Find the perimeter of ATUV. Round your answer to the nearest tenth if necessary.Figures are not necessarily drawn to scale.
Explanation
To solve the question, we will first apply a similar triangle theorem
Similar triangles are triangles that have the same shape, but their sizes may vary.
so, we can compare similar sides to get x before we get the perimeter
Thus
[tex]\frac{SR}{VU}=\frac{QR}{TU}[/tex]Hence
[tex]\frac{23}{x}=\frac{20}{24}[/tex]Solving for x
[tex]\begin{gathered} x=\frac{23\times24}{20} \\ x=27.6 \end{gathered}[/tex]Thus, we will have
Then the perimeter will be:
[tex]VT+VU+TU=36+24+27.6=87.6[/tex]Therefore, the perimeter of the triangle TUV is 87.6

In the diagram, chord FG and tangent ED meet at F.
We use the theorem below:
Arc FG is the intercepted arc, therefore:

TechWiz Electronics makes a profit of $35 for each MP3 or player sold and $18 for each DVD player sold. Last week, TechWiz sold a combined total of 118 MP3 and
DVD players.
Let x be the number of MP3 players TechWiz sold last week. Write an expression for the combined total profit (in dollars) TechWiz made from MP3 and DVD
players last week.
Answer: 118=x+y z=35x+18y
Step-by-step explanation: x= the amount of MP3 players, and y= DVD Players. The 35 and 18 represent the profit for both of them, and in the first equation, the 118 shows the total amount sold. The z represents the profit made, because you are multiplying the amount of MP3 players and DVD players by their price, then adding them for the total amount.

Systems of equations converting words to equations math word promblems into systems of equationsThere were 166 paid admissions to a game. The price was $2.10 each for adults and $0.75 each for children. The amount taken in was $293.25 How many adults and how many children attended?Problem#2 on a table are 20 coins, quarters and dimes. Their value is $3.05 how many of each kind of coin are there?
Problem #1:
x = adults
y = children
x + y = 166
2.10x + 0.75y = 293.25
x = 166 - y
Now we substitute the x value on the second equation:
2.10(166 - y) + 0.75y = 293.25
And we solve for y:
y = 41.
Now we substitute the y value on the first equation:
x = 166 - 41
x = 125
There are 125 adults and 41 children

How do you know a relationship in Linear? Describe how you know based on thegraph, based on the table and based on if you have an equation.
The linear relationship must follow the general rule:
[tex]y=m\cdot x+b[/tex]where m is the slope of the linear relationship and b is called the y-intercept
if b = 0, so, it will be a proportional relationship
So, if we have a graph, the graph will be a line
The slope of the line will be = rise/run
Where rise = the difference between y-coordinates
And the run will be = the difference between x-coordinates
If we have a table, we will find the slope using two points from the table with the ordered pair (x1, y1) and ( x2, y2 ) as follows:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]The ratio must be constant between any two points from the table
Finally, if we have an equation, it must be like the general form or can be converted to the general form
In general, the linear equation has a degree of 1

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 50 milligrams of Medication A with 40 milligrams of Medication B. However this week, the doctor said to only use 16 milligrams of Medication B. How many milligrams of Medication A should be mixed this week? Answer: milligrams Question Help: D Video Read Submit Question
If by last week, your patient's doctor indicated that you should mix 50 milligrams of Medication A with 40 milligrams of Medication B, then;
A:B = 50:40
Using equality postulate, we can say;
50mg of A = 40mg of B
however if this week, the doctor said to only use 16 milligrams of Medication B, in order for us to get the amount of equivalent milligram for medication A, we will also usse the equality postulate say:
x mg of A = 16mg of B (I had to use x since we do not know the dosage of medication A)
Solving both expression to get x:
50mg of A = 40mg of B
x mg of A = 16mg of B
Simply cross multiply since both medications are always mixed in the same proportion:
40 * x = 50 * 16
40x = 800
Divide both sides by 40
40x/40 = 800/40
x = 20
Therefore 20miligram of medication A should be mixed this week
