Ken, Mike, and Ariel are eating out at their favorite restaurant. They each order a sandwich combo and plan to split the bill evenly. The service they receive at the restaurant is amazing, so they decide to leave a 30% tip. Their bill total is $50.88 before tax. If Florida’s sales tax is 6%, how much will each person pay? Round your answer to the nearest hundredth.
Each individual paid the sum of $23.4 including state tax at the restaurant
PercentageIn 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.
We can say each person paid $23.4 at the end of the day

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. How far apart are the ships? Round your answer to the nearest tenth of a mile.
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.

The amount of money in the account after 10 years will be $42113.64.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
As per the given,
Principle amount P = $18000
Rate of interest r = 8.5% = 0.085
Time t = 10
By continuous compounding interest formula,
P = (18000)[tex]e^{0.085\times10}[/tex]
P = $42113.64
Hence "The amount of money in the account after 10 years will be $42113.64".

The amounts drained by each pipe, considering a system of equations, are given as follows:
Pipe A: 1107 gallons.Pipe B: 2214 gallons.Pipe C: 2279 gallons.What is the system of equations?The variables to the system of equations are presented as follows:
Variable x: amount of water drained by Pipe A.Variable y: amount of water drained by Pipe B.Variable z: amount of water drained by Pipe C.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.
Hence the remaining amounts are given as follows:

Step-by-step explanation:
Monthly Payment Formula
[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]
where:
PMT = Monthly payment.P = Loan amount.i = Interest rate per month (in decimal form).n = Term of the loan (in months).Given:
P = $12,000i = 0.0498/12 = 0.00415n = 5 years = 60 monthsSubstitute 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 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.

find the slope of the line passing through the points (-2,2) and (-5,5)
Answer:
The slope of the line passing through the points [tex](-2, 2)[/tex] and [tex](-5, 5)[/tex] is equal to: [tex]-1[/tex]
Step-by-step explanation:
The slope of a line can be found with the following formula
[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where [tex]x_2 > x_1[/tex]
Then substituting the values with the given ones we have
[tex]m=\frac{y_2 - y_1}{x_2 - x_1} = \frac{2-5}{-2-(-5)}=\frac{-3}{-2+5}=\frac{-3}{3} =-1[/tex]
So the slope of the line passing through the given points is [tex]-1[/tex]
