Answer:
c. $19,813.56
Explanation:
Given:
• Lisa receives a net pay of $619.06 biweekly.
,• $143 is withheld from her pay each pay period.
We are required to find her annual gross salary.
First, determine her gross salary for each pay period.
[tex]\begin{gathered} \text{Gross Salary}=\text{Net Pay+Deduction} \\ =619.06+143 \\ =\$762.06 \end{gathered}[/tex]Next, determine the number of payment periods.
[tex]\begin{gathered} \text{Lisa is paid biwe}ekly,\text{ that is every 2 weeks.} \\ The\text{ number of weeks in a year}=52 \\ \text{Therefore:} \\ \text{The number of payment periods}=\frac{52}{2}=26 \end{gathered}[/tex]Finally, multiply her gross salary per period by the number of periods to get her annual gross salary.
[tex]\begin{gathered} \text{Gross annual salary}=26\times762.06 \\ =\$$19,813.56$ \end{gathered}[/tex]Lisa's annual gross salary is $19,813.56.

The first step is to use the PEMDAS, and this rule ensures that certain rules are followed in number operations. It simply means some mathematical signs would be given preference over the others. The acronym PEMDAS ensures that Exponents comes first, followed by Multiplication, Addition an then Subtraction. In this question, the Multiplication sign would be considered first and so we now have;
7 + [6 x 5] - 2
7 + 30 - 2
Then the addition sign would take prefernce now, and you have

A starship is orbiting lax, a large moon of the planet sylow II. The ships sensor array detects that the temperature on the surface of the moon is -12.3 f. What is the temperature in degrees Celsius
Answers
The temperature in degrees celsius of the surface of the moon is -24.6111.
Fahrenheit and Celsius are directly proportionate to one another due to their relationship. When the temperature rises on the Celsius scale, it likewise rises on the Fahrenheit scale. Similar to how the Celsius scale, the Fahrenheit scale similarly drops in temperature when the Celsius scale does.
The ships sensor array detects that the temperature on the surface of the on is -12.3 F.
To convert the Fahrenheit to Celsius we will use the given formula.
[tex]C=\frac{5}{9}(F-32)[/tex]
Given F=-12.3
Substituting F in the equation, we get
[tex]C=\frac{5}{9}(-12.3-32)[/tex]
[tex]C=\frac{5}{9}(-44.3)[/tex]
[tex]C=\frac{-221.5}{9}[/tex]

How many triangles exist that fit the following criteria?B = 30°, a = 4, b = 3
Answers
Given:
B = 30°, a = 4, b = 3
We will solve the triangle to find how many triangles exist that fit the given data
We will use the sine rule to find the angle A as follows:
[tex]\begin{gathered} \frac{a}{sin(A)}=\frac{b}{sin(B)} \\ \\ \frac{4}{sin(A)}=\frac{3}{sin(30)} \\ \\ sin(A)=\frac{4}{3}sin(30)=\frac{2}{3} \\ \end{gathered}[/tex]So, the measure of angle A will be as follows:
[tex]A=sin^{-1}(\frac{2}{3})=41.81\degree,or,138.19\degree[/tex]Now, we will find the measure of angle C using the fact that the sum of the angles = 180
[tex]\begin{gathered} C=180-(A+B) \\ A=41.81\degree\rightarrow C=180-(30+41.81)=108.19\operatorname{\degree} \\ A=138.19\operatorname{\degree}\rightarrow C=180-(30+138.19)=11.81\operatorname{\degree} \end{gathered}[/tex]So, there are two triangles that can fit the given data

Determine if the following equations are parallel, perpendicular, or neither. 5(x + 3) = 3y + 12 and 5x + 3y = 15
Answers
Solution
We have the following equation:
5(x+3)= 3y+12 (1)
Solving for y we got:
3y= -12+ 5(x+3)
3y = -12 + 5x+15
3y= 5x +3
y= 5/3 x +1
The slope for the first case is: m1= 5/3
5x + 3y = 15 (2)
Solving for y we got:
3y= 15-5x
y= 5 -5/3x
The slope is given by : m2= -5/3
Then m1*m2 is not equal to -1 (NOT perpendicular)
m1 is different from m2 (NOT parallel)
Then are not perpendicular or parallel
(−2,1) is a solution to the following system of linear equations6−3=−152+=−3
Answers
We have the following system of linear equations:
[tex]\begin{gathered} 6x-3y=-15 \\ 2x+y=-3 \end{gathered}[/tex]We want to know if the pair (x,y) = (-2,1) is a solution of the system above.
To see if this pair is a solution, we simply replace the values of x and y in the equations above and we verify if the equality holds.
1) Replacing in the first equation we see that:
6x - 3y = 6*(-2) - 3*(1) = -12 -3 = -15 ✓
The equality holds.
2) Replacing in the second equation we see that:
2x + y = 2*(-2) + 1 = -4 + 1 = -3 ✓
The equality holds.

(c) When the local time in Athens is 09 00, the local time in Berlin is 08 00.
A plane leaves Athens at 13.15
It arrives in Berlin at 1505 local time.
(i) Find the flight time from Athens to Berlin.??
Answers
Answer:
l _ to the cinema at least a week
The flight time from Athens to Berlin is 50 minutes as per the given data.
What is local time?Local time refers to the time in a specific location or time zone. It is the time that is used and observed by people in a particular region or city.
To find the flight time from Athens to Berlin, we need to calculate the time difference between the two cities and subtract it from the elapsed time between the departure and arrival times.
Athens is one hour ahead of Berlin when it is 9:00 AM in Athens, it is 8:00 AM in Berlin. This means that when the plane leaves Athens at 13:15 local time, it is 12:15 in Berlin.
The elapsed time between the departure time (13:15) and the arrival time (15:05) is 1 hour and 50 minutes.
However, we need to account for the time difference between the two cities. Since Berlin is one hour behind Athens, we need to subtract one hour from the elapsed time:
1 hour and 50 minutes - 1 hour = 50 minutes
Therefore, the flight time from Athens to Berlin is 50 minutes.

You deposit $75 in an account that earns simple interest at an annual rate of 5% . How much money is in the account after 3 years?
Answers
The account balance in the account $86.25 after 3 years by using simple interest.
What is the simple interest?
Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
The formula of the simple interest is I = PRt.
P = Principal
R = Rate of interest per year
t = time
In the given question Principal = $75, R = 5% = 0.05, t = 3 years.
I = 75 × 0.05 × 3 = 11.25
The account balance after 3 years will be sum of principal and interest.
The account balance after 3 years is = $(75 + 11.25) = $ 86.25.

Compound Interest
The Future Value of investment on compound interest can be calculated with the formula:
[tex]FV=PV(1+i)^n[/tex]Where PV is the present value or Principal, i is the adjusted interest rate and n is the number of compounding periods.
The principal is PV=$580.
The APR is 4.65% = 0.0465
The compounding period is quarterly.
Since there are 4 quarters in a year, the adjusted interest rate is:
i = 0.0465 / 4 = 0.011625.
The number of periods is n=6 years * 4 = 24 quarters
Now compute the future value:
