Since the triangles are similar this means that the ratios between similar sides have to be equal; this means that:
[tex]\begin{gathered} \frac{6.5}{3.6}=\frac{5.2}{y} \\ \frac{6.5}{3.6}=\frac{a}{4.5} \end{gathered}[/tex]Solving the first equation we have:
[tex]\begin{gathered} \frac{6.5}{3.6}=\frac{5.2}{y} \\ y=\frac{5.2}{\frac{6.5}{3.6}} \\ y=2.88 \end{gathered}[/tex]Solving the second equation:
[tex]\begin{gathered} \frac{a}{4.5}=\frac{6.5}{3.6} \\ a=4.5(\frac{6.5}{3.6}) \\ a=8.125 \end{gathered}[/tex]Therefore, a=8.125 and y=2.88

Answers
The graph is based on amplitude.
Given the function:
f(t) = 5sin3t
To draw the graph of above function.
The function g(t) = sin t is a periodic function with amplitude [tex]a_{0}[/tex] = 1 and period [tex]t_{0}[/tex] = 2[tex]\pi[/tex]
For our case, the 5 that multiplies g (t) increases the amplitude so that,
a = 5 x 1 = 5 and the 3 that multiplies the variable increases the period being t = 2[tex]\pi[/tex] x 1/3 = 2[tex]\pi[/tex]/3

Answers
Given:
Vic bought a new plasma TV for $2400.
He made a down payment of $100 and then financed the balance through the store.
The interest per month is 4% on the balance.
To find:
Vic's monthly interest payment.
Explanation:
The cost of a plasma Tv is $2400.
The down payment made is $100.
Balance amount for financing is $2400 - $100 = $2,300.
Since the interest rate is 4% per month
So, the monthly interest payments will be,
[tex]2300\times\frac{4}{100}=92[/tex]The monthly interest payments will be $92.
Final answer:
The monthly interest payments will be $92.

Show work?
Answers
Answer:

Step-by-step explanation:
so first what you want to do is that you want to add $7 with 4.25 dollars plus 1.99 dollars the next thing you want to do is take 85% of this number you will get 0.85 times that sum
that sum is 13.24. now because she is getting 15% off of her purchase that means you want to take 85% of that 13.24 number . so you will get 1 1.254 you will need to round this because it is in dollars . so you will get 11.25 as her purchase price . now because she gave a $20 bill you need to subtract that number from 20 and you will get 8.746 which is rounded to 8.74 because it is in dollars that is the answer that is her change

Answers
ANSWER
x = -2, y = 7, z = 2
EXPLANATION
We are given a system of three equations:
2x + 3y - 4z = 9 ________(1)
4y - 6z = 16 ___________(2)
z = 2 ________________(3)
Since we have been given the value of z, from (3) we have that (2) becomes:
4y - 6(2) = 16
4y - 12 = 16
4y = 12 + 16 = 28
y = 28 / 4
y = 7
Put the values of y and z in (1):
=> 2x + 3(7) - 4(2) = 9
2x + 21 - 8 = 9
2x + 13 = 9
Collect like terms:
2x = 9 - 13 = -4
x = -4 / 2
x = -2
So, x = -2 and y = 7 and z = 2

If lines a and b are parallel, what is the value of x?
Answers
============================================================
Explanation:
Let y be the angle just to the left of angle x. Angle x and angle y are adjacent.
Since line a is parallel to line b, this means y = 120 because the 120 degree angle and angle y are alternate interior angles.
Then we can say:
x+y = 180
x+120 = 180
x = 180-120
x = 60
--------------
An alternative method:
Let w be the angle just above angle x
The angle marked "120 degrees" and angle w are corresponding angles. They are congruent if and only if line a is parallel to line b.
This makes w = 120
Solving w+x = 180 leads to x = 60 similar to the previous set of steps.
--------------
Side note:
The 115 degree angle is never used. It was probably put in there as a distraction.

Given that:-
Total number of students = 30

Total number of students in Physics = 12
Total number of students in Algebra = 19
We have to find the number of students which are either in algebra or physics.
Number of students in physics but not in algebra = 12 - 4 = 8
Number of students in algebra but not in physics = 19 - 4 = 15
We know that:-
Number of students which are either in algebra or physics = Number of students in physics but not in algebra + Number of students in algebra but not in physics
