Final answer:

The business woman invested $17,000 in the 3.5% interest account and $21,000 in the 6.5% interest account.

Explanation:

To find how much she invested in each account:

Let x be the amount invested at 3.5% interest and y be the amount at 6.5%.

We can set up a system of equations like this: x + y = $38,000 and 0.035x + 0.065y = $1,960.

Solving this system, we get x = $17,000 and y = $21,000.

Therefore, investment is $17,000 in the 3.5% interest account, $21,000 in the 6.5% interest account

Final answer:

A person earning $500,000 per year received an additional $16,386 or 3.3% more of their income due to tax changes.

Explanation:

To ascertain how much more a person earning $500,000 per year received due to tax changes, we need to calculate the savings from the first $106,800 at a 2% reduction, in addition to the increased federal tax return of $14,250.

Firstly, we calculate 2% of $106,800:

0.02 × $106,800 = $2,136

Now, we add this to the additional amount received from the tax return:

$2,136 + $14,250 = $16,386

Therefore, a person earning $500,000 per year has received an additional $16,386. To find the percentage this additional amount represents of their income, we perform the following calculation:

($16,386 / $500,000) × 100 = 3.277%

Rounded to the nearest tenth of a percent, it is 3.3%.

The statement completed would be: A person earning $500,000 a year received $16,386 more or 3.3% more of their income.

Answer:

n = 2

Step-by-step explanation:

As per statement of the question we will form the equation first.

[tex](\frac{3}{5})n-\frac{4}{5}=(\frac{1}{5})n[/tex]

Now we will solve the given equation to get the solution of n.

[tex](\frac{3}{5})n=\frac{4}{5}+(\frac{1}{5})n[/tex]

[tex](\frac{3}{5})n-(\frac{1}{5})n=\frac{4}{5}[/tex]

[tex](\frac{3-1}{5})n=\frac{4}{5}[/tex]

[tex](\frac{2}{5})n= \frac{4}{5}[/tex]

Now we cross multiply the fractions

(2×5)×n = 4×5

10.n = 20

[tex]n=\frac{10}{5}=2[/tex]

Therefore answer is n = 2

Final answer:

To find the future price of milk after a 54% increase, multiply the current price by 1.54. For 2 gallons of milk costing $2.50 now, the future price will be $3.85.

Explanation:

To calculate the future price of milk after a 54% increase over 3 years, we first need to determine the percentage increase in decimal form and then apply it to the current price. An increase of 54% is equivalent to a multiplier of 1.54 in decimal form.

Therefore, if 2 gallons of milk currently cost $2.50, we calculate the future cost by multiplying $2.50 by 1.54.

Here's the calculation:

Convert the percentage increase to a decimal: 54% = 0.54.

Add 1 to the decimal to account for the total value after the increase: 1 + 0.54 = 1.54.

Multiply the current price of 2 gallons of milk by the increase factor: $2.50 x 1.54 = $3.85.

After a 54% increase, the price for 2 gallons of milk will be $3.85.

To find the distance between Tim and Terry after 18 minutes, you can calculate the distance each has traveled based on their speed and time elapsed. Then subtract their distances to find the total distance between them.

To determine the distance between Tim and Terry after 18 minutes, you can add up the distances each has traveled according to their speeds and time elapsed. Tim covers 90 feet/minute, so in 18 minutes, he would have traveled 90 * 18 = 1620 feet. Terry covers 11 feet/minute, so in 18 minutes, he would have traveled 11 * 18 = 198 feet.

Calculating the total distance between them:

Distance = |1620 - 198| = 1422 feet

In order to find the reciprocal of a number, we should just flop it over.

If we're asked to find the reciprocal of a fraction, then the numerator & denominator of the fraction switch places.

If we're asked to find the reciprocal of an expression, then we also flop it over, like so:-

[tex]\pmb{u^2-s^2}\longmapsto\pmb{\displaystyle\frac{u^2-s^2}{1} }\longmapsto\pmb{\displaystyle\frac{1}{u^2-s^2} }[/tex]

Explanation of steps:-

First, I turned the expression into a fraction by adding a denominator of 1.

Then, I flopped it over and found the reciprocal.

Hence, the reciprocal of u²-s² is:-

[tex]\bigstar{\boxed{\pmb{\displaystyle\frac{1}{u^2s^2} }}}[/tex]

Final answer:

You can make 19 cheese sandwiches with 38 bread slices and 28 cheese slices.

Explanation:

In this scenario, you have 38 bread slices and 28 cheese slices. The equation for a cheese sandwich is 1 sandwich = 2 slices of bread + 1 slice of cheese. So, if you set the number of bread slices to '2' and the number of cheese slices to '1', you can calculate how many cheese sandwiches you can make.

First, divide the number of bread slices (38) by 2 to get the number of sandwiches that can be made with the bread: 38 / 2 = 19 sandwiches.

Next, divide the number of cheese slices (28) by 1 to get the number of sandwiches that can be made with the cheese: 28 / 1 = 28 sandwiches.

Since you can only make 19 sandwiches with the available bread, the limiting factor is the bread. Therefore, you can make 19 cheese sandwiches with the given amounts of bread and cheese.

The equation [tex]d=(m)/(V)[/tex] can be used to calculate the density, [tex]d[/tex], of an object with mass, [tex]m[/tex], and volume, [tex]V[/tex].  [tex](m)/(d)=V[/tex] is an equivalent equation solved for [tex]V[/tex].

To find the equation equivalent to [tex]d= m/V[/tex] solved for [tex]V[/tex], we need to isolate [tex]V[/tex]on one side of the equation.

Given the equation [tex]d= m/V,[/tex] where [tex]d[/tex] represents density, [tex]m[/tex] represents mass, and [tex]V[/tex] represents volume.

To solve for [tex]V[/tex] , we can rearrange the equation:

[tex]d= m/V[/tex]

First, let's get rid of the fraction by multiplying both sides by [tex]V[/tex]:

[tex]d*V=m[/tex]

Now, to isolate [tex]V[/tex], we need to divide both sides by [tex]d[/tex]:

[tex]V= m/d[/tex]

So, the equivalent equation solved for [tex]V[/tex] is:

[tex]V= m/d[/tex]
