The number of guests at the wedding is 276.

Since 1/3 of the guests choose beef and 5/12 choose chicken, the fraction for vegetarian will be:

= 1 - (1/3 + 5/12)

= 1 - 3/4

= 1/4

Therefore, let the total number of guests be x.

This will be illustrated as:

1/4 × x = 69

0.25x = 69

Divide

x = 69 / 0.25

x = 276

Therefore, there are 276 guests.

According to the given depression angle, ship is 4.4 miles apart from ship B.

Depression angle:

Depression angle refer an angle that is formed with the horizontal line if the line of sight is downward from the horizontal line.

Given,

A pilot is flying over the ocean. She determines that the angles of depression to two ships are 74° and 48°, as shown in the figure below. The plane is 5 miles from the ship located at point A.

Here we need to find the distance between the two ships.

Here we know the following,

Distance between plane and Ship A = 5 miles.

And the depression angle = 74°, 48°

Let us consider the following, that they sit on a line,

So under this situations,

=> 80 - 48 - 74 = 58 degrees.

The next thing we have to do is bring this 74 degree angle inside the diagram. Because it is congruent to this interior angle because they are alternate.

Then it can be written as,

=> x = sin 74°/5

=> x = 4.4

Therefore, the two ships are 4.4 miles apart from each other.

Monthly Payment Formula

[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]

where:

Given:

Substitute the values into the formula to calculate the monthly payment:

[tex]\implies \sf PMT=\dfrac{12000(0.00415)\left(1+0.00415\right)^{60}}{\left(1+0.00415\right)^{60}-1}[/tex]

[tex]\implies \sf PMT=\dfrac{49.8\left(1.00415\right)^{60}}{\left(1.00415\right)^{60}-1}[/tex]

[tex]\implies \sf PMT=\dfrac{63.84764727}{0.2820812705}[/tex]

[tex]\implies \sf PMT=226.3448656[/tex]

Therefore, the total payments over the life of the loan is the monthly payment multiplied by the total number of months:

[tex]\implies \sf 226.3448656 \times 60=\$13580.69[/tex]

To calculate how much interest Jessie pays over the life of the loan, subtract the original loan amount from the total payments amount:

[tex]\implies 13580.69-12000=\$1580.69[/tex]

Therefore, the interest Jessie will pay over the life of the loan is $1580.69.

The amounts drained by each pipe, considering a system of equations, are given as follows:

The variables to the system of equations are presented as follows:

A water tank holds a total of 5,600 gallons, hence:

x + y + z = 5600.

Pipe B drains twice as much as pipe A, hence:

y = 2x.

Pipe C drains 65 gallons more than pipe B, hence:

z = 65 + y = 65 + 2x.

Replacing the last two equations into the first, the amount drained by Pipe A is obtained as follows:

x + y + z = 5600.

x + 2x + 65 + 2x = 5600

5x = 5535

x = 5535/5

x = 1107 gallons.

The simplest radical form of the radicals given are:

1. The simplest radical form of √175 is 5 √7.

2. The simplest radical form of √5 / 12 is √5 / 12.

First, let us understand the radical:

A radical can also be called a surd. A surd is an irrational number. We say that it is irrational because it can not be expressed as a terminating decimal.

1.

We are given:

√175

We need to write in the simplest radical form.

175 can be written as:

175 = 5 * 5 * 7

√175 = √ 5 * 5 * 7

√175 = √ 5 * 5 * √7

√175 = 5 √7

So, the simplest form of √175 is 5 √7.

2.

We are given:

√5 / 12

We need to write in the simplest radical form.

√5 / 12 is already in the simplest form.

So, the simplest form of √5 / 12 is √5 / 12.

Thus, the simplest radical form of the radicals given are:

1. The simplest radical form of √175 is 5 √7.

2. The simplest radical form of √5 / 12 is √5 / 12.

From the table we can see that the line passes through the points:

(-6,6) ,(5,-3) ,(4,0) and (3,3) .

Let us consider any two points on the line (4,0) and (3,3) .

We know that the slope of the line can be found by using the intercept formula

Hence slope = (3-0) / (3-4) = 3/ -1 = -3

Now the equation of the line is :

y - 3 = -3(x-3)

or, y - 3 = -3x +9

or, y + 3x = 6

The letter m is frequently used to represent the slope of an object that resembles a line in the plane that contains the x and y axes. The slope is defined as the difference in two independent locations along the line expressed in y coordinate less by the equivalent difference in x coordinate.

Each individual paid the sum of $23.4 including state tax at the restaurant

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%".

In the problem, their total bill is $50.88 and they gave a 30% tip

We should fid 30% of 50.88

0.3 * 50.88 = $15.264

30% of $50.88 is $15.264

If we add this up and then find the state tax to it.

15.264 + 50.88 = 66.144.

Find 6% of 66.144 to determine the state tax.

0.06 * 66.144 = 3.96864

The total amount spent is 66.144 + 3.96864 = 70.11264

We can divide this equally amongst the three people to get the individual payment = 70.11264/3 = 23.37088

Rounding this to the nearest cent, we have 23.4.
