The angle is in between 50° and 60°
Answer:
55°
Step-by-step explanation:
One ray lies on the 0° mark and the other lies on the 55° mark. To find the measure of the angle, find the difference between the greater angle and the lower angle. 55° - 0° = 55°

The length which result in a ratio closest to the golden ratio is equal to 7.5 inches and 4.5 inches. Option C is correct.
What is the length of line segment?The line segment is made with two end points. Length of a line segment is the distance of both the ends of it.
A 12 inch line segment is divided into two parts. Suppose the line segment is AC which is divided into AB and BC parts. Thus,
AB+BC=AC
AB+BC=12 ....1
The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2. The ratio of both segment is equal to golden ratio. Thus
[tex]\dfrac{AB}{BC}=\dfrac{AC}{AB}=\dfrac{1+\sqrt{5}}{2}\\\dfrac{12}{AB}=1.618\\AB=7.4166 \rm\; in[/tex]
Put this value in equation one as,

In a certain Algebra 2 class of 21 students, 10 of them play basketball and 9 of them
play baseball. There are 8 students who play neither sport. What is the probability
that a student chosen randomly from the class plays both basketball and baseball?
Step-by-step explanation:
out of the 21 students, 8 do not play neither basketball nor baseball.
so, 13 students play at least one of these games.
10 play basketball, and 9 play baseball. that would be 19 together. but we have only 13 players.
that means 6 students (19 - 13) must play both games.
remember, a probability is always
desired cases / possible cases
so, when we are looking for the students, who play both games, we have 6 desired cases out of a total of 21.
and the probability to pick one of them is therefore
6/21 = 2/7 = 0.285714286...

add the numbers 197,203 and 423 in two ways fast
Answer:
823
Method 1
Break the three numbers into hundreds, tens and units, then add these separately (starting with the units)
197 = 1 hundred, 9 tens, 7 units
203 = 2 hundreds, 0 tens, 3 units
423 = 4 hundreds, 2 tens, 3 units
Units: 7 + 3 + 3 = 13
Tens: 9 + 2 = 11 tens = 110
Hundreds: 1 + 2 + 4 = 7 hundreds = 700
Add these together: 700 + 110 + 13 = 823
Method 2
First add 203 to 197:
Borrow the 3 from 203 and add it to 197: 197 + 3 = 200
Add the remaining 200: 200 + 200 = 400
Now add 423 to 400: 400 + 423 = 823
⇒ 203 + 197 + 423 = (203 + 197) + 423
= 400 + 423
= 823

Contestants in a game show are each given three pairs of numbers (for example, 2 and 3, 5 and 6, and 6 and 1). a person in the audience is randomly picked and asked to roll two dice, one white and one red. the white die gives the first number in the pair, and the red die gives the second number. the probability that each player has of winning is .
The game is an illustration of probability, and the probability that each player wins is 1/12
How to determine the probability of winning?From the question, we have the following parameters:
Number of a pair of numbers = 3
A die has 6 possible outcomes.
So, the probability of getting the first pair is:
P1 = 1/6
The probability of getting the second pair is:
P2 = 1/6
The probability of getting the first and the second pairs is
P = 1/6 * 1/6
Evaluate
P = 1/36
There are three pairs of numbers in total.
So, the probability of winning is:
P(Win) = 3 * 1/36
Evaluate
P(Win) = 1/12
Hence, the probability that each player wins is 1/12

Which graph correctly represents the relationship between arc length and the measure of the corresponding central angle on a circle with radius r?
Any smooth curve connecting two points is called an arc. The correct option is c.
What is the Length of an Arc?Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]
where
θ is the angle, that arc creates at the centre of the circle in degree.
If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.
Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is 2π(360°), then the length of the arc will be 2πr.
Hence, the correct option is c.

A town has a population of 4.11 x 104 and shrinks at a rate of 9.6% every year.
Which equation represents the town's population after 4 years?
Answer:
59304
Step-by-step explanation:
4.11x 10⁴=41100, 9.6 =( 1+9.6/100)=1.096
x(n)−population after n years
x(n)=x(0)×1.096^n=41100x1.096^n
x(4)=41100×1.096⁴=59304.007
= 59304
An equation represents the town's population after 4 years is [tex]x(4)=4.11\times10^4(1+\frac{9.6}{100})^4[/tex].
Given that, a town has a population of [tex]4.11\times10^4[/tex] and shrinks at a rate of 9.6% every year.
What is population growth and population decrease formula?If a constant rate of growth be R% per annum, then population after n years = [tex]P(1+\frac{R}{100} )^n[/tex]
Now,
[tex]x(4)=4.11\times10^4(1+\frac{9.6}{100})^4[/tex]
⇒ [tex]x(4)=4.11\times10^4(1+0.096)^4[/tex]
⇒ [tex]x(4)=41100\times(1.096)^4[/tex]
⇒ x(n)=41100×1.443
⇒ x(n)=59307.3

