Given: SQ and TQ trident angle PQR
measure of angle PQT = 7x+6
measure of angle TQS = -2x +8y-13
measure of angle RQS = 5x +2y
find measure of angle PQR
Answer:
[tex]10x+10y-7[/tex]
Step-by-step explanation:
We just need to add up all of the angles, PQT, TQS, and RQS to find the measure of angle PQR.
[tex]PQT=7x+6\\TQS=-2x+8y-13\\RQS=5x+2y\\PQT+TQS+RQS=PQR\\7x+6+TQS+RQS=PQR\\7x+6+(-2x+8y-13)+RQS=PQR\\7x+6+(-2x+8y-13)+5x+2y=PQR\\7x+6-2x+8y-13+5x+2y=PQR\\7x-2x+5x+8y+2y+6-13=PQR\\5x+5x+8y+2y+6-13=PQR\\10x+8y+2y+6-13=PQR\\10x+10y+6-13=PQR\\10x+10y-7=PQR[/tex]

Answer:
123°
Step-by-step explanation:
Each of the parts of the trisected angle is equal to the others.
∠PQT = ∠TQS
7x +6 = -2x +8y -13
9x -8y +19 = 0 . . . . . . subtract the right-side expression
∠TQS = ∠RQS
-2x +8y -13 = 5x +2y
7x -6y +13 = 0 . . . . . . subtract the left-side expression
__
These equations can be solved by any of your favorite methods to give ...
(x, y) = (5, 8)
Then the angle measures are ...
∠PQT = 7x +6 = 7(5) +6 = 41
∠TQS = -2x +8y -13 = -2(5) +8(8) -13 = 64 -23 = 41
∠RQS = 5x +2y = 5(5) +2(8) = 41
The measure of angle PQR is 3·41° = 123°.
_____
Additional comment
Using Cramer's rule, the solution is ...
x = (-8(13) -(-6)(19))/(9(-6) -7(-8)) = 10/2 = 5
y = (19(7) -13(9))/2 = 16/2 = 8
I prefer a method like this, or the graphical solution, when the numbers don't lend themselves to substitution or elimination.
__
Obviously, once we have found angle PQT, we can simply multiply it by 3 to find angle PQR. We chose to compute the values of the other angles as a check on our math.

Answer:
3²-5
Step-by-step explanation:

3²-5=4
Answer:
D
Step-by-step explanation:
First off, lets simplify (3-2^2)+5 = -1+5 = 4
We will need to find an expression that will equal to 4
lets try 1, 5-2^2 = 1, 1 =\ 4
Alright, lets try 2, 2^2 -5 = -1, -1=\5
Now lets try 3, 5 - 3^2 = -4, -4=\4
So by process of elimination we can say that D is correct by I will show you why it is correct. 3^2 -5 = 4, 4=4

(01.01 LC)An athlete took forward and backward steps of equal distance to warm up before his race. After taking 10 steps total, he was back at his starting position. How many steps did the athlete take in the forward and backward directions?
I would love the help.
9514 1404 393
Answer:
5 steps forward5 steps backwardStep-by-step explanation:
In order for the total displacement to be zero, the amount of forward displacement must be equal and opposite to the amount of backward displacement. Since the steps are the same length, they must be equal in number.
Half of the 10 steps were forward, and the other half were backward.
5 steps forward; 5 steps backward.

Additional comment
Math develops from an effort to model the real world. It would probably give you some insight into this problem if you were to physically take some steps to see how many forward and backward you would need to end where you start.

Explain why a set of points that defines a plane cannot be collinear
Answer:
Three non-collinear points determine a plane.
Step-by-step explanation:
This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is

We're planning to enclose a rectangular field with fencing, and we know that for whatever reason we want the field to be 50 feet square. We also know that the field's width should be 23 feet longer than the field's length. What are the field's dimensions?
Answer:
[tex]? \times \frac{?}{?} [/tex]
d
Answer:
2 by 25 feet.
Step-by-step explanation:
Let L and W be the length and the widht of the field
we want W = L + 23 and W x L = 50
So
(L + 23) x L = 50
[tex]L^2 + 23L = 50\\L^2+23L-50 =0\\(L+25)(L-2)=0\\L=-25 \text{ or } L = 2[/tex]
Since L must be positive then L =2 and W = 2 + 23 = 25.
The ratio of qualified teachers to unqualified teachers is 1;2. Use the given ratio and determine how many qualified teachers there are if there are 540 unqualified teachers. show your calculations
Answer:
270
Step-by-step explanation:
by using the proportion rule:
let X be the number of qualified teachers then
1:2=X=540 i.e.
1/2 = X/540
by cross multiplication,
540x1=2xX
540=2X i.e.
X=540/2
X=270
There are 270 qualified teachers.
To solve this, we would apply the knowledge of proportion.
It is simply a way of stating that two ratios are of equal measure.
For example, [tex]a:b = x:y[/tex] or [tex]\frac{a}{b} = \frac{x}{y}[/tex]
Applying the following proportion rule given that:
Ratio of qualified teachers to unqualified teachers is 1:2.
Number of unqualified teachers = 540
Let number of qualified teachers be represented by x.
Therefore:
[tex]\frac{1}{2} = \frac{x}{540}[/tex]
Cross multiply
[tex]2x = 540(1)[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} = \frac{540}{2} \\x = 270[/tex]
Therefore, the number of qualified teachers is 270.

Answer:
The monthly net pay is [tex]\$1555[/tex].
Step-by-step explanation:
Step 1 :
Quintina decided to increase the deduction percentage of her federal income tax rate from [tex]14\%[/tex] to [tex]16\%.[/tex]
Quintina gross pay per month is [tex]\$2,100[/tex]
[tex]16\%[/tex] is written in the decimal form.
[tex]=\frac{16}{100}[/tex]
[tex]=0.16[/tex]
Federal income tax
[tex]=0.16[/tex] × Gross pay
[tex]=0.156[/tex] × [tex]2100[/tex]
[tex]=336[/tex]
Step 2:
Monthly net pay = Gross pay- Federal income tax - State Income Tax – social Security- Medicare.
[tex]=2100-336-89-85-35[/tex]
