Answers
Answer:
Did not multiply the numerator by the radical
Explanation:
The hypotenuse of a 45-45-90 triangle is equal to the leg times √2.
In this case, the leg is x and the hypotenuse is 6, so we have the following equation
hypotenuse = leg √2
6 = x √2
To solve for x, we get
[tex]\begin{gathered} x\sqrt{2}=6 \\ \\ x=\frac{6}{\sqrt{2}} \end{gathered}[/tex]Then, we need to multiply the numerator and denominator by √2, so
[tex]x=\frac{6}{\sqrt{2}}\cdot\frac{\sqrt{2}}{\sqrt{2}}=\frac{6\sqrt{2}}{(\sqrt{2})^2}[/tex]Therefore, the solution is equal to
[tex]x=\frac{6\sqrt{2}}{2}=3\sqrt{2}[/tex]Therefore, the error in the process was that they did not multiply the numerator by the radical

Answers
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:
[tex]FV=580(1+0.011625)^{24}[/tex]Calculating:
[tex]\begin{gathered} FV=\$580\cdot1.31968 \\ FV=\$765.42 \end{gathered}[/tex]The future value is $765.42 and the present value is $580, so the interest is:
I = $765.42 - $580
I = $185.42

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.

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.

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
So, the answer will be Two
