Answer:
120
Step-by-step explanation:
The measure of the arc QR⏜ intercepted by the inscribed ∠QPR is given.
According to the Inscribed Angle Theorem, the measure of the inscribed angle is equal to one-half the measure of the arc.
m∠QPR=12mQR⏜
Substitute 60° for mQR⏜.
m∠QPR=12(60°)
Simplify.
m∠QPR=30°
The figure shows the same circle as in the beginning of the task. Triangle P R S is highlighted in red. Angle S P R measures 30 degrees.
It is given that m∠SRP=30°. Use the Triangle Sum Theorem to find the measure of the unknown ∠PSR.
m∠SRP+m∠SPR+m∠PSR=180°
Substitute the known values.
30°+30°+m∠PSR=180°
Simplify.
60°+m∠PSR=180°
Subtract 60° from both sides.
m∠PSR=120°
Therefore, m∠PSR=120°.

Answer:
i think its 320
Step-by-step explanation:
i looked it up
Answer:
320
Step-by-step explanation:
To find the total sum, divide the sum of money by the percentage.
12 1/2% = 0.125
40/0.125 = 320
Match each function with its domain. 1. S(x) = √x 2. H(x) = √2+x 3. Z(x) = √x-2 4. Q(x) = √2-x 5. V(x) = √-x 6. N(x) = ^3√2-x x ≤ 2 x ≥ -2 x ≥ 0 x ≥ 2 x ≤ 0 All real numbers
Answer:
1. x ≥ 0
2. x ≥ -2
3. x ≥ 2
4. x ≤ 2
5. x ≤ 0
6. All real numbers
Step-by-step explanation:
Domain of square function:
Suppose we have a square function in the following format:
[tex]f(x) = \sqrt[n]{g(x)}[/tex]
If n is even, the domain of f(x) is:
[tex]g(x) \geq 0[/tex]
Otherwise, if n is odd, the domain of f(x) is all real numbers.
1. S(x) = √x
If n does not appear is that it is 2.
g(x) = x
So the domain is:
[tex]x \geq 0[/tex]
2. H(x) = √2+x
g(x) = 2 + x
So
[tex]2 + x \geq 0[/tex]
[tex]x \geq -2[/tex]
3. Z(x) = √x-2
g(x) = x - 2
[tex]x - 2 \geq 0[/tex]
[tex]x \geq 2[/tex]
4. Q(x) = √2-x
g(x) = 2 - x
[tex]2 - x \geq 0[/tex]
[tex]-x \geq -2[/tex]
Multiplying by -1, everything
[tex]x \leq 2[/tex]
5. V(x) = √-x
g(x) = -x
Then
[tex]-x \geq 0[/tex]
Multiplying by -1
[tex]x \leq 0[/tex]
6. N(x) = ^3√2-x
Cubic root(odd number), so all real numbers.
find the values for a and b.
Answer:
the value of a and b is 68
Step-by-step explanation:
the other half is 224 so you minus 360 from 224 which will give us 136 then you divide by 2 to get a and b.
Answer:
a = 68, b = 136
Step-by-step explanation:
The angle in the circle = 360°, thus
b = 360 - 224 = 136
The inscribed angle a between a tangent- chord is equal to half the measure of its intercepted arc, so
a = 0.5 × 136 = 68
Two Parallel lines are cut by a transversal and form a pair of alternate exterior angles. One angle measures (6x+5) and other measures (7x+4). Explain how to determine what those other angles actually measure.
Answer:
The other angles will measure 83.9° and 96.1°Step-by-step explanation:
If two parallel lines are cut by a transversal and form a pair of alternate exterior angles, then the sum of the two exterior angles will be equal to 180° as shown;
If one angle measures (6x+5) and other measures (7x+4), then;
(6x+5)+(7x+4) = 180° (sum of two exterior angles)
Firstly, lets get the value of x from the equation.
6x+7x+9 = 180°
13x= 180-9
13x = 171
x = 171/13
x = 13.15°
The first angle 6x+5 will measure 6(13.15)+5 = 83.9°
The other angle 7x+4 will mesure 7(13.15)+4 = 96.1°
Answer:
Since the lines are parallel, the alternate exterior angles are congruent. Therefore you can set the expressions equal to each other and solve for x. Then you can substitute the value of x back into either expression to find the angle measure.