In trapezoid PQRS, PQ is parallel to SR. What is the area of PQRS in simplest radical form?
The area of the considered trapezoid PQRS in simplest radical form is given by: Option c: 256 + 128√3 (in sq. units)
How to find the area of a trapezoid?The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).
Thus, if we have:
Length of its parallel sides = 'a' and 'b' units respectively
Perpendicular distance between its parallel sides = 'h' units,
Then, we get:
[tex]A = \dfrac{1}{2}\times(a+b) \times h \: \rm unit^2[/tex]
Consider the figure attached below, which is a bit more labeled figure of the given trapezoid.
We constructed PA perpendicular to the level of SR, and therefore, as SR is parallel to PQ, we have PA perpendicular to PQ too.
Similarly, QB is constructed perpendicular to both PQ and SR.
Thus, for PQBA, all pair of adjacent sides are perpendicular to each other, therefore its a rectangle.
Sum of parallel sides = Length of PQ + Length of SR
= 24 + |SR| = 24 + |SB| + |BR| = 24 + |AS| - |AS| + |SB| |+ |BR|
= 24 + |AS| + |SB| + |BR| - |AS| = 24 + |AB| + |BR| - |AS|
Due to PABQ being a rectangle (its four sides are such that adjacent sides are perpendicular to each other), we have |PQ| = |AB| = 24 units.
Thus, we get:
Sum of parallel sides = 24 + |AB| + |BR| - |AS| = 48 + |BR| - |AS|
Perpendicular distance between its parallel sides = |PA| = |QB|
Thus, we need to find the values of 3 line segments, which are:
|BR|, |AS|, and |PA| (instead of |PA|, we can find |QB| too, since both are of same length).
Case 1: Finding the length of BR:From the perpective of angle R(interior) in right triangle RBQ, we know the side RQ's length (32 units), and want length of BR.
Thus, its hypotenuse and base from the perspective of angle R (interior).
Thus, we can use cosine ratio or secant ratio. Let we use cosine ratio.
Then, we get:
[tex]\cos(30^\circ) = \dfrac{|BR|}{|RQ|} \\\\|BR| = 32 \times \cos(30^\circ) = 32 \times \dfrac{\sqrt{3}}{2} = 16\sqrt{3}\: \rm units[/tex]
For the same triangle as in case 1 (ie RBQ), but now taking the sine ratio, we get:
[tex]\sin(30^\circ) = \dfrac{|BQ|}{|RQ|} \\\\|BQ| = 32 \times \sin(30^\circ) = 16 \: \rm units[/tex]
This is same as |PA| because of PQBA being a rectangle.
Case 3: Finding the length of AS:The angle PSA is supplement of angle PSR as both joined make a straight line ASR. Thus, we get:
[tex]m\angle PSA + m\angle PSR = 180^\circ\\m\angle PSA = 180^\circ-135^\circ = 45^\circ[/tex]
Thus, for the triangle PSA, similar to the first case or second case, but now using tangent ratio as we've got |PA| = |QB| = 16 units, we get:
[tex]\tan(m\angle PSA) = \dfrac{|PA|}{|AS|}\\\tan(45^\circ) = \dfrac{|PA|}{|AS|} \\\\|AS| = 1 \times 16 = 16 \: \rm units[/tex]
Thus, we get:
Sum of parallel sides = 48 + |BR| - |AS| = 48 + 16√3 - 16 = 32 + 16√3 units
Perpendicular distance between its parallel sides = |PA| = |QB| = 16 units.
Thus, Area of the trapezoid PQRS is evaluated as:
[tex]A = \dfrac{1}{2} \times \text{Sum of parallel sides} \times \text{Distance between those sides}\\A =\dfrac{1}{2} \times (32 + 16\sqrt{3}) \times 16 \\\\A = 256 + 128\sqrt{3} \: \rm unit^2[/tex]
Thus, the area of the considered trapezoid PQRS in simplest radical form is given by: Option c: 256 + 128√3 (in sq. units)
