = 5/12 * F + 7375

Subtracting (T+F) from both sides, except on the other side (where the non-variable number is), we're going to subtract (T+F) by subtracting 18000. This will just give us a single equation in terms of one variable (F)

T - (T+F) = (5/12)*F + 7375 - 18000

-F = (5/12)*F - 10625

Let's solve for F by adding F to both sides of the last equation, getting us:

-F + F = 0 = 17/12 * F - 10625

This means 17/12 * F = 10625

F = 12/17 * 10625 = $7500

Hence the amount invested in the 5% bonds (before profit) is $7500
