Answer:
m∠DEF = 127°
Step-by-step explanation:
Length of arc is double the inscribed angle formed by two chords or secants meeting at a point on the circle,
By this property,
Measure of Inscribed angle ∠DEF = [tex]\frac{1}{2}(arc FGD)[/tex]
(6x + 37) = [tex]\frac{1}{2}(19x-31)[/tex]
12x + 74 = 19x - 31
19x - 12x = 74 + 31
7x = 105
x = 15
Therefore, m(∠DEF) = 6(15) + 37
= 90 + 37
= 127°
Solve the equation. 6x−7=2x+13
Answer:
6x - 7 = 2x + 13
6x - 2x = 13 + 7
4x = 20
x = 20/4
x = 5

Determine in which direction the parabola below opens.
y=x2-7x + 18
Answer:
upwards
Step-by-step explanation:
Whether a parabola opens upwards or downwards depends on "a". (A as in ax^2+bx+c). If A is greater than zero it opens upwards. Less than zero it opens downwards. In this case, A is one so it opens up

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.
Answer:
a = 1.4 and d = 6.9
Step-by-step explanation:
To get the value of d and a, we will use the SOH CAH TOA identity
For the first tringle;
Opposite = d ((opposite angle 60 degrees)
Adjacent = 4
Tan theta = opp/adj
Tan 60 = d/4
d = 4tan60
d = 4(1.732)
d = 6.9
For the second triangle;
Opposite = a
Hypotenuse = 2
Since sin theta = opp/hyp
Sin45 = a/2
a = 2sin45
a = 2(0.7071)
a = 1.4
Hence a = 1.4 and d = 6.9

What is the angle VXU?
Plzzz help
Answer:
∠ VXU = 105°
Step-by-step explanation:
the chord- chord angle VXU is half the sum of the arcs intercepted by the angle and its vertical angle.
The sum of the arcs in a circle = 360° , so
UV = 360° - (130 + 60 + 90)° = 360° - 280° = 80°
Then
∠ VXU = [tex]\frac{1}{2}[/tex] (80 + 130)° = 0.5 × 210° = 105°

good afternoon
When an item is marked down 10% , why does it make sense to multiply the price by 0.9?
Answer:
Since there is 10% off of the price, the new cost is 90% of the original. So we just multiply the price by 0.9
Help plz

solve for x, find the simplified radical & decimal
Answer:
x = 6[tex]\sqrt{2}[/tex] = 8.485
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is [tex]\sqrt{2}[/tex] times the length of a leg.
So, if you are given the hypotenuse, then divide its length by [tex]\sqrt{2}[/tex]
x = 12/[tex]\sqrt{2}[/tex] = 12[tex]\sqrt{2}[/tex]/2 = 6[tex]\sqrt{2}[/tex] = 8.485
What is the measure of angle Q?
Answer:
hi
Step-by-step explanation:
x⁰+(x+90)⁰+(x-18)⁰=180⁰
3x+72=180
3x=180-72
3x=108
x=36
Q is equal to x+90=36+90=126
For cheking answer:
R is 36
Q is 126
P is 18
36⁰+126⁰+18⁰=180⁰
hope it helps
have a nice day
Answer:
[tex]x=96[/tex]
Step-by-step explanation:
[tex]360=x+\left(x+90\right)+\left(x-18\right)[/tex]
Step 1: Simplify both sides of the equation.
[tex]360=x+x+90+x-18[/tex]
[tex]360=(x+x+x)+(90+-18)[/tex] (Combine Like Terms)
[tex]360=3x+72[/tex]
Step 2: Flip the equation.
[tex]3x+72=360[/tex]
Step 3: Subtract 72 from both sides.
[tex]3x+72-72=360-72[/tex]
[tex]3x=288[/tex]
Step 4: Divide both sides by 3.
[tex]\frac{3x}{3}=\frac{28}{3}[/tex]
[tex]x=96[/tex]
Hope this helped! :)
In problem 8-94 you found that if you are given three lengths to build the sides of a triangle, then if a triangle can be formed, all the triangles you could make were the same. Suppose you start with two triangles knowing that their three pairs of corresponding sides are the same, as shown in the diagram below.
Triangle, A B C, where side, A C, has one hatch mark, side, C B, has 2 hatch marks, and side, A B, has 3 hatch marks.
Triangle, P Q R, where side, R P, has one hatch mark, side, P Q, has 2 hatch marks, and side, R Q, has 3 hatch marks.
Examine the diagram. What do you think the markings indicate? Name the pairs of corresponding sides.
What can you say about the two triangles and why? What can you say about their angles? Why?
One earthquake has MMS magnitude 3.9. If a second earthquake has 120 times as much energy (earth movement) as the first, find the magnitude of the second quake.
Answer:
The right answer is "5.9". A further solving is provided below.
Step-by-step explanation:
The given values are:
Initial Magnitude,
M₁ = 3.9
Let Second magnitude be M₂.
Now,
⇒ [tex]M_2-M_1=log(\frac{l_2}{l_1} )[/tex]
On substituting the values, we get
⇒ [tex]M_2-3.9 = log (120)[/tex]
On putting the value of "log 120", we get
⇒ [tex]M_2-3.9=2.079[/tex]
On adding "3.9" both sides, we get
⇒ [tex]M_2-3.9+3.9=2.079+3.9[/tex]
⇒ [tex]M_2=5.9[/tex]
The ordered pair (a, b) gives the location of point P on the coordinate plane. The value of b is negative. The value of a is not 0. Where could point P be located on the coordinate plane? Choose all answers that apply: Choice A Quadrant I (Choice B) Quadrant II (Choice C) Quadrant III (Choice D) Quadrant IV (Choice E) x-axis (Choice F) y-axis
Answer:
Quadrant III ( C )
Quadrant IV ( D )
Step-by-step explanation:
Ordered pair ( a, b )
gives a point P on the coordinate plane
( a, b ) = ( x, y )
given : b = negative ( y-axis )
a ≠ 0 ( i.e. a = negative or positive ) ( x -axis )
Therefore point P is located in the : Third and fourth quadrants

