The first step to solve this problem is to calculate the missing angle that has its vertex on P. The sum of the internal angles on every triangle is equal to 180 degrees, since we have the other two angles we can calculate the missing one as shown below:
[tex]\begin{gathered} 48+35+\measuredangle P=180 \\ 83+\measuredangle P=180 \\ \measuredangle P=180-83 \\ \measuredangle P=97 \end{gathered}[/tex]The angle is equal to 97 degrees. Now we know all the measurements of all the angles and sides of this triangle. When a triangle is rotated its measurements don't change, this means that if a side is equal to 2 before the rotation it should also be equal to 2 after the rotation. With this in mind we can say that:
The length of the side P'Q' is 9 units and the measurement of the angle P' is 97 degrees.

Answers
The epson stylus 850 can print Helen's project in 12 mins
TThe epson stylus 500 can print that same project in 42 minutes
Work = rate x time
the two printers are working on the same assignment
therefore, we will be adding their rate
for epson 850
work = rate x time
work= 1
time = 12mins
1 = rate x 12
make rate the subject of the formula by dividing bott sides by 12
1 / 12 = rate x 12 / 12
rate = 1/ 12
for epson 500
work = rate x time
time = 42 mins
work = 1
applying the same process
1 = rate x 42
rate = 1/42
since they are both working together
Total rate = 1 /12 + 1/42
lcm is 84
since 12 and 42 are factors of 84
Total rate = 1/12 + 1/42
total rate = 84 * 1 /12 + 84*1 / 42 /84
total rate = 7 + 2 / 84
total rate = 9/84
to calculate the time they worked together
work = rate x time
1 = 9/84 x time
make time the subject of the formula
1 / 9/84 = time
time = 84/9
time = 28 / 3
Time = 9 1/3 min

A 6 3/4-inch candle burns down in 9 hours. How far has it burned after 6 hours? Use the dropdown menu to state your answer as a decimal, mixed number, or improper fraction.
Answers
The question can be solved using fractions, 4 and 1/2 inches of the candle will burn in 6 hours.
What is fractions?
The components of an entity or group of entities are represented as fractions. A fraction consists of two components. The numerator is the number at the top of the line (slash). It tells us how many equal portions of the whole or collection were taken. The denominator is the figure that appears below the line (slash). It displays the total number of identical objects in a collection or the total number of equal portions.
As given in the question, 6 3/4-inch (27/4) inch candle burns down in 9 hours.
We have to find the candle burnt in 6 hours.
Fraction for 9 hours = Fraction for 6 hours
So,
27/4:9 = x:6
We can also write it as,
(27/4)9 = x/6
x = 4.5 inch
It could also be written as 4 1/2 inches.

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.
Answers
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.

[tex]\begin{gathered} D=\sqrt{(0+3)^2+(-4-2)^2} \\ D=\sqrt{45} \\ D=6.71\text{ units} \end{gathered}[/tex]And, the side length YZ is-
[tex]\begin{gathered} D=\sqrt{(3-0)^2+(2+4)^2} \\ D=\sqrt{45} \\ D=6.71\text{ units} \end{gathered}[/tex]Finally, the side length WZ is-
[tex]\begin{gathered} D=\sqrt{(3-0)^2+(2-5)^2} \\ D=3\sqrt{2} \\ D=4.24\text{ units} \end{gathered}[/tex]Now, since the adjacent sides of the quadrilateral WXYZ are equal, the quadrilateral is a Kite.
Final Answer:
The length of side WX=4.24 units.
The length of side XY=6.71 units.
The length of side YZ=6.71 units.
The length of side ZW=4.24 units.

1) Gathering the data
∠3 = 5x -1
∠5=3x +11
∠3=?
2) The angles ∠3 and ∠5 are alternate interior angles, therefore they are congruent ones. So we can write:

b. If copies of all your computer data are stored on independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
Answers
The probability that at least one drive is working is 0.99 and the probability that at least one drive is working out of 3 drives is 0.999 .
Probability is the branch of mathematics which deals with the likelihood of an occurrence of an event.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's true probability is a single decimal number between 0 and 1, where, mathematically speaking, 0 denotes the event is impossible and 1 denotes certainty.
Given the probability on one disk failing is 0.1
Probability that both disk fails = 0.1 × 0.1 = 0.01
Now let us calculate the probability that at least one disk does not fail.
We have to find the complement of the above.
Required probability = 1 -0.01 = 0.99
Similarly when 3 independent disc are involved.
Probability that all the disc fails = 0.1 × 0.1 × 0.1 = 0.001
At least one survives = 1 - 0.001 = 0.999
Therefore the probability that at least one drive is working is 0.99 and the probability that at least one drive is working out of 3 drives is 0.999 .