What is the value of \cos(\theta_1)cos(θ 1 )cosine, (, theta, start subscript, 1, end subscript, )?
Answer:
[tex]\cos(\theta_1)=-\dfrac{\sqrt{15}}{4}[/tex]
Step-by-step explanation:
The angle [tex]\theta_1[/tex] is located in Quadrant II.
[tex]\sin(\theta_1)=\dfrac{1}{4}[/tex]
From trigonometry, we know that:
[tex]\sin(\theta)=\dfrac{Opposite}{Hypotenuse}\\$Therefore:\\Opposite=1\\Hypotenuse=4\\Using Pythagorean theorem:\\Hypotenuse^2=Opposite^2+Adjacent^2\\4^2=1^2+Adjacent^2\\Adjacent^2=16-1\\Adjacent^2=15\\Adjacent=\sqrt{15}[/tex]
Now, in Quadrant II,
The x-axis is negativeThe y-axis is positiveTherefore, the Adjacent angle to [tex]\theta_1 =-\sqrt{15}[/tex]
Therefore:
[tex]\cos(\theta_1)=\dfrac{Adjacent}{Hypotenuse}=\dfrac{-\sqrt{15}}{4}\\\\\cos(\theta_1)=-\dfrac{\sqrt{15}}{4}[/tex]
Mel's Furniture received an invoice dated September 27 for 5 bedroom sets at $3,000 each. The invoice indicated a chain discount of 5/8/3. The seller of the furniture prepaid the freight of $200 (FOB Shipping Point). Terms were 2/10, EOM. Assuming that Mel pays within the discount period, what is the total payment amount?
Answer: $12,916.70
Step-by-step explanation:
Given the following:
Invoice received :
Bedroom set = 5
Cost per set = $3,000
Chain discount = 5/8/3
Freight cost = $200
If Mel pays within the discount period:
Chain discount given = 5/8/3
Therefore, net equivalent price rate equals:
(1 - 0.05) × (1 - 0.08) × (1 - 0.03) =
0.95 × 0.92 × 0.97 = 0.84778
Net price = total cost × 0.84778
($3000 × 5) × 0.84778
$15000 × 0.84778 = $12,716.7
Net equivalent price + FOB Shipping
$12,716.7 + $200 = $12,916.70

Answer:
2,3,5,6
Step-by-step explanation:
How can I solve this problem?
a) 108°
Answer:
b) 54°
Step-by-step explanation:
a) By arc sum property of a circle.
[tex] m\widehat {AEB} + m\widehat {AB} = 360°\\
252° + m\widehat {AB} = 360°\\
m\widehat {AB} = 360°- 252°\\
\huge \red {\boxed {m\widehat {AB} = 108°}} \\[/tex]
b) In the given figure, DC is tangent to the circle with O at point A and AB is chord or secant. Therefore, by tangent secant theorem:
[tex] m\angle BAC = \frac{1}{2} \times m\widehat {AB}\\\\
\therefore m\angle BAC = \frac{1}{2} \times 108°\\\\
\huge \purple {\boxed {m\angle BAC = 54°}} [/tex]

which set of angles has the same terminal arm as 70 degrees?
Answer: B = B ∈ {70° + n*360° I n ∈ Z } where Z is the set of the integer numbers.
Step-by-step explanation:
If we have an angle A, the other angles that have the same terminal arm than A can be written as:
B = A + n*360°
Here B is a "coterminal" angle to A. (they have the same terminal side)
where n can be any integer number (if n = 0 we have A = B, which is trivial, this means that any angle can be coterminal with itself.)
So we can write the set as:
B = B ∈ {70° + n*360° I n ∈ Z }
The set of angles that has the same terminal arm as 70 degrees is B = B ∈ {70° + n*360°, n ∈ Z}.
We have to determine, which set of angles has the same terminal arm as 70 degrees.
According to the question,
Let, The angle A and other angle B that have the same terminal arm as A can be written as,
B = A + n × 360°
Where the value of angle A is 70 degrees.
B is the coterminal angle, and they have the same terminal,
And n is the number of integers.
Substitute the value of A in the equation,
B = 70 + n × 360°
Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.
Since the value of n is equal to 0 then A = B,
Therefore, The angles coterminal with itself is called trivial.
Hence, The set of angles that has the same terminal arm as 70 degrees is B = B ∈ {70° + n*360°, n ∈ Z}.

Richard drives his car for 5 hours.
His average speed is 30 mph.
(a) How far does Richard travel?
miles
Richard drives 560 km the next day.
(b) Work out how much further Richard travelled, compared to the previous day.
5 miles = 8 kilometers
miles
Answer:
A. 150 miles
B. 200 miles further
Step-by-step explanation:
Multiply 30 by 5 to find how far he traveled the first day
30 x 5 = 150 miles
For the second day, convert km to miles by making a proportion
[tex]\frac{5}{8}[/tex] = [tex]\frac{x}{560}[/tex]
x = 350 miles
Then, to find the difference, subtract the 350 - 150 = 200