3 of the digits 0-9 are chosen randomly by a computer what is the probability that it will choose 3 sequential digits
Answer:
The probability is 1/15
Step-by-step explanation:
Firstly, we need to get the total
number of possible choices
That will be selecting any random 3 numbers from 10 numbers
The number of ways this can be done is 10 C 3 = 120 ways
Now, let us get the possible sequential numbers;
These are ;
0 1 2
1 2 3
2 3 4
3 4 5
4 5 6
5 6 7
6 7 8
7 8 9
Out of the total 120 ; there are 8 possible sequential digits
The probability in this case is thus;
8/120 = 1/15
what is the difference between the solution you get when solving an equation and the solution you get when solving an inequality
Answer:
If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses. !!!!!
Step-by-step explanation:
Answer:
The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Mr. Palmer deposited $850 into a simple interest account for 8 years, earning at an 8% interest rate. What will his total balance be when he checks it?
I DO NOT WANT A LINK!!!!!!!!
Answer:
solution given:
principal [P]=$850
time[T]=8years
rate[R]=8%
now
simple interest [S.I.]=[tex] \frac{P×T×R}{100}[/tex] =$ [tex] \frac{850×8×8}{100}[/tex] =$544
so
Total balance=S.I.+P=$544+$850=$1394.

Answer:
2∠15°2cos(15°) +i·2sin(15°) ≈ 1.93185 +0.517638iStep-by-step explanation:
Using Euler's formula, the 6th root is easily found.
(64i)^(1/6) = ((2^6)e^(iπ/2))^(1/6) = 2e^(iπ/12) = 2∠15°
= 2(cos(15°) +i·sin(15°)) = 2·cos(15°) +i·2·sin(15°) ≈ 1.93185 +0.517638i
What value of x makes the following equation true? ( 8th grade math )
Answer: 4
Step-by-step explanation:
2(x+7) = x + 18
2x + 14 = x + 18
x + 14 = 18
x = 4
Answer:
C. 4
Step-by-step explanation:
[tex]2(x + 7) = x + 18[/tex]
[tex]2(x+7) = 2x + 2×7[/tex]
[tex]=2x+14[/tex]
[tex]2x + 14 = x + 18[/tex]
[tex]2x + 14-x=18[/tex]
[tex]2x - x = 18 - 14[/tex]
[tex]x=18-14[/tex]
[tex]x = 4[/tex]
